General Safety Information

WARNING! READ AND UNDERSTAND ALL INSTRUCTIONS.FAILURE TO FOLLOW ALL INSTRUCTIONS LISTEDBELOW MAY RESULT IN ELECTRIC SHOCK, FIRE,AND/OR SERIOUS PERSONAL INJURY.

SAVE THESE INSTRUCTIONS!

Work Area Safety1. Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

2. Do not operate power tools in explosive atmo-spheres, such as in the presence of flammableliquids, gases, or dust. Power tools create sparkswhich may ignite the dust or fumes.

3. Keep by-standers, children, and visitors awaywhile operating a power tool. Distractions cancause you to lose control.

4. Do not let visitors contact the tool or extensioncord. Such preventative measures reduce the riskof injury.

Electrical Safety1. Grounded tools must be plugged into an outlet,

properly installed and grounded in accordancewith all codes and ordinances. Never removethe grounding prong or modify the plug in anyway. Do not use any adapter plugs. Check witha qualified electrician if you are in doubt as towhether the outlet is properly grounded. If thetools should electrically malfunction or break down,grounding provides a low resistance path to carryelectricity away from the user.

2. Avoid body contact with grounded surfacessuch as pipes, radiators, ranges and refrigera-tors. There is an increased risk of electrical shockif your body is grounded.

3. Don’t expose power tools to rain or wet condi-tions. Water entering a power tool will increase therisk of electrical shock.

4. Do not abuse cord. Never use the cord to carrythe tools or pull the plug from an outlet. Keepcord away from heat, oil, sharp edges, or mov-ing parts. Replace damaged cords immediately.Damaged cords increase the risk of electrical shock.

5. When operating a power tool outside, use anoutdoor extension cord marked “W-A” or “W”.These cords are rated for outdoor use and reducethe risk of electrical shock.

6. Connect the tool to an AC power supply thatmatches the name plate specification. Incorrectvoltage supply can cause electrical shock or burns.

7. Use only three-wire extension cords whichhave three-prong grounding plugs, and three-pole receptacles which accept the tools plug.Use of other extension cords will not ground thetool and increase the risk of electrical shock.

8. Use proper extension cords. (See chart.) Insuf-ficient conductor size will cause excessive voltage

drop and loss of power.

9. Keep all electrical connections dry and off theground. Do not touch plug with wet hands.Reduces the risk of electrical shock.

Personal Safety1. Stay alert, watch what you are doing, and use

common sense when operating a power tool.Do not use tool while tired or under the influ-ence of drugs, alcohol, or medications. Amoment of inattention while operating power toolsmay result in serious personal injury.

2. Dress properly. Do not wear loose clothing orjewelry. Contain long hair. Keep your hair,clothing, and gloves away from moving parts.Loose clothes, jewelry, or long hair can be caughtin moving parts.

3. Avoid accidental starting. Be sure switch is OFFbefore plugging in. Carrying tools with your fingeron the switch or plugging in tools that have theswitch ON invites accidents.

4. Do not overreach. Keep proper footing and bal-ance at all times. Proper footing and balanceenables better control of the tool in unexpected sit-uations.

5. Use safety equipment. Always wear eye protec-tion. Dust mask, non-skid safety shoes, hard hat,or hearing protection must be used for appropriateconditions.

Tool Use and Care1. Do not use tool if switch does not turn it ON or

OFF. Any tool that cannot be controlled with theswitch is dangerous and must be repaired.

2. Store idle tools out of the reach of children andother untrained persons. Tools are dangerous inthe hands of untrained users.

3. Maintain tools with care. Properly maintainedtools are less likely to cause injury.

4. Check for breakage of parts, and any other con-dition that may affect the tools operation. If dam-aged, have the tool serviced before using. Manyaccidents are caused by poorly maintained tools.

5. Use only accessories that are recommended bythe manufacturer for your model. Accessoriesthat may be suitable for one tool may become haz-ardous when used on another tool.

6. Inspect tool and extension cords periodicallyand replace if damaged. Damaged cords increasethe risk of electrical shock.

7. Keep handles dry and clean; free from oil andgrease. Allows for better control of the tool.

8. Store tools in dry place. Such measures reducethe risk of electrical shock.

Service1. Tool service must be performed only by quali-

fied repair personnel. Service or maintenanceperformed by unqualified repair personnel couldresult in injury.

2. When servicing a tool, use only identicalreplacement parts. Follow instructions in theMaintenance Section of this manual. Use ofunauthorized parts or failure to follow maintenanceinstructions may create a risk of electrical shock orinjury.

3. Follow instructions for lubricating and chang-ing accessories. Accidents are caused by poorly

maintained tools.

Specific Safety InformationThe Operator’s Manual contains specific safety infor-mation and instructions for your protection againstserious injuries including:

• Electrical shock or burns from contact with wiresor other electrical parts.

Read and follow the safety labels on machine!Know the location and functions

of all controls before using system.

Tool Safety1. Before using, test the Ground Fault Circuit

Interrupter (GFCI) provided with the power cordto ensure it is operating correctly. GFCI reducesthe risk of electrical shock.

2. Extension cords are not recommended unlessthey are plugged into a ground fault circuit inter-rupter (GFCI) found in circuit boxes or recepta-cles. The GFCI on the monitor power cord will notprevent electrical shock from the extension cords.

3. Do not operate the system with electrical enclo-sures removed. Exposure to internal partsincreases the risk of injury.

4. Do not place the monitor and power pack inwater or on a wet surface. Water entering thehousings will increase the risk of electrical shock.

5. Do not use the monitor as a chair or table. Donot drop or shock the monitor. Can result indamage to the unit which increases the risk of elec-trical shock.

Figure 1 – Connectors

There are several pairs of these connectors in thesystem: camera - push cable, push cable - hub, hub -interconnect cable, interconnect cable - monitor/power pack. The above designations are always truefor these connectors. Guide pins are always a differ-ent color than circuit pins, and guide sockets are a dif-ferent size than the other sockets. Align guide pins toguide sockets, ensuring the remaining pins and sock-ets are aligned, and push straight together. To unplug,pull straight out. Wiggle the connector a little, if neces-sary, but DO NOT bend or twist it!

tors, and push rod are built for long lasting use.

The system can be broken down into four sub-assem-blies: camera head, reel/dolly, interconnect cable, andmonitor/power pack. The monitor/power pack is pow-ered by any 120 volt AC source (or 230 volt). In turn,they convert this power to ~12 volt DC to power thecamera head and LED lighting, as well as any optionsin the system. Other than the controls found on themonitor/power pack for such things as brightness,contrast, and LED lighting, the system has no externalbuttons or dials.

The 12 volts DC for the camera (and options) is fed tothe reel through the interconnect cable that is stored onthe dolly. There are three conductors within this cablethat terminate to pins (male) and sockets (female) inthe connectors. See Figure 1 for a detailed description.Pins/sockets #1 and #2 are the supply and return forthe 12 volts DC. Pins/sockets #3 are the return path forthe video signal generated by the camera back to themonitor/ power pack. The connectors on this cable arethe same type that are found at the camera head, pushcable, and any options.

The interconnect cable plugs into the back side ofthe reel into an area called the hub. Inside the hub,there is a device called a slip ring, a kind of rotatingelectrical joint. The slip ring allows the reel to spinwithout twisting the cables that enter/exit the reel,while allowing power and video signals to pass.

The push cable is connected to the slip ring by anoth-er connector inside the reel, on the cone-shaped por-tion. This is the “dry end” of the push cable. Thepower and video signals travel within the push cableto and from the camera head. At the “wet end” of thepush cable, a transition occurs from the stiff rod to aflexible coil cord within the SPRING. This cord hasanother connector that is held into the back of thecamera with a locking sleeve. There are also twostainless steel safety cables within the spring whichprevent the spring from overstretching when pullingthe camera from pipe.

Once the 12 volt DC power enters the camera, itpasses through a circuit board that directs it to eitherthe actual video module, or the lights. There is alsosome protective circuitry to minimize electronic failure.The camera circuitry processes images it receivesthrough the sapphire window and converts it to astandard video signal that returns to your monitor fordisplay. If you have a separate power pack, this signal

Terms(Refer to Figures 2-10)

Brake Large black knob on dolly that controls thespinning action of reel. The purpose of the brake is toprovide a slight drag on the reel to prevent freewheel-ing, resulting in excessive cable exiting the reel. Thebrake is not intended to lock the reel.

Cable Guide The U-shaped metal bar above thebrake that the camera and push cable passes throughas it exits the reel.

Camera Head Contains a video camera module,LED board, and control and protective components for

the video system. The camera is rated to a waterdepth of 330 feet.

Camera Skid The small plastic ring found on thecamera head (not to be confused with centeringguides). Its purpose is to protect the stainless steelhousing from abrasion. A metal C-clip (on the sidethat faces the spring assembly) holds the camera skidin place. The skid should be replaced as soon as itwears down to the grooves, such that it is smooth.

Centering Guides Small, plastic, star-shaped devicesthat mount onto the spring assembly using snap rings.3″ and 6″ in diameter, they center the camera and helpkeep it off of the bottom (out of the sludge).

Connectors All the “plugs” in the system that con-nect the camera; push cable; hub; interconnect cable;monitor/power pack. These are the connectors thathave guide pins (male) and guide sockets (female).These connectors ARE NOT to be confused with 120volt (or 230V) AC outlet plugs, or any video/audiojacks. Refer to Figure 1.

Dimmer A small knob found on the front of monitors,and power packs. This allows control of power to theLEDs to dim or brighten them as conditions vary inpipe. For example, white PVC pipe may reflect toomuch light to the camera, making the picture over-exposed (too bright). Similarly, black ABS pipe willreflect much less light, making the picture underex-posed (too dark). Adjustment of the dimmer allowsfine control of the LED lighting for an optimum picture.

Dolly Metal frame that the reel is mounted to. Thedolly has a second set of feet on the back side of thereel, allowing the system to rest on its side (open-end-up) for greater stability. There are also three fittings(with capped covers) that allow attachment of theoptional auxiliary handle.

Hub The center, cone-shaped portion of the reel.Within the hub is the slip ring and axle.

Interconnect Cable Thirty-three foot cord that plugsbetween the output of the hub and the monitor/powerpack. It is kept stored on the dolly, and left pluggedinto the hub.

LED Light Emitting Diode. Solid-state light that, unlikean incandescent lamp (a regular light bulb), does nothave a fragile filament. These give off red light to illumi-nate pipe interiors. The camera module is especiallysensitive to red light, resulting in a higher quality picture.

LED Ring The polycarbonate (plastic), donut shapedring that protects the LEDs from abrasion. There is also

Tilt Stand Small kick stand on bottom of Monitors.

This helps raise the angle of the screen when the

a metal ring embedded around the perimeter of theLED ring that helps extend the life of this component.

Locking Sleeve This device is found at the rear ofthe camera, within the spring. It holds the connector inplace and serves as an anchor for the safety cables.This device is unscrewed from the back of the camerato detach the connector from it.

Monitor The “television” in the system. RIDGID/Koll-mann monitors include the power pack within themand have a dimmer knob to adjust the LED brightnessfor varying pipe conditions. They also include a sun-shade, tilt stand, handle, and AC cord storage hooks.

Power Pack This component is supplied with sys-tems where a monitor is not ordered. The power packconverts 120 volt AC (or 230V) power from a wall out-let to ~12 volts DC power to run the camera head(video and lights), as well as any options. Its featuresinclude a power switch, connector (female to intercon-nect cable), a dimmer, and a video out jack providinga signal to your monitor.

Reel The gray plastic portion of the system that holdsthe push cable and camera.

Safety Cables Stainless steel cables (two) within thespring assembly that connect between the push cabletermination and the locking sleeve holding the con-nector at the back of the camera head. These preventthe spring from over-extending when pulling the cam-era out of a pipe. Together, they provide over 800pounds of breaking strength.

Sapphire Window The small, round port that thecamera “looks” through. This component is virtuallyscratch-proof providing excellent video throughout thelife of the system.

Spanner Wrench 0ne-piece wrench used to engagethe end of the spring when removing the camerahead. To remove the camera from the spring, youmust use a spanner wrench.

Spring Assembly Flexible stainless steel spring andassociated components that hold the camera to thepush cable, provides a flexible transition from camerato push cable, and protects the terminations within thespring.

Sunshade This metal device is included on monitorsto protect the screen when system is not in use(closed) and to optimize the picture in bright sunlight(opened).

The sunshade on this monitor has been locked open,and the tilt stand is engaged. Close the sun shadewhenever the monitor is not in use. Always adjust thesettings below for each inspection to ensure the opti-mum picture.

Set Up and OperationNOTE! The rims of the wheels are flat on one side, con-

vex on the other. To make the wheel stance aswide as possible (more stable), the flat edgeshould face outward when the wheels aremounted.

To Install the Wheels Onto the Dolly1. Position the axle so that the side with the rubber

foot is on the same side as the other two rubberfeet on the dolly frame. Slide one wheel onto theaxle with the flat edge facing outward.

2. Slide the axle and wheel through one frame mount(on the side with the rubber feet), then through theplastic spacer. Slide the axle through the otherframe mount.

3. Slide the second wheel onto the axle with the flatedge facing outward. Slide the washer onto theaxle (outboard of the wheel); then insert the cotterpin at the far end of the axle.

Models with Power Packs1. Find the power button at the front of the power

pack, and make sure it is switched OFF. Plug thepower pack’s power cord into an approved outlet.

2. Unwrap the interconnect cable from its storagehooks on the dolly. Plug the loose end of this cordinto the mating connector at the rear of the powerpack, referring to Figures 1 and 8.

NOTE! Figure 1 demonstrates the proper way to plugconnectors together. This is true in all cases.For example, the camera head will plug directlyinto the back of the monitor/power pack, usingthese guidelines.

3. Locate the small video cable that came with thepower pack. Plug either end of it into the small jackat the rear of the pack labeled video out. (Thesetypes of connectors are called RCA jacks.) Mostlikely, your monitor will have the same type of con-nector for video in. (If not, it has a connector calleda BNC jack.)

4. Plug the remaining end of the video cable into therear of your monitor at the video in jack.

5. Turn the monitor ON, then the power pack. You

should now have a picture on the screen. If the pic-ture doesn’t look perfect, you can adjust the con-trast, brightness, and horizontal/vertical hold onyour monitor, as well as the brightness of the cam-era head LED lighting using the dimmer knob locat-ed on the front of the power pack.

NOTE! If you do not have a picture, make sure you havefollowed the above steps correctly, checking tosee that the video cable is plugged in and the120V (or 230V) source is actually working.

Models with RIDGID/KollmannSeeSnake Provided Monitors1. Gather the reel/dolly and monitor in a convenient

area near a 120V (or 230V) AC power source.

2. Unwrap the interconnect cord from its hooks locatedon the back side of the dolly. Plug this cord into theconnector at the rear of the monitor, referring toFigure 1 for the proper way to make the connection.

NOTE! Figure 1 demonstrates the proper way to plugconnectors together. This is true in all cases.For example, the camera head will plug directlyinto the back of the monitor/power pack, usingthese guidelines.

3. Lift and lock open the black sunshade that coversthe screen of the monitor.

4. Plug the power cord for the monitor into a standard120 volt outlet (or 230V).

5. Locate the power button at the lower-left, front ofthe monitor and depress it. In a few moments youshould have a picture. You may need to adjust thebrightness and contrast of the monitor. This can beaccomplished by adjusting the dials to the right ofthe power button. The one represented by a sunabove it is the brightness, and the one with the par-tially-shaded circle above it is the contrast. You canalso dim or brighten the cameras lighting with thedimmer knob, located on the lower-right, front ofthe monitor.

NOTE! These adjustments will be more accurately madewhen the camera is positioned in a section ofpipe. If the picture still does not look right, orthere just isn’t one, carefully review the abovesteps to ensure they were properly followed.

Hooking Up VCR SystemsWRONG

These types of connec-tors, commonly referred toas F style and labeledUHF/VHF, are the incor-rect input jack at the rearof the VCR for recording.Trying to input a video sig-nal through this jack willnot work. These are usual-ly labeled UHF/VHF, andare for cable TV or anten-na input.

NOTE! The video cable supplied with every system willnot mate with this connector. The F-style con-nector on your recording device may look slight-ly different.

RIGHT

This type of connector, anRCA (female) jack is thecorrect jack for input to theVCR. Usually, this jack willbe color-coded yellow, andwill be la-beled VIDEO IN.

NOTE! The video cable supplied with every system hasthe correct mate for this connector. If your sys-tem included a monitor, an adapter is suppliedto mate with its video out jack. power packshave a female RCA video out jack (like shown),for comparison.

Hooking up a VCR or Camcorder

Refer to VCR/camcorder manual for proper cable dia-grams. To hook up the VCR/camcorder to a RIDGID/-Kollmann SeeSnake monitor or power pack:

1. Locate the video cable that came with the system.This cable has “male” RCA jacks on either end forthe power pack. An adapter (BNC-to-RCA) is sup-plied to mate this cable with the video out jack onour monitors.

2. Plug one end of the video cable into the RCA videoout jack at the rear of the power pack or twist andlock the adapter-end onto the video out jack at therear of the monitor.

3. Plug the other end into the RCA-style, video in jackfor your VCR/camcorder.

“RCA” style, Video In

“F” style, UHF/VHF

NOTE! Do not attempt to use any F-style, UHF/VHFjacks (above left) on your recording device asthe video input jack. Use only RCA-style jackslabeled VIDEO IN.

Recording to a VCR

Consult the manual of your VCR for the correctchannel required when using its video in jack.Depending on the make, this may be called line a,line b, or av1. (DO NOT assume this will be CH.3/CH. 4.) Follow the manual for your VCR to recordvideo from an external source.

Recording to a Camcorder

Consult the manual of your camcorder for record-ing from an external source (via its video in jack).This function is usually selected with a switch, oftenlabeled camera/vcr.

Playing a Video Tape from a VCR/Camcorder tothe RIDGID/Kollmann SeeSnake

1. Unplug the system from the monitor to disconnectany video signal from the camera to the monitor.

2. Hook up the video cable from the video out jack ofthe recorder, to the video in jack of the monitor.

3. Follow the instructions in the VCR/camcorder man-ual for video tape playback to a monitor.

4. DO NOT store or transport the monitor with theadapter and/or video cable installed.

Solutions to Common Recording Problems

1. If the jack on the recording device is not an RCAjack labeled video in, it is probably not the correctinput.

2. When making a video recording, ensure the videocable runs from video out on the monitor, to videoin on the recording device (NOT the other wayaround).

3. When reviewing a tape on the monitor, ensure theinterconnect cord from the reel to the monitor isunplugged. If not, the image from the camera andthe tape will combine producing a noisy picture.

4. Do not run video in and video out cables from theVCR to the monitor simultaneously. Use eithervideo in or video out at any one time.

Pre-ChecksMechanical Checks

1. Check the cotter pin that holds the axle in place toensure it is fully engaged. The wheels should bothspin freely.

2. Rotate the reel brake to a position that allows youto easily pull cable from the reel, yet stops immedi-ately when you aren’t retrieving cable. For trans-port, add more friction to the brake.

3. Grasp the spring assembly in one hand, and thecamera head in the other. Ensure the spring istightened ONLY to the point where the cut end of itis as far as it can go in the camera head’s threads.If it is undertightened, you should be able to physi-cally screw the spring a little farther onto the cam-era’s threads. If it is overtightened, the cut end ofthe spring will “crawl” up and over the threads. Ifthis occurs, follow the procedures in the“Maintenance – Removing the Camera Head” sec-tion to properly seat the spring using the spannerwrench provided.

4. Check to see that the connector at the end of thepush cable is fully seated into the connectorattached to the cone-shaped portion of the hub(inside the reel). Likewise, check that theInterconnect cable is completely plugged into thehub. Periodically inspect these connectors for goodconnections as the system is used.

Electrical Checks

The system should always produce a crisp picturethat is free of noise and lines. Sometimes, especiallyduring cold-weather conditions, it can take a momentfor the system to heat up before it will produce theoptimum picture. Otherwise, check that connectorsare fully engaged and follow these guidelines:

1. With the system energized, look to see that aneven amount of light is coming from the LEDs.Place the camera in the reel, and give it a goodspin while watching your monitor.

2. At the rear of the RIDGID/Kollmann monitor a smallswitch can be found below and to the right of thevideo in jack. It has two settings: 75 ohm and HighZ. For almost every application, the switch shouldbe set in 75 Ohm position. Sometimes when usinga VCR with the system, the High Z position isrequired. Refer to your VCR manual to select thecorrect position.

3. Find a section of pipe that is 2-6 inches in diame-ter. Roll a page of newspaper or business station-


10 Test Equipment Depot - 800.517.8431 - 99 Washington Street Melrose, MA 02176 - TestEquipmentDepot.com

ary into the pipe and watch the monitor. The pictureshould be clear and the lighting should be even onthe pipe walls. Try adjusting the contrast andbrightness, as well as the lighting (using the dim-mer knob on the monitor/power pack) to obtain thebest picture. Remember, as the materials of pipevary, it will be necessary to adjust these settings tomaximize picture quality on different jobs. Forexample, white PVC pipe requires less lighting thanBlack ABS. As experience is gained with the sys-tem, operators will learn that slight adjustments inthese settings can highlight problems within a pipe.

At the Job Site1. The camera can almost always be pushed far-

ther when grip-style rubber gloves are worn. Itis much easier to get a grip on dirty push cable,and the gloves also keep sludge off the hands.

2. Properly positioning the equipment before youbegin an inspection will save time, be morecomfortable, and minimize the potential forequipment damage. Set the monitor in an areawhere it is unlikely to fall, and where it can beviewed while you are pushing the camera. Agood location is right next to the cleanout or entrypoint. Be sure to keep it from getting wet.

3. Set the reel about 6 to 8 feet from the entry. Thiswill provide ample cable to grasp and developmomentum without having a lot of slack draggingon the ground. Slack can be alleviated by puttingfriction on the reel using the brake. If it is set cor-rectly, push cable will only come off the reel whenyou pull on it.

4. Always try to run water down the pipe undergo-ing inspection. This will keep the system muchcleaner, and allow you to push noticeably fartherwith less friction. This can be accomplished byfeeding a hose with a small amount of flow into theentry or occasionally flushing a toilet that drains tothe pipe. If the water is preventing you from seeingan area of importance, temporarily turn it OFF.

5. When pushing, the end of your stroke shouldbe as close to the entry as possible. Standingtoo far back, with an excess of cable between yourhands and the entry may cause the cable to fold onitself outside the entry.

6. Folding the push cable on the sharp edge of anentry can cause it to snap. Extreme cautionmust be used to minimize the chance of bend-ing the push cable on sharp corners. This is acommon cause of push cable failure, and all opera-

tors should be aware of this. If the camera justdoesn’t seem to want to go any farther, DON’TFORCE IT! If another entry is available, try it.

7. When inspecting a pipe, it is usually necessary togive a little extra push in the bends. Back up, if nec-essary, and “pop” the camera through a turn usingthe least amount of force required. Try to be asgentle as possible, and don’t hammer or snap thecamera head through corners. After some practice,you may learn that the best way to inspect a sec-tion of pipe is to push the camera through quickly,then draw the camera back home slowly and even-ly. It is always easier to control the camera whenpulling than when pushing.

8. Make sure the sapphire window is clean prior toentry. Some users claim that a slight film of deter-gent on the lens minimizes the possibility of greasesticking to the port. In any case, take advantage ofany standing water in the pipe to wash the front ofthe camera by jiggling it in the water. Flushing thepipe with water supplied by a hose or periodicallyflushing a toilet can help keep the port clean andimprove performance by reducing cable friction.

9. Take advantage of the lighting to keep track ofwhere the camera is headed. If the particular pipeyou are inspecting is easier to evaluate with otherthan the maximum lighting, periodically maximizethe lighting (using the dimmer knob on the moni-tor/power pack) to get a look at what lies ahead. Beaware of any obstructions, such as a crushed sec-tion of pipe or excessive hard build-up, that mayprevent retrieval of the camera. do not clearclogged lines with the camera head!

9. Pipe materials and conditions vary. Adjustment ofthe contrast and brightness settings, as well as thelight dimmer after the camera is within the pipe,can greatly increase picture quality. This is particu-larly important when your customer is supervising,and when making recordings.

10. Whenever possible, lay the system on its side feetfor even greater stability. This is also preferred whenon a rooftop (entry through a roof vent) or hillside.

11. If local 120V (or 230V) AC power for monitor is notavailable, you can operate the system using a volt-age converter that plugs into your vehicle’scigarette lighter. They convert your vehicles 12 voltDC to 120 volts (or 230V) AC. As long as you arenot rewinding and fast-forwarding video tapes fre-quently, this method of powering the system can bedone safely on a good battery for several hours.


11

12. The system can travel through multiple 45 and 90degree bends and wyes. Do not, however, try toforce it through a P-trap or T if there is a largeamount of resistance.

13. Do not attempt to remove or store push cable onthe reel solely by turning the reel itself. Release thebrake enough so that you can manually push orpull cable from the reel and wind or unwind it.

14. Be careful in T-entries not to fold the camera backon itself, this could cause camera to stick.

NOTE! Some customers have reported success in con-trolling camera entry into hard Ts using a “shoehorn” made from a length of 1-inch copper pipeof the necessary length to reach the T that hasbeen flattened and curved at the end. With thisdevice, you can position the curved portion intothe side of the T where entry is preferred andguide the camera in the proper direction.

MaintenancePreventative MaintenanceCamera Head

1. The camera head requires little maintenance, otherthan keeping the LED ring and sapphire windowclean. Use a soft nylon brush, mild detergent, andrags and sponges from the camera head up to (butnot including) the monitor/power pack.

2. When cleaning the camera, do not use scrapingtools as they may permanently scratch these areas.NEVER USE SOLVENTS to clean any part of the sys-tem. Substances like acetone and other harshchemicals can cause cracking and crazing of theLED ring, which could affect waterproofing.

3. As you use the system more and more, you maybe surprised to find that scratches on the LED ringwill have a minimal effect on the performance of thelighting. Don’t sand the LED ring to removescratches, as it is part of the watertight housing.

4. Another good way to extend the life of the camerais to avoid removing obstructions from pipe with thecamera head.

Spring Assembly

1. The spring assembly is the area where foreign mat-ter is most likely to accumulate. Within the spring isthe splice between the push cable and a connector(and maybe a sonde unit for a pipe location sys-tem). Should sharp objects or harsh chemicals beallowed to remain in this area for long periods, theymay wear on these components. Stretch the spring

end-to-end as far as the internal safety cablesallow to check this area. Stretch again and stir in abucket of warm water and mild detergent to flushthis area.

Push Cable, Reel/Dolly

1. The push cable and reel/dolly require almost nomaintenance. (Of course, a clean system will lastlonger and be more impressive to your customers.)It is important, however, to keep the push cableclean to spot any excessive cuts or abrasions,while making it much easier to grasp and push.

NOTE! Whenever you are retrieving push cable into thereel, an excellent way to cut down on cablegrime is to run it through a rag in the last handthat touches the cable as it enters the reel. Foran overhaul cleaning, lay the system on its sidefeet and fill the reel with lukewarm water and amild detergent. Leave it overnight and spin itoccasionally. Remove the water prior to use andrun a rag over the cable.

Monitor/Power Pack

1. The monitor/power pack requires a little more care.The same is true for any monitor in the field. Unlikethe rest of the system, the monitor/power packaren’t waterproof. Clean them with a damp cloth,and ensure foreign matter does not get into anycooling vents. Always avoid dropping or shockingthese components.

Corrective Maintenance

Removing Camera Head

The system has been designed so that the camera head can be removed for troubleshooting, installing the transmitter, or to use in a different application on a separate cable.

1. Pay out enough cable to place the camera andspring assembly on a work bench or other conve-nient work area. Set the brake to prevent the reelfrom spinning.

2. Locate the metal spanner wrench that was provid-ed with the system and hook the cut end of thespring (directly behind the camera head) with thebusiness end of the spanner and turn the cameraoff the spring (Figure 11). The camera should nowbe hanging by its locking sleeve and safety cables(Figure 12).

3. Grasp the ribbed portion of the sleeve with onehand and the camera and cables with the other.Rotate the ribbed portion of the sleeve (counter-


12

clockwise when camera is viewed from the rear) tounscrew it from the camera. If it is difficult to turn,get it started with a pair of pliers (Figure 13).

4. When the sleeve is completely unscrewed, slide itdown the black cord so that the actual connector isexposed. Grasp the connector in one hand and pullit straight out of the back of the camera. Wigglingthe connector slightly, side-to-side, may help breakit free (Figure 14).

Figure 11

The spanner wrench is hooked into the end of thespring. The camera is then rotated (counter-clockwisewhen viewed from front) with the other hand.

Figure 12

Once the camera head is removed from the spring,the locking sleeve can be seen holding the connectorto the back of the camera. The safety cables aremounted to a rotating portion of the sleeve, whichhelps prevent their twisting.

Figure 13

The locking sleeve has been removed by the cameraback by rotating it counter-clockwise (when viewingthe camera from the back). The connector is now allthat holds the camera on.

Figure 14

The camera head is now removed. Note that theseconnectors are the same style as those found through-out the system.

Locating Faulted Components

The basic idea in troubleshooting the system is to usethe camera head to eliminate suspected components.Here are the areas we will try to isolate the fault to:camera head, reel/dolly, interconnect cord, monitor/-power pack. As a scenario, we will assume that thesymptom is no video, no lights.

1. Remove the camera from the spring assembly.

2. With the monitor/power pack set up for operation,plug the camera head directly into the back of themonitor/power pack where the interconnect cableis usually connected. Turn on the system andcheck the monitor for a picture. If there is a goodpicture with proper lighting, the problem is some-where between the interconnect cable and thespring assembly. Proceed to step 4. If there is nopicture, the problem is probably in the camera heador monitor/power pack.

3. To virtually eliminate the monitor, play a tape onyour monitor with a VCR through the video in jackat the rear (VCR – video out; monitor – video in). Ifyou get a good picture, it is almost certain the prob-lem is in the camera head. The power pack is a lit-tle more complicated to troubleshoot, so contactRidge Tool Company if you suspect it is faulted.

4. Plug the interconnect cable into the monitor/power-pack. Unplug the other end of the interconnectcable from where it plugs into the reel-hub, andplug the camera head into this end. Turn on thesystem and check the monitor. If you get the videoand lights back, the problem is likely in the pushcable or hub. If there is no picture, the interconnectcable is the likely fault.

5. Once you suspect a component, contact Ridge ToolCompany Technical Services. We will establish aplan of action to get your system back on line.

6. For additional troubleshooting suggestions, pleaserefer to Chart 1.

Re-Installing Camera Head

1. Lay out enough cable to lay the spring assembly ona convenient work area and set the brake.

2. Plug the connector at the spring assembly into thecamera head, making sure that the guide pins/sock-ets are aligned.

3. Grasp the camera head and safety cables with onehand and turn the ribbed portion of the lockingsleeve to screw it into the back of the camera.

IMPORTANT: Try not to twist the cord or the camera,only the locking sleeve. If this is doneproperly, the cord and safety cables willnot be twisted around each other whenyou view them from between the windingsof the spring.

4. Once the locking sleeve is tight into the back of thecamera, thread the spring onto the camera and,using only your hands, screw the camera onto thespring.

NOTE! The camera head will be properly mounted whenthe end of the spring is snug between the cam-era and the thread (not so far that it begins toraise off the threads) and you cannot manuallyunscrew the camera.

Transportation & Storage1. Slip the camera into the reel with the rest of the push

cable. Turn the brake clockwise enough so that thereel does not rotate unless you manually turn it.

2. Unplug the interconnect cable from the moni-tor/power pack and wrap it loosely onto its storagehooks located on the dolly.

3. If space allows, the reel/dolly should be laid on itsside during transportation and use. You will noticethat there is a second set of feet (three) on the sideof the reel where the interconnect cable is stored. Ifthere is not enough space to lay the system on itsside, stand it up and run a strap or cord through thedolly and secure it to the vehicle.

4. Close the sunshade over the screen of the monitorand wrap its outlet cord onto the hooks provided atthe rear.

5. Keep spare parts, tools, and the manual secure ina work bag to protect them when not in use.

6. When possible, keep the system stored in a cool,safe place. Leaving the camera pointed into thesun or a high powered light source (when operat-ing) can damage the imaging chip.

OptionsCentering Guides: 3″ and 6″The centering guides are designed to help center thecamera in various sized pipes, and also help keep thecamera out of the bottom sludge. Picture quality isimproved as they help position the camera towardsthe middle of the pipe. This allows the camera to seean equal amount of the pipe wall in all directions.

Do not assume that the guides are only helpful in 3″and 6″ pipe! They also help in larger pipe by bringingthe camera closer to center and raising the cameraout of the sludge that is often found below the waterline. Keeping the camera off the bottom of the pipekeeps the front of the camera cleaner, longer.

It is recommended that guides be used whenever pos-sible (3″ and up) as they protect the system from wearand tear. However, if you are having trouble going fur-ther in a particular pipe, try it without the guides. Thebest advice is to experiment with local conditions anddecide what is best for the given job. One way toincrease their flexibility is to pre-strain them by bend-ing the spikes back and forth a few times before use.

To install the guides, wind two metal snap rings perguide into the push cable just like you would slip a keyonto a key ring. You should usually use 3 guides.Position each guide where you want it on the spring,with one of snap rings on either side. Look for grooveson either side of the spikes on the guide and wind asnap ring into each groove to lock it onto the spring.When it is time to remove them, lift the edge of thesnap rings out of the grooves with the tip of a smallscrewdriver and unwind them from the grooves. Slipthe snap rings off the spring/push cable and storethem with the guides for later use.

Pipe Location TransmitterThe pipe location transmitter allows the user to pin-point the location and depth of the camera headgreater than 10 feet underground in cast iron pipe.The transmitter emits a 512Hz signal that is sensed bythe receiver. The transmitter is designed to work withmanufacturer’s receivers who use 512Hz.

One of the great features of our transmitter is that it ispowered by the same power supplied to the camerahead. Once installed, it is always ready for use,

whether or not you choose to bring the receiver alongon the job. There are no batteries or extra cablesrequired, and the system still travels the hard 90degree bends.

Installing the Pipe Location Transmitter

1. Remove the camera head from the spring assem-bly. (See Corrective Maintenance – RemovingCamera Head section.)

2. With the camera head removed, you can see thatthe connector passes through the locking sleeve,and that there is a rounded ridge on the connectorthat prevents it from slipping out the rear of the lock-ing sleeve. You want to carefully push the connec-tor out the back of the locking sleeve (Figure 15).Use a blunt object, such as the eraser-end of a pen-cil or a finger to push on it, while pulling on it fromthe back. Don’t grasp the coil cord when pulling,grasp the connector! You can lube the connector tomake it easier, if necessary. be careful not to dam-age the sockets of the connector by pushing on itwith a sharp object, like a screwdriver.

CAUTIONBe sure to use non-conductive lubricant. a sili-cone lubricant is suggested.

Figure 15

After removing the camera head, slip the coil connec-tor out of its locking sleeve. Some silicone lubricantmakes removal much easier. Keep the stainlesscables untwisted by holding the sleeve and rotatingthe ring on it that the cables are attached to.

Figure 16

On the transmitter, unscrew the plastic locking sleeve.Place the plastic locking sleeve (leading with thetapered end) over the coil connector. Again, some sili-cone lubricant makes this easier.

Figure 17

Push the coil connector onto the leads making surethat it is fully seated. Screw the plastic locking sleeveback onto the transmitter.

Figure 18

When completed, grasp both ends of the springassembly and stretch it to draw the transmitter inside.Check that the coil cord and stainless cables are situ-ated properly. Push the camera-end of the transmitterback through the locking sleeve using some siliconelubricant, if necessary. Re-install the camera head.

3. On the transmitter, unscrew the plastic lockingsleeve. Place the plastic locking sleeve (leadingwith the tapered end) over the coil connector(Figure 16). Again lubricant makes this easier.

4. Plug the coil cord connector into the rear of thetransmitter, making sure that it is fully seated.Screw the plastic locking sleeve back onto thetransmitter (Figure 17).

5. Carefully insert the transmitter into the springassembly ensuring that no cabling gets bent orwedged between the transmitter and the springassembly. You can stretch the spring assembly,end-to-end, to help draw the transmitter into it.

6. Push the female connector of the transmitterthrough the metal locking sleeve (Figure 18). Usesome silicone lubricant on the exterior of the con-nector, if necessary.

7. The system should now look like it did when youfirst removed the camera head, except the trans-mitter is within the spring assembly. Re-install thecamera head. (See Re-Installing Camera Headsection.)

8. Refer to the manual provided along with yourreceiver for operation of the location equipment.

Auxiliary HandleThe auxiliary handle attaches to the three fittings onthe frame that are covered by plastic covers. Thishandle greatly improves the stability of the systemwhen rolling, particularly for taller operators.

To install the handle, insert the auxiliary handle fittingsinto their respective mounts on the frame, and lock intoplace using three sets of bolts/crown nuts supplied.
