ULTIMATE DRILLING MACHINE
OPERATING SUMMARY
STARTING: The function switch at the rear control panel must be in the center START / DRIVE position and the MASTER DISCONNECT switch must be on. Be certain both red STOP switches are pulled out. The engine throttle, choke and start key are all at the rear of the engine. MOVING: The self‐propelled function only works with the function switch in the START / DRIVE position. Gently raise or lower the lever on the drive valve mounted at the upper right rear of the machine. To steer the unit, lift the rear tires off the ground and pivot to the proper direction. The machine may also be moved manually by lifting the rear tires off the ground and pushing or pulling. Be certain the rear legs and front mast are raised up for maximum ground clearance. HYDRAULIC OUTLETS: The function switch must be in the lower HYDRAULIC OUTLETS position. It is best to attach the hoses before switching to this function or with the unit off. Flow to the outlet is controlled by a cartridge at the top of the main hydraulic manifold. This cartridge should normally be left in the OFF position until flow is required. Due to internal pressure loss, the pressure at the rear pressure manifold (quick connects) will be less than that at the gauge on the main manifold. DRILLING: The labels at the front controls summarize the typical drilling operation. Please read them and review the following additional information. After positioning the drill, put the function switch in the upper DRILL position. This activates the controls at the front panel. Be certain the circuit breakers at the rear electric outlet panel are on as AC power is needed for the vacuum pump.
The DRILL DOWN, DRILL UP, and TURBO switches are intermittent and must be held to operate. Holding UP or DOWN and TURBO will raise and lower the drill more rapidly for initial positioning or pulling a bit out of a hole. To adjust the speed of cylinder stroke hold the up or down switch and turn the small black knob at the top right of the main hydraulic manifold. This is also the maximum speed the drill can move while in the AUTO DRILL mode and should be set slow. With the drill set to the proper RPM, gently jog the DOWN switch to slowly start the hole. Once contact is made, switch to AUTO DRILL. Drilling will continue until the cylinder strokes to its maximum length or until the AUTO DRILL switch is turned off. The DRILL DOWN, DRILL UP, and TURBO switches will not operate when in the AUTO DRILL mode. TWO SPEED DRILL MOTOR: Set to high speed for drills up to 10” Diameter (Shift Clockwise) and low speed for drills greater than 10” (Shift Counter Clockwise). COUNTERWEIGHT: For smaller bits it should be removed and stored or mounted at the front frame position. The rear position is recommended for 16” bits and larger when the machine becomes front heavy.
IMPORTANT! A red emergency stop button is at the rear and side control panels. This will stop the engine and shut down all hydraulic and electric circuits. These buttons must be in the out position to start the engine

reverse. 4. Steer the unit by lifting the rear tires off the ground
and pivoting to the desired direction.
WARNING Use extreme caution when
operating the machine on slopes, as it is more susceptible to sideways tipping/rolling over, especially with a full water tank.
Electrical Outlets and Circuit Breakers
WARNING DO NOT use the electrical outlets for external
equipment that requires more power than the outlets are rated for.
The electrical outlets are powered by a 5000 Watt generator when the engine is running. The outlets are single phase 115 and 230 Volt twist locks and a 115 volt GFI (ground fault interrupt). The circuit breakers provide system protection and can be left on at all times.
Electric Switches
The STROBE light, SPOT light, WATER PUMP, REAR and FRONT raise/lower electric cylinders are all12 volt DC and will operate with the engine off and the Master Disconnect ON (Figures 2 and 3). Take care not to run down the battery if the engine is not running. The engine must be running for all other switches to operate
Figure 13: Electrical Outlets and Circuit Breakers
Hydraulic Outlet Mode
Figure 14: Hydraulic Outlets
Flow is controlled by a cartridge at the top of the Main hydraulic manifold (Figure 3). This cartridge should normally be left in the OFF position until flow is required. Pressure: The Main Relief valve is typically set to 2100 psi on the front 3000 psi pressure gauge (Pressure higher than 2100 psi will stall the engine). Lower pressures may be set if required for a particular tool. To Adjust Pressure 1) The unit must be in the hydraulic outlet mode with no hoses attached. This will force the system pressure to maximum. 2) Move the flow control cartridge away from zero.
13
3) The pressure can now be adjusted by turning the knob on the main relief cartridge (Fig. 3) Note: Due to internal pressure loss, the pressure gauge located at the rear hydraulic outlets will show less pressure than the gauge at the main hydraulic manifold. Attaching External Tool: It is best to attach the external hoses to the UDM before switching to the hydraulic outlet function or with the unit off as even very low residual internal pressure can make attaching hoses difficult. Be certain connections are clean! WHEN FINISHED 1. Turn off the hydraulic tool or the flow adjuster on the
tool. 2. Turn the flow cartridge off. 3. Move the function switch to Start/Drive. 4. Disconnect the external hoses. 5. Turn off the engine.
Hoses: Large diameters and short lengths are preferred and offer the highest system efficiency. If one is operating 50 ft (15.2M) from the power source, there is also a 50 ft (15.2M) return for a 100 ft (35.5M) total hose length. With 12 GPM and oil at 100 deg. F (37.8C), this could result in a 300 psi (20.6 Bar) pressure loss with ½” hose and a 100 psi (6.9 Bar) loss with 5/8” hose. Pressure loss will change dramatically with oil temperature.
WARNING Keep all body parts away from
areas that may eject hydraulic fluid. Pressurized hydraulic fluid can penetrate the skin, causing serious injuries. Seek medical attention immediately!
Water System
The water system consists of the stainless water tank, a 12 volt DC water pump and various hoses, fittings and valves. The primary purpose is to cool the core bit and flush slurry from the hole. Note: Always test the water supply for adequate pressure and flow prior to drilling.
Figure 15: Water Tank
Filling the Water Tank
Fill the water tank as required. The clear hose at the rear of the tank shows the water level. Left and right fill ports are provided for convenience.
Using the Water Supply
1. Open the supply valve directly under the tank center (Not the large drain valve, near the side of the tank).
2. The master disconnect switch must be on. 3. Turn on the water switch at the front panel. The
spray hose will now function.
For drilling
4. Open the manual valve mounted in the front control panel (Figure 3).
5. Adjust the adjacent ball valve to increase or decrease flow to the bit. This valve may be left in this position.
6. After drilling, shut off the manual valve. 7. Turn off the Water switch. NOTE: Too much water makes the slurry look clear and wastes water. Insufficient water makes the slurry thick and pasty and could result in a core sticking in the bit. Draining the system 1. Be certain the area is safe for dumping water. 2. Open the large valve below the water tank and accessible through the side cover plate. 3. Repeat steps 1-7 to drain water from the drill circuit and spray hose (if required). 4. For complete drainage, remove hoses from the water pump. Sliding tabs at the pump ports will quickly release the hoses. Complete drainage is only required if freezing may occur or for long term storage.

Figure 16: Water Release Valve
Vacuum System
WARNING DO NOT stand on the machine to
act as an anchor.
The vacuum system is only used during the drilling operation when the base is firmly on the ground. It adds stability to the system and should be used whenever possible. Cleaning and wetting the surface with the garden hose helps create a good seal.
Figure 17: Vacuum Base
Using the Vacuum
1. Turn on the circuit breakers as 115V is required. 2. Close the vacuum valve at the front panel (Fig. 3). 3. Turn on the Vacuum switch. 4. To release the vacuum, open the valve and turn off
the Vacuum switch. Vacuum Gauge The vacuum gauge indicates that the vacuum system is working. Vacuum pressure should range up to ~25” Hg.
NOTE: Poor vacuum may indicate loose hose fittings, loose water trap jar, worn vacuum base seal, or the base may be on a cracked or scored surface where vacuum is not possible. Water Jars These jars are mounted adjacent to the vacuum pump and help keep water and other contaminants from being sucked into the pump. Visually inspect and empty these jars on a regular basis. The jars unscrew by hand. Failure to empty these two jars will result in vacuum pump damage.
Figure 18: Water Jars
Drill Mode
Introduction and Initial Settings: The following items can only be used or adjusted with the function switch in drill mode. The recommended pressure settings are maximum limits. They will typically only be reached intermittently if rebar or hard spots are encountered while drilling.
Cylinder Pressure The pressure at the base end (top) of the cylinder controls how hard the bit is pushed into the ground. This is limited so the machine can provide sufficient down force yet never lift itself of the ground. The pressure is monitored on the 500 psi gage at the front of the main manifold (Figure 3). This pressure is adjustable with an Allen wrench at the relief cartridge at the front of the main manifold. It is factory set to 200 psi and should rarely need adjustment.
1. The unit must be in the drill mode. 2. Set the drill RPM to zero. 3. Fully extend the cylinder without contact or push
against the ground (drill down switch) as if trying to lift the machine off the ground. This will force the cylinder pressure to maximum.
15
4. The pressure cartridge can now be adjusted with an Allen wrench while holding the drill down switch.
5. Retract the cylinder with the drill up switch.
NOTE: Use caution and judgment if increasing the pressure beyond 200 psi as the machine may drill faster, but the possibility of jammed bits increases. If drilling without vacuum, do not exceed 200 psi.
Cylinder Speed
While holding the drill down switch, turn the small black knob at the top right of the main hydraulic manifold (Figure 3). This sets the maximum speed the drill can move (unless in turbo mode) and should be set to the slow end of adjustment. Slow speed is particularly important at initial drill to ground contact. This setting should rarely need adjustment.
Drill Motor Pressure
This pressure generates the torque to spin the bit. It is controlled by the main relief cartridge at the front of the manifold and is monitored by the 3000 psi gage. This pressure should be set above 1500 psi for drilling and it is adjusted exactly as if setting hydraulic outlet pressure. Setting it below 1500 psi could result in stalling the drill motor. It can typically be left at 2100 psi at all times. 1. The unit must be in the hydraulic outlet mode with
no hoses attached to set this pressure. This will force the system pressure to maximum.
2. The pressure can now be adjusted by turning the knob on the main relief cartridge (Figure 3).
3. Switch out of the Hydraulic Outlet mode. Drill Motor Pressure Switch A non-adjustable pressure switch monitors the drill motor pressure and will automatically shift the cylinder to neutral (stops pushing) if it senses the drill motor pressure rising above 1500 psi (hard spots). The cylinder will thus automatically cycle on/off as the drill works through rebar or other hard spots.
Counterbalance Valve
A counterbalance valve is in the cylinder circuit to hydraulically lock the cylinder in position when the machine is off. This prevents the weight of larger core bits from slowly extending the cylinder. If the counterbalance valve is not properly adjusted it may try to lock the cylinder during normal operation, resulting in a rapid on/off cycle as the cylinder extends. If this occurs, screw out (clockwise) the adjustment on the bottom of the counterbalance valve until a smooth cylinder motion is achieved. This adjustment is factory set and should not normally need attention.
Figure 16: Counterbalance Adjustment
Raising and Lowering the Drill
The DRILL DOWN, DRILL UP, and TURBO switches are intermittent and must be held to operate. Holding UP or DOWN and TURBO will raise and lower the drill more rapidly for initial positioning or quickly pulling a bit out of a hole. These switches will not work when in the AUTO DRILL mode.
Raising and Lowering the Frame and Mast
To establish a more solid base, the pneumatic tires are raised off the ground. This same action places the vacuum base firmly on the ground. Electric cylinders at the front and rear of the machine are controlled by intermittent switches at the front control panel (Figure 3). The frame should be raised until the front and rear tires just clear or barely touch the ground. Independently adjusting the front or rear control allows slight leveling of the machine.
WARNING DO NOT exceed the core bit’s
maximum recommended speed when drilling.
DO NOT use damaged core bits when drilling to avoid harming yourself, others, or the machine.
16
Diamond Core Bits
Using the proper core bit (size and type) preserves the bit and improves drilling and operator efficiency, resulting in lower costs. Refer to www.diamondproducts.com for additional drilling and core bit information.
Inspecting the Core Bit
Inspect each core bit prior to installation and discard all damaged bits. Inspect all core bits for:
Cracks, nicks, and dents on barrel Darkness and/or discoloration near edge of bit Uneven wear Missing segments Bent segments Segment cracks
Core Bit Speeds
Refer to the chart on the machine for the recommended core bit speeds when drilling. DO NOT exceed the maximum recommended drilling speed.
Installing a Core Bit
WARNING Be extremely careful when
installing a core bit by hand with the spindle shaft rotating. Avoid entanglement!
Failure to properly secure the core bit to the spindle shaft may cause the bit to loosen or fall off the machine.
CAUTION Wear gloves and be alert to the surrounding
environment when handling core bits. Install the counterweight at the rear of the unit
when using core bits 16” or larger to prevent front-end tipping.
1. Select the correct core bit size and type for the
drilling task. 2. Raise the spindle shaft to provide room to install the
core bit. 3. For smaller core bits: Hold the bit with both hands
and screw it onto the spindle shaft until it bottoms out on the shaft. Make sure the bit is secure (the bit will tighten further once it enters the concrete).
4. For larger core bits:
a) Place the bit under the spindle shaft and align it with the shaft threads.
b) Start the engine. c) Set the Drill Rpm very slow. d) Set the Cyl Speed knob to a very slow speed. e) Press the Drill Down button to slowly lower the
spindle shaft until the threads are engaged with the hub. CAUTION: Proper hub and shaft alignment is critical to avoid cross threading. Stop immediately and readjust the bit if the shaft and hub are not aligned when installing the bit. When aligned, the shaft will screw itself into the hub and lift the bit off the ground. If required, apply light resistance to the bit to prevent spinning, which will allow the shaft to screw itself completely into the bit.
f) Set drill RPM to zero. 5. Raise the core bit to provide clearance between the
bit and the ground.
Figure 20: Core Bit Attached
Removing a Core Bit
CAUTION Move all body parts away from the
core bit when releasing the bit from the spindle shaft.
1. Lower the core bit very close to the ground. 2. Grasp the flats near the top of the spindle using the
wrench provided. Hold the wrench in place to stabilize the spindle shaft and use another appropriate tool to grasp the core bit hub.
3. Turn the tool clockwise, as viewed from above, to loosen the core bit.
17
4. When the bit is near the end of the threads. A. Remove smaller bits by hand. B. Allow larger bits to release and fall to the ground. Keep the bit close to the ground to minimize impact and help prevent segment damage. Dropping the bit onto wood or other soft surfaces will further reduce impact.
WARNING Lowering the bit too quickly into the
concrete surface can cause bit breakage, resulting in serious injuries and/or death.
Use extreme caution when drilling through floors. Another trained worker must clear the surrounding area on the lower floor prior to drilling in case the core falls to the lower floor.
Helpful Hints Prior to Drilling
Keep the following in mind for better efficiency while drilling:
Avoid drilling excessively deep to preserve the core bit and reduce costs.
For proper vacuum, make sure the drilling surface is clean and solid (no cracks, dents, etc.). Wetting the surface can help the vacuum seal.
Use a proper water flow to prevent damaged and stuck bits. Using too much water when drilling will make the slurry look clear. Not using enough water will make the slurry look thick and pasty.
Tasks Prior to Drilling
Complete the following tasks prior to drilling: Clearly mark the drilling area. Be sure the work area does not contain any buried
electrical, gas, water or other utility lines.
Drilling a Hole
1. Position the machine and core bit. 2. Move the function switch to Drill. 3. Lower the front mast and rear legs. All tires should
just clear or barely touch the ground. 4. Turn on the Vacuum switch and close the vacuum
valve. Check the vacuum gauge for pressure; stop to determine the problem if vacuum fails. Skip this step if the vacuum cannot be used when drilling.
5. Set the drill motor to high speed for bits up to 10” and low speed for bits larger than 10”.
6. Adjust the Drill Rpm based on the bit size. Refer to the chart on the machine for the recommended core bit speeds. DO NOT exceed the maximum recommended RPM.
7. Turn on the Water switch. 8. Open the water valve and adjust the water flow
valve to increase or decrease the water flow. 9. Use the Drill Down button and Turbo to lower the bit
close to the ground. Using only the Drill Down button, gently jog the bit to start the hole. Once ground contact is made, release the Drill Down button and turn the Auto Drill switch to On/Drill. The bit will continue drilling until the cylinder fully extends or until Auto Drill is turned off.
10. At the required depth, turn off the Auto Drill switch. 11. Press the Drill Up button to raise the bit out of the
hole. Pressing the Turbo and Drill Up buttons together will raise the bit quickly.
12. Set RPM to zero. 13. Turn off the water valve and Water switch. 14. If used, turn off the Vacuum switch and open the
vacuum valve to release the vacuum. 15. Lower all tires to the ground. Raise the mast and
rear legs fully up for maximum ground clearance. 16. Move the function switch to Start/Drive.
Continuing a Partial-Hole
1. Inspect the drill hole and remove, if possible, items that may cause the bit to stick (lost core bit segments, broken concrete).
2. Carefully align the bit with the existing hole and slowly lower the spinning bit back into the hole.
3. Finish drilling the hole following the directions directly above.
Stuck Cores
Removing a Stuck Core
1. Remove the bit from the machine. 2. Move the bit away from the work area. 3. Lay the bit on the ground. 4. Option 1:
a) Place a metal spike through the hub and drive the core out of the bit.
b) Inspect the bit for damages and clean or replace as necessary.
5. Option 2: a) Thread a piece of threaded rod (1-1/4-7) through
the hub until it contacts the concrete. b) Place two hex nuts on the rod end and lock
them against each other.
18
c) Holding the bit in place, grasp both nuts with a wrench and screw the rod into the bit to drive the core out.
d) Inspect the bit for damages and clean or replace as necessary.
DO NOT hammer on the bit! This will dent the tube, which can result in additional problems and increased hang-ups.
Stuck Bits
A bit can become stuck for several reasons: An insufficient water supply allows slurry to
accumulate, causing the drill to seize. Pushing the drill down too hard can cause the
machine’s frame to shift slightly (more susceptible when not using the vacuum).
If drilling completely through a slab, segments may catch at the bottom edge of the hole when raising the bit.
Partially cutting through a piece of rebar with just the outer edge of the bit (mooning) can deflect the bit, causing it to jam. Slowly cutting through rebar or hard spots can reduce this effect.
Removing a Stuck Bit
1. Turn off the Auto Drill switch. Press the Drill Up or Drill Down button and Turbo to attempt freeing the bit. It is best to keep the bit spinning if possible. If the bit is not spinning, turn the Drill Rpm cartridge on and off to try and get the bit to spin (system pressure will go to maximum as it tries to spin the bit). Continue with step 2 if this attempt fails.
2. Determine if the bit is still centered in the hole. If the bit has shifted toward the rear of the hole, slightly extend the rear legs (raise tires) to attempt to realign the bit. If the bit has shifted toward the front of the hole, retract the rear legs slightly (lower tires) to attempt to realign the bit. Use the Drill Up and Drill Down button while slightly raising and lowering the rear legs or front mast in an attempt to find the break-free position. Continue with step 3 if this attempt fails.
3. If steps 1 and 2 fail, the UDM must be disconnected from the bit, moved out of the way, and the bit extracted manually.
4. Turn the Drill Rpm cartridge to off. 5. Move the function switch to Start/Drive. 6. Turn off the engine. 7. Grasp the flats near the top of the spindle using the
wrench provided and turn the spindle counterclockwise, as viewed from above. This will disconnect the spindle shaft from the bit (about 10 turns are required).
8. Move the machine away from the bit. It may be necessary to raise the drill motor for clearance.
9. Insert a piece of threaded rod (1-1/4-7) through the hub until it contacts the concrete.
10. Place two hex nuts on the rod end and lock them against each other.
11. Grasp both nuts using a wrench and turn to push the rod against the concrete. This will pull the bit out of the concrete.
12. Inspect the bit for damages and clean or replace as necessary.
19

Remove the core bit to reduce residual pressure in the cylinder circuit prior to servicing the machine.
Inspect the hydraulic hoses and fittings daily for leaks. Replace damaged components immediately. Changing the Hydraulic Oil
An oil analysis program is recommended to determine the oil’s condition and when to change it. If the oil is kept
clean, dry, and is operated at moderate temperatures it may last for several years. With no analysis program, changing the oil every 200 hours is recommended. 1. Place an oil drain tray under the hydraulic tank’s
drain plug. 2. Remove the drain plug and drain the oil from the
tank. Replace the plug when completely drained. Dispose of the used oil according to city, state, and federal regulations.
3. Fill the tank to the sight port. DO NOT overfill as oil expands when hot. Use a high quality, petroleum based hydraulic oil with the following properties:
a) Anti-wear b) Low foaming c) Rust and oxidation inhibitors d) Wide temperature range e) Fluid viscosity: 8-1,000 Centistokes (52-4,600
SUS). Note: The machine is shipped with an ISO 46 viscosity grade (8 Cs/52 SUS @ 212°F/100°C and 46 Cs/210 SUS @ 104°F/40°C).
4. Replace the cap.

WARNING Turn off the engine prior to servicing
the belts.
CAUTION Always let the belts cool down prior to
servicing them.
Inspect the belt daily for fraying, stress cracks, and/or breakage and replace immediately when damaged. DO NOT exceed the manufacturer’s belt tension settings when tensioning belts. Note: Over-tensioning the belt
22
may damage the engine crankshaft. Under-tensioning the belt may cause slippage, shorter belt life, and poor generator performance.
Figure 25: Engine to Generator Belt
Tensioning the Belt
1. Test the belt tension. Refer to Appendix C. If adjustments are necessary, continue with step 2.
2. Loosen the nuts on the four screws (under the frame) securing the generator to the frame.
3. Turn the belt adjustment shaft nut clockwise to tighten the belt. Retest the tension and readjust the nut as necessary to reach the required tension setting. DO NOT exceed the manufacturer’s setting.
Figure 26: Belt Adjustment Shaft and Nut
4. Retighten the four nuts (under the frame) to secure
the generator.
Replacing the Belt
The pump must be removed and the pump mount loosened to access the sheave on the engine shaft. It is not necessary to remove the hoses from the pump. The best way to remove the old belt is to simply cut it and pull it out. Otherwise, follow the steps below.
1. Loosen the nut on the four screws (under the frame)
securing the generator to the frame. 2. Loosen the nut on the belt adjustment shaft. DO
NOT remove the nut. 3. Slide the generator toward the engine to loosen the
belt. 4. Remove the belt from the generator sheave. 5. Remove the two screws securing the hydraulic pump
to the pump mount. Pull the pump out and set aside. There is no need to remove hoses from the hydraulic pump.
6. Remove three of the four screws securing the pump mount to the engine. The fourth must be loosened.
7. With pump mount loose, guide belt around sheave and coupler and pull out through the pump end.
8. Insert loop of new belt through rear opening and out the side of pump toward the generator. Guide belt around the coupler and into position on the engine sheave.
9. Reattach the pump mount to the engine. 10. Reinstall the hydraulic pump, aligning it with the
coupling and pump mount. 11. Loop and align the belt around the generator
sheave. 12. Slide the generator toward the side of the machine
to tension the belt. 13. Turn the belt adjustment shaft nut clockwise to
tighten the belt. Test the belt tension and readjust the nut as necessary to reach the required setting. (Appendix C). DO NOT exceed the manufacturer’s recommendation.
14. Retighten the four nuts (under the frame) to secure the generator.
15. If required, the belt alignment can be adjusted by loosening the sheave on the generator shaft and repositioning it.
Roller Carriage
The roller carriage moves the core bit up and down the mast. The carriage must be snug on the mast to support the bit and prevent unwanted motion. A consistent small gap should be visible between the mast and the top inner edges of the carriage. If a twisting or fore and aft rocking motion is visible while drilling, the carriage has become loose and required adjustment. This same twisting motion can be checked by gently pushing and pulling sideways on the pillowblock. The fore and aft rocking motion can be simulated by manually lifting up on the pillowblock. The normal weight of the pillowblock, drill motor and bit tends to tip the carriage forward slightly.
23
If only the rocking motion is visible, only the rollers at the rear of the carriage need adjustment. If the twisting motion is visible, both the side shims and rollers may need adjustment.
Figure 27: Roller Carriage, side shims & rear rollers.
The shims and rollers may be adjusted on a fully assembled machine. However, it is best to detach the carriage from the spacer block so it can be manually moved up and down the mast. If the carriage falls down the mast by its own weight it is too loose. If the carriage cannot be moved by moderate hand force, it is too tight.
Disconnecting the Carriage
1. Place a reliable support under the spacer/pillow block assembly.
2. Support the roller carriage. NOTE: It may be easiest to fully extend the hydraulic
cylinder and thus place the pillowblock and carriage at or near ground level.
3. Remove the four bolts between the spacer and
carriage. The carriage is now free to move independently.
4. Roll the carriage up and down the mast to test its movement. The carriage should move easily with light force applied and should not fall to the ground. Adjust the shims and rear rollers as necessary.
Adjusting the Shims
1. Remove the four side roller housings. 2. Remove an equal number of shims from all side
roller housings to tighten the carriage. Add an equal number of shims to all side roller housings to loosen the carriage.
3. Replace the side roller housings and secure. 4. Check the carriage motion and repeat if required.
Adjusting the Rear Rollers on a disconnected carriage:
1. Loosen the setscrews at both ends of the upper and lower rollers.
2. Simultaneously turn both hex heads on one roller until you feel the roller contact the mast. The dimples on the hex heads should remain aligned.
3. Tighten the two setscrews on the adjusted roller. 4. Repeat steps 2–3 to adjust the second roller. 5. Check the carriage motion and repeat if required.
To Connect the Carriage:
1. Realign the roller carriage with the spacer/pillowblock assembly.
2. Insert and tighten the four bolts removed previously..
Adjusting the Rear Rollers on a connected carriage:
1. Lift up on the pillowblock to balance the normal weight of the pump, pillowblock and bit.
2. Proceed with steps 1 thru 5 above.
Replacing the Rollers
Over time, the rollers can wear to the point that adjustment is no longer possible. To replace the rollers, the cylinder assembly must be removed from the top of the mast and the carriage must be slid completely off the mast. 1. Disconnect the carriage following the instructions in
the previous section. 2. Remove the clevis pin from the cylinder rod end. 3. Remove the large bolt at the top of the mast. 4. The cylinder assembly and guide block can now
slide up and off the guide rail. Be prepared to safely support the cylinder. There is no need to remove the hoses.
5. Slide the carriage off the mast. 6. REAR ROLLERS: loosen the four setscrews. The
hex head adjusters will now pull out and release the rollers. Install new rollers and reassemble.
7. SIDE ROLLERS: remove the four bolts in each of the side roller housings and pull out the assemblies. Drive out the pin from each housing to release the roller. Install new rollers and reassemble.
8. FRONT ROLLERS: remove the upper cover plate and loosen the setscrews on the upper and lower shafts (no cover plate on lower roller). Drive out the shafts to release the rollers. Install new rollers and reassemble.
9. Place the carriage onto the mast and adjust the shims and rear rollers for proper movement.
24
10. Carefully slide the cylinder assembly and guide block onto the guide rail and mast.
11. Replace and tighten the large bolt at the top of the cylinder bracket/mast.
12. Install the clevis pin through the cylinder rod end and spacer/pillow block assembly.
13. Reconnect the carriage following the instructions below.
Connecting the Carriage
1. Realign the roller carriage with the spacer/pillow block assembly.
2. Insert and tighten the four bolts previously removed.
