2. You have purchased a very high quality piece of equipment that shouldprovide years of useful life. Following the instructions below and themanufacturers generator operating instructions should provide yearsof safe and reliable service.UNLOADING THE TOWER/LIFTING THE TRAILERWhen unloading the tower from the trailer, make sure lifting equipment andrigging is sufficient. Note that the weight of the unit with fuel is 14,000 lbs./6350kg. Attach rigging to the points marked sling here only. Failure to do so couldcause severe damage to the unit and injury/death to bystanders.ATTACHING LIGHT FIXTURESThe 16 light fixtures will be shipped in a separate container. Carefully unwrap andwith the use of a stable platform or ladder, bolt the fixtures securely to the mast.Note that they can be mounted in various directions, forward or rear-facing, tolight different areas. Tighten the bolts carefully and tightly, placing an includedwasher between the nut and the fixture.2 3. Next, tighten the vertical adjustment lever on each fixture by pulling down on thelever on each side of the fixture until snug.The tower may be towed with the fixtures attached for short distances on smoothroads. Bumpier roads may cause damage to the fixtures and the bulbs. Make sure 3-prong wires from lights are firmly plugged into junction boxes onthe light mast.3 4. OPERATING THE UNITInspect all electrical connections and wires and cables for damage that may havebeen caused in transit. Do not operate the unit if damage to wiring or electricalcomponents is detected. Repairs should only be attempted by qualified electricalpersonnel.Leveling- Make sure the unit is on hard, level ground with the wheels chockedfrom the front and the rear. Extend outriggers fully, which will be eleven feet/3.5meters. The pins for the middle section of the outrigger will be stowed in theforward tool compartment at the front of the trailer. Replace pins in bothlocations and lower pad with crank handle until pads are firmly on the ground. 4 5. When all six pads have been lowered, make adjustments to each according to thetwo horizontal leveling indicators mounted near the mast. Insure the trailer issecurely level. DANGER- FAILING TO LEVEL UNIT CORRECTLY COULD CAUSETIPPAGE RESULTING IN DEATH!Always disconnect trailer from towing vehicle before use. Remove mast travelingpin, which secures the mast in the horizontal position, located above generator.Remove mast locking pin at base of mast. . See pin locations in picture, below.CHOCK TRAILER WHEELS! 5 6. 6 7. COLD WEATHER- Low-temp gear oil is available for the winch. Low temp (-60F)Shell Tellus S4VX32 or Petro Canada Hydrex Arctic 15 hydraulic oil is available forthe hydraulic pump. If arctic operation is desired, insure unit was shipped withlow temp gear oil in the winch and low temp hydraulic oil in the hydraulic pump.Open Louvers on Ballast Box- Louvers are designed to keep ice and mud fromentering vents in ballast box. Close units during transport but open during use toventilate ballast box. 7 8. Start generator according to manufacturers instructions, attached. Do notoperate lights until boom is at desired height.Never operate generator unless in a well ventilatedoutdoor space as carbon monoxide death will occur. Carbon Monoxide iscolorless and odorless. 8 9. Generator will shut off after 10 seconds if fuel level is below 15%. See engine self-diagnostics on generator control panel.The generator selector switch should be pre-set to 240/120v 1-PhaseTurn main switch on generator panel to on.MAST OPERATIONPlug 110 v cord from hydraulic pump into 110 outlet on generator control paneland turn 20 amp outlet breaker to on position. This will allow the hydraulic pumpto operate. You should hear the pump activate when the power is turned on tothe receptacle. The other breakers are for use of the 220 or other 110 outlet for9 10. other applications such as tools, if desired. UNPLUG HYDRAULIC UNIT PUMP ORTURN OFF BREAKER WHEN NOT OPERATING HYDRAULICS TO PREVENTUNECESSARY USAGE OF HYDRAULIC MOTORGently pull closest hydraulic lever (Mast Tilting Lever) towards the front of thetrailer to move mast from travelling position into its vertical position. If levers willnot activate the winch, the cap next to the levers may be removed to adjust thelever sensitivity with an allen wrench. Always adjust lever sensitivity to lowestpressure that will operate pump. When mast is vertical, replace mast locking pin.Danger- Failure to replace mast locking pin could cause injury and damage to themachine! Never try to move the tower unless mast is in horizontal and securedposition. 10 11. Once mast is vertical, the top of the lights will be 25 feet or 7.6 meters off theground. This may be sufficient for certain lighting applications or when higherwind conditions are present.To Telescope the Mast- Again, make sure mast locking pin is in place, and checkcables and electric wires for fraying or signs of wear.If any fraying or signs of wear are detected, discontinue use and contact aqualified repairman. Make sure unit is leveled and all outriggers are down,including front jack stand. Lowering the front jack stand will result in smootherwinch operation, especially on descent.Pull handle farthest from operator towards the front of the trailer. This willtighten the two cables and pull the three boom sections upward. Raise to desiredheight. Stop operation if frayed cables are observed or in the event of irregular11 12. pump operation. Do not raise boom past red 55 feet indicator when indicatorshows on mast. That means the boom is fully extended. Attempting to overextend the boom can result in serious unit damage and injury.Note: The hydraulic pressure is set by the adjustment screw by the levers andby the gold safety valves on the boom tilting piston, to intentionally only allowthe minimum pressure required to activate the piston and winch. To fully raisethe winch to 55 feet (16.8 meters) should take 5-8 minutes. If the levers do notactivate the piston and/or the winch, or the boom will not telescope to the 55Feet mark, the pump pressure adjustments will have to be changed. Turn breaker for hydraulic pump off or unplug pump after unit is in operation to avoid wear on pump. Lower unit if windy or severe weather is forecast or if lightning is possible.TURNING ON LIGHTSThrow main disconnect switch to on. 12 13. Open glass cabinet door of ballast box to access 16 individual light switches.Turn on four circuits in sequence and wait until those four lights are fullyilluminated. Then turn on the next 4 and wait until lit, until all 16 lamps areilluminated or until desired number of lights are in use. Turning on more thanfour lights without waiting for them to fully illuminate will shut down the 13 14. generator on a safety override and the starting sequence will have to berepeated.LOWERING MASTTurn off individual lamp switches in glass cabinetPlug in hydraulic pump into 110 outlet in the generator cabinet and/or turnbreaker for the outlet back on. You should be able to hear the hydraulic pumpwhirring.Push lever farthest from operator towards rear of trailer to lower mast. The leveris adjusted to cause the winch to lower the mast very slowly. It should take 5minutes to fully lower the mast. If cable is frayed, discontinue use and contact aproperly credentialed repair technician.Mast is designed to be held in place by one of the two cables should one break.However, if one does break, discontinue use immediately, move personnel awayfrom trailer and contact a properly trained repair technician. 14 15. Mast fully lowered when all mast sections are retracted and cables on bothpulleys show slack.Mast should lower smoothly. If for some reason the mast hangs up, contact arepair technician. Do not continue to attempt to lower mast.When it is desired to stow the mast, such as when towing or in severe weather,and the mast is fully retracted, then and only then, remove the mast locking pin(see photo on page 9) near bottom of mast. Move hydraulic lever closest tooperator towards the rear of the trailer until boom is resting in the cradle. It willbe necessary to move the electric wiring out of the cradle before fully loweringto avoid damaging the cables.15 16. Do not attempt to continue to lower the mast once it is sitting in the cradle asdamage will occur. Replace mast travelling pin. 16 17. SHUTTING UNIT OFFTurn off main disconnect, let generator run 1 minute without a load and shutdown generator according to generator directions, attached. Never shut thegenerator down with a load as damage to generator and/or ballast box mayoccur.The metal halide floodlights require 5 minutes to reach full intensity and 15minutes to fully cool. WHEN REFUELING GENERATOR MAKE SURE UNIT ISOFF AND THE TWO FUEL VALVES TO AUXILLARY TANK ARE TURNEDOFF OR OVERFLOW WILL OCCURTOWINGAlways pull trailer with a proper vehicle at a very safe speed. Neverpull faster than 50 mph/80kph, much slower when towing down a hill.Never pull a trailer utilizing vehicle cruise control as that allows slackand swerving to occur, especially downhill. Towing vehicle must have apintle ring receiver and electric trailer break connector. Always useanti-telescoping cable to prevent boom from sliding out duringtransport.17 18. WIND INSTABILITY AND DANGER OF UNIT FALLING OVERThe following is a chart of when the unit becomes aerodynamically unstable. Thedata assumes the wind is coming from the most vulnerable direction, which iscalculated to be a side wind with all of the bulbs turned to face in that direction.The danger of flying debris from the light fixtures should also be considered inhigh winds and appropriate safety precautions should always be considered inlight of predicted or anticipated weather conditions. These precautions couldinclude: Lowering the mast to an appropriate height for the weather condition Stowing the mast in its travelling position 18 19. Removing the fixtures from the mast and stowing it to its travelling position. Never erecting mast in proximity of electric wiresTower Height in FeetToppling Wind Speed inmiles per hour55 Feet 70 mph45 Feet 90 mph35 Feet 100 mph25 Feet 120 mphDAILY INSPECTION Tires are inflated to manufacturers recommended pressure and lug bolts secure All trailer running light fixtures working and undamaged Dual safety chains securely attached to towing vehicle Check all wiring and breakers for damage Check all fluid levels: radiator, hydraulics, engine oils Check cables for evidence of fraying Make sure mast securing pin is properly installed Check outriggers are undamaged and in the correct position with all pins securing the jacks and outriggers.All Rights ReservedCopyright 2012 DMI Pipe Fabrication, LLC d/b/a DMI-LT 19
