WORK SAFELY!STEP 2: deploy mast to vertical positionOnly a qualified service technician with proper trainingshould perform this installation. If you need assistancewith this installation, contact Multiquip for the location of itsnearest ASC. Follow all shop safety rules when performingthis installation.Refer to Figure 5.STEP 1: Secure light tower1. Make sure both outriggers are extended. To extend theoutriggers, pull the locking pin on the outrigger and holdwhile sliding out the outrigger assembly. See Figure 3.1. To release the mast from the mast cradle support, pullthe retaining pin out of the cradle lock/release pin. Pullthe cradle lock/release pin. This will unlock the mastfrom the horizontal position.2. Remove the mast lock/release pin before raising towerto the vertical position.3. To place the mast in the vertical position, turn thevertical mast winch hand lever clockwise until the mastis pointing upwards at 90 degrees.4. Once the mast is in the vertical position, insert themast lock/release pin to prevent the mast from falling.PULLOUTRIGGERTO EXTENDTO RELEASEOUTRIGGERPULL PINRETAININGPINROTATE JACKSTAND TO PLACEIN EPINOUTRIGGERJACK STANDFigure 3. Deploying Outriggers2. As soon as the pin clears the travel position hole,release it and continue sliding out the outrigger. Thepin must snap into the outrigger locking hole in theextended position.3. After extending all outriggers, rotate all trailer jackstands into the foot down position, then turn the crankhandle on the jackstands clockwise to lower it and levelthe light tower.4. Place chock blocks under each trailer wheel to preventrolling. See Figure ANDLECHOCKBLOCKSFigure 5. Deploy Mast to Vertical PositionFigure 4.

STEP 13: testing and reassemblyShutdown1. Reassemble the light tower in reverse order. Do notput the cabinet back on until testing is complete.1. If a load is attached to the generator of the light tower,remove the load.2. The main circuit breaker (25 amps) and 4 lamp circuitbreakers (10 amps each) are located on the uppercontrol panel (See Figure 26) . Each lamp has a 10amp circuit breaker.2. Set the four lamp circuit breakers on the control panelto the OFF position.3. Place the main circuit breaker (Figure 26) on the controlpanel to the ON position.MAINCIRCUITBREAKER240 VAC/30AMAINBREAKER120 VAC/15AGFCIBREAKERSenDEC0.0HOURSHOURS1/101/10LIGHT CUITBREAKERSFigure 26. Control Panel Circuit BreakersNOTICEYour control panel may be slightly different than thatshown in Figure 26.4. Set lamp circuit breaker #1 on the control panel to theON position.3. Place the MAIN circuit breaker on the control panel tothe OFF position.4. Wait a few seconds and observe that all four lampsare OFF.5. Let the engine idle for a few minutes with no load.6. Turn the ignition key to the OFF position. Store key ina safe location.7. Reassemble the cabinet.8. Lower light tower mast and place in stow position asoutlined in this manual.9. Place outriggers in tow position, and remove chockblocks.10. Store light tower in a clean, dry location out of the reachof children and unauthorized personnel.NOTICEIf servicing is required, allow lamps to cool for about15 minutes before removing lamps.Emergency Shutdown1. Turn the ignition key to the OFF position and turn allcircuit breakers to the OFF position.5. Wait a few minutes for the ballast to activate. Observethat lamp #1 is ON.6. Repeat steps 2 and 3 for lamps 2 through 4.7. If all the lamp circuit breakers are in the ON position(up), then all of the lights should be on.8. If any of the lamps are not on, refer to the troubleshootingsection in your operation manual.9. Run the light tower for 10 minutes to ensure that thegenerator is working properly.LT12 series light towers — generator conversion instructions p/n 49165 — Rev. #2 (11/01/13) — Page 9 of 10
