MANUAL WINCH MAST
The lighting tower assembly consists of a three-section telescoping mast which can be raised
and extended by operating the manual winch. This winch, mounted with the handle extending
at the back of the trailer flame, raises and lowers the mast from the horizontal towing position,
the vertical position, and the back. And the manual extends the telescopic sections.
Lock pin at lower right position and pull upper left pin out to raise or lower the three section
mast as necessary.
WARNING
Always check for overhead obstructions before raising and lowering mast. Avoid all overhead
electrical wires.
To prevent instability and help ensure safe operation, always provide proper ground support
before raising mast.
Before raising mast, visually inspect equipment for damage or wear .
NOTE: The latch locks the mast in the vertical position and disengages the sections allowing
the tower assembly to be rotated to position the lights.
TO LIFT THE MAST AND LIGHTS
Open side outrigger, rear hydraulic jack and front hydraulic jack to stabilize and level the
trailer.
NOTE: Hydraulics jacks should be placed only on firm ground.
WARNING
When open rear jack, watch to ensure you are clear of the mast before you stand up.
Inspect equipment for damage before operating. Allow adequate clearance around trailer for
tower and insure that no person are standing in front of or behind the machine when lowering.
TO LOWER MAST AND LIGHTS
1.
Turn off lights.
2.
Operate hand crank winch on tower counter-clockwise to lower the lights to the lowers
vertical position.
3.
Operate hand crank winch on side of trailer clockwise to take up any cable slack.
4.
Operate the hand crank on the side of the trailer counterclockwise to fold the mast down into
the towing position.
5.
Raise jacks and rear stand, retract outriggers and secure for towing.
NOTE: Sufficient load must be applied to the cable to overcome internal resistance and operate
the brake properly. Insufficient load will not turn the reel thus continual turning without sufficient
load will remove the winch handle from the shaft. After working, fold three section mast and
lock the pin to put mast horizontal level.
