ALWAYS observe the tower while raising and lowering the mast.
NEVER raise the mast or operate the Light Tower in high winds.
NEVER raise the mast while the engine is running.
HIGH VOLTAGE! DO NOT use Light Tower if insulation on electrical
cord is cut or worn through. Repair or replace cord before using. Bare
wires in contact with the metal frame of the trailer or the Light Tower
can cause electrocution.
DO NOT position the Light Tower under electrical power lines.
NEVER allow anyone to stand near the rear of the unit while raising the
mast.
The Light Tower includes two separate winches. One for lifting the
mast to the vertical position, the other for raising the tower.
Check the winch cables (n) for wear or damage, and make sure they
are resting properly in the pulleys. Do not use the Light Tower if either
winch cable is damaged.
Remove the cradle locking pin (j) from the cradle.
Check the operation of the tongue-mounted winch (o). Turn the vertical
rotary switch (v) on the control panel to the up position. Do not attempt
to raise the mast if the winch is damaged or not operating properly.
CAUTION: Continuous running of the winch in excess of 4 minutes will
damage the winch motor.
Note: It is normal for smoke to be produced during the first few
operations of a new power winch.
Hold the switch in the up position and raise the mast to the vertical
position until the vertical mast locking pin (p) locks the mast in place.
Be certain the vertical mast locking pin is fully engaged in the locking
position before raising the tower.
NEVER pull the vertical mast locking pin (p) while the tower is
raised! Releasing the vertical mast locking pin while tower is raised
may cause the tower to fall or the machine to tip over.
