SHUTTING DOWN
When you have finished using the light tower proceed with shut down as follows:
1. Remove any loads from the auxiliary outlets.
2. Switch the individual circuit breakers for each light
to the OFF “O” position.
3. Switch the main circuit breaker to the OFF “O”
position.
4. Turn the ENGINE START SWITCH to the OFF position.
LOWERING THE TOWER
1. Shut down the lights and engine. Allow the lights to cool 10-15 minutes before lowering the tower.
2. Turn the upper mast winch handle to collapse the tower to its lowest position. Make sure the electrical cord
returns to the storage tube properly.
WARNING
If the mast hangs up or the winch cable begins to develop slack, STOP IMMEDIATELY!
Excess slack in the cable could cause the mast to collapse should it free up without
warning. Contact an authorized service center.
3. Loosen the mast rotation knob and rotate the tower so the mast mounted winches face the front of the unit. The
white alignment arrow points should line up on the mast sections and the metal stop tabs should be touching.
Tighten the mast rotation knob.
4. Release the mast lock by pulling the safety pin on the mast lock and pulling the lock free. Turn the handle of the
lower mast winch until the mast spring begins to pivot the tower down. Release the mast lock and continue to
lower the tower until it rests in the cradle.
Note: If the mast lock does not pull free, operate lower winch slightly
to relieve pressure on the mast lock.
5. After the mast is completely down, insert the cradle lock pin and secure it with the safety pin.
6. Position lights to aim at the ground. If the trailer is going to be moved, Magnum Products LLC strongly recommends
that the lights be removed from the mast and stowed for transportation. See REMOVING THE LIGHTS FOR
TRANSPORTATION section on page 19.
LOWERING THE TOWER EQUIPPED WITH THE OPTIONAL ELECTRIC WINCH
1. Shut down the lights and engine. Allow the lights to cool 10-15 minutes before lowering the tower.
2. Loosen the mast rotation knob and rotate the tower so the mast mounted winches face the front of the unit. The
white alignment arrow points should line up on the mast sections and the metal stop tabs should be touching.
Tighten the mast rotation knob.
3. Press and hold the upper winch control toggle switch downward to collapse the mast to its lowest level. Make
sure the coiled electrical cord on the top sections of the mast does not get tangled on the mast sections. Note:
Some electric winch models are equipped with an anti-backlash safety limit switch. This switch will disconnect
power to the winch if excess cable slack is detected, preventing accidental lowering of the tower. If, for any
reason, the cable begins to develop slack or any of the tower sections get stuck,
STOP IMMEDIATELY and
contact an authorized service center.
