SHUTTING DOWN THE UNIT
Check with personnel using power supplied by the unit and let them know the power is going to be turned off. Make
sure the power shut down will not create any hazards by accidentally turning off equipment that needs to be kept on
(pumps, compressors, lights, etc.).
When you have finished using the unit, proceed with shut down as follows:
1. Remove any loads from the receptacles.
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.
Note: For extended storage time, disconnect the battery. For extended storage requirements, refer to the engine
operator’s manual.
LOWERING THE MAST
ELECTRICALLY LOWERING THE MAST
1. Shut down the lights and engine. Allow the lights to cool 10-15 minutes before lowering the mast.
2. If the trailer is going to be moved, it is recommended that the mast is turned so the lights face toward the back
of the unit. To rotate the mast:
A. Loosen the mast rotation knob.
B. Rotate the mast until the white arrows are aligned and the metal stop tabs are touching. The winch and lights
should be facing toward the back of the unit.
C. Tighten the mast rotation knob.
3. Press and hold the winch control toggle switch downward to collapse the mast to its lowest position. Ensure the
electrical cord does not get caught in, or pinched by, the mast while it is being lowered.
CAUTION
STOP IMMEDIATELY if the mast hangs up, or the winch cable begins to develop slack.
Excess slack in the cable could cause the mast to collapse, which could result in personal
injury or equipment damage. Contact an authorized service center.
Note: If the generator is not operational, and the batteries do not have enough power to lower the mast, it may be
necessary to lower the mast manually.
Note: Magnum Power Products LLC strongly recommends that the lights be removed from the mast and stowed for
transportation. Refer to ““Removing the Lights for Transportation” on page 21.
