running (pumps, compressors, lights, etc.).
1. Remove all loads from the outlets.

Lowering the Mast

WARNING
Burn hazard. Lamps become extremely hot
while in use. Allow 10–15 minutes for cooling
before handling or lowering mast. Touching a
hot lens or fixture can cause severe burns.
1. Shut down the lights and engine. See
Down the Unit.
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. Verify the electrical cord does not get
caught in, or pinched by, the mast while it is being
lowered.

Personal Injury. Stop immediately if the mast hangs
up or the winch cable develops slack. Excess slack
could cause the mast to collapse, resulting in personal
injury or equipment damage.
IMPORTANT NOTE: Contact a GMASD immediately if
the mast hangs up or the winch cable develops slack.
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: Generac Mobile recommends lights be removed
from the mast and stowed for transportation.
