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 strongly recommends that the
lights be removed from the mast and stowed for

Towing the Unit

Once the engine is shut down and the mast and lights are
properly stowed, follow these steps to prepare the unit for
towing.
1. Raise the rear jack completely and release the
locking pin to rotate it up into the travel position.
Verify the locking pin snaps into place.
2. Raise the outrigger jacks completely and release
the jack locking pin to swing the jacks up into the
travel position. Verify the locking pins snap into
place. Release the outrigger locking pins and slide
the outriggers into the trailer frame until the locking
pins snap into place.
3. Use the tongue jack to raise or lower the trailer
onto the hitch of the towing vehicle. Lock the hitch
coupling and attach the safety chains or cables to
the vehicle. Remove the jack locking pin and rotate
the jack into the travel position. Replace the locking
pin.
NOTE: A film of grease on the coupler will extend
coupler life and eliminate squeaking. Wipe the coupler
clean and apply fresh grease each time the unit is towed.
4. To ensure proper operation of the jacks, lubricate
the grease fittings located on the leveling jacks.
