Operation

AUTOMATIC SHUTDOWN

This unit is equipped with a low oil pressure and high coolant temperature automatic shutdown system. This system
will automatically shut off the fuel supply to stop the engine if oil pressure drops too low or the engine exceeds normal
operating temperature. Return the Control Power switch to the OFF position to reset the unit after you have determined
the cause of the shutdown.

LOWERING THE MAST - MANUAL

1. Shut down the lights and engine, refer to
minutes before lowering the mast.
2. If the unit is going to be moved, it is recommended that the mast is turned so the lights face the rear 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.
c. Tighten the mast rotation knob.
Note: For transportation, Generac Mobile Products strongly recommends the lights be removed from the mast and
stowed. Refer to "Removing the Lights for Transportation" on page
3. Turn the upper mast winch handle counterclockwise 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.
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.
4. Release the mast lock by pulling the safety pin on the mast lock and pulling the lock bar free. Turn the han-
dle of the lower mast winch counterclockwise until the mast rests in the transport cradle.
Note: If the mast lock bar does not pull free, activate the lower winch slightly to relieve pressure on the mast bar.
5. After the mast is completely down, insert the mast cradle locking pin and secure it with the safety pin.
