18 Owner’s Manual for Mobile Light Tower
Operation
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 shutdown will not create any
hazards by accidentally turning off equipment that needs
to remain running (pumps, compressors, lights, etc.).
1. Remove all loads from the outlets.
2. See
Figure 3-10 . Switch the individual circuit
breakers for each light OFF (O).
3. Switch the main circuit breaker OFF (O).
4. Turn Control Power switch to OFF (O) position.
NOTE: For extended storage time, disconnect the
battery. For extended storage requirements, refer to the
engine operator’s manual.
Figure 3-10. Shutting Down the Unit
Lowering Mast
1. Shut down the lights and engine. See Shutting
Down the Unit .
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.
3. Turn upper mast winch handle counterclockwise to
collapse mast to its lowest position. Verify the
coiled electrical cord does not get caught in, or
pinched by, the mast while it is being lowered.
IMPORTANT NOTE: Contact a GMASD immediately
if the mast hangs up or the winch cable develops
slack.
4. Release the mast lock by pulling the safety pin on
the mast lock and pulling the lock bar free. Turn the
handle 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.
NOTE: Generac Mobile strongly recommends that the
lights be removed from the mast and stowed for
transportation.
See Removing Lights for
Transportation .
Removing Lights for
Transportation
1. See Figure 3-11 . On units equipped with quick
disconnect fittings for the lights, disconnect the
power cords from the junction box at the top of the
mast.
2. Replace the dust caps on the junction box. On
other units, remove the junction box cover on the
top of the mast and disconnect
ONLY the mast
light wires from the terminal blocks.
3. To release the wires from the terminal blocks, flip
the locking levers down and pull out the
appropriate wires.
4. Remove the lights by removing the nyloc nut that
holds the light fixture bracket to the cross tube.
5. Attach the lights to the storage brackets (if
equipped) located on the mast tube on either side
of the central lifting eye.
NOTE: When installing the lights, verify the star washer
is in place between the trunnion and nylock nut before
tightening.

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.
WARNING
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.
