NOTE: If an indicator light does not turn on, see
Troubleshooting or contact a Generac Mobile Products
Authorized Service Dealer.
NOTE: The lights require a warm up period of 5-15
minutes before they reach full output. If the lights are shut
down, they require a cool down period of approximately
ten minutes before they can be switched on again.
NOTE: The light tower uses four 1000W or 1050W
bulbs. When checking or replacing the bulbs, wipe them
with a clean cloth to avoid leaving any grease, oil residue
or fingerprints on the glass. Any residue can create a hot
spot on the bulb, causing premature bulb failure.
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.

Auxiliary Outlets

See Figure 3-9. The receptacle panel is equipped with
six receptacles for running accessories or tools from the
generator. Power is supplied to the receptacles any time
the engine is running and the main circuit breaker is
switched to the ON (I) position. The standard receptacle
panel is equipped with two of each of the following
receptacles:
(A) 240V/30A Twist-lock
(B) 120V/20A CGFI
(C) 240V/50A Twist-lock
Should the main breaker trip, remove some of the load to
the receptacles before turning them back on.

Each receptacle has an individual circuit breaker which is
located behind the receptacle panel. The breakers are
labeled with the corresponding amperage for the
receptacle they protect.
With all of the lights off, the full generator output may be
used with the receptacles.
NOTE: To ensure proper grounding, anytime the
generator is providing power to any equipment or load
panels that do not have a grounded plug, a ground wire
MUST BE added between the equipment and the
grounding stud on the receptacle panel per the National
Electrical Code (NEC), state, and local regulations.

Voltage Regulation

Units are equipped with an electronic voltage regulator.
The voltage regulator controls the output of the generator
by regulating the current into the exciter field. The voltage
regulator is adjusted before shipment from the factory.
Contact Generac Mobile Products LLC for additional
information before attempting to adjust the voltage
regulator.

Wet Stacking

The unit is powered by a diesel engine. Diesel engines are
susceptible to wet stacking if lightly loaded. Wet stacking
occurs when an engine is run at less than 30% of its full
load capacity, causing unburned fuel to accumulate in the
exhaust system. Wet stacking can be detected by contin-
uous black exhaust when the unit is under a constant load.
It can also cause fouling of injectors and buildup on engine
valves. Diesel engines operate properly when applied
loads are between 30% and 100% capacity. Appropriate
generator sizing is determined by the anticipated load. If
the unit is in a wet stack condition, load the unit heavily for
five hours or until the exhaust is clear.
