Light Operation
WARNING
Burn hazard. Never operate lights with a
damaged or missing lens cover. Lamps are
hot and pressurized while in use. Unprotected
lamps can shatter, causing severe injury.
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.
See
Figure
3-5. The lights are turned on and off using
the Power Zone–DLA. To view the light screen, press the
↑ button three times from the Home screen.
NOTE: The lights can only be turned ON and OFF while
the unit is running in MANUAL mode. They operate
automatically in AUTO mode.
1. Once the engine is up to temperature and running
smoothly, switch the main circuit breaker ON (I).
2. To turn the light(s) ON, press the Select () button.
To turn the light(s) OFF, press the Select ()
button.

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
10 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.
Engine Derating
All units are subject to derating for altitude and
(000277)
temperature. Derating reduces the available power for
operating tools and accessories connected to the
receptacles. Typical reductions in performance are 2-4%
for every 1000 ft (305 m) of elevation and 1% per 10ºF
(5.6ºC) increase in ambient air temperature over 72ºF
(22ºC).

Wet Stacking
The unit is powered by a diesel engine. Diesel engines
are subject 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 continuous 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.
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
regulator
potentiometers that may be adjusted for voltage, stability
and voltage roll-off (U/F). The voltage regulator is
adjusted before shipment from the factory. Contact
Generac Power Products LLC for additional information
before attempting to adjust the voltage regulator.
Customer Convenience Outlets
See

convenience outlets for powering accessories or tools
from the generator. Power is supplied to the outlets any
