INSPECTION/SETUP
MAIN CIRCUIT BREAKER
The generator is equipped with a 3-pole, 100-amp circuit
breaker to protect it from overload. Make sure that the circuit
breaker is in the OFF position prior to starting the engine.
LUBRICATION OIL
Fill the engine crankcase with lubricating oil through the
filler hole, but DO NOT overfill. Make sure the generator
is level and verify that the oil level is maintained between
the two notches (Figure 7) on the dipstick. See Table 9 for
proper selection of engine oil.

clean. If the oil is not clean, drain the oil by removing the
oil drain plug, and refill with the specified amount of oil as
outlined in the Perkins Engine Owner’s Manual. Oil should
be warm before draining.
Other types of motor oils may be substituted if they meet
the following requirements:

FUEL CHECK
Refilling the Fuel System
This generator has a fuel tank located in the sub base
assembly frame (Figure 3). ALWAYS fill the fuel tank with
clean fresh #2 diesel fuel. DO NOT fill the fuel tank beyond
its capacity.
Pay attention to the fuel tank capacity when replenishing
fuel. The fuel tank cap must be closed tightly after filling.
Handle fuel in a safe container. If the container does
not have a spout, use a funnel. Wipe up any spilled fuel
immediately.
Refueling Procedure:
DANGER
Fuel spillage on a hot engine can cause
a fire or explosion. If fuel spillage occurs,
wipe up the spilled fuel completely to
prevent fire hazards. NEVER smoke
around or near the generator.
CAUTION
ONLY properly trained personnel who have read
and understood this section should refill the fuel tank
system.
WARNING
Diesel fuel and its vapors are dangerous
to your health and the surrounding
environment. Avoid skin contact and/or
inhaling fumes.
CAUTION
ALWAYS make sure generator is on firm level ground
before refueling to prevent spilling and maximize the
amount of fuel that can be pumped into the tank.
