Circuit Breakers
To protect the generator from an overload, a 3-pole, 110 amp,
main circuit breaker is provided to protect the U,V, and W
Output Terminals from overload. In addition two single-pole,
20 amp GFCI circuit breakers are provided to protect the
GFCI receptacles from overload. Two 50 amp, 2-pole circuit
breakers have also been provided to protect the auxiliary
receptacles from overload. Make sure to switch ALL circuit
breakers to 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 31) on the dipstick. See Table 11 for proper
selection of engine oil.

When checking the engine oil, be sure to check if the oil is
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 Isuzu 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
DANGER - EXPLOSION/FIRE HAZARDS
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.
Refilling the Fuel System
CAUTION - REFUELING THE GENERATOR
ONLY properly trained personnel who have read and
understand this section should refill the fuel tank system.
Located at the bottom-front of the cabinet (Figure 32) is the
internal fuel tank. Some generators may be equipped with a
trailer mounted fuel tank (option). ALWAYS fill the either fuel
tank with clean and fresh #2 diesel fuel. DO NOT fill the fuel
tanks beyond their capacities.
Pay attention to the fuel tank capacity when replenishing
fuel. The fuel tank cap must be closed tightly after filling.
Handle fuel in a safety container. If the container does not
have a spout, use a funnel. Wipe up any spilled fuel
immediately.
