Circuit Breakers

To protect the generator from an overload, a 3-pole, 175 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.Three 50 amp load 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 28) on the dipstick. See Table 11 for proper selection of engine oil.

Fuel Check

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.

Refilling the Fuel System

CAUTION

ONLY properly trained personnel who have read and understand this section should refill the fuel tank system.

This generator has an internal fuel tank located inside the trailer frame and may also be equipped with an environmental fuel tank (Figure 29). ALWAYS fill the fuel tanks with clean 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.
