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 OutputTerminals 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 31) on the dipstick. See Table 10 for proper selection of engine oil.

Figure 31. Engine Oil Dipstick

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 John Deere 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 - REFUELINGTHE GENERATOR

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

The generator unit has an internal fuel tank located at the bottom of the cabinet (Figure 32). ALWAYS fill the 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.
