INSPECTION/SETUP

CIRCUIT BREAKERS

To protect the generator from an overload, a 3-pole, 300 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 overfi ll. Make sure the generator is level and verify that the oil level is maintained between the two notches (Figure 27) on the dipstick. See Table 9 for proper selection of engine oil.

Figure 27. 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 refi ll with the specifi ed 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:

API Service Classifi cation CC/SC

API Service Classifi cation CC/SD

API Service Classifi cation CC/SE

API Service Classifi cation CC/SF

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 refi ll 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 28). ALWAYS fi ll the fuel tanks with clean fresh #2 diesel fuel. DO NOT fi ll 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 fi lling. Handle fuel in a safety container. If the container does not have a spout, use a funnel. Wipe up any spilled fuel immediately.
