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.
