This generator has an internal fuel tank located inside the trailer frame and may also be equipped with an environmental fuel tank (Figure 31). 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.
