FUEL CHECK
Refilling the Fuel System
This generator has an internal fuel tank located inside the
generator enclosure 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.
