FUEL CHECK
Refi lling the Fuel System
This generator has an internal fuel tank located inside
the trailer frame and may also be equipped with an
environmental fuel tank (Figure 29). 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
