BEFORE YOU OPERATE
Handling of Diesel Fuel
WARNING
Fire and Explosion Hazard.
• Only fill the fuel tank with diesel fuel.
Filling the fuel tank with gasoline may
result in a fire and will damage the
engine. Never refuel with the engine
running. Wipe up all spills
immediately. Keep sparks, open
flames or any other form of ignition
(match, cigarette, static electric
source) well away when refueling.
• Always put the diesel fuel container
on the ground when transferring the
diesel fuel from the pump to the
container. Hold the hose nozzle firmly
against the side of the container while
filling it. This prevents static
electricity buildup which could cause
sparks and ignite fuel vapors.
1. Water and dust in the fuel may cause
engine failure. When fuel is stored, be
sure that the inside of the storage
container is clean and dry, and that the
fuel is stored away from dirt or rain.

bottom of the tank so that only clean fuel is
distributed to the engine.
