• Keep the fuel tank and fuel-handling equipment
clean at all times.
• Poor-quality fuel can reduce engine performance
and / or cause engine damage.
• Fuel additives are not recommended. Some fuel
additives may cause poor engine performance.
Handling Diesel Fuel
DANGER! Be sure to place 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.
• Keep the diesel fuel in a clean container. Store
the container in a place away from rain and dirt as
water and dust mixed in with the fuel cause
engine failure.
• Keep the fuel container stationary for several
hours to allow any dirt or water to settle to the
bottom. Use a pump to extract the clear, filtered
fuel from the top of the container for use.
• Pump out only half-way to avoid pumping out any
contaminates or foreign matter in the bottom of
the tank (Figure 3-17).
