Filling the Fuel Tank
Before filling fuel tank for the first
time:
WARNING
Fire and Explosion Hazard
Never refuel with the engine running.
Rinse fuel tank with kerosene or diesel
fuel. Dispose of waste properly.
To fill the fuel tank:
WARNING
Fire and Explosion Hazard
Operate bilge ventilation (blowers) for a
minimum of 5 minutes to purge fumes
from engine compartment after
refueling. Never operate bilge blower
while refueling. Doing so can pump
explosive fumes into the engine
compartment and result in an
explosion.
1. Clean the area around the fuel cap.
2. Remove the fuel cap from the fuel tank.
3. Fill the tank with clean fuel free of oil
and dirt.
WARNING
Fire and Explosion Hazard
Hold the hose nozzle firmly against
the filler port while filling.
This prevents static electricity
buildup which could cause sparks
and ignite fuel vapors.
4. Stop fueling when the gauge shows the
fuel tank is full.
WARNING
Fire and Explosion Hazard
Never overfill the fuel tank.
5. Replace the fuel cap and hand-tighten.
Over-tightening the fuel cap will
damage it.
