BEFORE YOU OPERATE
To fill the fuel tank:
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
X
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.
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.
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.
