Filling the Fuel Tank
Before filling fuel tank for the first
time:
1.
Rinse fuel tank with kerosene or diesel
fuel. Dispose of waste properly.
To fill the fuel tank:
NOTICE: 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. NOTICE: 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. NOTICE: NEVER overfill
the fuel tank.
5.
Replace the fuel cap and hand-tighten.
Over-tightening the fuel cap will
damage it.
Bleeding the Fuel System
The fuel system has an automatic air
bleeding device that purges air from the fuel
system. No manual air bleeding is required
for normal operation. Bleeding must be
done if any fuel system maintenance has
been performed (replacement of fuel filter,
etc.) or if the engine does not start after
several attempts.
