Filling Fuel Tank
Avoid serious injury or death from a gasoline fire or explosion. Use caution
when filling fuel tanks. Always stop the engine and do not smoke or allow
open flames or sparks in the area while filling fuel tanks.
Fill fuel tanks outdoors away from heat, sparks, and open flames.
Always stop engine before refilling tanks.
Do not overfill the fuel tank. Fuel will expand in volume as its temperature rises
and can leak under pressure if the tank is completely filled.
The oil and fuel mixture should always be thoroughly mixed in an approved
container before pouring into motor fuel tank. Do not pour separately into fuel
tank.
Pour fuel into tank through a fine mesh strainer to remove dirt which may be
present.
PORTABLE FUEL TANK
Fill fuel tanks outdoors away from heat, sparks, and open flames.
Remove portable fuel tanks from boat to refill them.
Always stop engine before refilling tanks.
Do not completely fill the fuel tank. Leave approximately 10% of tank volume
unfilled. Fuel will expand in volume as its temperature rises and can leak under
pressure if tank is completely filled.
