Consult an authorized dealer for details on
handling of gasoline, if necessary.
Gasoline and its vapors are very flammable
and can be explosive.
When carrying a fuel tank containing gaso-
line:
 Close the air vent screw of fuel tank cap,
or gasoline vapor will be emitted
through the air vent screw, creating a
fire hazard.
 Do not smoke.
When or before refueling :
 Stop the engine, and do not start the
engine during refueling.
 Do not smoke.
 Be careful not to overfill fuel tank. Wipe
up any spilled gasoline immediately.
When or before cleaning the gasoline tank :
 Dismount fuel tank from the boat.
 Place the fuel tank away from every
source of ignition, such as sparks or
open flames.
 Do the work outdoors or in well venti-
lated area.
 Wipe up any spilled gasoline immedi-
ately.
After cleaning gasoline tank :
 Wipe up any spilled gasoline immedi-
ately.
 If the fuel tank is disassembled for
cleaning, reassemble carefully. Imper-
fect assembly may cause a fuel leak,
possibly leading to fire or explosion.
 Dispose of aged or contaminated gaso-
line in accordance with local regulations.
Use of low-quality gasoline results in a
short engine life as well as starting difficul-
ties and other engine problems.
We recommend use for Fuel stabilizer.
Use of unleaded gasoline
Use a major brand of automotive unleaded
gasoline with a minimum posted octane
rating of 91RON. Automotive gasoline that
contain fuel injector cleaner are preferred
for added internal engine cleanliness.
Leaded gasoline is acceptable in areas
where unleaded gasoline is not available.
