WARNING

EWM00310

Gasoline is highly flammable, and its va-
pors are flammable and explosive.

●

If you have any question about properly
doing this procedure, consult your
Yamaha dealer.

●

Do not perform this procedure on a hot
or running engine. Allow the engine to
cool.

●

There will be fuel in the fuel filter. Keep
away from sparks, cigarettes, flames or
other sources of ignition.

●

This procedure will allow some fuel to
spill. Catch fuel in a rag. Wipe up any
spilled fuel immediately.

●

The fuel filter must be reassembled
carefully with the O-ring, filter cup, and
hoses in place. Improper assembly or
replacement could result in a fuel leak,
which could result in a fire or explosion

hazard.
