INSPECTING FUEL FILTER

w

Gasoline (petrol) is highly flammable, and
its vapors are flammable and explosive.

8

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

8

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

8

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

8

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

8

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