Maintenance

●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.

Cleaning fuel filter

NOTE:

If any water is in the fuel, the float will rise. If so, remove the cup and drain the water.

1.Unscrew the filter cup, catching any spilled fuel in a rag.

2.Remove the filter element, and wash it in solvent. Allow it to dry. Inspect the filter el- ement and O-ring to make sure they are in good condition. Replace them if neces-

sary. If any water is found in the fuel, the Yamaha portable fuel tank or other fuel tanks should be checked and cleaned.

3.Reinstall the filter element in the cup. Make sure the O-ring is in proper position in the cup. Firmly screw the cup onto the filter housing.

4.Attach the filter assembly to the bracket.
