Fuel Filter Maintenance
Use a hooked wire to extract the fuel filter from inside the fuel
tank. Remove and replace the filter element. Before reinstalling
the filter, inspect the condition of the fuel line. If damage or dete-
rioration are noted, the unit should be removed from service until
you can consult with an authorized servicing dealer.
Make sure you do not pierce the fuel line with the end of
the hooked wire. The line is delicate and can be damaged
easily.
Never operate the unit with a damaged or missing silencer
or spark arrester! Operating with a missing or damaged
spark arrester is a fire hazard and could also damage your
hearing.
Carbon deposits in silencer will cause a drop in engine output
and overheating. Spark arrestor screen must be checked pe-
riodically. Clean deposits from silencer.

Do not remove the silencer cover. If necessary, Please consult
your dealer.
