AIR FILTER Your engine will not run properly using a dirty air filter. Clean the foam pre-cleaner after every 25 hours of operation or every season. Service paper cartridge every 100 hours of operation or every season, whichever occurs first. See engine manual. MUFFLER Inspect and replace corroded muffler and spark arrester (if equipped) as it could create a fire hazard and/or damage. SPARK PLUGS Replace spark plugs at the beginning of each mowing season or after every 100 hours of operation, whichever occurs first. Spark plug type and gap setting are shown in "PRODUCT SPECIFICATIONS" section of this manual. IN-LINE FUEL FILTER (See Fig. 16) The fuel filter should be replaced once each season. If fuel filter becomes clogged, obstructing fuel flow to carburetor, replacement is required. • With engine cool, remove filter and plug fuel line sections. • Place new fuel filter in position in fuel line with arrow pointing towards carburetor. • Be sure there are no fuel line leaks and clamps are properly positioned. • Immediately wipe up any spilled gasoline. CLAMP CLAMP FUEL FILTER FIG. 16 CLEANING • Clean engine, battery, seat, finish, etc. of all foreign matter. • Keep finished surfaces and wheels free of all gasoline, oil, etc. • Protect painted surfaces with automotive type wax.

Water in engine can result in a shortened engine life. 18
