PRE-CLEANER MAINTENANCE HANDLE COVER CARTRIDGE 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 use, whichever comes first. Spark plug type and gap setting is shown in "PRODUCT SPECIFICATIONS" section of this manual. IN-LINE FUEL FILTER (See Fig. 14) 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 sec- tions. • 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 BASE TABS SLOTS FIG. 12 ENGINE COOLING FINS (See Fig. 13) Remove any dust, dirt or oil from engine cooling fins to prevent engine damage from overheating. • Remove screws from blower housing and lift housing and dipstick tube assembly off engine. • Cover oil fill opening to prevent entry of dirt. • Use compressed air or stiff bristle brush to thoroughly clean engine cooling fins. • To reassemble, reverse above procedure. SCREWS BLOWER HOUSING SCREWS FIG. 14 FUEL FILTER 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. We do not recommend using a garden hose or pressure washer to clean your tractor unless the engine and transmission are covered to keep water out. Water in engine or transmission will shorten the useful life of your tractor. Use compressed air or a leaf blower to remove grass, leaves and trash from tractor and mower.
