CLEAN AIR SCREEN Air screen must be kept free of dirt and chaff to prevent engine damage from overheating. Clean with a wire brush or compressed air to remove dirt and stubborn dried gum fibers. CLEAN AIR INTAKE/COOLING AREAS To insure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. Every 100 hours of operation (more often under extremely dusty, dirty conditions), remove the blower housing and other cooling shrouds. Clean the cooling fins and external surfaces as necessary. Make sure the cooling shrouds are reinstalled. NOTE: Operating the engine with a blocked grass screen, dirty or plugged cooling fins, and/or cooling shrouds removed will cause engine damage due to overheating. MUFFLER Inspect and replace corroded muffler and spark arrester (if equipped) as it could create a fire hazard and/or damage. SPARK PLUG(S) Replace spark plug(s) at the beginning of each mowing season or after every 100 i_ours of operation, whichever occurs first. Spark plug type and gap setting are shown in "PRODUCT SPECIFICATIONS" section of this manual. IN-LINE FUEL FILTER The fuel filter should be replaced once each season. If fuel filter becomes clogged, obstructing fuel flew to carburetor, replacement is required. 1. With engine cool, remove filter and plug fuel line sections. 2. Place new fuel filter in position in fuel line with arrow pointing towards carburetor. 3. Be sure there are no fuel line leaks and clamps are properly positioned. 4. Immediately wipe up any spilled gasoline. 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.
