MAINTENANCE AIR FILTER (See Fig. 18) Your engine will not run properly and may be damaged by using a dirty air filter. Replace the air filter every 100 hours of operation or every season, whichever occurs first. Service air cleaner more often under dusty conditions. TO CLEAN AIR FILTER 1. Remove cover. 2. Carefully remove cartridge. 3. Clean by gently tapping on a flat surface. If very dirty, replace cartridge. CAUTION: Petroleum solvents, such as kerosene, are not to be used to clean cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge. 4. Install cartridge, then replace cover. SLOT TAB • Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life. • Keep finished surfaces / wheels free of gasoline, oil, etc. • With the exception of the water washout port (if equipped), we do not recommend using a garden hose to clean the outside of your lawn mower unless the electrical system, muffler, air filter and carburetor are covered to keep water out. Water in engine can result in shortened engine life. WATER WASHOUT FEATURE (See Fig. 19) Your lawn mower is equipped with a fitting that allows quick and easy cleaning of the underside of the housing. To use this feature, proceed as follows: 1. Move lawn mower to an area of cut grass or another hard surface. NOTE: Water, grass and other debris will drain from beneath the mower housing during the washout process. 2. Remove grass catcher and discharge chute assembly from lawn mower. 3. Close mulcher door (if equipped). 4. Connect a garden hose to the fitting where shown. IMPORTANT: BE SURE THE GARDEN HOSE IS NOT ROUTED UNDER THE LAWN MOWER HOUSING OR ENTANGLED IN THE WHEELS. 5. Turn on water supply and check for leaks at the fitting. If no leaks are present, start engine (as described in the Operation section of this manual) and let engine run until the underside of the lawn mower is clean. WARNING: Do not engage the drive system during the washout process. CARTRIDGE 6. Shut off the engine. 7. Shut off water supply and remove hose from fitting. FILTER COVER MUFFLER FIG. 18 Inspect and replace corroded muffler as it could create a fire hazard and/or damage. SPARK PLUG Replace spark plug 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 the "PRODUCT SPECIFICATIONS" section of this manual. CLEANING IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN THE UNDERSIDE OF YOUR MOWER AFTER EACH USE. CAUTION: Do not remove hose from fitting while engine is running. Water in engine can result in shortened engine life. 8. Start engine (as described in the Operation section of this manual) and let engine run for a full minute to remove excess water from mower. HOSE CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug. • Clean the underside of your lawn mower by scraping to remove build-up of grass and trash. 14 FITTING FIG. 19
