MAINTENANCE NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level. TO CHANGE ENGINE OIL (See Fig. 17) NOTE: Before tipping lawn mower to drain oil, empty fuel tank by running engine until fuel tank is empty. 1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug. 2. Remove engine oil cap; lay aside on a clean surface. 3. Tip lawn mower on its side as shown and drain oil into a suitable container. Rock lawn mower back and forth to remove any oil trapped inside of engine. 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 cartridge every 100 hours of operation or every season, whichever occurs first. Service air cleaner more often under dusty conditions. TO CLEAN AIR FILTER 1. Loosen screw and tilt cover to remove. 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 making sure the tabs are aligned with the slots in the back plate. Fasten screw securely.
