MAINTENANCE TO CHANGE ENGINE OIL (See Figs. 11 & 12) 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. 13) 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. CONTAINER SLOT TAB FIG. 11 4. Wipe off any spilled oil from mower or side of engine. 5. Fill engine with oil. The engine oil capacity is 18.5 oz. If oil is not completely drained from engine, you may not need the entire container of a 20 oz. bottle of oil. Slowly pour 3/4 of the oil from the container down the oil fill spout into the engine. 6. Wait one minute to allow oil to settle. Use guage on oil fill cap/dipstick for checking level. Insert dipstick into the tube and rest the oil fill cap on the tube. DO NOT thread the cap into the tube when taking reading. OIL FILL CAP / DIPSTICK CARTRIDGE FILTER COVER MUFFLER FIG. 12 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. UPPER MARK CLEANING IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN THE UNDERSIDE OF YOUR MOWER AFTER EACH USE. LOWER MARK CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug. FIG. 12 • 7.

Always be sure to retighten oil dipstick before starting • engine. 9. Reconnect spark plug wire to spark plug. • 11 Clean the underside of your lawn mower by scraping to remove build-up of grass and trash. Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life. Keep finished surfaces and wheels free of all gasoline, oil, etc. We do not recommend using a garden hose to clean 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.
