MAINTENANCE LUBRICATION Use only high quality detergent oil rated with API service classification SG-SL. Select the oil's SAE viscosity grade according to your expected operating temperature. 7. Continue adding small amounts of oil and rechecking the dipstick until it reads full. DO NOT overfill, or engine will smoke on startup. 8. Always be sure retighten dipstick before starting engine. 9. Reconnect spark plug wire to spark plug. OIL FILL CAP / DIPSTICK NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level 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 Figs. 14 & 15) 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. UPPER MARK LOWER MARK FIG. 15 AIR FILTER (See Fig. 16) 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 CONTAINER TAB FIG. 14 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.

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. 12 CARTRIDIGE FILTER COVER FIG. 16
