MAINTENANCE NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not. • Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced. GRASS CATCHER • The grass catcher may be hosed with water, but must be dry when used. • Check your grass catcher often for damage or deterioration. Through normal use it will wear. If catcher needs replacing, replace only with approved replacement catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering. GEAR CASES • To keep your drive system working properly, the gear cases and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season. • The gear cases are filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case. ENGINE LUBRICATION Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized engine manufacturer's service outlet. 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. TO CHANGE ENGINE OIL (See Figs. 16 & 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 oil fill cap/dipstick; lay aside on a clean sur- face. 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. CONTAINER FIG. 16 4. Wipe off any spilled oil from lawn mower or side of engine. 5. Fill engine with oil. Slowly pour oil 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 UPPER MARK 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. LOWER MARK FIG. 17 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 to retighten oil fill cap/dipstick before starting engine. 9. Reconnect spark plug wire to spark plug. 13
