Do not touch hot muffler or cylinder fins as contact may cause burns. ENGINE LUBRiCATiON 5. Refill engine with oil. See "CHECK ENGINE OIL LEVEE' in the Operation section of this manual. Oil drain Level Oil Fill Plug Use only high quality detergent oil rated with API service classification SG-SL Select the oil's SAE viscosity grade according to your expected temperature. SAE VISCOSITY GRADES =20 0 20 40 60 80 100°F | l l 1 J [ • 1 =30 =20 =10 0 10 20 30 40 ° C TEMPERATURE RANGE ANTiCiPATED BEFORE NEXT OiL CHANGE NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.) improve starting in cold weather, they will result in increased oil consumption when used above 32°F (0°C). 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 tiller 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. Add SAE 30 mo- tor oil or equivalent. Tighten oil filler plug securely each time you check the oil level. AiR CLEANER Service air cleaner cartridge every twenty-five hours, more often if engine is used in very dusty conditions. 1. Loosen air cleaner screw. 2. Remove air cleaner cover. 3. Carefully remove air cleaner cartridge. Be careful. Do not allow dirt or debris to fall into carburetor. 4. Clean by tapping gently on a flat surface. NOTE: If very dirty or damaged, replace cartridge. 5. Clean and replace cover. Tighten screw securely. _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. Air Cleaner Cartridge Pre-Cleaner Cover TO CHANGE ENGINE OIL Determine temperature range expected before oil change. All oil must meet API service classification SG-SL • Be sure tiller is on level surface. • Oil will drain more freely when warm. • Use a funnel to prevent oil spill on tiller, and catch oil in a suitable container. 1. Remove drain plug. 2. Tip tiller forward to drain oil. 3. After oil has drained completely, replace oil drain plug and tighten securely. 4. Remove oil filler plug.
