Select the oil’s SAE vis cos i ty grade according to your expected temperature. ........................................................................................................................................................................................................................ Fig. 18 NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 40°F (4°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 motor oil or equivalent. Tighten oil filler plug securely each time you check the oil level. TO CHANGE ENGINE OIL (See Figs. 18 and 19) • 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 con tain er. • Remove drain plug. OIL DRAIN PLUG OIL FILLER PLUG OIL LEVEL Fig. 19 • For easier removal of plug use 7/16 12 Pt. socket with extension. • Tip tiller forward to drain oil. • After oil has drained completely, replace oil drain plug and tighten securely. • Remove oil filler plug. Be careful not to allow dirt to enter the engine. • Refill engine with oil. See “CHECK ENGINE OIL LEVEL” in the Operation section of this manual. CLEANING AIR CLEANER A dirty air cleaner element will cause starting difficulty, power loss, engine malfunctions, and shorten engine life extremely. Always keep the air cleaner element clean. DUAL ELEMENT TYPE • Urethane Foam cleaning (See Fig. 20) Wash and clean the urethane foam with detergent. After cleaning, dry it. Clean the urethane foam element every 50 hours. • Second element (See Fig. 20) Clean by tapping gently to remove dirt and blow off dust. Never use oil. Clean the paper element every 50 hours of operation, and replace element set every 200 hours. Clean and replace air cleaner elements more often when operating in dusty environments. Fig. 20 FOAM ELEMENT ELEMENT WING NUT COVER 12 MAINTENANCE MUFFLER Do not operate tiller without muffler. Do not tamper with exhaust system. Damaged mufflers or spark arresters could create a fire hazard. Inspect pe ri odi cally and re place if nec es sary. If your engine is equipped with a spark arrester screen assembly, re move every 50 hours for cleaning and inspection. Re place if dam aged. SPARK PLUG Replace spark plugs at the beginning of each tilling season or after every 50 hours of use, whichever comes first. Spark plug type and gap setting are shown in “PRODUCT SPECIFICATIONS” on page 4 of this manual. TRANSMISSION Your transmission is sealed and will not re quire lubrication unless serviced. COOLING SYSTEM (See Fig. 21) Your engine is air cooled.
