2 - Service more often when operating in dirty or dusty conditions. LUBRICATION CHART GENERAL RECOMMENDATIONS The warranty on this tiller does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must main tain tiller as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your tiller. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual. • Once a year you should replace the spark plug, clean or replace air filter, and check tines and belts for wear. A new spark plug and clean air filter assure proper air-fuel mixture and help your engine run better and last longer. BEFORE EACH USE • Check engine oil level. • Check tine operation. • Check for loose fasteners. LUBRICATION .. EN GINE .. TINE CON TROL .. IDLER ARM Keep unit well lubricated (See “LUBRICATION CHART”). ..SAE 30 OR 10W-30 MOTOR OIL ..REFER TO MAINTENANCE “ENGINE” SECTION 10 MAINTENANCE Disconnect spark plug wire before performing any maintenance (except car bu re tor adjustment) to prevent accidental start ing of engine. Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Re move fuel from tank before tipping unit for maintenance. Clean muffler area of all grass, dirt, and debris. Do not touch hot muffler or cylinder fins as contact may cause burns. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SG-SL. Select the oil’s SAE vis cos i ty grade according to your expected temperature.

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. 11 and 12) 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. • Catch oil in a suitable container. • Remove drain plug. • 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. OIL DRAIN PLUG OIL LEVEL Fig. 12 OIL FILLER PLUG AIR CLEANER (See Fig. 13) Service air cleaner cartridge every twenty-five hours, more often if engine is used in very dusty conditions. • Loosen air cleaner screws, one on each side of cover. • Remove air cleaner cover. • Carefully remove air cleaner cartridge. Be care ful. Do not allow dirt or de bris to fall into carburetor. • Clean by tapping gently on a flat surface. • If very dirty or damaged, replace cartridge. • Clean and re place cover. Tighten screws securely. AIR CLEANER SCREW CAUTION: Petroleum sol vents, such as kerosene, are not to be used to clean cartridge. They may cause de te ri o ra tion of the cartridge. Do not oil car tridge. Do not use pres sur ized air to clean or dry cartridge. AIR CLEAN ER CAR TRIDGE COV ER Fig. 13 COOLING SYSTEM (See Fig. 14) Your engine is air cooled. For proper engine performance and long life keep your engine clean. • Clean air screen frequently using a stiff-bristledbrush. • Remove blower housing and clean as nec es sary. • Keep cylinder fins free of dirt and chaff. CYLINDER FINS MUF FLER BLOWER HOUSING Fig. 14 AIR SCREEN 11 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 “PROD UCT SPEC I FI CATIONS” on page 3 of this manual. TRANSMISSION Your transmission is sealed and will not require lubrication unless serviced. CLEANING Do not clean your tiller when the engine and transmission are hot. We do not rec om mend using pressurized water (gar den hose, etc.) to clean your unit un less the gasket area ...
