15). FIG. 15 ADJUST WHEELS FOR CULTIVATING (See Figs. 16 and 17) • Place blocks under right hand side of tiller and remove hairpin clip and clevis pin from right hand wheel. • Move wheel outward approximately 1 inch (2.5 cm) until hole in inner wheel hub lines up with inner hole in axle. • Replace clevis pin and hairpin clip on inside of wheel and remove blocks. • Repeat preceding steps on left hand side. NOTE: In extremely rough conditions and while cultivating, the wheels should be moved outward on the axle for in creased stability. tire_1 FIG. 16 CLEVIS PIN HAIRPIN CLIP INNER VIEW OF TIRE CLEVIS PIN HAIRPIN CLIP ti 2 FIG. 17 11 MAINTENANCE MAINTENANCE SCHEDULE FILL IN DATES AS YOU COMPLETE REGULAR SERVICE BEFORE EACH USEEVERY 5 HOURSEVERY 25 HOURSEVERY 50 HOURSSERVICE DATESEVERY SEASON Check Engine Oil Level Change Engine Oil 1,2 Oil Pivot Points Inspect Spark Arrester / Muffler Inspect Air Screen Clean or Replace Air Cleaner Cartridge 2 Clean Engine Cylinder Fins Replace Spark Plug RH Gear Case Grease Fitting (1oz.) 1 - Change more often when operating under a heavy load or in high ambient temperatures. 2 - Service more often when operating in dirty or dusty conditions. 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. All adjustments in the Service and Adjustments section of this manual should be checked at least once each season. • 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 Keep unit well lubricated (See “LUBRICATION CHART”). LUBRICATION CHART ..

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. 18 and 19) 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 con tain er. • 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 FILLER PLUG OIL LEVEL OIL DRAIN PLUG FIG. 19 AIR FILTER (See Fig. 20) Your engine will not run properly using a dirty air filter. Clean the foam pre-cleaner after every 25 hours of op era tion or every season. Service paper cartridge every 100 hours of operation or every season, which ev er occurs first. Service air cleaner more often under dusty conditions. • Remove cover screw and cover. TO SERVICE PRE-CLEANER • Remove foam pre-cleaner from air cleaner cover. • Wash it in liquid detergent and water. • Squeeze it dry in a clean cloth. • If very dirty or damaged, replace pre-cleaner. • Reinstall pre-cleaner into air cleaner cover. • Reinstall cover and secure screw. TO SERVICE CARTRIDGE • Carefully remove cartridge to prev...
