TEMPE,A_RE _NaEA,TICI_ATED BE_RE NEXT OIL C,_OE 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 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 ever,./50 hours of operation or at least once a year if the tiller is not used for 50 hours in one year. Check the crankcase oil level before start- ing 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 Determine temperature range expected before oil change. All oil must meet API service classification SF, SG or SH. 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, ° 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. Remove air cleaner asssembly from inside cover and disassemble. TO SERVICE PRE-CLEANER o Wash it in liquid detergent and water. o Squeeze it dry in a clean cloth. ° Saturate it in engine oil.
