MAINTENANCE

Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent accidental starting of engine.

Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Remove 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.

AIR CLEANER (See Fig. 13)

Service air cleaner cartridge every twenty-five hours, more often if engine is used in very dusty conditions.

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.

•Loosen air cleaner screws, one on each side of cover.

•Remove air cleaner cover.

•Carefully remove air cleaner cartridge. Be careful. Do not allow dirt or debris to fall into carburetor.

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 SF-SJ.

•Clean by tapping gently on a flat surface.

•If very dirty or damaged, replace cartridge.

•Clean and replace cover. Tighten screws 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.

•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.
