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.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service classifi cation SG-SL. Select the oil’s SAE viscosity grade according to your expected temperature.

SAE VISCOSITY GRADES

							SAE 30
			5W-30
F	-20	0			30 32 40		60	80	100
C	-30	-20		-10	0	10	20	30	40

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

FIG. 11

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 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 fi ve (5) hours of continuous use. Add SAE 30 motor oil or equivalent. Tighten oil fi ller 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 classifi cation 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 fi ller plug. Be careful not to allow dirt to enter the engine.

•Refill engine with oil. See “CHECK ENGINE OILLEVEL” in the Operation section of this manual.
