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 classification SG-SL. Select the oil’s SAE viscosity grade according to your expected temperature.

SAE VISCOSITY GRADES

						SAE 30
		10W-30 / 5W		-30
F	-20	0	30		40	60	80	100
C	-30	-20	-10		4 10	20	30	40

FIG. 16

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 40°F (4°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 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. 16 and 17)

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 container.

•Remove drain plug. For easier removal of plug use 7/16 12 Pt. socket with extension.)

•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.

AIR FILTER (See Fig. 18)

Your engine will not run properly using a dirty air filter. Clean the foam pre-cleaner after every 25 hours of operation or every season. Service paper cartridge every 100 hours of operation or every season, whichever 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 prevent debris from entering carburetor. Clean base carefully to prevent debris from entering carburetor.

•Clean cartridge by tapping gently on flat surface. If very dirty or damaged, replace cartridge.

•Reinstall cartridge, cover with pre-cleaner and secure with screw.

IMPORTANT: PETROLEUM SOLVENTS, SUCH AS KEROSENE, ARE NOT TO BE USED TO CLEAN THE CARTRIDGE. THEY MAY CAUSE DETERIORATION OF THE CARTRIDGE. DO NOT OIL CARTRIDGE. DO NOT USE PRESSURIZED AIRTO CLEAN OR DRY CARTRIDGE.
