LUBRICATION

Use only high quality detergent oil rated with API service classification SG-SL. Se-

lect the oil's SAE viscosity grade accord- ing to your expected temperature.

SAE VISCOSITY GRADES

F -20	0	30	40	60	80	100
c -_o	-2;	-I;	_ /o	_o	1o	40

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

oil viscchar15÷(dl

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 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

starting the engine and after each five (5) hours of continuous use. Add SAE 30 mo-

tor 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 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.

1.Remove drain plug.

For easier removal of plug use 7/16- 12 Pt. socket with extension.

2.Tip tiller forward to drain oil.

3.After oil has drained completely, replace oil drain plug and tighten se- curely.

4.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

Your engine will not run properly using a dirty air filter. Clean the foam pre-cleaner after every 50 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.

1.Remove knob and cover. Lift air cleaner assembly off stud.

TO SERVICE PRE-CLEANER

2.Remove foam pre-cleaner from air filter.

3.Wash it in liquid detergent and water.

4.Squeeze it dry in a clean cloth. NOTE: If very dirty or damaged, replace pre-cleaner.

5.Reinstall pre-cleaner onto air filter.

6.Reinstall cover and secure with knob.

TO SERVICE CARTRIDGE

1.Carefully remove cartridge to prevent debris from entering carburetor. Clean base carefully to prevent debris from entering carburetor.

2.Remove foam pre-cleaner from air filter.

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

4.Reinstall pre-cleaner onto air filter.

5.Reinstall cover and secure with knob.

IMPORTANT: Petroleum solvents, such as kerosene, are not to be used to clean the cartridge. They may cause deterio- ration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge.
