LUBRICATION
Use only high quality detergent oil rated
with API service classification SF-SJ. Se-
lect the oil's SAE viscosity grade accord-
ing to your expected temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
o_ v_c cha_l e
NOTE: Although multi-viscosity oils
(5W-30, 10W-30, etc.) improve starting in
cold weather, they will result in increased
oil consumption when used above 32°F
(0°C). Check your engine oil level more
frequently to avoid possible engine dam-
age 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 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 SF-SJ.
• 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.
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.
5. 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.
