ENGINE
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.

AMBIENT TEMPERATURE
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 40°F
(4°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 and may
be damaged by using a dirty air filter.
Replace the air filter every 100 hours of
operation or every season, whichever oc-
curs first. Service air cleaner more often
under dusty conditions.
TO CLEAN AIR FILTER
1. Remove cover.
2. Carefully remove cartridge.
3. Clean by gently tapping on a flat sur-
face. If very dirty, replace cartridge.
_:i,CAUTION: Petroleum solvents, such as
kerosene, are not to be used to clean car-
tridge. They may cause deterioration of the
cartridge. Do not oil cartridge. Do not use
pressurized air to clean or dry cartridge.
4. Install cartridge, then replace cover.

MUFFLER
Do not operate tiller without muffler. Do
not tamper with exhaust system. Dam-
aged mufflers or spark arresters could
create a fire hazard. Inspect periodically
and replace if necessary. If your engine is
equipped with a spark arrester screen as-
sembly, remove every 50 hours for clean-
ing and inspection. Replace if damaged.
