ENGINE
LUBRICATION
Use only high quality detergent oil rated
with API service classifi cation SF-SJ. Se-
lect the oil's SAE vis cos i ty grade accord-
ing to your expected temperature.
NOTE: Although multi-viscosity oils
(5W-30, 10W-30, etc.) improve starting in
cold weather, they will re sult in increased
oil consumption when used above 40°F
(4°C). Check your en gine oil level more
frequently to avoid pos si ble engine dam-
age from running low on oil.
Change the oil after every 25 hours of
op er a tion or at least once a year if the tiller
is not used for 25 hours in one year.
Check the crankcase oil level before
start ing the engine and after each fi ve (5)
hours of continuous use. Add SAE 30 mo-
tor oil or equivalent. Tighten oil fi ller plug
se cure ly each time you check the oil level.
TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classifi cation 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 con tain er.
1. Remove drain plug.
2. Tip tiller forward to drain oil.
3. After oil has drained completely,
re place oil drain plug and tighten se-
cure ly.
4. Remove oil fi ller plug. Be careful not to
allow dirt to enter the engine.
5. Refi ll engine with oil. See "CHECK
EN GINE 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 fi lter.

curs fi rst. 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 fl at sur-
face. If very dirty, replace cartridge.
CAUTION: Petroleum solvents, such as

MUFFLER
Do not operate tiller without muffl er. Do
not tamper with exhaust system. Dam-
aged muf fl ers or spark arresters could
create a fi re hazard. Inspect pe ri odi cally
and re place if nec es sary. If your engine is
equipped with a spark arrester screen as-
sem bly, re move every 50 hours for clean-
ing and inspection. Re place if dam aged.
