LUBRICATION
Use only high quality detergent oil rated
with API service classification SF, SG or
SH. Select the oil’s SAE viscosity grade
according to your expected temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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 oi) 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 start­
ing 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
Determine temperature range expected
before oil change. All oil must meet API
service classification SF, SG or SH.
• Be sure titter is on level surface.
• OH will drain more freely when warm.
• Use a funnel to prevent oil spill on tiller,
and catch oil in a suitable container.
• Remove oil drain plug. Be careful not to
allow dirt to enter the engine. For easier
removal of plug use 7/1612 R. socket
with extension.
• Up tiller forwarcTto drain oil.
After oil has drained completely, replace
oil drain plug and tighten securely.
Remove oil fill plug.
Refill engine with oil through oil fill tube.
See “CHECK ENGINE OIL LEVEL’ in
the Operation section of this manual.
Replace oil fill plug and tighten securely.

whichever occurs first.
Service air cleaner more often under dust;
conditions. '
• Remove knob and cover. Lift air cleanei
assembly off stud.
TO SERVICE PRE-CLEANER
• Remove foam pre-cleaner from air filter
• Wash it in liquid detergent and water.

• If very.dirty or damaged, replace pre-
cleandr.
• Reinstall pre-cleaner onto air filter.
• Reinstall cover and secure with knob.
TO SERVICE CARTRIDGE
• Carefully remove cartridge to prevent
debris from entering carburetor. Clean
base carefully to prevent debris from
entering carburetor.
• Remove foam pre-cleaner from air filtei
• Clean cartridge by tapping gently on flat
surface. If very dirty or damaged,
replace cartridge.
• Reinstall pre-cleaner onto air filter.
•
Reinstall cover and secure with knob.
IMPORTANT: Petroleum solvents, such
as kerosene, are not to be used to clean
the cartridge. They may cause deteriora
