ENGINE
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.

5. Refill engine with oil. See “CHECK

ENGINE OIL LEVEL” in the Operation

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

oiLvfsc_char!5_e(drt)

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.

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

Tip tiller forward to drain oil.
After oil has drained completely,

replace oil drain plug and tighten se­

curely.

Remove oil filler plug. Be careful not to

allow dirt to enter the engine.
