ENGINE
LUBRICATION
Use only high quality detergent oil rated
with API service classification SF-SJ.
Select the oil’s SAE viscosity grade
according to your expected temperature.

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 32°F (0°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
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-SJ.
■ Be sure tiller is on level surface.
• Oil will drain more freely when warm.
* 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
securely.
Remove oil filler plug. Be careful not
to allow dirt to enter the engine.
Refill engine with oil. See “FILL
ENGINE WITH OIL" in the Operation
section of this manual.
