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 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.
• 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-
cu rely.
4. Remove oil filler plug. Be careful not to
allow dirt to enter the engine.
5. Refill engine with oil. See "FILL
ENGINE WITH OIL" in the Operation
