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 tow
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.
