NOTE:
Although
multi-viscosity
oils
(5W-30,
10W-30,
etc.) improve
starting
in
cold weather,
they will result
in increased
oil consumption
when
used
above
32°F
(0°C).
Check
your engine
oil level more
frequently
to avoid
possible
engine
dam-
age from running
low on oil.
Change
the oil after every 25 hours
of
operation
or at least once a year if the tiller
is not used for 25 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.
