TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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 start-
ing 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.
