NOTE: Although multi-viscosity oils (5W-
30, 10W-30, etc.) improve starting in cold
weather, these m ulti-viscosity oils will result in
increased oil consumption when used above
32°F (0°C). Checkyour engine oil level more
frequentlyto avoid possible engine damage
from running low on oil.
Change the oil after every 50 hours of opera-
tion or at least once a year if the tiller is not
used for 50 hours in one year.
Checkthe 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

before oil change. All oil must meet API
