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 re sult in increased oil consumption
when used above 32°F (0°C). Check your
en gine oil level more frequently to avoid
pos si ble engine damage from running low
on oil.
Change the oil after every 50 hours of
op er a tion 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 fi ve (5)
hours of continuous use. Add SAE 30 mo-
tor oil or equivalent. Tighten oil fi ller plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL

before oil change. All oil must meet API
service classifi cation SG-SL.
