NOTE: Although multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, these multi-
viscosity oils will result in increased oil consumption
when used above 32
o
F. Check your snow throwers
engine oil level more frequently to avoid possible
engine damage from running low on oil.
Refer to the viscosity chart for proper selection of
engine oil.
Checking Oil Level
Before operating the snow thrower, check the oil
level.
With engine on level ground, the oil must be to
FULL mark on dipstick.
Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and
dipstick.
Wipe dipstick clean, insert it into oil fill hole and
tighten securely.
Remove dipstick and check. If oil is not up to the
FULL mark on dipstick, add oil.
Changing Oil
Change engine oil after first two hours of operation
and every 25 hours thereafter.
In order to change the oil, you will have to first drain
the spent engine oil from the engine and then refill
with fresh oil.
