NOTE
: Before tipping lawn mower to

gine until fuel tank is empty

clean surface.
3.

.
Rock lawn mower back and forth to re-
move any oil trapped inside of engine.
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°F
. Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the
lawn mower is not used for 25 hours in
one year
.
Check the crankcase oil level before
starting the engine and after each fi
ve
(5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
