LUBRICATION
Use only high quality detergent oil rated
with API service classification SG-SL. Se-
lect the oil's SAE viscosity grade according
to your expected operating temperature.
SAE VISCOSITY GRADES
F -20 0 30 32 40 60 80 100
C -30 -20 -1; ; 17 20 10 4;
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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 )ossible
engine damage from running low on oil.
Change the oil after every 25 hours of op-
eration orat least once a year if the mower
is not used for 25 hours in one year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.

stopping every few ounces to check the
oil level with the dipstick.
Stop adding oil when you reach the
FULL mark on the dipstick. Wait a
minute to allow oil to settle.
