check both rear wheels.

inside the dust cover, pinion and/or drive

LUBRICATION
Use only high quality detergent oil rated with
API service classification SF, SG or SHo
Select the oil's SAE viscosity grade according
to/our expected operating temperature.
SAE VISCOS_
I
: ÷20" a' 30 _ _2" 4'0;' 60' 801 _" I
NOTE: Although multiwiscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
these multi-viscos_ oils will result in increased
oil consumption when used above 32°E
Check your engine oi! 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 la_
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.
