belts if they begin to slip from wear.
ENGINE
LUBRiCATiON
Only use high quality detergent oil rated with
API service classification SG-SL. Selectthe
oil's SAE viscosity grade according to your
expected operating temperature.
SAE VISCOSITY GRADES
c -30 _20 qo 0 10 20 3o 40
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
they will result in increased oil consumption
when used above 32°F/0°C. Check your
engine oil level more frequently to avoid
possible engine damage from running low
on oil.
Change the oil after every 50 hours of
operation or at least once a year if the tractor
is not used for 50 hours in one year.
Checkthe crankcase oil level before starting
the engine and after each eight (8) hours
of operation. Tighten oil fill cap/dipstick
securely each time you check the oil level.
TO CHANGE ENGINE OiL
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SL.
Ensure tractor is on level surface.
Oil will drain more freely when warm.
Catch oil in a suitable container.
