ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SF or SG. Select the oil's SAE viscosity grade
according to your expected operating temperature.
SAE VISCOSITY GRADES
-20" 0" 30" 32 ° 40" 60 ° 80 °
-30_ -20_ -10' O" 10" 20° 30" 40=
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
possible engine damage from running low on oil
Change the oil after' the first two hour's of operation and
every 50 hours thereafter or at least once a year if the
tractor is not used for 50 hours in one year
Check the 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 (See Fig 14)

, Oil will drain more freely when warm.
° Catch oil in a suitable container.
• Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil

• After oil has drained completely, replace oil drain plug
and tighten securely.
= Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill For approximate capacity see
"PRODUCT SPECIFICATIONS" on page 3 of this
manual
Use gauge on oil fill cap/dipstick for checking level.
Insert dipstick into the tube and rest the oil fill cap on the
tube. Do not thread the cap onto the tube when taking
reading. Keep oil at "FULL" line on dipstick. Tighten
cap onto the tube securely when finished.
