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
_F -20 _ 0_ 30 _ 32 _ 40 _ 60_ 80 = _00"
_=C -30 = -20 _ -10" .......... 08......... 10_ 20 _ 30 _ 40"
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
FIG. 15

improves starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°C, Check your engine oil level more frequently to avoid
possible engine damage from running low on oil,,
Change the oil after the first two hours.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 continuous use,,
TO CHANGE ENGINE OIL (See Figs. 15 and 16)
Determine temperature range expected before oil change,
All oi! must meet API service classification SF or SGo
o Be sure tractor is on level surface.
o Oil will drain more freely when warm,
= Catch oilin a suitable container_
= Remove oil fill cap/dipstick, Be careful not to allow dirt
to enter the engine when changing oil,

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
