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.

TEMPERATURE RANGE ANTICIPATED BEFORE NF.3_TOIL CHANGE
NOTE: Although multi-viscosity oils (5W30,
10W30 etco) improve starting in cold weather,
they wilt result in increased oil consumption
when used above 32°R 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 opera-
tion 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
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SLo
Be sure tractor is on level surface.
Oil will drain more freely when warm.
Catch oil in a suitable container°
1. Remove oil fill cap/dipstick. Be careful
not to allow dirt to enter the engine when
changing oil.
2. Remove yellow cap from end of drain
valve and install the drain tube onto the
fitting.
3. Unlock drain valve by pushing inward
slightly and turning counterclockwise.

7, Refill enginewith oilthrough oilfill dipstick
tube. Pour slowly, Do not overfill. For
approximate capacity see "PRODUCT

8. Use gauge on oil fill cap/dipstick for
checking level. Insert dipstick into the
tube and rest the 0i! 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,
