TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
oi_ wscch_rt4 e
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.
TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SL.
, 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.

7. Refill engine with oil through oil fill dipstick
tube. Pour slowly. Do not overfill. For
approximate capacity see "PRODUCT

8. Use gauge on oil fill cap/dipstick for
checking level. For accurate reading,
insert dipstick into the tube and push
down firmly into place before removing.
Keep oil up to, but not over, the "FULl"
line on dipstick. Push dipstick down firmly
into the tube when finished.
CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other exter-
nal surfaces of the engine are kept clean
at all times.
Every 100 hours of operation (more often
under extremely dusty, dirty conditions),
remove the blower housing and other cooling
shrouds. Clean the cooling fins and external
surfaces as necessary. Make sure the cooling
shrouds are reinstalled.
NOTE: Operating the engine with a blocked
grass screen, dirty or plugged cooling fins,
and/or cooling shrouds removed will cause
engine damage due to overheating.
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff
to prevent engine damage from overheating.
Clean with a wire brush or compressed air to
remove dirt and stubborn dried gum fibers.
