OIL CHANGE
ca v_¢ cr,a,Ti o
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°E Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of op-
eration or at least once a year if the tractor
is not used for 25 hours in one year.
Check the crankcase
oil level before start-
ing 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
SF-SJ.
• 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.
4. To open, pull out on the drain valve.
5. After oil has drained completely, close
and lock the drain valve by pushing
inward and turning clockwise until the
pin is in the locked position as shown.
6. Remove the drain tube and replace the
cap onto the end of the drain valve.
7. Refill engine with oil through oil fill dip-
stick tube. Pour slowly. Do not overfill.
For approximate
capacity see "PROD-
UCT SPECIFICATIONS"
section of this
manual.
8. Use gauge on oil fill cap/dipstick
for
checking level. For accurate reading,
tighten dipstick cap securely onto the
tube before removing dipstick.
Keep oil
at "FULL" line on dipstick. Tighten cap
onto the tube securely when finished.
AIR FILTER
Your engine will not run properly using a
dirty air filter. Replace pre-cleaner after
every 25 hours of operation or every
season. Service paper cartridge every
100 hours of operation or every season,
whichever occurs first.
Service air cleaner more often under dusty
conditions.
1. Pull up on air filter cover handle and
rotate towards engine.
