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 every 25 hours of
operation 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/dip-
stick securely each time you check the oil
level,
TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. Ail oil must meet API
service classification SF, SG or SH.
» Be sure tractor is on level surface.
® 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.
Remove drain plug.
After oil has drained completely, replace
oil drain plug and tighten securely.
Refill engine with oil through oil fill dip­
stick tube. Pour slowly. Do not overfill.
For approximate capacity see “PROD­
UCT SPECiFICATiONS” on page 5 of
this manual.
Use gauge on oil fill cap/dipstick for
checking level. Be sure dipstick cap is
tightened securely for accurate reading.
Keep oil at “FULL” line on dipstick.
AIR FILTER
Your engine will not run properly using a
dirty air filter. Clean the foam 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.
» Remove knob(s) and cover.
TO SERVICE PRE-CLEANER
