TO CHANGE ENGINE OIL (See Fig. 17)
Determine temperature range expected before oil change.
All oil must meet API service classification SF or SG.
• Be sure vehicle is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove oil fill 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 dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
Product Specifications on page 3 of this manual.
• Use gauge on oil fill dipstick for checking level. Insert
dipstick into the tube and rest the oil 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.
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 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. Tighten
oil fill cap/dipstick securely each time you check the oil
level.

AIR FILTER (See Fig. 17)
Your engine will not run properly using a dirty air filter.
Clean the foam pre-cleaner element after every 25 hours of
operation or every season. Service paper cartridge every
100 hours or every season, whichever occurs first.
Service air cleaner more often under dusty conditions.
• Remove knob and cover.
• Remove wing nut and air cleaner from base.
TO SERVICE PRE-CLEANER
• Slide foam pre-cleaner off cartridge.
• Wash it in liquid detergent and water.
• Squeeze it dry in a clean cloth.
• Saturate it in engine oil. Wrap it in clean, absorbent
cloth and squeeze to remove excess oil.
TO SERVICE CARTRIDGE
• Gently tap the flat side of the paper cartridge to dis-
lodge dirt. Do not wash the paper cartridge or use
pressurized air, as this will damage the cartridge.
Replace a dirty, bent, or damaged cartridge.
• Reinstall the pre-cleaner (cleaned and oiled) over the
paper cartridge.
• Reassemble air cleaner, wing nut, cover and tighten
knob securely.
