CLEANING
• Clean engine, battery, seat, fi nish, etc. of all foreign
matter.
• Keep fi nished surfaces and wheels free of all gasoline,
oil, etc.
• Protect painted surfaces with automotive type wax.
We do not recommend using a garden hose or pressure
washer to clean your tractor unless the engine and trans-
mission are covered to keep water out. Water in engine or
transmission will shorten the useful life of your tractor. Use
compressed air or a leaf blower to remove grass, leaves
and trash from tractor and mower.
NOTE: Operating the engine with a blocked grass screen,
dirty or plugged cooling fi ns, and/or cooling shrouds re moved
will cause engine damage due to overheating.
ENGINE OIL FILTER
Replace the engine oil fi lter every season or every other
oil change if the tractor is used more than 100 hours in
one year.
AIR FILTER (See Fig. 17)
Your engine will not run properly using a dirty air fi lter. Clean
the foam pre-cleaner after every 25 hours of op er a tion or
every season. Service paper cartridge every 100 hours of
op er a tion or every season, whichever occurs fi rst.
Service air cleaner more often under dusty conditions.
• Loosen knobs and remove cover.
TO SERVICE PRE-CLEANER
• Remove foam pre-cleaner from cover.
• Wash it in liquid detergent and water.
• Squeeze it dry in a clean cloth. Allow it to dry.
• Saturate it in engine oil. Wrap it in clean, absorbent
cloth and squeeze to remove excess oil.
TO SERVICE CARTRIDGE
• Replace a dirty, bent, or damaged cartridge. Handle
new cartridge carefully; do not use if the rubber seal
is damaged.
NOTE: Do not wash the paper cartridge or use pressurized
air, as this will damage the cartridge.
• Remove cartridge.
• Gently tap pleated side of cartridge to dislodge dirt.
• Install cleaned or new cartridge with the pleated side
“out” and seat the rubber seal onto the edges of the
air cleaner base.
• Reinstall the pre-cleaner (cleaned and oiled) into the

with the upper mounting
knob.
