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.
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.
FIG. 16
AIR FILTER (See Fig. 16)
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
operation or every season, whichever occurs fi rst.
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. 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.
NOTE: Do not wash the paper cartridge or use pressurized
air, as this will damage the cartridge.
• Reinstall the pre-cleaner (cleaned and oiled) over the
paper cartridge.
