CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the grass screen, 
cooling fi ns, and other external surfaces of the engine are 
kept clean at all times.
Every 100 hours of operation (more often under extremely 
dusty, dirty conditions), remove the blower housing and 
other cooling shrouds. Clean the cooling fi ns and external 
surfaces as necessary. Make sure the cooling shrouds are 
reinstalled.
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.
AIR FILTER (See Fig. 15)
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.

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.
CLEAN AIR SCREEN 
Air screen must be kept free of dirt and chaff to prevent 
engine dam age from overheating.  Clean with a wire brush 
or compressed air to re move dirt and stubborn dried gum 
fi bers.
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.
