CLEAN AIR INTAKE/COOL ING 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.
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 au to -
mo tive type wax.
We do not recommend using a garden
hose to clean your tractor unless the
electrical system, muffl er, air fi lter and
car bu re tor are covered to keep water out.
Water in engine can result in a short ened
engine life.
Every 100 hours of operation (more often
under extremely dusty, dirty conditions),
remove the blower housing and other cool-
ing shrouds. Clean the cooling fi ns and
external surfaces as necessary. Make sure
the cooling shrouds are re in stalled.
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.
