chaff to prevent engine damage from
overheating. Clean with a wire brush or
compressed air to remove dirt and stub­
born dried gum fibers.
CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, 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 cool­
ing shrouds. Clean the cooling fins 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 fins, and/or cooling shrouds
removed will cause engine damage due to
overheating.

CLEANING
• Clean engine, battery, seat, finish, etc.
of all foreign matter.
• Keep finished surfaces and wheels free
of all gasoline, oil. etc.
• Protect painted surfaces with auto­
motive type wax.
We do not recommend using a garden
hose or pressure washer to clean your
tractor unless the engine and transmis­
sion 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.
