CLEAN AIR SCREEN
Air screen must be kept free of dirt and

CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other exter­
nal 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 fins
and external surfaces as necessary. Make
sure the cooling shrouds are reinstalled.
NOTE: Cperating the engine with a
blocked grass screen, dirty or plugged
cooling fins, and/or cooling shrouds
removed will cause engine damage due to
overheating.

spark arrester (if equipped) as it could cre­
ate a fire hazard and/or damage.

100 hours of operation, whichever occurs
first. Spark plug type and gap setting are
shown in “PRCDUCT SPECIFICATICNS”

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 automo­
tive 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 com­
pressed air or a leaf blower to remove
grass, leaves and trash from tractor and
mower.
