CLEAN AIR SCREEN

Air screen must be kept free of dirt and

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 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.

MUFFLER

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

SPARK PLUG(S)

Replace spark plug(s) at the beginning

of each mowing season or after every

100 hours of operation, whichever occurs

first. Spark plug type and gap setting are

shown in “PRCDUCT SPECIFICATICNS”

tor, replacement is required.

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.
