CLEAN AIR SCREEN

Air screen must be kept free of dirt and 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 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 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.

MUFFLER

Inspect and replace corroded muffler and spark arrester (if equipped) as it could cre- ate a fire hazard and/or damage.

SPARK PLUG(S)

first. Spark plug type and gap setting are

shown in "PRODUCT SPECIFICATIONS" section of this manual.

,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,

201eaves and trash from tractor and mower.
