ENGINE OIL FILTER

Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year.

AIR FILTER

Your engine will not run properly using a dirty air filter. Service air cleaner more often under

dusty conditions. See Engine Manual.

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 airto remove dirt and stubborn dried gum fibers.

ENGINE COOLING SYSTEM

To ensure 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. Ensure the cooling shrouds are reinstalled.

NOTE: Operating the engine with a blocked grass screen, dirty or plugged cooling fins, and/or cooling shrouds removed wilt cause engine damage due to overheating.

MUFFLER

inspect and replace corroded muffler and spark arrester (if equipped) as it could create a fire hazard and/or damage.

SPARK PLUG(S)

Replace spark plug(s) atthe beginning of each mowing season or after every 100 hours of operation, whichever occurs first. Spark plug type and gap setting are shown in"PRODUCT SPECIFICATIONS" section of this manual.

Points

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 transmission 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.
