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 cooling 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.

AIR FILTER

Your engine will not run properly using a dirty air filter. Clean the foam pre-cleaner after every 25 hours of operation or

every season. Service paper cartridge every 100 hours of operation or every season, whichever occurs first.

Service air cleaner more often under dusty conditions.

•Loosen knob and remove cover.

TO SERVICE PRE-CLEANER

•Wash it in liquid detergent and water.

•Squeeze it dry in a clean cloth. Allow it to dry.

•Saturate it in engine oil. Wrap it in

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.

MUFFLER

and spark arrester (if equipped) as it could create a fire hazard and/or

damage.

first. Spark plug type and gap setting'are shown in "PRODUCT SPECIFICATIONS" section of this manual.

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 to clean your tractor unless the electrical system, muffler, air filter and carburetor are covered to keep water out.

22 ened engine life.
