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 stubborn dried gum fibers.

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 airfilter. Clean the foam pre- cleaner after every 25 hours of operation or every season. Service paper car- tridge every 100 hours of operation or

every season, whichever occurs first. Service air cleaner more often under

dusty conditions.

•Remove knob and cover.

•Remove wing nut and air cleaner from base.

TO SERVICE PRE-CLEANER

•Slide foam pre-cleaner off cartridge.

•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 clean, absorbent cloth and squeeze to remove excess oil.

TO SERVICE CARTRIDGE

•Replace a dirty, bent, or damaged cartridge.

NOTE: Do not wash the paper cartridge or use pressurized air, as this will

damage the cartridge.

•Reinstall the pre-cleaner (cleaned and oiled) over the paper cartridge.

•Reassemble air cleaner, wing nut, cover and tighten knob securely.

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.

•Drain oil from engine crankcase (See "TO CHANGE ENGINE OIL" in this

section of this manual, through step remove drain plug).

•Remove oil filter and wipe off filter adapter.

•Apply a thin coating of new engine oil to the rubber gasket on replacement oil filter.

•Install replacement oil filter on filter adapter. Turn oil filter clockwise until rubber gasket contacts the filter

adapter, then tighten filter an addi- tional 1/2 turn.

•Fill crankcase with new oil (See "TO CHANGE ENGINE OIL" in this section

of this manual). For approximate

capacity see "PRODUCT SPECIFICA- TIONS"section of this manual.

•Start the engine and check for oil leaks. Correct any leaks before placing engine into full operation.
