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 re-
moved will cause engine damage due to overheating.
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.
o Drain oil from engine crankcase (See '%0CHANGE ENGINE OIL" in this sec-
tion of this manual, through step remove drain plug)o

CLEANING
°Clean engine, battery, seat, finish, etc. of all foreign matter.

We do not recommend using a garden hose to clean your tractor unless the elec- trical system, muffler, air filter and carbu- retor are covered to keep water out. Water
in engine can result in a shortened engine life.
