push down firmly into place before removing. Keep oil
up to, but not over, the "FULL " line on dipstick. Push
dipstick down firmly into the tube when finished.
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent
engine dam age from overheating. Clean with a wire brush
or compressed air to re move 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 re-
moved will cause engine damage due to overheating.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Service air cleaner more often under dusty conditions.
See Engine Manual.
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. See engine manual.

CLEANING

•
We do not recommend using a garden hose or pressure
washer to clean your tractor unless the engine and trans-
mission 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.
