whichever occurs first.
Service air cleaner more often under dusty
conditions.

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 stub-
born dried gum fibers.
CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other exter-
nal surfaces of the engine are kept clean
at all times.
Every 106 hours of operation (more often
under extremely dusty, dirty conditions),
remove the blower housing and other cool-
ing 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.
