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.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could
create a fire hazard and/or damage.
SPARK PLUG(S)
Replace spark plug(s) at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs first.
Spark plug type and gap setting are
shown in "PRODUCT SPECIFICATIONS"
section of this manual.
