engine. Check for buildup of dirt and debris around
the air cleaner system. Keep this area clean. Also
check for loose or damaged components. Replace all
bent or damaged air cleaner components.

air cleaner components could allow unfiltered
air into the engine causing premature wear
and failure.

cooling fins, and other external surfaces of the engine
are kept clean at all times.
Every 50 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.
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.
Check
Spark Plug
Every 100 hours of operation, remove the spark plug,
check its condition, and reset the gap or replace with a

using abrasive grit. Some grit could
remain in the spark plug and enter the
engine causing extensive wear and
damage.
