Air Intake/Cooling System

Clean Air Intake/Cooling Areas
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine
are kept clean at all times.
Annually or every 100 hours of operation, (more often
under extremely dusty, dirty conditions), remove the
blower housing and any other cooling shrouds. Clean
the cooling fins and external surfaces as necessary.
Make sure all parts are reinstalled. Torque the M6
blower housing fasteners to 7.7 N·m (68.3 in. lb.).
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.
