Cleaning the Blower
Housing
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 the cooling shrouds are installed. Torque
the blower housing screws to 7.5 N-m (5.5 ft-lb).
Important:
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.
