Cleaning the Blower
Housing
To ensure proper cooling, make sure that 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 that 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, causes engine damage
due to overheating.
