Cleaning the Blower Housing
To ensure proper cooling, clean the grass screen, cooling fins, and other external surfaces
of the engine. Make sure that the cooling shrouds are installed. Torque the blower housing
screws to 4.0 N∙m (35 in-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.
