Cleaning The Blower Housing; Fuel System Maintenance; Replacing The In-Line Fuel Filter - Toro 74785 Operator's Manual

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.
