Cleaning the Blower Housing
Every 100 hours/Yearly (whichever comes first)
To ensure proper cooling, ensure 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 the cooling
shrouds are installed.
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.
