Section 4
Air Cleaner and Air Intake System
5. When servicing the foam air cleaner element,
clean and check the air cleaner case and outer
cover for damage, distortion, or an improper seal.
Replace any components which are bent or
damaged.
6. Make sure the square metal fitting plate is
properly positioned within the case. See Figure
4-17.
7. Reinstall the outer cover and secure with the two
screws. See Figure 4-16.
NOTE: Do not operate engine without the air cleaner
element; excessive piston and/or cylinder
wear may result.
4.6
Air Intake/Cooling System
To ensure proper cooling, make sure the grass screen,
cooling fins and other external surfaces of the engine
are kept clean at all times.
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), remove the
blower housing and other cooling shrouds. Clean the
cooling fins and external surfaces as necessary. Make
sure the cooling shrouds are reinstalled.
NOTE: 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.
