Cooling System
Level 2
To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder fin area.
This flow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching
the cylinder.
• Dust and grass build up on the outside of the cylinder. This
build up insulates the engine and prevents the heat from
leaving.
Removal of cooling passage blockages or cleaning of cooling
fins is considered “Normal Maintenance.” Any failure attributed
to lack of maintenance is not warranted.
1. Remove spark plug lead.
2. Remove air cleaner cover.
3. Remove muffler cover (A).
4. Remove engine cover (B).
DO NOT use a metal scraper to remove dirt from the cylinder fins.
5. Use brush to remove dirt from the cylinder fins.
6. Remove grass and leaves from the grid between the recoil
starter and fuel tank.
7. Assemble components in reverse order.
Parts Required: None if you are careful.
