Cooling System Level 2. Parts Required: None if you are careful.
MAINTENANCE SRM-2620 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 muffler cover (A). 3.
SRM-2620 MAINTENANCE Remove spark plug lead. 2. Remove muffler cover (B). 3. Place piston at Top Dead Center (TDC) to prevent carbon/dirt from entering cylinder. 4.
