MAINTENANCE SHC-2620 / S * Replacement is recommended based on the finding of damage or wear during inspection. Air Filter Level 1 Parts Required: Tune Up Kit. 1. Close choke (COLD START position). This prevents dirt from entering the carburetor throat when the air filter is removed. Brush accumulated dirt from air cleaner area. 2. Remove air filter cover. Brush dirt from inside cover. Assure throttle wire retaining clip (A) remains in place as shown when removing or installing air filter cover. 3.
SHC-2620 / S MAINTENANCE Assure air filter is assembled with pleats oriented vertically. Fuel Filter Level 1. Parts Required: Tune Up Kit. Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury may result. 1. Use a clean rag to remove loose dirt from around fuel cap and empty fuel tank. Do not damage fuel line while removing fuel filter from tank or line. 2. Pull the fuel filter from the tank. 3.
MAINTENANCE 4. SHC-2620 / S Install the new filter with the reverse action. Note: Federal EPA regulations require all model year 2012 and later gasoline powered engines produced for sale in the United States to be equipped with a special low permeation fuel supply hose between the carburetor and fuel tank. When servicing model year 2012 and later equipment, only fuel supply hoses certified by EPA can be used to replace the original equipment supply hose.
SHC-2620 / S MAINTENANCE 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.
MAINTENANCE 4. Use brush to remove dirt from the cylinder fins. 5. Remove grass and leaves from the grid (C) between the recoil starter and fuel tank. 6. Assemble components in reverse order. SHC-2620 / S C Exhaust System Spark Arrestor Screen Level 2. Parts Required: Spark Arrestor Screen, Gasket 1. Remove spark plug lead. 2. Remove muffler cover (A). 3.
