Tools required: 25-50 mm (1-2 in.) medium bristle paint brush, 3 mm Hex Wrench, Cross Head Screwdriver, Pointed Wood Stick. Parts Required: None, if you are careful. IMPORTANT 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. Cleaning Grill 1. Remove accumulated debris from intake grill between backpack frame and blower housing. INTAKE GRILL 18 18 1.
