These procedures should also be a part of any seasonal tune-up. NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these procedures take your unit to any non-road engine repair establishment, individual or authorized service dealer. To prevent serious WARNING: injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start. AIR FILTER MAINTENANCE NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by any non-road engine repair establishment, individual or authorized service dealer. In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance or general lack of acceleration, this service may be required. If you feel your engine is in need of this inspection, refer service to any non-road engine repair establishment, individual or authorized service dealer for repair. DO NOT attempt to perform this process yourself as engine damage may result from contaminants involved in the cleaning process for the port. To avoid serious WARNING: personal injury, always turn your unit off and allow it to cool before you clean or service it. Clean and re-oil the air filter every 10 hours of operation. It is an important item to maintain. Failure to maintain your air filter properly can result in poor performance or can cause permanent damage to your engine. 1. Remove the carburetor/air filter cover by pushing on the tab, located to the right of the cover (Fig. 7). 2. Swing the air filter cover open. It will swing on the hinges to the left of the cover (Fig. 8). 3. Remove the air filter (Fig. 8). 4. Wash the filter in detergent and water. Rinse the filter thoroughly and allow it to dry (Fig. 9). 5. Apply enough clean SAE 30 motor oil to lightly coat the filter (Fig. 10). 6. Squeeze the filter to spread and remove excess oil (Fig. 11). 7. Reinstall the filter and close the air filter cover (Fig. 7).
