We highly recommend that only qualified service technicians perform this service. SPARK ARRESTOR The spark arrestor must be cleaned or replaced every 25 hours or yearly to ensure proper performance of the product. Spark arrestors may be in different locations depending on the model purchased. Please contact the nearest service dealer for the location of the spark arrestor for this model. REPLACING AND CLEANING AIR FILTER See Figures 28 - 29. A wet or dirty air filter can affect the way the engine starts, performs, and wears. The air filter should be checked and cleaned after 5 hours of operation. For best performance, the air filter should be replaced once each year. To clean the air filter: .Loosen the knob on the air filter cover. .Remove the cover. .Lift the edge of the air filter carefully and peel it out. .Wash the air filter with warm, soapy water. .Rinse and squeeze to dry. .Reinstall the air filter. NOTE: Make sure the filter is seated properly inside the cover. Installing the filter incorrectly will allow dirt to enter the engine, causing rapid engine wear. ...Reinstall the cover. .Tighten knob to secure. FUEL CAP WARNING: A leaking fuel cap is a fire hazard and must be replaced immediately. The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine perfor- mance. If performance improves when the fuel cap is loos- ened, check valve may be faulty or filter clogged. Replace fuel cap if required.
