CLEANINg ThE EXhAUST PORT Depending on the type of fuel used, the type and amount of lubricant used, and/or your operating conditions, the exhaust port may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, you may need to remove these deposits to restore performance. We highly recommend that only qualified service technicians perform this service. SPARK ARRESTOR The spark arrestor must be replaced every 50 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 your model.

For proper performance and long life, keep air filter screen clean. • Remove the air filter cover by pushing down on the latch with your thumb while gently pulling on the cover. • Brush the air filter screen lightly to clean. • Replace the air filter cover by inserting the tabs on the bottom of the cover into the slots on the air filter base; push the cover up until it latches securely in place. FUEL CAP WARNINg: A leaking fuel cap is a fire hazard and must be replaced immediately. Failure to do so may result in serious injury. The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine performance. If performance improves when the fuel cap is loosened, check valve may be faulty or filter clogged. Replace fuel cap if required. SPARK PLUg This engine uses a Champion RCJ6Y or equivalent spark plug with .025 in. electrode gap. Use an exact replacement and replace annually, or more frequently if necessary.

Remove spark plug. Reattach the spark plug cap and lay spark plug on metal cylinder. Pull the starter rope and watch for spark at spark plug tip. If there is no spark, repeat test with a new spark plug. Push primer bulb until bulb is full of fuel. If bulb does not fill, primary fuel delivery system is blocked. Contact a servicing dealer. If primer bulb fills, engine may be flooded, proceed to next item. Remove spark plug, turn trimmer so spark plug hole is aimed at the ground.
