MAINTENANCE IDLE SPEED ADJUSTMENT See Figure 15. WARNING: The blade/cutting head will move when adjusting the idle speed. Wear all protective clothing and keep all bystanders, children, and pets at least 50 ft. away. Make adjustments with the unit supported by hand so that the blade/cutting head does not contact the ground or any object. Keep all parts of your body away from the blade/ cutting head and muffler. Failure to follow these instructions could result in serious personal injury. If the cutting attachment turns at idle, the idle speed screw needs adjusting on the engine. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cutting attachment movement. If the cutting attachment still moves at idle speed, contact a service dealer for adjustment and discontinue use until the repair is made. WARNING: The cutting attachment should never turn at idle. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cutting attachment, or contact a service dealer for adjustment and discontinue use until the repair is made. Serious personal injury could result from the cutting attachment turning at idle. CLEANING THE AIR FILTER SCREEN See Figure 16. For proper performance and long life, keep air filter screen clean.  Remove the air filter cover by pushing down on the latches while gently pulling off 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: Check for fuel leaks. A leaking fuel cap is a fire hazard and must be replaced immediately. If you find any leaks, correct the problem before using the product. Failure to do so could result in a fire that could cause serious personal 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 RCJ-6Y or NGK BPMR7A spark plug with .025 in. electrode gap. Use an exact replacement and replace annually. STORING THE TRIMMER  Clean all foreign material from the trimmer. Store it in a well-ventilated place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts.  Abide by all Federal and local regulations for the safe storage and handling of gasoline. WHEN STORING 1 MONTH OR LONGER:  Drain all fuel from tank into a container approved for gasoline. Run engine until it stops. HIGH ALTITUDE ENGINE OPERATION Please have an authorized service center adjust this engine if it is to be run above 2000 feet. Failure to do so may result in poor engine performance and increased emissions. An engine adjusted for high altitudes can not be run at 2000 feet or lower. In doing so, the engine will overheat and cause serious engine damage. Please have an authorized service center restore high altitude modified engines to the original factory specification before operating below 2000 feet. Page 11 - English
