Facilité d'utilisation
(152 mm) extended beyond the slot. Do not overfill. After winding the string, there should be at least 1/4 in. (6 mm) between the wound string and the outside edge of the spool. nRepeat above step with second string, using the bottom part of spool. Do not overfill. nReplace the spool and the spool retainer. Refer to “Spool Replacement” earlier in this manual. CLEANING THE EXHAUST PORT AND MUFFLER NOTE: Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and muffler 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 recommended that only qualified service technicians perform this service. SPARK ARRESTOR The muffler is equipped with a spark arrestor (screen inside the muffler body). Through normal use, the screen can become dirty and should be periodically cleaned or replaced by an anthorized service dealer. SPOOL SPRING ARROWS ON SPOOL ANCHOR HOLE FIRST STRING Fig. 16 FIRST STRING SLOT Fig. 17 SECOND STRING Fig. 18 SLOT ARROWS ON SPOOL Fig. 19 MAINTENANCE REPLACING AND CLEANING AIR FILTER See Figures 20 - 21. For proper performance and long life, keep air filter clean. nRemove the air filter cover by pushing down on the latch with your thumb while gently pulling on the cover. nRemove the filter, clean it in warm soapy water. Rinse and let dry completely. For best performance, replace annually. nInstall the filter, align tabs, push in, and make sure the latch snaps and latches into place. 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 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 NGK # BPMR7A spark plug with .025 in. (0.63 mm) electrode gap. Use an exact replacement and replace annually, or more frequently if necessary. STORING THE TRIMMER (1 MONTH OR LONGER) nDrain all fuel from tank into a container approved for gasoline. Run engine until it stops. nClean 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. nAbide by all Federal and local regulations for the safe storage and handling of gasoline. Excess fuel should be used up in other 2-cycle engine powered equipment. STOPABC LATCH PULL COVER TO OPEN Fig. 20 STOP123 FILTER AIR FILTER COVER BACSTOP Fig. 21 TROUBLESHOOTING PROBLEM POSSIBLE CAUSE SOLUTION 1.Check spark. 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. 2.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. 3.Remove spark plug, turn trimmer so spark plug hole is aimed at the ground. Move choke lever to “RUN” (C) position and pull starter cord 10 to 15 times. This will clear excess fuel from engine. Clean and reinstall spark plug. Pull starter three times with choke lever at “RUN”. If engine does not start, move choke lever to “FULL CHOKE” (A) position and repeat normal starting procedure. If engine still fails to start, repeat procedure with a new spark plug. 4.Contact a servicing dealer. Allow engine to completely warm up. If engine does not accelerate after three minutes, contact a servicing dealer. Contact a servicing dealer. 1.Use fresh fuel and the correct 2-cycle oil mix. 2.Clean air filter. Refer to “Replacing and Cleaning Air Filter” earlier in this manual. 3.Contact a servicing dealer. Turn idle speed screw clockwise to increase idle speed. Engine will not start Engine starts but will not accelerate Engine starts but will only run at high speed at half choke Engine does not reach full speed and emits excessive smoke Engine starts, runs, and accelerates but will not idle 1.No spark. 2.No fuel. 3.Engine is flooded. 4.Starter rope pulls harder now than when new. Engine requires approximately three minutes to warm up. Carburetor requires adjustment. 1.Check oil fuel mixture. 2.Air filter is dirty. 3.Spark arrestor screen is dirty. Idle speed screw on carburetor needs adjustment. TROUBLESHOOTING PROBLEM POSSIBLE CAUSE SOLUTION String will not advance when using the EZ Line™ tap advance system Spool retainer hard to turn when using EZ Line™ tap advance system Grass wraps around driveshaft housing and string head Oil drips from muffler 1.String is welded to itself. 2.Not enough string on spool. 3.String is worn too short. 4.String is tangled on spool. 5.Engine speed is too slow.
