To ensure that it continues to run at peak performance and to minimize harmful exhaust emissions after the run- --in period, ask your servicing dealer to adjust your carburetor. WARNING: The complete clutch, clutch cover, and shaft must be fitted before the machine is started, otherwise parts could come loose and cause personal injury. Function S The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. S The T- --screw regulates the throttle setting at idle speed. If the T- --screw is turned clockwise this gives a higher idle speed; turning it counterclockwise gives a lower idle speed. Basic setting S The basic carburetor settings are adjusted during testing at the factory. Fine adjustment should be carried out by a skilled technician. CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned counterclockwise until the cutting attachment stops. Rec. idle speed: See “Technical data” section. Recommended max. speed: See “Technical data” section. Fine adjustment of the idle speed- --T Adjust the idle speed using the idle adjustment screw- --T if it is necessary to readjust. First, turn the idle adjustment screw- --T clockwise until the cutting attachment starts to rotate. Then, turn the screw counterclockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate. 545196741 Rev. 2 4/30/09 Idle Speed Screw- --T WARNING:Iftheidlespeedcan- notbeadjustedsothatthecuttingattachmentstops,contactyourser- vicingdealer.Donotusethema- chineuntilithasbeencorrectlyad- justedorrepaired. Unit/Maintenance Safety Disconnect the spark plug before performing maintenance, except carburetor adjustments. Muffler CAUTION! Muffler is fitted with a catalytic converter designed to reduce harmful exhaust gases. The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material. Mufflers are equipped with a special spark arrestor mesh. You should clean the mesh at least once a month. This is best done with a wire brush. If the mesh is damaged it should be replaced. If themeshis frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston. a faulty or loose muffler. Ensure the muffler MufflerboltsCAUTION!NeveruseamachinethathasSparkarrestormeshbolts are tight. English- ---16 MAINTENANCE WARNING: Mufflers fitted with catalytic converters get very hot duringuse andremainsofor some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! WARNING: The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler. WARNING: Bear in mind that: Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! Spark plug The spark plug condition is influenced by: S Incorrect carburetor adjustment. S An incorrect fuel mixture (too much or in correct type of oil). S A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,6 mm. The spark plug should be replaced after about a month in operation or earlier if necessary. 0,6 mm CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: S Carburetor malfunctions S Starting problems S Loss of engine power S Unnecessary wear to engine parts S Excessive fuel consumption Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty. Cleaning the air filter Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry before refitting it. An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced. Beve...
