• Ensure that the handle and safety functions are in order. Never use a machine that lacks a part or has been modified outside of the specifications. Start and stop Start WARNING! ! The gearbox and clutch drum must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury. Always move the hedge trimmer about 3 metres from the filling position before starting. Place the machine on a flat surface. Bear in mind that the blades start to move when the engine is started. Make sure the blades cannot come into contact with any object. Make sure that no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury. Cold engine IGNITION: Set the stop switch to the start position. CHOKE: Set the choke control in the choke position (A). The choke position is also the automatic start throttle position. AIR PURGE: Press the air purge diaphragm repeatedly until fuel begins to fill the diaphragm. The diaphragm need not be completely filled. A Warm engine IGNITION: Set the stop switch to the start position. CHOKE: Set the choke control in the choke position and then back again to its original position (B) In this way only the start throttle is applied with no choke. AIR PURGE: Press the air purge diaphragm repeatedly until fuel begins to fill the diaphragm. The diaphragm need not be completely filled. Press the machine body against the ground using your left hand (NOTE! Do not use your foot). Grip the starter handle with your right hand and slowly pull the starter cord out until you feel some resistance, (the starter hooks grip) now quickly and powerfully pull the cord. Immediately press the choke control in when the engine fires and repeat until the engine starts. When the engine starts, quickly apply full throttle and the start throttle will automatically disengage. NOTE! Do not pull the starter cord out completely and do not release the starter cord from the fully extended position. This can damage the hedge trimmer. Stop The engine is stopped by switching the ignition off using the stop switch. B English – 13 MAINTENANCE Carburettor Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburettor for optimum operating conditions. WARNING! ! The complete clutch cover and gear must be fitted before the machine is started, otherwise the clutch may come loose and cause injury. Operation • The carburettor governs the engine’s speed via the throttle. Air/fuel is mixed in the carburettor. The air/fuel mixture is adjustable. To take advantage of the engine’s optimal output the adjustment must be correct. • The setting of the carburettor means that the engine is adapted to local conditions, for example, the climate, altitude, petrol and the type of 2-stroke oil. H L T • The carburettor is equipped with three adjustment possibilities: H = High speed needle L = Low speed needle T = Idle speed adjuster screw • The fuel quantity in relation to the air flow permitted by the throttle opening is adjusted using the L and H-needles. Turning the needles clockwise gives a leaner fuel mixture (less fuel) and turning them anti-clockwise gives a richer fuel mixture (more fuel). A leaner mixture gives high revs while a richer mixture give less revs. • The T-screw regulates the position of the throttle while the engine is idling. Turning the screw clockwise gives a higher idling speed while turning it anti-clockwise gives a lower idling speed. Basic setting • The carburettor is set to its basic setting when test run at the factory. The basic setting is richer than the optimal setting and should be kept during the machine’s first working hours. Thereafter the carburettor should be finely adjusted. Fine adjustment should be carried out by a skilled technician. NOTE! If the cutting attachment rotates/moves while the engine is idling the T-screw should be turned anti-clockwise until the cutting attachment stops. Recommended idling speed is 2 700 rpm. Recommended max. speed: See “technical data”. WARNING! ! If the idling speed cannot be adjusted so that the cutting attachment stops, contact your service workshop. Do not use the machine until it has been correctly adjusted or repaired. Adjusting the idle speed, T Adjust the idling speed with the screw T, if it is necessary to readjust. First turn the idle speed adjusting screw T clockwise until the cutting attachment starts to rotate/ move. Then turn, counter-clockwise until the cutting attachment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the cutting attachment starts to move...
