SAFETY INSTRUCTIONS Personal protective equipment IMPORTANT! You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment. ! WARNING! Listen out for warning signals or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops.
SAFETY INSTRUCTIONS Vibration damping system Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier. ! ! Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit.
SAFETY INSTRUCTIONS Checking, maintaining and servicing the machine′s safety equipment IMPORTANT! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service.
SAFETY INSTRUCTIONS • Regularly check that the muffler is securely attached to the machine. CAUTION! The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times. ! • The muffler on your machine is equipped with a spark arrestor mesh, this should be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.
SAFETY INSTRUCTIONS ! WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it. • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.
SAFETY INSTRUCTIONS • When storing the machine for long periods the fuel tank must be emptied. Contact your local gas station to find out where to dispose of excess fuel. CAUTION! Do not use the machine unless you are able to call for help in the event of an accident. • The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage. Basic working techniques ! • WARNING! Take care when handling fuel.
SAFETY INSTRUCTIONS Cutting • The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool. • Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

ASSEMBLY Fitting the loop handle Dismantling: • • Undo the knob (at least three turns). • Push the knob towards the coupling. • Carefully twist the lower half of the shaft to unlock it. • Hold both parts of the shaft and pull the lower part of the shaft out of the coupling. Clip the loop handle onto the shaft. Note that the loop handle must be fitted between the arrows on the shaft. • Slide the spacer into the slot in the loop handle. • Fit the nut, knob and screw. Do not overtighten.
ASSEMBLY Fitting the trimmer head ! • Fit the bottom half of the trimmer head (K) to the cover (I) by pressing them together, with the cut-outs on the bottom half aligned with the catches on the cover. • To dismantle, follow the instructions in the reverse order. WARNING! Never use a cutting attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is fitted this can cause serious personal injury.
FUEL HANDLING Fuel When the oil level is low, top up using engine oil to the edge of the oil refill hole. CAUTION! The machine is equipped with a four-stroke engine. Make sure that there is always sufficient oil in the oil tank. ! WARNING! Always ensure there is adequate ventilation when handling fuel. The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.
STARTING AND STOPPING Check before starting Cold engine Ignition: Set the stop switch to the start position. • Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked. Choke: Set the choke control in the choke position. • Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm.
STARTING AND STOPPING Starting ! WARNING! When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately. Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!). Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord.
MAINTENANCE Carburetor ! WARNING! The complete clutch cover and shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury. 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. Function • The carburetor governs the engine’s speed via the throttle control.
MAINTENANCE Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder. Air filter Spark plug The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions • Starting problems The spark plug condition is influenced by: • Loss of engine power • Incorrect carburetor adjustment.
MAINTENANCE Bevel gear The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. Use HUSQVARNA special grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. Weekly maintenance • Check the starter and starter cord. • Clean the carburettor area. • Clean the outside of the spark plug.
