INTRODUCTION Dear Customer, Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant.

GENERAL SAFETY PRECAUTIONS Important Personal protective equipment IMPORTANT! IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or forestry clearing. A clearing saw, brushcutter or trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual.
GENERAL SAFETY PRECAUTIONS BOOTS Wear boots with steel toe-caps and non-slip sole. control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting. CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants.
GENERAL SAFETY PRECAUTIONS be checked. See instructions under the heading Maintenance. Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. Stop switch Use the stop switch to switch off the engine. Start the engine and make sure the engine stops when you move the stop switch to the stop setting. Cutting attachment guard This guard is intended to prevent loose objects from being thrown towards the operator.
GENERAL SAFETY PRECAUTIONS cutter. Certain harnesses also have a quick release fitted to the support hook. If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.
GENERAL SAFETY PRECAUTIONS should operate the socket spanner when loosening or tightening the nut. 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. ! ! WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released.
GENERAL SAFETY PRECAUTIONS incorrectly sharpened or damaged blade increases the risk of accidents. Sharpening the saw blade • Keep the correct setting on the saw blade! Follow our instructions and use the recommended setting tool. An incorrectly set saw blade increases the risk of jamming and blade thrust, and damage to the saw blade. See the cutting attachment packaging for correct sharpening instructions.
GENERAL SAFETY PRECAUTIONS Trimmer head IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. • Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.
ASSEMBLY Assembling the handlebar and throttle • CAUTION! Some models have the throttle handle fitted at the factory. • The handlebar can easily be turned to fit along the shaft for easier transportation and storage. • Remove the screw at the rear of the throttle handle. • • Slide the throttle handle onto the right side of the handlebar, (see diagram). Loosen the knob. Turn the handlebar clockwise so that the throttle handle rests against the engine. • Now twist the handlebar around the shaft.
ASSEMBLY Fitting the blade guard/ combination guard, grass blade and ball-bearing-mounted support cup • must remain inside the gear housing to lock the drive disk.

Bend the guard around the shaft and tighten it with the bolt (L) on the opposite side of the shaft. Use the locking pin (C).
ASSEMBLY 355RX • Fit the holder (R) and bracket (J) with 2 bolts (H) on the gear housing. • Then fasten the blade guard (A) with 4 bolts (L) in the holder (N). arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut. H J K R L A • Fit the drive disc (B) on the output shaft. • Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing.
ASSEMBLY • locking pin in the groove on the screw head and tighten. See diagram. Fit the drive disc (B) on the output shaft. L M G C F A • Fit the drive disc (B) on the output shaft. H D P B C • Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing. • Insert the locking pin (C) in the hole to lock the shaft. • Place the shredder blade (D) and support flange (F) on the output shaft. • Fit the nut (G).
ASSEMBLY Adjusting the harness and brush cutter ! 2 Tighten the chest strap under your left arm so that it fits closely around your body. 3 Adjust the shoulder strap to distribute the load evenly across your shoulders. Press downwards on the suspension hook to load the harness. 4 Adjust the height of the hanging ring as per the instructions.
ASSEMBLY Adjust the height using the strap on the harness for the support hook. 2 Grass clearing The machine should be supported in a harness when grass clearing so that the cutting equipment is parallel to the ground. Correct balance 1 Forestry clearing The machine is balanced by moving the suspension ring on the machine forwards or backwards. On some models the suspension ring is fixed, however, this will then have a number of holes for the support hook.
FUEL HANDLING Fuel safety Never start the machine: 1 If you have spilt fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilt fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water. 3 If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines. catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture.
FUEL HANDLING Fuelling Mixing • Always mix the petrol and oil in a clean container intended for fuel. • Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. • ! Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank. WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel.
STARTING AND STOPPING Check before starting • Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.
STARTING AND STOPPING Warm engine Stopping Use the same starting procedure as for a cold engine but without setting the choke control in the choke position. Stop the engine by switching off the ignition. 355RX, 355FRM Start throttle: (355FX, 355FXT, 355RX, 355FRM) Set the throttle to the start position by moving the choke control to the choke position and then returning it to its original position.
WORKING TECHNIQUES General working instructions yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury. IMPORTANT! This section describes the basic safety precautions for working with brush cutters and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.
WORKING TECHNIQUES ! WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Working methods ! Stop the engine and cutting equipment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burnt if you touch it.
WORKING TECHNIQUES 3 o’clock and 5 o’clock so that the direction of rotation of the blade pushes the bottom of the tree to the left. conditions, so that cleared stems fall in the cleared area of the stand. • To fell a tree forwards, the bottom of the tree should be pulled backwards. Pull the blade backwards with a quick, firm movement. • Large stems must be cut from two sides. First determine which direction the stem will fall. Make the first cut on the felling side.
WORKING TECHNIQUES Brush cutting with a saw blade • Thin stems and brush are mown down. Work with a sawing movement, swinging sideways. • Try to cut several stems in a single sawing movement. • With groups of hardwood stems, first clear around the group. Start by cutting the stems high up around the outside of the group to avoid jamming. Then cut the stems to the required height. Now try to reach in with the blade and cut from the centre of the group.
WORKING TECHNIQUES • When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head. • The shredder blade must not be used on vegetation with a stem diameter larger than 2 cm. 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.
MAINTENANCE Carburettor Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/ service workshop (who will have a rev counter at their disposal) to adjust your carburettor.
MAINTENANCE 3 If the start throttle speed is too low (below 4000 rpm), turn the adjuster screw A clockwise until the cutting attachment starts to rotate. Then turn A clockwise a further 1/2 turn. 4 If the start throttle speed is too high (above 6500 rpm), turn the adjuster screw A anti-clockwise until the cutting attachment stops.
