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 Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant.

GENERAL SAFETY PRECAUTIONS Important IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or forestry clearing. The only accessories you can operate with this engine unit are the cutting attachments we recommend in the chapter on Technical data. ! 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.
GENERAL SAFETY PRECAUTIONS Machine′s safety equipment Press the throttle lockout and make sure it returns to its original position when you release it. This section describes the machine′s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the ”What is what?” section to locate where this equipment is positioned on your machine.
GENERAL SAFETY PRECAUTIONS Cutting attachment guard This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment. Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.
GENERAL SAFETY PRECAUTIONS For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment. Never use a machine that has a faulty muffler. Regularly check that the muffler is securely attached to the machine. If the muffler on your machine is fitted with a spark arrestor screen this must be cleaned regularly.
GENERAL SAFETY PRECAUTIONS Cutting equipment General rules This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of blade thrust. • Obtain maximum cutting performance. • Extend the life of cutting equipment. Only use cutting attachments with the guards we recommend! See the chapter on Technical data. IMPORTANT! Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
GENERAL SAFETY PRECAUTIONS Sharpening the saw blade Trimmer head IMPORTANT! • A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and clearing saw. • • Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. See the cutting attachment packaging for correct sharpening instructions. • Only use the recommended trimmer heads and trimmer cords.
ASSEMBLY Assembling the handlebar and throttle CAUTION! Some models have the throttle handle fitted at the factory. • Remove the screw at the rear of the throttle handle. • Slide the throttle handle onto the right side of the handlebar, (see diagram). • Align the screw hole in the throttle handle with the hole in the handlebar. • Refit the screw in the hole in the rear of the throttle handle. • Screw the screw through the handle and handlebar. Tighten it.
ASSEMBLY Assembling the cutting equipment ! • Insert the locking pin (C) in the hole to lock the shaft. • Position the blade (D) with the drive disk (B). Make sure that the blade is centered by fitting it to the guide on the drive disk. • Fit the support flange (F) on the output shaft so that it rests against the blade.
ASSEMBLY Fitting the blade guard and saw blade guard as possible. To tighten the nut, turn the spanner in the opposite direction to the direction of rotation (Caution! left-hand thread). CAUTION! Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data. 343F, 345FX, 345FXT • The blade guard (A) is fitted using 4 screws (L) as shown. L When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade.
ASSEMBLY • Tighten the trimmer head to a torque of 35-50 Nm (3.5-5 kpm). • To dismantle, follow the instructions in the reverse order. Fitting other guards and cutting attachments Standard harness Safety release At the front is an easily accessible, quick release. Use this if the engine catches fire or in any other emergency situation that requires you to free yourself from the machine and harness. Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades.
ASSEMBLY Triobalance harness 6 The elastic strap (B) can be tightened to transfer more load from the shoulder straps to the hip strap. Safety release A Push down the red release lever to release the machine from the harness. B Correct balance 1 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 Gasoline Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilled 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.
FUEL HANDLING Fueling Mixing • Always mix the gasoline and oil in a clean container intended for fuel. • Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. • ! 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 PART THROTTLE FUNCTION (RX): It is possible to set the engine for part throttle operation using the dial on the side of the throttle handle. Turn the dial up to decrease the part throttle rpm. Turn the dial down to increase the part throttle rpm. When you have set the part throttle rpm you will feel increased resistance when you press the throttle trigger. This increased resistance makes it easier to maintain a constant part throttle setting.
WORKING TECHNIQUES General working instructions 6 Keep a good balance and a firm foothold. 7 Always hold the machine with both hands. Hold the machine on the right side of your body. IMPORTANT! This section describes the basic safety precautions for working with clearing saws 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. Avoid all usage which you consider to be beyond your capability.
WORKING TECHNIQUES ! WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning. • You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind conditions, so that cleared stems fall in the cleared area of the stand.
WORKING TECHNIQUES • 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. Then finish cutting the stem from the other side. Adjust the cutting pressure to match the size of the stem and the hardness of the wood. Small stems require more pressure, while large stems require less pressure.
WORKING TECHNIQUES Grass trimming with a trimmer head Sweeping • The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro. • When cutting and sweeping you should use full throttle to obtain the best results. Trimming • Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace.
MAINTENANCE Carburetor Basic setting 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 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 anticlockwise 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.
MAINTENANCE 4 If the start throttle speed is too high, turn the adjuster screw A anticlockwise until the cutting attachment stops. Then turn adjuster screw A clockwise a further 1/2 turn. Muffler Cooling system To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: 4 CAUTION! Some mufflers are fitted with a catalytic converter. See chapter on Technical data to see whether your machine is fitted with a catalytic converter.
MAINTENANCE An oiled foam plastic filter (available as an accessory) must be used if the machine is operated in extremely dusty conditions. See instructions under the heading Oiling the air filter. Drive shaft The drive shaft must be greased every three months during full-time use. Contact your dealer if you are uncertain about the procedure. Spark plug Oiling the air filter The spark plug condition is influenced by: Always use HUSQVARNA filter oil, art. no. 531 00 92-48.
MAINTENANCE Temperature 0°°C (32°°F) or colder: The air filter holder is prepared so it can be changed for use in the cold. Remove the air filter cover and air filter. Turn the winter cover anticlockwise using a screwdriver so that the preheated air from the engine can pass inside the carburettor compartment and prevent, for example, the air filter from icing up (see figure).
