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.

FIRST AID KIT Always have a first aid kit nearby.
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 Never use a machine that has a faulty muffler. Locking nut A locking nut is used to secure some types of cutting attachment. 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. A blocked screen will cause the engine to overheat and may lead to serious damage.
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 • Sharpen all edges equally to maintain the balance of the blade. ! WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type. Adjust the blade setting. This should be 1 mm.
ASSEMBLY Fitting the handlebar (323R) • 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. • Fit the mounting components as shown. • The handle mounting must be fitted between the arrows on the shaft.
ASSEMBLY Assembling and dismantling the two-piece shaft (325RDx) Assembling the cutting equipment WARNING! ! ! Assembly • Loosen the coupling by turning the knob. • Align the tab of the attachment (A) with the arrow on the coupling (B). When fitting the cutting attachment it is extremely important that the raised section on the drive disc/support flange engages correctly in the centre hole of the cutting attachment.
ASSEMBLY • Place the blade (D), support cup (E) and support flange (F) on the output shaft. • Fit the nut (G). The nut must be tightened to a torque of 35-50 Nm (3.5-5 kpm). Use the socket spanner in the tool kit. Hold the shaft of the spanner as close to the blade guard as possible. To tighten the nut, turn the spanner in the opposite direction to the direction of rotation (Caution! left-hand thread). guard as possible.
ASSEMBLY • Fit the nut (G). Tighten the nut to a torque of 35-50 Nm (3.5-5 kpm). Use the socket spanner in the tool kit. Grasp the handle of the spanner as close to the trimmer guard as possible. • To tighten the nut, turn the spanner in the opposite direction to the direction of rotation (Caution! left-hand thread). Adjusting the harness and clearing saw ! WARNING! When using a clearing saw it must always be hooked securely to the harness.
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 CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. Stopping Stop the engine by switching off the ignition. CAUTION! Do not put any part of your body in marked area. Contact can result in burns to the skin, or electrical shock if the spark plug cap has been damaged. Always use gloves. Do not use a machine with damaged spark plug cap.
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 Correctly adjusted carburetor 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.
MAINTENANCE Muffler Cooling system 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. To keep the working temperature as low as possible the machine is equipped with a cooling system. 4 The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator.
MAINTENANCE Air filter Two-piece shaft (325RDx) The air filter must be regularly cleaned to remove dust and dirt in order to avoid: The drive shaft end in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive shaft ends (splined coupling) on models with two-piece shafts will seize if they are not lubricated regularly. • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts • Excessive fuel consumption.
