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 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 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 mesh this must be cleaned regularly. A blocked mesh 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 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 (240R, 250R) • 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. • Unscrew the knob from the handlebar mounting. • Position the handlebar as shown.
ASSEMBLY Fitting the handlebar (265RX) • Fit the left handlebar in the handlebar mounting. • Fit the right handle to the handlebar. • Adjust roughly and tighten the screws slightly. • Now make a final adjustment, with the machine hanging from the harness, to obtain the most comfortable working position. Tighten the screws.
ASSEMBLY • Fit the support flange (F) on the output shaft. Make sure that the blade is centered by fitting it to the guide on the support flange. • Screw the support cup (E) onto the output shaft threads (CAUTION! Left-hand thread). Tighten to a torque of 3550 Nm (3.5-5.0 kpm). Use the socket spanner in the tool kit. Note that the locking pin (C) must remain inside the gear housing to lock the drive disk. Hold the shaft of the socket spanner as close to the blade guard/combination guard as possible.
ASSEMBLY • Tighten the trimmer head to a torque of 35-50 Nm. H Adjusting the harness and clearing saw ! • WARNING! When using a clearing saw it must always be hooked securely to the harness. Otherwise you will be unable to control the clearing saw safely and this can result in injury to yourself or others. Never use a harness with a defective quick release. To dismantle, follow the instructions in the reverse order.
ASSEMBLY 2 Grass clearing 4 Adjust the height of the suspension hook as described in the instructions for the standard harness. (Forestry clearing) 5 If you need to lower the suspension hook, for trimming for example, move the suspension strap (A) to the lower mounting point on the backplate. 6 The elastic strap (B) can be tightened to transfer more load from the shoulder straps to the hip strap.
FUEL HANDLING Fuel safety Petrol 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. CAUTION! Always use a quality petrol/oil mixture at least 90 octane (RON).
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 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.
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 Carburettor 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 High speed jet H (250R, 252RX) 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 265RX The machine is equipped with fixed L and H-needles, in order to ensure that the machine always receives the correct mixture of fuel and air. catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston. 250R/252RX When the engine lacks power or accelerates poorly, proceed as follows: • Check the air filter and replace if necessary.
MAINTENANCE Air filter Oiling the air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption.
MAINTENANCE Spark plug The spark plug condition is influenced by: • Incorrect carburettor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action.
MAINTENANCE Maintenance schedule The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section. The user must only carry out the maintenance and service work described in this Operator’s Manual. More extensive work must be carried out by an authorised service workshop.
