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 Charles 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! HEARING PROTECTION Wear hearing protection that provides adequate noise reduction. 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.
GENERAL SAFETY PRECAUTIONS The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest service workshop. Check that the throttle control and throttle lock move freely and that the return springs work properly. IMPORTANT! All servicing and repair work on the machine requires special training.
GENERAL SAFETY PRECAUTIONS Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data. ! 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.
GENERAL SAFETY PRECAUTIONS 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. 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.
GENERAL SAFETY PRECAUTIONS General rules Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Sharpening grass cutters and grass blades • See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut flat file. • Sharpen all edges equally to maintain the balance of the blade. Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended file gauge.
GENERAL SAFETY PRECAUTIONS so, this should be done before filing with a round file. The top edges must be filed down by the same amount for all the teeth. Adjust the blade setting. This should be 1 mm. 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.
ASSEMBLY Assembling the handlebar and throttle Fitting the handlebar (240F, 252RX) (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.
ASSEMBLY Fitting the handlebar Assembling the cutting equipment (265RX) WARNING! ! • 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 Fitting other guards and cutting attachments Spreading the load on your shoulders A well-adjusted harness and machine makes work much easier. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across both shoulders. Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades. Secure the trimmer guard using the 4 screws (L) and the support plate (M) as shown.
ASSEMBLY Adjusting the harness Correct balance 1 1 Tighten the hip strap so that it sits securely. 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. Forestry clearing The machine is balanced by moving the support ring on the machine forwards or backwards.
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 good quality petrol/oil mixture (at least 90 octane).
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 ! 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. • Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.
STARTING AND STOPPING Starting and stopping Cold engine Ignition: Set the stop switch to the start position. Choke: Set the choke control in the choke position. Starting 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. Never twist the starter cord around your hand.
WORKING TECHNIQUES General working instructions IMPORTANT! 5 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 6 Never put the machine down with the engine running unless you have it in clear sight. 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.
WORKING TECHNIQUES Working methods ! WARNING! Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions. Because of the speed of rotation of the blade kickback can occur if you attempt to cut thick stems with this area of the blade. • Before you start clearing, check the clearing area, the type of terrain, the slope of the ground, whether there are stones, hollows etc. • Start at whichever end of the area is easiest, and clear an open space from which to work.
WORKING TECHNIQUES 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. • If the stems are tightly packed, adapt your walking pace to suit. • If the blade jams in a stem, never jerk the machine free. If you do this the blade, bevel gear, shaft or handlebar may be damaged. Release the handles, grip the shaft with both hands and gently pull the machine free.
WORKING TECHNIQUES Grass trimming with a trimmer head Trimming • • • 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.
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 If the mesh is frequently blocked, this can be a sign that the performance of the 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 265RX Air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts.
MAINTENANCE 265RX Bevel gear Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. 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. Ensure that the filter is dry before refitting it. The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
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.
