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! HELMET A helmet should be worn if the trees being cleared are taller than 2 m. 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 Machine′s safety equipment Press the throttle lock 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. that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut. Regularly check that the muffler is securely attached to the machine. 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.
GENERAL SAFETY PRECAUTIONS Cutting equipment Saw blades are intended for cutting fibrous types of wood. Grass blades and grass cutters are intended for cutting coarse grass. 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. A trimmer head is intended for trimming grass.
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.

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! lefthand thread).
ASSEMBLY Fitting other guards and cutting attachments (235R) • Spreading the load on your shoulders Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades. CAUTION! Ensure that the guard extension is fitted. 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.
FUEL HANDLING Fuel safety Gasoline 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.
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 Warm engine Stopping Ignition: Set the stop switch to the start position. Choke: Set the throttle to the start position by moving the choke control to the choke position and then returning it to its original position. Stop the engine by switching off the ignition. Primer bulb: Press the air purge repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled.
WORKING TECHNIQUES General working instructions 6 Always hold the machine with both hands. Hold the machine on the right side of your body. 7 Keep the cutting attachment below waist level. 8 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 9 Never put the machine down with the engine running unless you have it in clear sight.
WORKING TECHNIQUES ! WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning. Working methods ! Forestry clearing using a saw blade • The risk of kickback increases with increasing stem size. You should therefore avoid cutting with the area of the blade between 12 o’clock and 3 o’clock. • To fell to the left, the bottom of the tree should be pushed to the right.
WORKING TECHNIQUES • 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. • If the stems are tightly packed, adapt your walking pace to suit. • If the blade jams in a stem, never jerk the machine free.
WORKING TECHNIQUES Clearing • The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord. • The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.
MAINTENANCE Carburetor 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 will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate. If the high speed jet H is set too lean it will result in less power, less performance, poor acceleration and/or damage to the engine. If both the L and H jets are set too rich it will results in acceleration problems or too low a working speed.
MAINTENANCE Cooling system Air filter To keep the working temperature as low as possible the machine is equipped with a cooling system. The air filter must be regularly cleaned to remove dust and dirt in order to avoid: 4 3 2 • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts • Excessive fuel consumption. 1 The cooling system consists of: 1 Air intake on the starter. 2 Fins on the flywheel. 3 Cooling fins on the cylinder.
MAINTENANCE Spark plug The spark plug condition is influenced by: • Incorrect carburetor 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 manual. More extensive work must be carried out by an authorised service workshop.
