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 Personal protective equipment IMPORTANT! IMPORTANT! The machine is only designed for cutting branches and twigs. Incorrect or careless use of a hedge trimmer can turn it into a dangerous tool that can cause serious or even fatal injury. It is extremely important that you read and understand the contents of this operator’s manual. Never use a machine that has been modified in any way from its original specification.
GENERAL SAFETY PRECAUTIONS FIRST AID KIT Always have a first aid kit nearby. Make sure the throttle control is locked at the idle setting when the throttle lockout is released. Machine′s safety equipment 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 Hand guard Muffler The hand guard prevents hands from coming into contact with the moving blades, for example, if the operator loses grip on the front handle. The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A muffler fitted with a catalytic converter is also designed to reduce harmful exhaust gases. Check that the hand guard is fitted correctly.
GENERAL SAFETY PRECAUTIONS ! ! WARNING! The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler. Assembly of the catcher (accessory) Loosen the nuts on top of the bar. Align the bolts in the holes on the catcher and fit the bolts. Adjust the blades’ contact pressure according to the instructions under the heading Blades.
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 • • Inspect the working area. Remove any objects that could be thrown out. Check the cutting attachment. Never use blades that are dull, cracked or damaged. Starting and stopping ! WARNING! The complete clutch cover and gear housing must be fitted before the machine is started, otherwise the clutch may come loose and cause personal injury. Always move the machine about 3 metres from the refuelling position before starting. Place the machine on a firm surface.
STARTING AND STOPPING 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. Push the choke control back to its original position as soon as the engine fires, and continue trying to start until the engine starts.
WORKING TECHNIQUES General working instructions IMPORTANT! • Keep in mind that the operator is responsible for accidents or hazards occuring to other people or their property. Safety instructions while working This section takes up the basic safety precautions for working with a hedge trimmer. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. • Always ensure you have a safe and stable working position.
WORKING TECHNIQUES Safety instructions after completing work • The transport guard should always be fitted to the cutting attachment when the machine is not in use. • Make sure the cutting attachment has stopped before cleaning, carrying out repairs or an inspection. Disconnect the HT lead from the spark plug. • Always wear heavy-duty gloves when repairing the cutting attachment. This is extremely sharp and can easily cause cuts. • Store the machine out of reach of children.
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 with the idle adjustment screw T, if adjustment is necessary. First turn the idle adjustment screw T clockwise until the blades start to move. Then turn the idle adjustment screw T anticlockwise until the blades stop. The idle speed is correctly adjusted when the engine runs smoothly in every position. There should also be a clear margin to the speed at which the blades start to move.
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: 1 2 34 • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts • Excessive fuel consumption. Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.
MAINTENANCE Gear housing There is a grease nipple and a plug for filling lubricant on the gear housing. Use a grease gun to fill with grease. This should be done after every 60 working hours. Use Husqvarna’s special grease, no. 503 98 96-01. CAUTION! The gear housing must not be filled completely with grease. The grease expands as the machine heats up during operation. If the gear housing was completely filled with grease it could damage the seals and lead to leakage of grease.
