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! ! 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. The machine is only designed for cutting branches and twigs. HEARING PROTECTION Never use a machine that has been modified in any way from its original specification. Wear hearing protection that provides adequate noise reduction.
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 Vibration damping system In countries that have a warm and dry climate there is a significant risk of fire. We therefore fit certain mufflers with a spark arrestor mesh. Check whether the muffler on your machine is fitted with this kind of mesh. Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.
GENERAL SAFETY PRECAUTIONS Blades To ensure good cutting results it is important that the contact pressure between the blades is correct. The contact pressure is adjusted by turning the screws on the underside of the bar clockwise as far as they will go. Then turn the screws anticlockwise a 1/4 turn. Lock the screws using the locking nut on the top of the bar. Check that the screws are loose enough to allow the washers under the screw heads to slide sideways.
ASSEMBLY Fitting the hand guard and loop handle Fitting the cutting head (326HDA55) (326HDA55/326HE3) 1 Assemble the hand guard and loop handle by screwing them together. Take care to align the holes in both parts. 1 (326HDA55) 2 Slide the loop handle and hand guard onto the shaft. (326HDA55) 3 Slide the spacer into the slot in the loop handle. 4 Fit the nut and screw. Do not overtighten. It is important that the hedge trimmer is laid on a flat surface when you fit the cutting head.
ASSEMBLY Fitting the impact guard (326HE4) Fit the guard using the three screws and washers. Fit the two short screws in hole A. Tighten the screws to a torque of 4 Nm. After the machine has been in use for around 20 hours, re-tighten the screws to 4 Nm.
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 Choke: Set the choke control in the choke position. • 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. Warm engine Primer bulb: • Check that the machine is in perfect working order. Check that all nuts and screws are tight. • Make sure the gear housing is lubricated correctly. See instructions under the heading Gear housing.
WORKING TECHNIQUES General working instructions Safety instructions while working IMPORTANT! This section takes up the basic safety precautions for working with a hedge trimmer. • Always ensure you have a safe and stable working position. 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 use both hands to hold the machine. Hold the machine at the side of your body.
WORKING TECHNIQUES Safety instructions after completing work Changing the hedge trimmer angle • The transport guard should always be fitted to the cutting attachment when the machine is not in use. (326HE3, 326HE4) • 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.
WORKING TECHNIQUES • Tighten the knob. ! WARNING! Do not hold the cutting head when you adjust the angle. The blades are sharp and you could easily cut yourself. Transport position (326HE4) Once the work has been completed fold the cutting unit back against the shaft to simplify transport and storage of the hedge trimmer. 1 Turn off the engine. 2 Loosen the knob on the shaft (clockwise). 3 Grip the handle on the cutting unit and angle the cutting unit upwards.
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 Correctly adjusted carburettor 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: 4 3 2 1 • 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.
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. Daily maintenance Maintenance Clean the outside of the machine.
