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 PROTECTIVE HELMET AND VISOR IMPORTANT! 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. Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination.
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 The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit. Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached. ! WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation.
GENERAL SAFETY PRECAUTIONS Cutting equipment ! This section describes how you can achieve maximum clearing capacity and extend the life of the cutting attachment through correct maintenance and using the right type of cutting attachment. • • Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced. Only use cutting equipment recommended by us! WARNING! Always stop the engine before doing any work on the cutting attachment.
GENERAL SAFETY PRECAUTIONS Chain • • • - Cutting angle - File position - Round file diameter - File depth Saw chain pitch (inches). (The distance between three drive links, divided by two.) Drive link width (mm/inches) Number of drive links. Sharpening your chain and adjusting raker clearance WARNING! The risk of kickback is increased with a badly sharpened chain! ! 1 5 It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge.
GENERAL SAFETY PRECAUTIONS Sharpening cutting teeth • We recommend that you use our raker gauge to achieve the correct clearance and bevel on the raker lip. To sharpen cutting teeth you will need a round file and a file gauge. ! WARNING! The risk of kickback is increased if the raker clearance is too large! Setting the raker clearance • Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difficult to sharpen correctly.
GENERAL SAFETY PRECAUTIONS Tensioning the chain Lubricating cutting equipment ! ! WARNING! A slack chain may jump off and cause serious or even fatal injury. WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. Chain oil • The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
GENERAL SAFETY PRECAUTIONS increase oil consumption, check the level in the oil tank regularly. Turn the adjuster screw clockwise to decrease the oil flow. Chain drive sprocket Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. What to do if lubrication does not work: Bar • Check that the oil channel in the bar is not obstructed. Clean if necessary. Check regularly: • Check that the oil channel in the gear housing is clean. Clean if necessary.
ASSEMBLY Fitting the cutting head • • Fit the cutting head on the shaft so that the screw (A) is aligned with the hole in the shaft as shown. Adjusting the harness • Tighten screw A. • Tighten screw B. B A CAUTION! Make sure that the drive shaft inside the shaft engages with the cut-out in the cutting head. When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly.
ASSEMBLY • Tighten the knob. Assembly of the saw attachment (325P5) Dismantling: Assembly Undo the knob (at least three turns). • Make sure the knob is loose. • Align the cut-out in the upper shaft with the coupling's lock plate on the lower shaft. The parts then lock together. • Tighten the knob. • Push the knob towards the coupling. • Carefully twist the upper shaft to unlock it. • Hold both parts of the shaft and pull the upper shaft out of the coupling.
FUEL HANDLING Fuel safety Fuel Never start the machine: CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and twostroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. 1 If you have spilt fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.
FUEL HANDLING Fuelling Two-stroke oil • For best results and performance use HUSQVARNA twostroke engine oil, which is specially formulated for our aircooled two-stroke engines. • Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). • Never use oil intended for four-stroke engines. • A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters.
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 blunt, cracked or damaged equipment. • Check that the machine is in perfect working order. Check that all nuts and screws are tight. • Make sure the chain is adequately lubricated. See instructions under the heading Lubricating the cutting attachment.
STARTING AND STOPPING 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. 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 • Never work from a ladder, stool or any other raised position that is not fully secured. IMPORTANT! This section takes up the basic safety precautions for working with a pole saw. 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. ! ! WARNING! The machine can cause serious personal injury.
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.
WORKING TECHNIQUES • Never cut through the swelling at the root of the branch as this will slow down healing and increase the risk of fungal attack! • Use the stop at the base of the cutting head to provide support during cutting. This will help prevent the cutting attachment from ”jumping” on the branch. • Make an initial cut on the underside of the branch before cutting through the branch. This will prevent tearing of the bark, which could lead to slow healing and cause permanent damage to the tree.
MAINTENANCE Carburettor 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 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. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.
MAINTENANCE CAUTION! Never use a machine with a defective muffler. ! WARNING! Mufflers fitted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! Cooling system that the electrode gap is 0.5 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.
MAINTENANCE Oiling the air filter 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. Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil.
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.
