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 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 Before using a new chain saw • Please read this manual carefully. • Check that the cutting equipment is correctly fitted and adjusted. See instructions under the heading Assembly. Important IMPORTANT! The machine is only designed for cutting wood. • Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping. You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data.
GENERAL SAFETY PRECAUTIONS chain saw usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available. • Fire Extinguisher and Shovel Generally clothes should be close-fitting without restricting your freedom of movement. IMPORTANT! Sparks can come from the muffler, the bar and chain or other sources. Always have fire extinguishing tools available if you should need them. Help prevent forest fires.
GENERAL SAFETY PRECAUTIONS • The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism. • The brake is applied when the front hand guard (B) is pushed forwards. • • • • • To release the chain brake pull the front hand guard backwards, towards the front handle. • Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake.
GENERAL SAFETY PRECAUTIONS • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action. Throttle lockout The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e.
GENERAL SAFETY PRECAUTIONS Vibration damping system Muffler Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. ! The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit.
GENERAL SAFETY PRECAUTIONS General rules Chain • A chain is made up of a number of links, which are available in standard and low-kickback versions. Only use cutting equipment recommended by us! See instructions under the heading Technical data. IMPORTANT! No saw chain design eliminates the danger of kickback. • Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.
GENERAL SAFETY PRECAUTIONS Chain • • 3 File position 4 Round file diameter Chain pitch (inches) Drive link width (mm/inches) It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain. • Number of drive links.
GENERAL SAFETY PRECAUTIONS • File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (0.16") the chain is worn out and should be replaced. Tensioning the chain ! General advice on adjusting depth gauge setting • When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be filed down to achieve the recommended depth gauge setting.
GENERAL SAFETY PRECAUTIONS Lubricating cutting equipment Checking chain lubrication • ! WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. Check the chain lubrication each time you refuel. See instructions under the heading Lubricating the bar tip sprocket. Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away.
GENERAL SAFETY PRECAUTIONS Chain drive sprocket Bar The clutch drum is fitted with one of the following drive sprockets: Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a file if necessary. • Whether the groove in the bar has become badly worn. Replace the bar if necessary. • Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain.
ASSEMBLY Fitting the bar and chain ! Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain should be tensioned until it does not sag from the underside of the bar. WARNING! Always wear gloves, when working with the chain. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.
FUEL HANDLING Fuel Mixing ratio 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. ! 1:50 (2%) with HUSQVARNA two-stroke oil.
FUEL HANDLING Fuelling ! Fuel safety • Never refuel the machine while the engine is running. • Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-stroke oil). • Move the machine at least 3 m from the refuelling point before starting it. Tighten the fuel cap carefully after refuelling. • Never start the machine: Always move the machine away from the refuelling area before starting. 1 If you have spilt fuel or chain oil on the machine.
STARTING AND STOPPING Starting and stopping ! Warm engine WARNING! Note the following before starting: The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting. Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries. Use the same procedure as for starting a cold engine but without setting the choke control in the choke position.
STARTING AND STOPPING Note! Reactivate the chain brake by pushing the front hand guard back towards the front handle. The chain saw is now ready for use. ! • • Always hold the saw with both hands. The right hand should be on the rear handle, and the left hand on the front handle. All people, whether right or left handed, should use this grip. Use a firm grip with thumbs and fingers encircling the chain saw handles.
WORKING TECHNIQUES Before use: Basic safety rules 1 Look around you: • To ensure that people, animals or other things cannot affect your control of the machine. • To make sure that none of the above might come within reach of your saw or be injured by falling trees. , 1 Check that the chain brake works correctly and is not damaged. 2 Check that the rear right hand guard is not damaged. 3 Check that the throttle lockout works correctly and is not damaged.
WORKING TECHNIQUES 5 Take great care when cutting a tree that is in tension. A tree that is in tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury. 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake.
WORKING TECHNIQUES 7 Take great care when you cut with the top edge of the bar, i.e. when cutting from the underside of the object. This is known as cutting on the push stroke. The chain tries to push the chain saw back towards the user. If the saw chain is jamming, the saw may be pushed back at you. Terms Cutting = General term for cutting through wood. Limbing = Cutting branches off a felled tree. Splitting = When the object you are cutting breaks off before the cut is complete.
WORKING TECHNIQUES Limbing When limbing thick branches you should use the same approach as for cutting. If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log. Cut difficult branches piece by piece. 1 2 3 The log is supported at one end. There is a high risk that it will split. Cutting ! Turn the log and finish the cut from the opposite side. WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together.
WORKING TECHNIQUES Tree felling technique IMPORTANT! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task that you feel unsure of! The main point to avoid is letting the tree fall onto another tree. It is very dangerous to remove a trapped tree and there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.
WORKING TECHNIQUES Felling ! Felling cut WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw! The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke. Make the felling cut about 3-5 cm (1.5-2 inches) above the bottom directional cut. Felling is done using three cuts.
WORKING TECHNIQUES When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar. Never work in the risk zone of the hanging trapped tree. We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to find out which lengths of bar are recommended for your saw.
WORKING TECHNIQUES If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep. Kickback only occurs if the kickback zone of the bar touches an object. Continue to cut deeper until tree/limb bends and tension is released. Limbing Cut tree/limb from outside the bend, after tension has been released. How to avoid kickback ! WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user.
MAINTENANCE General • The carburettor has three adjustment controls: - L = Low speed jet The user must only carry out the maintenance and service work described in this manual. - H = High speed jet - T = Idle adjustment screw IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer). H T Carburettor adjustment The carburettor can be designed in different ways, depending on existing environmental and emissions legislation.
MAINTENANCE Low speed jet L Carburettor without movement limiters Turn the low speed jet L clockwise until it stops. If the engine accelerates poorly or idles unevenly, turn the low speed jet L anticlockwise until good acceleration and idling are achieved. H CAUTION! If the chain rotates while idling the T-screw must be turned anti-clockwise until the chain stops. L Fine adjustment of the idle speed T Adjust the idle speed with the T-screw.
MAINTENANCE Fine adjustment High speed jet H When the machine has been ”run-in” the carburettor should be finely adjusted. The fine adjustment should be carried out by a qualified person. First adjust the L-jet, then the idling screw T and then the H-jet. • The recommended engine speeds are as follows: Max. fast idle speed, rpm Idle speed, rpm 385XP 12500 2700 390XP 13500 2700 The high speed jet H influences the power and engine speed of the machine.
MAINTENANCE Checking, maintaining and servicing chain saw safety equipment Note! All service and repair work on the machine demands special training. This is especially true of the machine’s safety equipment. If your machine fails any of the checks described below we recommend that you take it to your service workshop. Checking the inertia brake release Place the chain saw, with the engine switched off, on a stump or other stable surface.
MAINTENANCE Throttle lockout Right hand guard • Make sure the throttle control is locked at the idle setting when the throttle lockout is released. Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. • Press the throttle lockout and make sure it returns to its original position when you release it. Vibration damping system Regularly check the vibration damping units for cracks or deformation.
MAINTENANCE Muffler Starter ! Never use a machine that has a faulty muffler. WARNING! When the recoil spring is wound up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury. Care must be exercised when replacing the return spring or the starter cord. Wear protective glasses and protective gloves. Changing a broken or worn starter cord Regularly check that the muffler is securely attached to the machine.
MAINTENANCE Tensioning the recoil spring • Air filter Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. Note! Check that the pulley can be turned at least a further 1/2 turn when the starter cord is pulled all the way out. 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. • Excessive fuel consumption.
MAINTENANCE Lubricating the bar tip sprocket Adjustment of the oil pump Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.
MAINTENANCE ”Air Injection” centrifugal cleaning Heated handles Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan. (385XPG, 390XPG) On models with the designation XPG/G, the front as well as the rear handle are equipped with electric heating coils. These are supplied with electricity from a built-in generator on the chain saw.
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. Daily maintenance Clean the outside of the machine. Weekly maintenance Monthly maintenance On chain saws without a catalytic converter, check the cooling system weekly. Check the brake band on the chain brake for wear. Replace when less than 0.6 mm (0,024 inch) remains at the most worn point.
