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 waterpowered 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. • Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping. • Do not use the chain saw until sufficient chain oil has reached the chain. See instructions under the heading Lubricating cutting equipment.
GENERAL SAFETY PRECAUTIONS Always use common sense It is not possible to cover every conceivable situation you can face when using a chain saw. Always exercise care and use your common sense. Avoid all situations which you consider to be beyond your capability. If you still feel uncertain about operating procedures after reading these instructions, you should consult an expert before continuing. Do not hesitate to contact your dealer or us if you have any questions about the use of the chain saw.
GENERAL SAFETY PRECAUTIONS Take care when using your saw and make sure the kickback zone of the bar never touches any object. • 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.
GENERAL SAFETY PRECAUTIONS If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake is designed to be activated manually by the movement of your left hand. • 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.
GENERAL SAFETY PRECAUTIONS Vibration damping system Muffler Your machine is equipped with a vibration damping system that is designed to reduce 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 recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. ! WARNING! Any contact with a rotating saw chain can cause extremely serious injuries. Some terms that describe the bar and chain • Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.
GENERAL SAFETY PRECAUTIONS • Drive link width (mm/inches) • Number of drive links. 3 File position 4 Round file diameter 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. Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • • Never use a blunt chain.
GENERAL SAFETY PRECAUTIONS • File all the teeth to the same length. When the length of the cutting teeth is reduced to 0.16 inch (4 mm) 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 455e Rancher • Lubricating cutting equipment ! Release the knob by folding it out. WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. Chain oil Chain oil must demonstrate good adhesion to the chain and also maintain its flow characteristics regardless of whether it is warm summer or cold winter weather. • Turn the knob anti clockwise to loosen the bar cover.
GENERAL SAFETY PRECAUTIONS Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface. Chain drive sprocket The clutch drum is fitted with one of the following drive sprockets: A Spur sprocket (the chain sprocket is welded on the drum) B Rim sprocket (replaceable) If the chain lubrication is not working: • • Check that the oil channel in the bar is not obstructed. Clean if necessary.
GENERAL SAFETY PRECAUTIONS Bar ! 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. WARNING! Most chain saw accidents happen when the chain touches the operator. Wear personal protective equipment. See instructions under the heading Personal protective equipment. Do not tackle any job that you feel you are not adequately trained for.
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. 455 Rancher, 460 Rancher Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.
ASSEMBLY Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar. Make sure that the edges of the cutting links are facing forward on the top edge of the bar. Fit the clutch cover and locate the chain adjuster pin in the hole in the bar. Check that the drive links of the chain fit correctly over the drive sprocket and that the chain is correctly located in the groove in the bar.
FUEL HANDLING Fuel Gasoline, litre Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke 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. WARNING! Always ensure there is adequate ventilation when handling fuel.
FUEL HANDLING • • • It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. In temperatures below 32°F (0°C) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. Contact your service agent when choosing chain oil. • Move the machine at least 10 ft (3 m) from the refuelling point before starting it.
STARTING AND STOPPING Starting and stopping ! WARNING! Note the following before starting: Decompression valve (C): Press the valve to reduce the pressure in the cylinder and make starting easier. You should always use the decompression valve when starting the machine. Once the machine has started the valve will automatically return to its original setting. The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting.
STARTING AND STOPPING As the chain brake is still activated the engine must return to idling speed as soon as possible by disengaging the throttle latch in order to avoid unnecessery wear on the clutch assembly. Push in the choke control as soon as the engine fires and make repeated starting attempts. Immediately press and release the throttle when the engine starts. That will disengage the throttle latch. • The chain brake should be activated when starting.
WORKING TECHNIQUES Before use: • 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. 4 Check that the stop switch works correctly and is not damaged. 5 Check that all handles are free from oil.
WORKING TECHNIQUES 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards. Fit a guard to the bar before transporting the chain saw or carrying it for any distance. 7 When you put the chain saw on the ground, lock the saw chain using the chain brake and ensure you have a constant view of the machine. Switch the engine off before leaving your chain saw for any length of time.
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 with a pushing chain. 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. • • Cutting from above = Cutting with a pulling chain. Cutting from below = Cutting with pushing chain. Cutting with a pushing chain increases the risk of kickback.
WORKING TECHNIQUES The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw. Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen. Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece.
WORKING TECHNIQUES Finish by cutting from below so that the two cuts meet. 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 beyond your experience level! You may find you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you first intended.
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 1.5-2 inches (3-5 cm) above the bottom directional cut. Felling is done using three cuts.
WORKING TECHNIQUES 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. The safest method is to use a winch. • Tractor-mounted • Portable Cutting trees and branches that are in tension There are methods for felling trees with a diameter larger than the bar length.
WORKING TECHNIQUES How to avoid kickback ! WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.
MAINTENANCE General 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. Carburetor adjustment Due to existing environmental and emissions legislation your chain saw is equipped with movement limiters on the carburetor adjuster screws. These limit the adjustment possibilities to a maximum of a 1/2 turn.
MAINTENANCE To adjust the carburetor correctly you should contact a mechanic with access to a rev counter. CAUTION! As the spark is cut off, the rev counter does not show speeds higher than 13600 rpm. Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover. Correctly adjusted carburetor When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed.
MAINTENANCE Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately. Chain catcher Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. Throttle lockout • Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
MAINTENANCE Stop switch use a muffler if the spark arrestor screen is missing or defective. Start the engine and make sure the engine stops when you move the stop switch to the stop setting. The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material. Muffler Starter ! Never use a machine that has a faulty muffler.
MAINTENANCE • Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley. Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the center of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord.
MAINTENANCE Spark plug When lubricating, remove the clutch cover by loosening the two bar nuts. Lay the saw on its side with the clutch drum upwards. Lubrication involves engine oil dripping into the centre of the clutch drum as it rotates. 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.
MAINTENANCE 5 Cylinder cover (directs cold air over the cylinder). Temperature 0°°C (32°°F) or colder: The cylinder cover is designed so it can be adjusted for running in cold weather, so that preheated air from the cylinder can pass into the carburetor space preventing icing of the air filter, etc. Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
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 Weekly maintenance Monthly maintenance Clean the outside of the machine. 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 0.024 inch (0.6 mm) remains at the most worn point.
