    GENERAL SAFETY PRECA UTIONS Bef ore 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.
  • Page 8: Always Use Common Sense

    GENERAL SAFETY PRECA UTIONS Al ways use common sense It is not possib le 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.
  • Page 9 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.
  • Page 10: Chain Catcher

    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.
  • Page 11: Cutting Equipment

    GENERAL SAFETY PRECAUTIONS Vibration damping system Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier. The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit. The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.
  • Page 12 To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.
  • Page 13: Sharpening Your Chain And Adjusting Depth Gauge Setting

    GENERAL SAFETY PRECAUTIONS • Drive link width (mm/inches) • Number of drive links. Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small.
  • Page 14: Tensioning The 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. General advice on adjusting depth gauge setting •...
  • Page 15: Lubricating Cutting Equipment

    GENERAL SAFETY PRECAUTIONS 455e Rancher • Release the knob by folding it out. • Turn the knob anti clockwise to loosen the bar cover. • Adjust the tension on the chain by turning the wheel down (+) for tighter tension and up (-) to loosen the tension.
  • Page 16 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. If the chain lubrication is not working: •...
  • Page 17 GENERAL SAFETY PRECAUTIONS 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.
  • Page 18: Assembly

    Fitting the bar and chain 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. Remove the bar nuts and remove the clutch cover (chain brake).
  • Page 19 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.
  • Page 20: Fuel Handling

    When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor).
  • Page 21: Fueling

    • 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. •...
  • Page 22: Starting And Stopping

    Starting and stopping 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.
  • Page 23: 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.
  • Page 24: Working Techniques

    Before use: Check that the chain brake works correctly and is not damaged. Check that the rear right hand guard is not damaged. Check that the throttle lockout works correctly and is not damaged. Check that the stop switch works correctly and is not damaged.
  • Page 25: General Rules

    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. 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.
  • Page 26: Basic Cutting Technique

    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.
  • Page 27 The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw. Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. Cutting WARNING! Never attempt to cut logs while they are in a pile or when a couple...
  • Page 28: Tree Felling Technique

    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! Safe distance The safe distance between a tree that is to be felled and anyone else working nearby is at least 2 1/2 tree lengths.
  • Page 29 Felling WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw! Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you finish with the felling cut.
  • Page 30: Freeing A Tree That Has Fallen Badly

    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.
  • Page 31: How To Avoid Kickback

    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.
