Page 6: General Safety Preca Utions
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 7: 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 8 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 9: 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 will 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 10: Right Hand Guard
GENERAL SAFETY PRECAUTIONS Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle. Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. -
Page 11: Cutting Equipment
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 12: Sharpening Your Chain And Adjusting Depth Gauge Setting
GENERAL SAFETY PRECAUTIONS • Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. • Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links. - Page 13 GENERAL SAFETY PRECAUTIONS Sharpening cutting teeth To sharpen cutting teeth you will need a round file and a file gauge. See instructions under the heading Technical data for information on the size of file and gauge that are recommended for the chain fitted to your chain saw. •...

Page 14: Tensioning The Chain
GENERAL SAFETY PRECAUTIONS Tensioning the chain WARNING! A slack chain may jump off and cause serious or even fatal injury. The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack. - Page 15 GENERAL SAFETY PRECAUTIONS Checking chain lubrication • 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. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.
- Page 16 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 17: Assembly
Fitting the bar and chain 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. Remove the bar nuts and remove the clutch cover (chain brake). -
Page 18: 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, either Aspen two-stroke fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburettor adjustment may be necessary when changing the type of fuel (see the instructions under the heading Carburettor). -
Page 19: Fuelling
Chain oil • We recommend the use of special oil (chain oil) with good adhesion characteristics. • Never use waste oil. This results in damage to the oil pump, the bar and the chain. • It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. -
Page 20: Transport And Storage
Transport and storage • Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked flames from electrical equipment, electric motors, relays/switches, boilers and the like. • Always store fuel in an approved container designed for that purpose. -
Page 21: 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 22: Starting And Stopping
achieved by quickly disengaging the throttle lock. This prevents unnecessary wear to the clutch, clutch drum and brake band. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. -
Page 23: 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 24: General Rules
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. Switch the engine off before leaving your chain saw for any length of time. -
Page 25: Basic Cutting Technique
the saw chain is jamming, the saw may be pushed back at you. Unless the user resists this pushing force there is a risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree, which will lead to a kickback. -
Page 26: Tree Felling Technique
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 of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury. - Page 27 Felling direction The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely. Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally.
- Page 28 Next make the bottom cut so that it finishes exactly at the end of the top cut. The directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45°. The line where the two cuts meet is called the directional cut line.

Page 29: Freeing A Tree That Has Fallen Badly
Freeing a tree that has fallen badly Freeing a ”trapped tree” It is very dangerous to remove a trapped tree and there is high accident risk. Never try to fell the tree that is trapped. Never work in the risk zone of the hanging trapped tree. The safest method is to use a winch. -
Page 30: 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. -
