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. -
Page 7: Always Use Common Sense
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. - Page 8 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. • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).

Page 12: Sharpening Your Chain And Adjusting Depth Gauge Setting
GENERAL SAFETY PRECAUTIONS • 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 13: Tensioning The Chain
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. General advice on adjusting depth gauge setting •... -
Page 14: Lubricating Cutting Equipment
GENERAL SAFETY PRECAUTIONS Lubricating cutting equipment 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. - Page 15 GENERAL SAFETY PRECAUTIONS 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) Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive.

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 17: 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... -
Page 18: Fuelling
Fuelling WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke and do not place any hot objects in the vicinity of fuel. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. - Page 19 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.

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. This can damage the machine. Note! Reactivate the chain brake by pushing the front hand guard back towards the front handle. -
Page 21: 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 22: 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 23: 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 24 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 25: Tree Felling Technique
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! 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 26 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 27: Freeing A Tree That Has Fallen Badly
All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed. 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. -
Page 28: How To Avoid Kickback
General advice: Position yourself so that you will be clear of the tree or branch when the tension is released. Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufficient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension. -

Page 30: High Speed Jet H
High speed jet H At the factory the engine is adjusted at sea level. When working at a high altitude or in different weather conditions, temperatures and atmospheric humidity, it may be necessary to make minor adjustments to the high speed jet. CAUTION! If the high speed jet is screwed in too far, it may damage the piston/cylinder. -
Page 31: Throttle Lockout
Checking the inertia brake release Place the chain saw, with the engine switched off, on a stump or other stable surface. Release the front handle and let the saw fall by its own weight, rotating around the rear handle towards the stump. When the bar hits the stump the brake should be applied. -
Page 32: Muffler
Chain catcher Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. Right hand guard Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. Vibration damping system Regularly check the vibration damping units for cracks or deformation. -
Page 33: Starter
Starter 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. -
Page 34: Air Filter
A damaged air filter must always be replaced. A HUSQVARNA chain saw can be equipped with different types of air filter according to working conditions, weather, season, etc. Contact your dealer for advice. -

Bar 18" -24": 3 turns from the closed position. Bar 24" -: 4 turns from the closed position. These recommendations apply to Husqvarna’s chain oil, for other chain oils increase the oil flow by one step. WARNING! The engine must not be running when making adjustments. -
Page 36: Winter Use
Winter use Running problems can occur when using the machine in the cold and snowy conditions caused by: • Too low engine temperature. • Icing of the air filter and carburettor. Special measures are therefore often required: • Preheat the intake air to the carburettor by using the heat from the cylinder. -
