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.
GENERAL SAFETY PRECA UTIONS possib le. Your dealer, forestry school or your library can provide information about which training materials and courses are available. Work is constantly in progress to improve the design and technology - improvements that increase your safety and efﬁciency.
GENERAL SAFETY PRECAUTIONS • 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). • The front hand guard is not designed solely to activate the chain brake.
GENERAL SAFETY PRECAUTIONS of the front hand guard, the chain brake can only be activated by the inertia action. Will my hand always activate the chain brake during a kickback? No. It takes a certain force to move the hand guard forward.
GENERAL SAFETY PRECAUTIONS chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.
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.
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.
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 •...
GENERAL SAFETY PRECAUTIONS The position of the chain tensioning screw on our chain saws varies from model to model. See instructions under the heading What is what? to ﬁnd out where it is on your model. Lubricating cutting equipment WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.
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).
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).
• 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. • In temperatures below 32°F (0°C) some oils become too viscous.
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.
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. Note! Pull the front hand guard towards the front handle. The chain brake is now disengaged.
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.
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.
In order to keep control of your saw, always maintain a ﬁrm foothold. Never work on a ladder, in a tree or on any other insecure support. Always use a fast cutting speed, i.e. full throttle. Take great care when you cut with the top edge of the bar, i.e.
Two factors decide whether the chain will jam or the object that you are cutting will split: the ﬁrst is how the object is supported before and after cutting, and the second is whether it is in tension. In most cases you can avoid these problems by cutting in two stages;...
Start by cutting from above (about 1/3 of the way through). 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...
Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees away from the intended felling direction.
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.
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.
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.
Checking the brake trigger Place the chain saw on ﬁrm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop. Grasp the chain saw ﬁrmly, wrapping your ﬁngers and thumbs around the handles.
Vibration damping system Regularly check the vibration damping units for cracks or deformation. Make sure the vibration damping units are securely attached to the engine unit and handle unit. Stop switch Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
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.
A damaged air ﬁlter must always be replaced. A HUSQVARNA chain saw can be equipped with different types of air ﬁlters according to working conditions, weather, season, etc. Contact your dealer for advice.
Needle bearing lubrication The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). When lubricating, remove the clutch cover by loosening the two bar nuts. Lay the saw on its side with the clutch drum upwards.
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 carburetor. Special measures are therefore often required: • Partly mask the air inlet on the starter to increase the working temperature of the engine.
