GENERAL SAFETY PRECA UTIONS

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. Do not hesitate to contact your dealer or us if you hav e an y questions about the use of the chain saw. We will willingly be of service and provide you with advice as well as help you to use your chain saw both efﬁciently and safely. Attend a training course in chain saw usage if possible. 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. Visit your dealer regularly to see whether you can beneﬁt from new features that have been introduced.

ersonal protective equipment

WARNING! Most chain saw accidents happen when the chain touches the

operator. You must use approved personal protective equipment whenever you use the machine. Per sonal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.

• Boots with saw protection, steel toe-cap and non-slip sole

• Always have a ﬁrst aid kit nearby.

• Fire Extinguisher and Shovel

Generally clothes should be close-ﬁtting without

icting your freedom of movement.

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. If your hand only lightly touches the front guard or slips over it, the force ma y not be enough to trigger the chain brake. You should also maintain a ﬁrm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you.

There are also certain positions in which your hand cannot reach the front hand guard to activ brake; for example, when the saw chain is held in felling position.

Will my inertia activated chain brake always activate during kickback in the event of a kickback?

No. First y our brak e m ust be in w orking order . T esting the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do bef ore you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance.

Will my chain brake always protect me from injury in the event of a kickback?

No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake ma y be activated b ut if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you.

Only you and proper working technique can eliminate kickback and its danger.

Throttle lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you g rasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting.

Chain catcher

The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).

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.

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 transfer of vibration between the engine unit/cutting equipment and the machine chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.

Cutting hardwoods (most broadleaf trees) creates more vibr with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.

Stop switch

Use the stop switch to switch off the engine.

WARNING! Overexposure to vibration can lead to circulatory damage or nerve

damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. These symptoms may be increased in cold temperatures.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minim um and to direct exhaust fumes away from the user.

WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

In areas with a hot, dry climate there is a high risk of ﬁres. These areas are sometimes subject to go requiring among other things the mufﬂer must be equipped with an approved type of spark arrestor screen.

CAUTION! The mufﬂer gets very hot during and after use. This also applies during idling. Be aware of the ﬁre hazard, especially when working near ﬂammable substances and/or vapours.

WARNING! Never use a saw without a mufﬂer, or with a damaged mufﬂer. A damaged mufﬂer may substantially increase the noise level and the ﬁre hazard. Keep ﬁre ﬁghting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.

A chain is made up of a number of links, which are available in standard and low-kickback versions.

IMPORTANT! No saw chain design eliminates the danger of kickback.

WARNING! Any contact with a rotating saw chain can cause extremely serious injuries.

Some terms that describe the bar and chain

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.

Bar

• Length (inches/cm)

• Number of teeth on bar tip sprocket (T).

• Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.

WARNING! Faulty cutting equipment or the wrong combination of bar and saw

chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the ﬁling instructions. See instructions under the heading Technical data.

The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything.

By using cutting equipment with ”built-in” kickback reduction and keeping the chain sharp and wellmaintained you can reduce the effects of kickback.

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. If the chain is very blunt it will produce wood powder and no chips or shavings.

See instructions under the heading Technical data for

ormation about sharpening your chain.

WARNING! Departure from the sharpening instructions considerably increases the risk of kickback.

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.

When you sharpen a cutting tooth there are four important

actors to remember.

English – 13

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

• 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. See instructions under the heading Technical data to ﬁnd the correct depth gauge setting for your particular chain.

WARNING! The risk of kickback is increased if the depth gauge setting is

too large!

Adjustment of depth gauge setting

• The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.

• You will need a ﬂat ﬁle and a depth gauge tool. We recommend that y acheive the correct depth gauge setting and bevel f or the depth gauge.

Tensioning the chain

WARNING! A slack chain may jump off the bar 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.

Check the chain tension every time you refuel. NOTE! A

w chain has a running-in period during which you

ne should check the tension more frequently.
