INTR ODUCTION

Dear customer!

Cong ratulations on your choice to buy a Husqv arna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During over 300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the ﬁrst motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working today.

GENERAL SAFETY PRECAUTIONS

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

No. First your brake must be in working order. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activ ate 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 br ake m ust be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the sa w chain. Third, the chain brake may be activated but if the bar is to 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 lock

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

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 b

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.

y vibration damping units.

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).

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.

Stop switch

Use the stop switch to switch off the engine.

GENERAL SAFETY PRECAUTIONS

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum 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 mesh.

CAUTION! The mufﬂer gets very hot during and after use. This also applies during idling. Be aw are 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.

vernment rules

• Maintain the correct depth gauge setting! Follow our

instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of

kickback.

Keep the chain properly tensioned! If the chain is slack

• it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.

•

Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to

break and lead to increased wear on the bar, chain and drive sprocket.

Cutting equipment designed to reduce kickback

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.

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to:

• Reduce the risk of kickback.

• Reduce the risk of the saw chain breaking or jumping off the bar

• Obtain optimal cutting performance.

• Extend the life of cutting equipment.

• Avoid increasing vibration levels.

General rules

• Only use cutting equipment recommended by us! See instructions under the heading Technical data.

•

Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended ﬁle gauge.

A damaged or badly sharpened chain increases

the risk of accidents.

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

eeping the chain sharp and well-maintained you can

and k reduce the effects of kickback.

Bar

The smaller the tip radius the lower the chance of kickback.

Chain

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.

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.

• Check that the chain is correctly tensioned. A slac k chain

will mo correctly.

• Always ﬁle cutting teeth from the inside face. Reduce the pressure on the retur ﬁrst, then turn the chain saw and ﬁle the teeth on the other side.

n stroke. File all the teeth on one side

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 the correct depth gauge setting and bevel for the depth gauge.

• Place the depth gauge tool over the chain. Detailed

ormation regarding the use of the depth gauge tool, will

inf be found on the package f or the depth gauge tool. Use the ﬂat ﬁle to ﬁle off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the ﬁle along the depth gauge tool.

ou use our depth gauge tool to acheive

• 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 w

orn 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 f

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

or your particular chain.

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 ev ery time you refuel. NOTE! A ne w chain has a r the tension more frequently.

Tension the chain as tightly as possible, but not so tight that
