INTR ODUCTION

Dear customer!

Cong ratulations on your choice to buy a Husqvarna 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.

Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and construction industry.

Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.

It is our wish that you will be satisﬁed with your product and that it will be your companion for a long time. Think of this operator ′ s manual as a valuable document. By following its ′ content (using, service, maintenance etc) the life span and the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the operator ′ s manual, so they will also know how to properly maintain and use it.

Thank you for using a Husqvarna product.

Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.

GENERAL SAFETY PRECA UTIONS

Impor tant

IMPORTANT!

The machine is only designed for cutting branches and twigs.

Never use a machine that has been modiﬁed in any way from its original speciﬁcation.

Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination.

Wear personal protective equipment. See instructions under the heading Personal protective equipment.

Never use the machine in extreme weather conditions such as severe cold, very hot and/or humid climates.

Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualiﬁed specialists. See instructions under the heading Maintenance.

All covers and guards must be ﬁtted before starting. Ensure that the spark plug cap and ignition lead are undamaged to avoid the risk of electric shock.

ARNING! Running an engine in a conﬁned

or badly ventilated area can result in death

due to asphyxiation or carbon monoxide poisoning.

ARNING! Listen out for warning signals or

shouts when you are wearing hearing

protection. Always remove your hearing protection as soon as the engine stops.

HEARING PR OTECTION

Wear hearing protection that provides adequate noise reduction.

EYE PROTECTION

Always wear approved eye protection. If you use a visor then you must also wear approved protective goggles. Approved protective goggles must comply with standard ANSI Z87.1 in the USA or EN 166 in EU countries.

GLOVES

Gloves should be worn when necessary, e.g., when ﬁtting cutting attachments.

ARNING! Never allow children to use or be

in the vicinity of the machine. As the

machine is equipped with a spring-loaded stop switch and can be started by low speed and force on the starter handle, even small children under some circumstances can produce the force necessary to start the machine. This can mean a risk of serious personal injury. Therefore remove the spark plug cap when the machine is not under close supervision.

ARNING! Faulty blades can increase the

risk of accidents.

Personal protective equipment

IMPOR TANT!

GENERAL SAFETY PRECA UTIONS

′

The lif e span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest servicing dealer.

IMPORTANT!

All servicing and repair work on the machine requires special training. This is especially true of the machine safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your nearest service agent.

ARNING! Never use a machine with faulty

safety equipment. The machine’s safety

equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

Thr ottle lock

The throttle loc k 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 movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting.

Check that the throttle control and throttle lock move freely and that the return springs work properly.

See instructions under the heading Start. Start the hedge trimmer and apply full throttle. Release the throttle trigger and check that the blades stop and remain stationary. If the blades move when the throttle trigger is in the idle position then the carburettor idle setting must be adjusted. See instructions under the heading Maintenance.

Stop s witch

Use the stop s witch to switch off the engine.

Make sure the throttle control is locked at the idle setting when the throttle lock is released.

Press the throttle lock and make sure it returns to its original position when you release it.

Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Hand guar d

The hand guard pre vents hands from coming into contact with the moving blades, for example, if the operator loses grip on the front handle.

Check that the hand guard is ﬁtted correctly.

Check that the hand guard is undamaged.

GENERAL SAFETY PRECA UTIONS

Vibration damping system

our 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 engine body, including the blades, is suspended from the handle unit by ﬁve springs.

Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.

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. The risk increases at low temperatures.

Mufﬂ er

Never use a machine that has a faulty mufﬂer.

Regularly check that the mufﬂer is securely attached to the machine.

If the mufﬂer on your machine is ﬁtted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.

WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and

remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁre!

The m ufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

A mufﬂer ﬁtted with a catalytic converter is also designed to reduce harmful exhaust gases.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. We therefore ﬁt certain mufﬂers with a spark arrestor mesh. Check whether the mufﬂer on your machine is ﬁtted with this kind of mesh.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine.

WARNING! The inside of the mufﬂer contain chemicals that may be carcinogenic. Avoid

contact with these elements in the event of a damaged mufﬂer.

WARNING! Bear in mind that:

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!
