INTRODUCTION

Dear Customer,

Congratulations 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 Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During the more than 300 years in existence, 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. The business concept is to develop, manufacture and market motor-driven products for forestry and gardening, as well as for the building and construction industry. Husqvarna′s aim is also to be at the front edge for ergonomics, usability, security and environmental protection. That is the reason why we have developed many different features to add to our products within these areas.

We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very long time to come. The purchase of one of our products 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 authorised dealers, ask for the address of your nearest service workshop.

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 (usage, service, maintenance, etc), the life span and the second-hand value of the machine can be extended. If you sell this machine, make sure that the operator′s manual is passed on to the buyer.

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 PRECAUTIONS

GLOVES

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

BOOTS

Wear sturdy, non-slip boots.

CLOTHING

Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level.

FIRST AID KIT

Always have a first aid kit nearby.

Machine′s safety equipment

This section describes the machine′s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the ”What is what?” section to locate where this equipment is positioned on your machine.

The life 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 service workshop.

IMPORTANT! All servicing and repair work on the machine requires special training.This is especially true of the machine′s 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.

	!	WARNING! 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.

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

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

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

Check that the throttle trigger and throttle lockout move freely and that the return springs work properly.

See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a

GENERAL SAFETY PRECAUTIONS

standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked. See instructions under the heading Maintenance.

Stop switch

Use the stop switch to switch off the engine.

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

Cutting attachment guard

This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment.

Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked.

Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.

WARNING! Never use a cutting

! attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is fitted this can cause serious personal injury.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.

Using incorrectly wound cord or a blunt or incorrect cutting attachment (wrong type or incorrectly filed, see instructions under the heading Filing the blade) increases the level of vibration.

The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit.

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.

Muffler

The muffler 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.

8 – English

GENERAL SAFETY PRECAUTIONS

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!
	!	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!

Locking nut

A locking nut is used to secure some types of cutting attachment.

When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.) Tighten the nut using the socket spanner.

The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.

Harness

Check that the harness is not damaged.

In an emergency situation, release yourself from machine and harness according to the following method.

Cutting equipment

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

•Reduce the risk of blade thrust.

•Obtain maximum cutting performance.

•Extend the life of cutting equipment.

IMPORTANT!

Only use cutting attachments with the guards we recommend! See the chapter on Technical data.

Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter.

Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.

English – 9

GENERAL SAFETY PRECAUTIONS

WARNING! Always stop the engine before

!doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.

WARNING! Using an incorrect cutting

!attachment or an incorrectly sharpened blade increases the risk of blade thrust.

Cutting equipment

Grass blades and grass knifes are intended for cutting coarse grass.

A trimmer head is intended for trimming grass.

General rules

Only use cutting attachments with the guards we recommend! See the chapter on Technical data.

Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.

Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.

Sharpening grass knifes and grass blades

•See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and knifes using a single-cut flat file.

•Sharpen all edges equally to maintain the balance of the blade.

	!	WARNING! Always discard a blade that is
		bent, twisted, cracked, broken or
		damaged in any other way. Never attempt
		to straighten a twisted blade so that it
		can be reused. Only use original blades
		of the specified type.

Trimmer head

IMPORTANT!

Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.

•Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.

•Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared.

•The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

•Make sure that the cutter on the trimmer guard is intact.This is used to cut the cord to the correct length.

•To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.

FUEL HANDLING

Fuel safety

Never start the machine:

1If you have spilt fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.

2If you have spilt fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

Transport and storage

•Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.

•When storing and transporting fuel always use approved containers intended for this purpose.

•When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to find out where to dispose of excess fuel.

•Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

•The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage.

•Secure the machine during transport.

	!	WARNING! Take care when handling fuel.
		Bear in mind the risk of fire, explosion
		and inhaling fumes.

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

!	WARNING! Fuel and fuel fumes are
	highly inflammable and can cause
	serious injury when inhaled or allowed to
	come in contact with the skin. For this
	reason observe caution when handling
	fuel and make sure there is adequate
	ventilation.

Petrol

CAUTION! Always use a quality petrol/oil mixture at least 90 octane (RON). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter.

Use low-emission petrol, also known as alkylate petrol, if it is available.

•The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 socalled knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage.

•When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

•For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines.

•Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

•Never use oil intended for four-stroke engines.

•A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters.

•Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil.

1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.

Petrol, litre	Two-stroke oil, litre
	2% (1:50)	3% (1:33)
5	0,10	0,15
10	0,20	0,30
15	0,30	0,45
20	0,40	0,60

English – 15

FUEL HANDLING

Mixing

•Always mix the petrol and oil in a clean container intended for fuel.

•Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.

•Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.

•Do not mix more than one month’s supply of fuel at a time.

•If the machine is not used for some time the fuel tank should be emptied and cleaned.

	!	WARNING! The catalytic converter
		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.

Fueling

	!	WARNING! Taking the following
		precautions, will lessen the risk of fire:

Do not smoke or place hot objects near fuel.

Always shut off the engine before refuelling.

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.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area and source before starting.

•Always use a fuel container with an anti-spill valve.

•Clean the area around the fuel cap. Contamination in the tank can cause operating problems.

•Ensure that the fuel is well mixed by shaking the container before filling the tank.

16 – English

STARTING AND STOPPING

Check before starting

•Never use the machine without a guard nor with a defective guard.

•All covers must be correctly fitted and undamaged before you start the machine.

•Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.

•Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked.

•Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm.The tightening torque of the locking nut should be 35-50 Nm.

•Check that the blade guard is not damaged or cracked. Replace the blade guard if it is exposed to impact or is cracked.

•Check that the trimmer head and trimmer guard are not damaged or cracked. Replace the trimmer head or

trimmer guard if they have been exposed to impact or are cracked.

Starting and stopping

	!	WARNING! The complete clutch cover
		and shaft must be fitted before the
		machine is started, otherwise the clutch
		can come loose and cause personal
		injury.

Always move the machine away from the refuelling area and source before starting. Place the machine on a flat surface. Ensure the cutting attachment cannot come into contact with any object.

Make sure no unauthorised persons are in the working area. Otherwise there is a risk of serious personal injury.The safety distance is 15 metres.

Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord. Never twist the starter cord around your hand.

Repeat pulling the cord until the engine starts. When the engine starts. return choke control to run position and apply full throttle; the throttle will automatically disengage from the start setting.

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.

CAUTION! Do not put any part of your body in marked area. Contact can result in burns to the skin, or electrical shock if the spark plug cap has been damaged. Always use gloves. Do not use a machine with damaged spark plug cap.

WORKING TECHNIQUES

General working instructions

IMPORTANT!

This section describes the basic safety precautions for working with brush cutters and trimmers.

If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.

Avoid all usage which you consider to be beyond your capability.

You must understand the difference between forestry clearing, grass clearing and grass trimming before use.

Basic safety rules

1 Look around you:

•To ensure that people, animals or other things cannot affect your control of the machine.

•To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.

•CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

2Inspect the working area. Remove all loose objects, such as stones, broken glass, nails, steel wire, string, etc. that could be thrown out or become wrapped around the cutting attachment.

3Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc.Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.

4Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly.Take great care when working on sloping ground.

5Always carry this backpack type blower in its shoulder harness while operating.

6Keep a good balance and a firm foothold.

7Always hold the machine with both hands.

8Keep the cutting attachment below waist level.

9Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance.

10Never put the machine down with the engine running unless you have it in clear sight.

	!	WARNING! Neither the operator of the
		machine nor anyone else may attempt to
		remove the cut material while the engine
		is running or the cutting equipment is
		rotating, as this can result in serious
		injury.

Stop the engine and cutting equipment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burnt if you touch it.

	!	WARNING! Watch out for thrown objects.
		Always wear approved eye protection.
		Never lean over the cutting attachment
		guard. Stones, rubbish, etc. can be thrown
		up into the eyes causing blindness or
		serious injury.

Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 metres. Stop the machine immediately if anyone approaches. Never swing the machine around without first checking behind you to make sure no-one is within the safety zone.

Basic working techniques

Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.

	!	WARNING! Sometimes branches or
		grass get caught between the guard and
		cutting attachment. Always stop the
		engine before cleaning.
	!	WARNING! Machines fitted with saw
		blades or grass blades can be thrown
		violently to the side when the blade comes
		into contact with a fixed object. This is
		called blade thrust. A blade thrust can be
		violent enough to cause the machine and/
		or operator to be propelled in any
		direction, and possibly lose control of the
		machine. Blade thrust can occur without
		warning if the machine snags, stalls or
		binds. Blade thrust is more likely to occur
		in areas where it is difficult to see the
		material being cut.

Avoid cutting with the area of the blade between the 12 o'clock and 3 o'clock positions. Because of the speed of rotation of the blade, blade thrust can occur if you attempt to cut thick stems with this area of the blade.

WORKING TECHNIQUES

Grass clearing using a grass blade

•Grass blades and grass knifes must not be used on woody stems.

•A grass blade is used for all types of tall or coarse grass.

•The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to- right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.

•If the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.

•Try to work rhythmically. Stand firmly with your feet apart. Move forward after the return stroke and stand firmly again.

•Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.

•Reduce the risk of material wrapping around the blade by following these instructions:

1Always work at full throttle.

2Avoid the previously cut material during the return stroke.

•Stop the engine, unclip the harness and place the machine on the ground before you start to collect the cut material.

Grass trimming with a trimmer head

Trimming

•Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.

•The cord can easily remove grass and weeds up against walls, fences, trees and borders. However it can also damage sensitive bark on trees and bushes, and damage fence posts.

•Reduce the risk of damaging plants by shortening the cord to 10-12 cm and reducing the engine speed.

Clearing

•The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord.

•The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.

•When trimming and clearing, you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head.

Cutting

•The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.

•Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

Sweeping

•The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro.

•When cutting and sweeping you should use full throttle to obtain the best results.

MAINTENANCE

Carburettor

Adjusting the idle speed (T)

Check that the air filter is clean. When the idle speed is correct, the cutting attachment should not rotate. If adjustment is required, close (turn clockwise) the idle adjustment screw T, with the engine running, until the cutting attachment starts to rotate. Open (turn anticlockwise) the screw until the cutting attachment stops. The idle speed is correctly set when the engine runs smoothly in all positions, and there is a clear margin to the speed at which the cutting attachment starts to rotate.

	!	WARNING! If the idle speed cannot be
		adjusted so that the cutting attachment
		stops, contact your dealer/service
		workshop. Do not use the machine until
		it has been correctly adjusted or
		repaired.

Air filter

The air filter must be regularly cleaned to remove dust and dirt in order to avoid:

•Carburettor malfunctions

•Starting problems

•Loss of engine power

•Unnecessary wear to engine parts.

•Excessive fuel consumption.

Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air filter

Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Ensure that the filter is dry before refitting it.

An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced.

Fuel filter

1

1 Fuel filter

When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.

Bevel gear

The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. Use HUSQVARNA special grease.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

Spark plug

The spark plug condition is influenced by:

•Incorrect carburettor adjustment.

•An incorrect fuel mixture (too much or incorrect type of oil).

•A dirty air filter.

English – 21

MAINTENANCE

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.

If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,6-0,7 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is fitted with a suppressor.

Drive shaft

The flexible drive axle is lubricated with Husqvarna drive axle grease. The axle must be lubricated at least every 6 months.

•Lift up the locking button that holds the drive shaft sleeve in the clutch cover.

•Pull the drive shaft sleeve out of the clutch cover.

•Remove the drive shaft from the sleeve either by shaking it out or pulling it out using pliers.

•Apply the grease from the tube along the whole axle. Spread with a brush or cloth.

•Slide the drive shaft back into the sleeve. Make sure the shaft engages correctly by turning it and pushing at the same time.

•When the shaft is correctly installed in the sleeve, the end of the shaft should project about 10 mm beyond the edge of the sleeve.

•Install the drive shaft sleeve in the clutch cover so that the hole is positioned directly underneath the locking button on the clutch cover.

• Make sure the shaft engages correctly by turning it and pushing at the same time.

INTRODUCTION

Cher client,

Félicitations pour ce choix d’un produit Husqvarna. Husqvarna a vu le jour en 1689 lorsque le roi Karl XI décida de construire un arsenal pour la fabrication des mousquets au bord de la rivière Huskvarna. Le choix de l’emplacement était logique puisque la rivière Huskvarna servait à produire de l’énergie hydraulique et constituait donc une sorte de centrale hydraulique. En plus de 300 ans d’existence, l’usine Husqvarna a fabriqué de nombreux produits, depuis les cuisinières à bois jusqu’aux équipements de cuisine modernes, sans oublier les machines à coudre, les bicyclettes, les motos, etc. La première tondeuse à moteur a été lancée en 1956, suivie en 1959 de la première tronçonneuse. C’est dans ce secteur que Husqvarna est actif aujourd’hui.

Husqvarna est aujourd’hui un des plus grands fabricants du monde de produits destinés à l’entretien des forêts et des jardins. La qualité et les performances sont nos priorités. Notre concept d’affaires est de développer, fabriquer et commercialiser des produits à moteur pour l’entretien des forêts et des jardins et pour les entreprises de construction et d’aménagement des sols. L’objectif d’Husqvarna est aussi d’être à la pointe du progrès en matière d’ergonomie, de facilité d’utilisation, de sécurité et de protection de l’environnement; un grand nombre d’innovations ont été développées pour améliorer les produits dans ces domaines.

Nous sommes persuadés que vous apprécierez la qualité et les performances de nos produits pendant de longues années. L’achat d’un de nos produits vous garantit une assistance professionnelle au niveau du service et des réparations en cas de besoin. Si la machine n’a pas été achetée chez un de nos revendeurs autorisés, demandez à un revendeur l’adresse de l’atelier d’entretien le plus proche.

Nous espérons que cette machine vous donnera toute satisfaction et qu’elle vous accompagnera pendant de longues années. N’oubliez pas que ce manuel d’utilisation est important. En suivant les instructions qu’il contient (utilisation, révision, entretien, etc.), il est possible d’allonger considérablement la durée de vie de la machine et d’augmenter sa valeur sur le marché de l’occasion. En cas de vente de la machine, ne pas oublier de remettre le manuel d’utilisation au nouveau propriétaire.

Nous vous remercions d'utiliser un produit Husqvarna !

Husqvarna AB travaille continuellement au développement de ses produits et se réserve le droit d’en modifier, entre autres, la conception et l’aspect sans préavis.
