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 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 PRECAUTIONS

Important

IMPORTANT!

The machine is only designed for trimming grass, grass clearing and/or forestry clearing.

The only accessories you can operate with this engine unit are the cutting attachments we recommend in the chapter on Technical data.

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 a machine that has been modiﬁed in any way from its original speciﬁcation.

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.

The machine operator must ensure that no people or animals come closer than 15 metres while working. When several operators are working in the same area the safety distance should be at least twice the tree height and no less than 15 metres.

HELMET

A helmet should be worn if the trees being cleared are taller than 2 m.

HEARING PROTECTION

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.

Personal protective equipment

IMPORTANT!

A clearing saw, brushcutter or trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual.

You must use approved personal protective equipment whenever you use the machine. Personal 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.

WARNING! Listen out for warning signals or shouts when you are wearing hearing

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

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.

GENERAL SAFETY PRECAUTIONS

Machine ′′

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 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.

′′

s safety equipment

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.

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

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 machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a 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.

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 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 lock is released.

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.

GENERAL SAFETY PRECAUTIONS

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.

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.

Quick release

There is an easily accessible, quick release ﬁtted at the front as a safety precaution in case the engine catches ﬁre, or in any other situation that requires you to free yourself from the machine and harness. See instructions under the heading Adjusting the harness and clearing saw.

Certain harnesses also have a quick release ﬁtted to the support hook.

Vibration damping system

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

Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment.

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

Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.

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.

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.

12 –

English

GENERAL SAFETY PRECAUTIONS

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment.

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.

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.)

When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut.

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:

Engine exhaust fumes contain carbon

monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated.

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!

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.

Locking screw

The lock screw must be tightened securely for ball-bearingmounted support cups.

GENERAL SAFETY PRECAUTIONS

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.

Maintain the correct blade setting! Follow our instructions and use the recommended ﬁle gauge.

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 kickback.

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.

Keep the correct setting on the saw blade! Follow our instructions and use the recommended setting tool. An incorrectly set saw blade increases the risk of jamming and kickback, and damage to the saw blade.

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

Cutting equipment

Saw blades are intended for cutting ﬁbrous types of wood.

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

A trimmer head is intended for trimming grass.

14 –

English

GENERAL SAFETY PRECAUTIONS

Sharpening grass cutters and grass blades

• See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters 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.

Sharpening the saw blade

Adjust the blade setting. This should be 1 mm.

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.

• See the cutting attachment packaging for correct sharpening instructions.

A correctly sharpened blade is essential for working efﬁciently and to avoid unnecessary wear to the blade and clearing saw.

• Make sure that the blade is well supported when you ﬁle it. Use a 5.5 mm round ﬁle with a ﬁle holder.

• The ﬁling angle is 15 ° . File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a ﬂat ﬁle, in exceptional cases. If so, this should be done before ﬁling with a round ﬁle. The top edges must be ﬁled down by the same amount for all the teeth.

• 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.
