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.

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.
WARNING! Running an engine in a confined or badly ventilated area can result in death
!
due to asphyxiation or carbon monoxide poisoning.
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.
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.
WARNING! Never allow children to use or be in the vicinity of the machine. As the

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 servicing dealer.
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.
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.
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.
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 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.
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. These 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.
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.
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.
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.
Never use a machine that has a faulty muffler.

English
Regularly check that the muffler is securely attached to the machine.
1155647-95 Rev. 5 2014-12-01
GENERAL SAFETY PRECAUTIONS
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:
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.
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.
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. 35-50 Nm (3.5­5 kpm).
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.
WARNING! A faulty cutting attachment may increase the risk of accidents.
!
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:
1 If you have spilt fuel on it. Wipe off the spillage and allow
remaining fuel to evaporate.
2 If 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.
3 If 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 gas 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.
In order to prevent unintentional starting of the engine, the spark plug cap must always be removed during long-term storage, if the machine is not under close supervision and when performing all service measures.
WARNING! Take care when handling fuel. Bear in mind the risk of fire, explosion and
!
inhaling fumes.
Fuel
Gasoline
CAUTION! Always use a quality gasoline/oil mixture with an
octane rating of at least 87 octane ((RON+MON)/2). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded gasoline/oil mixture. Leaded gasoline will destroy the catalytic converter.
Use low-emission gasoline, also known as alkylate gasoline, if it is available.
This engine is certified to operate on unleaded gasoline.
The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, 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 two­stroke engine oil, which is specially formulated for our air­cooled 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.
Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.
CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of gasoline and two-stroke engine 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.
