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.

IMPOR TANT!
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.

BOO TS
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

Mac hine ′ s safety equipment
This section descr ibes 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.
Thr ottle lockout
The throttle loc kout 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 control 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 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.
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.
!
W 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.

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.
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to reduce 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! 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.
!
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.

GENERAL SAFETY PRECAUTIONS

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 screen. Check whether the muffler on your
machine is fitted with this kind of screen.
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.
Regularly check that the muffler is securely attached to the
machine.
If the muffler on your machine is fitted with a spark arrestor
screen this must be cleaned regularly. A blocked screen 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!

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.
Trimmer head
•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.
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.
!
WARNING! A faulty cutting attachment may
increase the risk of accidents.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly
around the drum, otherwise the machine will generate
harmful vibration.
