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 Personal protective equipment
IMPORTANT!
The machine is only designed for trimming grass.
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.
ARNING! Running an engine in a confined
or badly ventilated area can result in death
!
due to asphyxiation or carbon monoxide
poisoning.
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. Ask
your dealer for help in choosing the right equipment.
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.
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

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.
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.
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.
Stop s witch
Use the stop s witch 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 attac hment guard
This guard is intended to pre vent 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.
Muffl er
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.
Vibration damping system
our 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.
–
Regularly check that the muffler is securely attached to the
machine.
English
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:
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.)
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.
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.
• 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.
• 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.
