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 Charles 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 water-powered plant. During the
more than 300 years of beeing, 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 rst 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
building and construction industry. Husqvarna
s aim is also to be in the front edge according to ergonomics, usability, security and
environmental protection. That is the reason why we have developed many different features to provide 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 satised 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 will sell this machine, make sure that the buyer will get the operator
s manual.
Good luck on using your Husqvarna machine!

GENERAL SAFETY PRECAUTIONS
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.
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.
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.
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.
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.
12 –
English
GENERAL SAFETY PRECAUTIONS
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 minimize 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.
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
Quick release
There is an easily accessible, quick release tted at the front
as a safety precaution in case the engine catches re, 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 tted to the
support hook.
Check that the harness straps are correctly positioned. Once
the harness and machine have been adjusted, check that the
harness quick release works correctly.
Mufer
The mufer is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
A mufer tted with a catalytic converter is also designed to
reduce harmful exhaust gases.
In countries that have a warm and dry climate there is a
signicant risk of re. We therefore t certain mufers with a
spark arrestor mesh. Check whether the mufer on your
machine is tted with this kind of mesh.
For mufers 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 mufer.
Regularly check that the mufer is securely attached to the
machine.
!
WARNING! Never use a cutting attachment
without an approved guard. See the chapter
on Technical data. If an incorrect or faulty
guard is tted 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 ngers, hands or wrists. The risk
increases at low temperatures.
English
– 13
GENERAL SAFETY PRECAUTIONS
If the mufer on your machine is tted 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 tting, 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.
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.
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.
Cutting equipment
Saw blades are intended for cutting brous types of wood.
Grass blades and grass cutters are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.
!
WARNING! Mufers tted 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
re!
!
WARNING! The inside of the mufer contain
chemicals that may be carcinogenic. Avoid
contact with these elements in the event of a
damaged mufer.
!
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
re. Never start the machine indoors or near
combustible material!
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 le 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.
