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 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 in existence, 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 chainsaws 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 the building and construction industry. Husqvarna
′ s aim is also to be at the front edge for
ergonomics, usability, security and environmental protection. That is the reason why we have developed many different
features to add to 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 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 (usage, service, maintenance, etc), the life span and
the second-hand value of the machine can be extended. If you sell this machine, make sure that the operator
′ s manual
is passed on to the buyer.
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.

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 service workshop.
Thr ottle trigger 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 that the throttle trigger is locked at idle setting
when the throttle trigger lockout is released.
Press the throttle lockout and make sure it returns to its
original position when you release it.
Check that the throttle trigger and throttle lockout move
freely and that the return springs work properly.
IMPORTANT! All servicing and repair work on the
machine requires special training.This is especially true

See instr uctions 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 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.
Vibration damping system
Y our machine is equipped with a vibration damping
system that is designed to minimize 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.
!
W ARNING! 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.

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

Regularly check that the muffler is securely attached to
the machine.
!
W ARNING! Overexposure to vibration
can lead to circulatory damage or nerve
damage in people who have impaired
circulation. Contact your doctor if you

GENERAL SAFETY PRECAUTIONS
10 – English
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.
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 fibrous types of wood.
Grass blades and grass knifes are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.
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.
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.

attachment.This continues to rotate even
after the throttle has been released.
Ensure that the cutting attachment has
stopped completely and disconnect the
spark plug cap before you start to work
on it.
!
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.
