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.

!
W ARNING! This machine produces an
electromagnetic field during operation.
This field may under some
circumstances interfere with active or
passive medical implants. To reduce the
risk of serious or fatal injury, we
recommend persons with medical
implants to consult their physician and
the medical implant manufacturer before
operating this machine.
!
W ARNING! Running an engine in a
confined or badly ventilated area can
result in death due to asphyxiation or
carbon monoxide poisoning.
!
W 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 machine. This can
mean a risk of serious personal injury.
Therefore remove the spark plug cap
when the machine is not under close
supervision.
IMPOR TANT!
A backpack type chain saw is a dangerous tool if used
carelessly or incorrectly and can cause serious, even
fatal injuries. 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.
!
W 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.

GENERAL SAFETY PRECA UTIONS
English – 7
GLO VES
Gloves should be worn when necessary, e.g. when fitting
cutting attachments.
BOOTS
Wear boots with saw protection, steel toe-cap and non-
slip sole.
TROUSERS
Use trousers with saw protection.
CLOTHING
Wear clothes made of a strong fabric and avoid loose
clothing that can catch on twigs and branches. Do not
wear jewellery, shorts sandals or go barefoot. Secure hair
so it is above shoulder level.
FIRST AID KIT
Always have a first aid kit nearby.
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.
IMPOR TANT!
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.

GENERAL SAFETY PRECAUTIONS
8 – English
Check that the throttle trigger 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.
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.
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
The machine’s vibration damping system reduces the
transfer of vibrations.
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
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 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.
!
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
English – 9
Regularly check that the muffler is securely attached to
the machine.
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.
Harness
Check that the harness is not damaged.
In an emergency situation, release yourself from machine
and harness according to the following method.
Cutting equipment
This section describes how you can achieve maximum
clearing capacity and extend the life of the cutting
attachment through correct maintenance and using the
right type of cutting attachment.
•Only use cutting equipment recommended by us!
•Keep the chain’s cutting teeth properly
sharpened! Follow our instructions and use the
recommended file gauge. A damaged or badly
sharpened chain increases the risk of accidents.
•Maintain the correct raker clearance! Follow our
instructions and use the recommended raker
gauge. Too large a clearance increases the risk of
kickback.
•Keep the chain properly tensioned! If the chain is
slack it is more likely to jump off and lead to increased
wear on the bar, chain and drive sprocket.
•Keep cutting equipment well lubricated and
properly maintained! A poorly lubricated chain is
!
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

more likely to break and lead to increased wear on the
bar, chain and drive sprocket.
Specification of bar and saw chain
When the cutting attachment supplied with your machine
has to be replaced, because it is worn out or damaged,
you must only fit the types of bar and saw chain
recommended by us.
Guide bar
• Length (inches/cm)
• Chain pitch (inches). The spacing between the drive
links of the chain must match the spacing of the teeth
on the bar tip sprocket and drive sprocket.
• Number of drive links. The number of drive links is
determined by the length of the bar, the chain pitch
and the number of teeth on the bar tip sprocket.
• Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
• Lubrication hole and hole for the chain tensioner.
Saw chain
• Saw chain pitch (inches). (The distance between
three drive links, divided by two.)
• Drive link width (mm/inches)
!
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.
!
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
spark plug cap before you start to work
on it.
