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 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 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.
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 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 will sell this machine, make sure that the buyer will get the operator
′
s manual.
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.

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 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.
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 hedge
trimmer and apply full throttle. Release the throttle trigger and
check that the blades stop and remain stationary. If the blades
move when the throttle trigger is in the idle position then the
carburettor idle setting must be adjusted. 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.
Hand guar
d
The hand guard pre
vents hands from coming into contact with
the moving blades, for example, if the operator loses grip on
the front handle.
Check that the hand guard is fitted correctly.
Check that the hand guard is undamaged.
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.

GENERAL SAFETY PRECA
UTIONS
Vibration damping system
Y
our 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 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.
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.
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.
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! 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.
!
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
Blades
To ensure good cutting results it is important that the contact
pressure between the blades is correct. The contact pressure
is adjusted by turning the screws on the underside of the bar
clockwise as far as they will go. Then turn the screws
anticlockwise a 1/4 turn. Lock the screws using the locking nut
on the top of the bar. Check that the screws are loose enough
to allow the washers under the screw heads to slide sideways.
When the blades are correctly adjusted the play between the
blades should be 0,2–0,4 mm, measured at the screws.
The edges of the blades are too hard to be filed. Dull blades
should be sharpened using a grinder.
Replace the blades if they are bent or damaged.
Blade guard
The blade guard (A) is intended to protect against any part of
the body coming into contact with the blades (B).
Check that the blade guard is not damaged or distorted.
Replace the blade guard if it is bent or damaged.
Gear housing
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear housing.
