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.

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.
A
B
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 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
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.
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.
ARNING! Never use a cutting attachment

GENERAL SAFETY PRECA UTIONS
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to reduce 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.
Quick release
There is an easily accessible, quick release fitted at the front
as a safety precaution in case the engine catches 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 clearing saw.
Check that the harness straps are correctly positioned. Once
the harness and machine have been adjusted, check that the
harness quick release works correctly.
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.
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.
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.
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.
–
English
GENERAL SAFETY PRECAUTIONS
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! 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!
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.
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: 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
fire. Never start the machine indoors or near
combustible material!
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.
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.
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.

GENERAL SAFETY PRECAUTIONS
Cutting equipment
Saw blades are intended for cutting fibrous types of wood.
Grass blades and grass cutters 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.
Sharpening grass cutters and grass blades
• See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and cutters
using a single-cut flat file.
• Sharpen all edges equally to maintain the balance of the
blade.
WARNING! Always discard a blade that is
bent, twisted, cracked, broken or damaged
!
in any other way. Never attempt to straighten
a twisted blade so that it can be reused. Only
use original blades of the specified type.
Sharpening the saw blade
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.
Keep the correct setting on the saw blade! Follow our
instructions and use the recommended setting tool. An
incorrectly set saw blade increases the risk of jamming and
kickback, and damage to the saw blade.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
• See the cutting attachment packaging for correct
sharpening instructions.
A correctly sharpened blade is essential for working efficiently
and to avoid unnecessary wear to the blade and clearing saw.
• Make sure that the blade is well supported when you file
it. Use a 5.5 mm round file with a file holder.
• The filing angle is 15°. File alternate teeth to the right and
those in between to the left. If the blade has been heavily
pitted by stones it may be necessary to dress the top
edges of the teeth with a flat file, in exceptional cases. If
so, this should be done before filing with a round file. The
top edges must be filed down by the same amount for all
the teeth.
10 – English
GENERAL SAFETY PRECAUTIONS
Adjust the blade setting. This should be 1 mm.
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.
• 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.

ASSEMBLY
Assembling the handlebar and throttle
• Remove the screw at the rear of the throttle handle.
• Slide the throttle handle onto the right side of the
handlebar, (see diagram).
• Align the screw hole in the throttle handle with the hole in
the handlebar.
•Refit the screw in the hole in the rear of the throttle handle.
• Screw the screw through the handle and handlebar.
