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 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.

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.
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 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
!
WARNING! 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.
!
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
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.
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.
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.
Locking nut
A locking nut is used to secure some types of cutting
attachment.
!
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
10 – English
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.
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 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.
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.
!
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 blade thrust.

GENERAL SAFETY PRECAUTIONS
English – 11
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 blade thrust, and damage to the saw blade.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
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.
Sharpening the saw blade
• 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
brush cutter.
• 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.
Adjust the blade setting. This should be 1 mm.
!
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.

GENERAL SAFETY PRECAUTIONS
12 – English
Trimmer head
• 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.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.

FUEL HANDLING
English – 17
Fuel handling
Never start the machine:
1 If you have spilt fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 If you have spilt fuel on yourself or your clothes,
change your clothes. Wash any part of your body that
has come in contact with fuel. Use soap and water.
3 If the machine is leaking fuel. Check regularly for
leaks from the fuel cap and fuel lines.
Transport and storage
•Store and transport the machine and fuel so that there
is no risk of any leakage or fumes coming into contact
with sparks or naked flames, for example, from
electrical machinery, electric motors, electrical relays/
switches or boilers.
• When storing and transporting fuel always use
approved containers intended for this purpose.
• When storing the machine for long periods the fuel
tank must be emptied. Contact your local petrol
station to find out where to dispose of excess fuel.
• The transport guard must always be fitted to the
cutting attachment when the machine is being
transported or in storage.
• Secure the machine during transport.
• Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
Fuel
CAUTION! The machine is equipped with a four-stroke
engine. Make sure that there is always sufficient oil in the
oil tank.
Petrol
Always use an unleaded quality petrol of at least 90
octane (RON).
Use low-emission petrol, also known as alkylate petrol, if
it is available.
• The lowest recommended octane grade is 90 (RON).
If you run the engine on a lower octane grade than 90
so-called knocking can occur. This gives rise to a high
engine temperature and increased bearing load,
which can result in serious engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Engine oil
Check the oil level before starting the machine. A too low
oil level can cause serious damage to the engine.
When the machine is new the engine oil should be
changed after the first month or after 10 hours of
operation.
• For the best result and function use HUSQVARNA
engine oil.
• When HUSQVARNA engine oil is not available

Check before starting
•Check the blade to ensure that no cracks have formed
at the bottom of the teeth or by the centre hole. The
most common reason why cracks are formed is that
sharp corners have been formed at the bottom of the
teeth while sharpening or that the blade has been
used with dull teeth. Discard a blade if cracks are
found.
• Check that the support flange is not cracked due to
fatigue or due to being tightened too much. Discard
the support flange if it is cracked.
• Ensure the locking nut has not lost its captive force.
The nut lock should have a locking force of at least 1.5
Nm.The tightening torque of the locking nut should be
35-50 Nm.
• Check that the blade guard is not damaged or
cracked. Replace the blade guard if it is exposed to
impact or is cracked.
• Check that the trimmer head and trimmer guard are
not damaged or cracked. Replace the trimmer head or
trimmer guard if they have been exposed to impact or
are cracked.
• Never use the machine without a guard nor with a
defective guard.
• All covers must be correctly fitted and undamaged
before you start the machine.
