INTR ODUCTION
1157180-49 Re v . 1 2014-11-24
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.

1157180-49 Re v . 1 2014-11-24
Check that the hand guard is fitted correctly.
Check that the hand guard is undamaged.
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to reduce 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.
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 screen. Check whether the muffler on
your machine is fitted with this kind of screen.
If the muffler on your machine is fitted with a spark
arrestor screen this must be cleaned regularly. A blocked
screen will cause the engine to overheat and may lead to
serious damage.
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.
Gear
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear
housing.
!
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 and exhaust pipes get very
hot during use and remain so for some
time after stopping.This also applies
when idling. 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!

FUEL HANDLING
English – 9
1157180-49 Rev. 1 2014-11-24
Fuel safety
Never start the machine:
1 If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 If you have spilled 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 open 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 gas station
to find out where to dispose of excess fuel. Drain off
the fuel in an approved container outdoors and well
clear of naked flames.
• Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
• 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.
• In order to prevent unintentional starting of the engine,
the spark plug cap must always be removed during
long-term storage, if the machine is not under close
supervision and when performing all service
measures.
Fuel
CAUTION! The machine is equipped with a two-stroke
engine and must always be run using a mixture of
gasoline and two-stroke engine oil. It is important to
accurately measure the amount of oil to be mixed to
ensure that the correct mixture is obtained. When mixing
small amounts of fuel, even small inaccuracies can
drastically affect the ratio of the mixture.
Gasoline
CAUTION! Always use a quality gasoline/oil mixture with
an octane rating of at least 87 octane ((RON+MON)/2). If
your machine is equipped with a catalytic converter (see
chapter on Technical data) always use a good quality
unleaded gasoline/oil mixture. Leaded gasoline will
destroy the catalytic converter.
Use low-emission gasoline, also known as alkylate
gasoline, if it is available.
This engine is certified to operate on unleaded
gasoline.
• The lowest recommended octane grade is 87
((RON+MON)/2). If you run the engine on a lower
octane grade than 87 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.
Two-stroke oil
• For best results and performance use HUSQVARNA
two-stroke engine oil, which is specially formulated for
our air-cooled two stroke-engines.
• Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
• Never use oil intended for four-stroke engines.
• Mixing ratio
50:1 (2%) with HUSQVARNA two-stroke oil.
!
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
!
WARNING! Fuel and fuel fumes are
highly inflammable and can cause
serious injury when inhaled or allowed to
come in contact with the skin. For this
reason observe caution when handling
fuel and make sure there is adequate
ventilation.

Mixing
• Always mix the gasoline and oil in a clean container
intended for fuel.
• Always start by filling half the amount of the gasoline
to be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture.Add the remaining amount of
gasoline.
• Mix (shake) the fuel mixture thoroughly before filling
the machine’s fuel tank.
• Do not mix more than one month’s supply of fuel at a
time.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Fueling
•Clean the area around the fuel cap. Contamination in
the tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the
container before filling the tank.
!
WARNING! The catalytic converter
muffler gets very hot during and after
use. This also applies during idling. Be
aware of the fire hazard, especially when
working near flammable substances and/
or vapors.
!
WARNING! Taking the following
precautions, will lessen the risk of fire:
Refuel in a well ventilated area. Never
fuel the machine indoors.
Do not smoke or place hot objects near
fuel.
Always shut off the engine before

Carburetor
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
Function
• The carburetor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the
carburetor. The air/fuel mixture is adjustable. Correct
adjustment is essential to get the best performance
from the machine.
• The setting of the carburetor means that the engine is
adapted to local conditions, for example, the climate,
altitude, fuel and the type of 2-stroke oil.
Adjusting the idle speed
The T-screw regulates the throttle setting at idle speed. If
the T-screw is turned clockwise this gives a higher idle
speed; turning it anti-clockwise gives a lower idle speed.
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
Adjust the idle speed with the idle adjustment screw T, if
adjustment is necessary. First turn the idle adjustment
screw T clockwise until the blades start to move. Then
turn the idle adjustment screw T anticlockwise until the
blades stop.The idle speed is correctly adjusted when the
engine runs smoothly in every position.There should also
be a clear margin to the speed at which the blades start
to move. The blades must also remain stationary when
the choke control is in the start throttle position.
Rec. idle speed: See the Technical data section.
Muffler
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether
your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
Some mufflers are equipped with a special spark arrestor
screen. If your machine has this type of muffler, you
should clean the screen at least once a week.This is best
done with a wire brush.
On mufflers without a catalytic converter the screen
should be cleaned weekly, or replaced if necessary. On
mufflers fitted with a catalytic converter the screen should
be checked, and if necessary cleaned, monthly. If the
screen is damaged it should be replaced. If the screen
is frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired.
Contact your dealer to inspect the muffler. A blocked
screen will cause the machine to overheat and result in
damage to the cylinder and piston.
CAUTION! Never use a machine with a defective muffler.
!
WARNING! The complete clutch cover
and gear housing must be fitted before
the machine is started, otherwise the
clutch may come loose and cause
personal injury.
!
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
!
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!

Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Fins on the flywheel.
2 Cooling fins on the cylinder.
3 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Spark plug
The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0,9-1,0 mm.
The spark plug should be replaced after about a month in
operation or earlier if necessary.
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
• Carburettor malfunctions.
• Starting problems.
• Loss of engine power.
• Unnecessary wear to engine parts
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.
Fuel filter
When the engine runs short of fuel supply, check the fuel
cap and the fuel filter for blockage.

Gear
There is a grease nipple on the gearbox. Use a grease
gun to top up with grease.This should be carried out after
approximately every 50 working hours. Use Husqvarna
special grease.
Pump in grease until clean grease emerges to the blades.
Cleaning and lubrication
Clean any resin and plant residue from the blades using
cleaning agent before and after using the machine.
Lubricate the blade bars with special grease before long
periods of storage.
IMPORTANT! Use only HUSQVARNA replacement
parts. Use of other brands of replacement parts can
cause damage to your unit or injury to the operator or
others.Your warranty does not cover damage or liability
caused by the use of accessories and/or attachments
not specifically recommended by HUSQVARNA.
