INTRODUCTION
1141324-49 Rev. 1 2019-04-19
Dear customer!
Congratulations 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 pr
ior
ity. 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 author
ized 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
appear
ance of products without pr
ior notice.

Stop switch
Use the stop switch to switch off the engine.
Start the engine and make sure the engine stops when
y
ou move the stop switch to the stop setting.
Hand guard
The hand guard prevents 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.
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.
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 r
isk 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.
!
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
1141324-49 Rev. 1 2019-04-19
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 screen this m
ust be cleaned regularly. A blocked
screen will cause the engine to overheat and may lead to
serious damage.
Blades
The edges of the blades are too hard to be filed. Dull
blades should be sharpened using a grinder.
Bent or damaged blades must be changed.
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.
Bent or damaged b
lade guards must be changed.
Gear
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear
housing.
!
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.

FUEL HANDLING
English 11
1141324-49 Rev. 1 2019-04-19
Fuel safety
Never start the machine:
1 If you have spilled fuel on it. Wipe off the spillage and
allo
w remaining fuel to evaporate.
2 If you have spilled fuel on yourself or your clothes,
change y
our 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
. In the event of
leakage, contact your service agent.
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
appro
ved 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 the tank into
the appropriate containers and in a well ventilated area.
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
tr
ansported 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.
Allow the hedge trimmer to cool down after use before
putting it away for storage.
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.
Ethanol blended fuel, E10 may be used (max 10%
ethanol b
lend). Using ethanol blends higher than E10 will
create lean running condition which can cause engine
damage.
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
r
ating 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.
!
WARNING! Always ensure there is
adequate ventilation when handling fuel.

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
If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
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:
Mix and pour fuel outdoors, where there
are no sparks or flames.

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.
Recommended 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 e
xhaust 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.
The net on the catalyzer muffler must be checked and if
necessar
y cleaned once a month. Use a wire brush.
If the
mesh is damaged it must 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! 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 Air intake on the starter.
2 Fins on the flywheel.
3 Cooling fins on the cylinder.
4 Cylinder cover (directs cold air over the cylinder).
5 Muffler cover
6 Muffler plate
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
poor
ly 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 0.026 inch
(0.65 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. See the Technical data section.
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 e
xceptionally dusty.

Cleaning the air filter
Close the choke control by setting the choke into a choke
position.
Remove the air filter cover and take out the filter. Wash it
clean in w
arm, 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.
If the machine is used in dusty conditions the air filter
should be soaked in oil. See instructions under the
heading Oiling the air filter.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48.
The filter oil contains a solvent to make it spread evenly
through the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distr
ibute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine. Never
use common engine oil. This would drain through the filter
quite quickly and collect in the bottom.
Gear
There is a grease nipple for filling lubricant on the gear
housing. Use a grease gun to fill with grease. This should
be done after every 60 working hours. Use Husqvarna’s
gear grease - hedge trimmer.
CAUTION! The gear housing must not be filled
completely with grease. The grease expands as the
machine heats up during operation. If the gear housing
was completely filled with grease it could damage the
seals and lead to leakage of grease.
The grease in the gear house does not normally need to
be changed e
xcept if repairs are carried out.
Cleaning and lubrication
Clean any resin and plant residue from the blades using
Husqvarna cleaning agent (UL22) before and after using
the machine.
Lubricate the blade bars with husqvarnas special grease,
par
t no. (UL 21) 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.
