WARNING! Never use a machine with faulty
safety equipment. The machine’s safety
equipment must be checked and maintained
as described in this section. If your machine
fails any of these checks contact your
service agent to get it repaired.
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.
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.

GENERAL SAFETY PRECAUTIONS
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.
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.
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.
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.
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!
WARNING! The inside of the muffler contain
chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a
damaged muffler.
8 – English
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
(326HDA55)
The blade guard (A) is intended to protect against any part of
the body coming into contact with the blades (B).
A
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.

(326HDA55)
3 Slide the spacer into the slot in the loop handle.
4 Fit the nut and screw. Do not overtighten.
Fitting the cutting head
(326HDA55)
It is important that the hedge trimmer is laid on a flat surface
when you fit the cutting head. Otherwise the cutting head may
not be fitted straight.
1 Fit the cutting head to the shaft. CAUTION! Make sure the
drive shaft inside the shaft engages with the recess in the
cutting head.
2 Tighten the lower screw first, then the upper screw.
Adjusting the harness

5 Now make a final adjustment to give yourself a
comfortable working position. Tighten the screw.
CAUTION! The loop handle and hand guard must not be
fitted behind the arrow marked on the shaft.
Fitting the handle
(326HE3, 326HE4)
You should always use the harness with the machine to give
maximum control over the machine and reduce the risk of
fatigue in your arms and back.
1 Put on the harness.
2 Hook the machine onto the harness support hook.
3 Adjust the length of the harness so that the support hook
is roughly level with your right hip.
Fit the handle using two screws.
10 – English
ASSEMBLY
Fitting the impact guard
(326HE4)
Fit the guard using the three screws and washers. Fit the two
short screws in hole A. Tighten the screws to a torque of 4
Nm. After the machine has been in use for around 20 hours,
re-tighten the screws to 4 Nm.

FUEL HANDLING
Fuel safety
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 gas station to find out
where to dispose of excess fuel.
• 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.
• 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.
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and
!
inhaling fumes.
Fuel
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 twostroke engine oil, which is specially formulated for our aircooled 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
1:50 (2%) with HUSQVARNA two-stroke oil.
CAUTION! The machine is equipped with a two-stroke
engine and must always been 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.
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.

• 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
WARNING! Taking the following precautions,
will lessen the risk of fire:
!
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
Always stop the engine and let it cool for a
few minutes before refuelling.
When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
Tighten the fuel cap carefully after refuelling.
Always move the machine away from the
refuelling area before starting.
• 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.

manufactured to specifications that reduce harmful
emissions. After the engine has used 8-10 tanks of fuel the
engine will be run-in. To ensure that it continues to run at peak
performance and to minimise harmful exhaust emissions
after the running-in period, ask your dealer/service workshop
(who will have a rev counter at their disposal) to adjust your
carburettor.
WARNING! The complete clutch cover and
shaft must be fitted before the machine is
!
started, otherwise the clutch can come loose
and cause personal injury.
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.
• The carburetor has three adjustment controls:
L = Low speed jet
H = High speed jet
T = Idle adjustment screw
Basic setting
• The basic carburetor settings are adjusted during testing
at the factory. The basic setting is richer than the optimal
setting and should be maintained for the first few hours the
machine is in use. The carburettor should then be finely
adjusted. Fine adjustment should be carried out by a
skilled technician.
CAUTION! If the blades move while the engine is idling the T
screw should be turned anti-clockwise until they stop.
Rec. idle speed 2700 rpm
Recommended max. speed: See the Technical data section.
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.
Fine adjustment
• When the machine has been ”run-in” the carburetor
should be finely adjusted. The fine adjustment should
be carried out by a qualified person. First adjust the Ljet, then the idling screw T and then the H-jet.
Conditions
• Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted. If you adjust
the carburettor when the air filter is dirty it will result in a
leaner mixture when the filter is finally cleaned. This can
lead to serious engine damage.
• Carefully turn both jets, L and H, so that they are midway
between fully screwed in and fully screwed out.
• Do not attempt to adjust the L and H jets beyond either
stop as this could cause damage.
• Now start the machine according to the starting
instructions and let it warm up for 10 minutes.
CAUTION! If the blades move while the engine is idling the T
screw should be turned anti-clockwise until they stop.
• The L and H-jets are used to adjust the supply of fuel to
match the rate that air is admitted, which is controlled with
the throttle. If they are screwed clockwise the air/fuel ratio
becomes leaner (less fuel) and if they are turned anticlockwise the ratio becomes richer (more fuel). A lean
mixture gives a higher engine speed and a rich mixture
gives a lower engine 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.
18 – English
Low speed jet L
Try to find the highest idling speed, turning the low speed
needle L clockwise respectively counter-clockwise. When the
highest speed has been found, turn the low speed needle L 1/
4 turn counter-clockwise.
CAUTION! If the blades move while the engine is idling the T
screw should be turned anti-clockwise until they stop.
MAINTENANCE
Fine adjustment of the idle speed T
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.
IMPORTANT! 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.
High speed jet H
Correctly adjusted carburetor
When the carburetor is correctly adjusted the machine
accelerates without hesitation and burbles a little at maximum
speed. It is also important that the blades do not move when
the engine is idling or when the choke control is in the start
position. If the low speed jet L is set too lean it may cause
starting difficulties and poor acceleration.
If the high speed jet H is set too lean it will result in less power,
less performance, poor acceleration and/or damage to the
engine. If both the L and H jets are set too rich it will results in
acceleration problems or too low a working speed.
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.
The high speed jet H affects the engine power, speed,
temperature and fuel consumption. If the high speed jet H is
set too lean (screwed in too far) the engine speed will be too
high and cause engine damage. Do not let the engine run at
full speed for more than 10 seconds.
Apply full throttle and turn the high speed jet H very slowly
clockwise until the engine slows down. Then turn the high
speed jet H very slowly anticlockwise until the engine starts to
run unevenly. Now turn the high speed jet H slowly clockwise
a little way until the engine runs smoothly.
Note that the engine should not be under load when you
adjust the high speed jet H. The high speed jet H is adjusted
correctly when the machine burbles a little. If the machine
races then the setting is too lean. If the engine produces a lot
of smoke and burbles a lot then the setting is too rich.
H
Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done with a
wire brush.
On mufflers without a catalytic converter the mesh should be
cleaned weekly, or replaced if necessary. On mufflers fitted
with a catalytic converter the mesh should be checked, and if
necessary cleaned, monthly. If the mesh is damaged it
should be replaced. If the mesh 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 mesh will cause the machine to overheat and result
in damage to the cylinder and piston. See also instructions
under the heading Maintenance.
CAUTION! Never use a machine with a defective muffler.
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
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!

MAINTENANCE
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
4
3
2
1
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).
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 0.5 mm (0,020"). The spark plug
should be replaced after about a month in operation or earlier
if necessary.
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.
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 distribute 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.
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.
20 – English
MAINTENANCE
Gear housing
There is a grease nipple and a plug 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
special grease, no. 503 98 96-01.
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 bevel gear does not normally need to be
changed except if repairs are carried out.
Cleaning and lubrication
Clean any resin and plant residue from the blades using
cleaning agent 531 00 75-13 (UL22) before and after using
the machine.
Lubricate the blade bars with special grease,
part no. 531 00 75-12 (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.
