INTRODUCTION  
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 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. Husqvarnas 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  
operators manual as a valuable document. By following itscontent (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 operators 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.

Machine s safety equipment  
This section describes the machines safety equipment,  
its purpose, and how checks and maintenance should be  
carried out to ensure that it operates correctly. See the  
”What is what?” section to locate where this equipment is  
positioned on your machine.  
The life span of the machine can be reduced and the risk  
of accidents can increase if machine maintenance is not  
carried out correctly and if service and/or repairs are not  
carried out professionally. If you need further information  
please contact your nearest service workshop.  
Press the throttle lockout and make sure it returns to its  
original position when you release it.  
IMPORTANT!  
All servicing and repair work on the machine requires  
special training.This is especially true of the machines  
safety equipment.If your machine fails any of the checks  
described below you must contact your service agent.  
When you buy any of our products we guarantee the  
availability of professional repairs and service. If the  
retailer who sells your machine is not a servicing dealer,  
ask him for the address of your nearest service agent.  
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

GENERAL SAFETY PRECAUTIONS  
Regularly check the vibration damping units for cracks or  
deformation. Check that the vibration damping element is  
undamaged and securely attached.  
Stop switch  
Use the stop switch to switch off the engine.  
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.  
Start the engine and make sure the engine stops when  
you move the stop switch to the stop setting.  
Muffler  
Hand guard  
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.  
The hand guard prevents hands from coming into contact  
with the moving blades, for example, if the operator loses  
grip on the front handle.  
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.  
Check that the hand guard is fitted correctly.  
Check that the hand guard is undamaged.  
Vibration damping system  
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.  
Your machine is equipped with a vibration damping  
system that is designed to minimize vibration and make  
operation easier.  
The machines vibration damping system reduces the  
transfer of vibration between the engine unit/cutting  
equipment and the machines handle unit. The engine  
body including the blades is suspended on the handlebar  
system via a four springs.  
For mufflers it is very important that you follow the  
instructions on checking, maintaining and servicing your  
machine.  
8 – English  
 
GENERAL SAFETY PRECAUTIONS  
Never use a machine that has a faulty muffler.  
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.  
Check that the blades are undamaged and show no signs  
of cracking or other damage.  
Blade guard  
Regularly check that the muffler is securely attached to  
the machine.  
The blade guard (A) is intended to protect against any  
part of the body coming into contact with the blades (B).  
A
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!  
B
Check that the blade guard is not damaged or distorted.  
Replace the blade guard if it is bent or damaged.  
WARNING! The inside of the muffler  
contain chemicals that may be  
!
carcinogenic. Avoid contact with these  
elements in the event of a damaged  
muffler.  
Gear  
The gear housing gets hot when the machine has been in  
use. To avoid burning yourself do not touch the gear  
housing.  
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!  
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.

FUEL HANDLING  
Petrol  
Fuel safety  
Never start the machine:  
1
2
If you have spilt fuel on it. Wipe off the spillage and  
allow remaining fuel to evaporate.  
CAUTION! Always use a quality petrol/oil mixture at least  
90 octane (RON). If your machine is equipped with a  
catalytic converter (see chapter onTechnical data) always  
use a good quality unleaded petrol/oil mixture. Leaded  
petrol will destroy the catalytic converter.  
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.  
Use low-emission petrol, also known as alkylate petrol, if  
it is available.  
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.  
The lowest octane recommended 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, which can result in serious  
engine damage.  
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.  
Ensure the machine is cleaned and that a complete  
service is carried out before long-term storage.  
When working at continuous high revs a higher octane  
rating is recommended.  
The transport guard must always be fitted to the  
cutting attachment when the machine is being  
transported or in storage.  
Two-stroke oil  
Secure the machine during transport.  
For best results and performance use HUSQVARNA  
two-stroke engine oil, which is specially formulated for  
our air-cooled two-stroke engines.  
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.  
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.  
WARNING!Take care when handling fuel.  
Bear in mind the risk of fire, explosion  
and inhaling fumes.  
A poor oil quality and/or too high oil/fuel ratio may  
jeopardise function and decrease the life time of  
catalytic converters.  
!
Mixing ratio  
Fuel  
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  
petrol and two-stroke 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.

FUEL HANDLING  
Fuelling  
Mixing  
Always mix the petrol and oil in a clean container  
intended for fuel.  
Always start by filling half the amount of the petrol to  
be used. Then add the entire amount of oil. Mix  
(shake) the fuel mixture. Add the remaining amount of  
petrol.  
WARNING! Taking the following  
precautions, will lessen the risk of fire:  
!
Mix (shake) the fuel mixture thoroughly before filling  
the machine’s fuel tank.  
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.  
Do not mix more than one month’s supply of fuel at a  
time.  
Always use a fuel container with an anti-spill valve.  
If the machine is not used for some time the fuel tank  
should be emptied and cleaned.  
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.

face away from the hedge.  
Hold the machine as close to your body as possible to  
get the best balance.  
Watch out for stumps of branches that can be thrown  
out during cutting.  
Do not cut too close to the ground. Stones and other  
objects can be thrown out.  
Check the working area for foreign objects such as  
electricity cables, insects and animals, etc, or other  
objects that could damage the cutting attachment,  
such as metal items.  
If any foreign object is hit or if vibrations occur stop the  
machine immediately. Disconnect the HT lead from  
the spark plug. Check that the machine is not  
damaged. Repair any damage.  
If anything jams in the blades while you are working,  
switch off the engine and wait until it has stopped  
completely before cleaning the blades.Disconnect the  
HT lead from the spark plug.  
Make sure that the tip does not touch the ground.  
Watch out for plant material that attaches to or around  
the exhaust pipe, to avoid the risk of fire.  
Do not rush the work, but work steadily until all the  
branches have been cut back cleanly.  
Avoid using the hedge trimmers upside down on top of  
the hedge. Risk of damage to the hedge due to the  
exhaust fumes.  
(325HD60, 325HD75)  
The hedge trimmer’s rear handle can be set in three  
positions by pulling out the catch. See figure. When  
the handle is adjusted the hedge trimmer should be  
idling or not running.  
Never put the machine down with the engine running  
unless you have it in clear sight.  
Safety instructions after completing work  
The transport guard should always be fitted to the  
cutting attachment when the machine is not in use.  
Make sure the cutting attachment has stopped before  
cleaning, carrying out repairs or an inspection.  
Disconnect the HT lead from the spark plug.  
While working the handle should always be facing  
upwards irrespective of how the hedge trimmer is  
directed.  
Always wear heavy-duty gloves when repairing the  
cutting attachment. This is extremely sharp and can  
easily cause cuts.  
Store the machine out of reach of children.  
Use only original spare parts for repairs.  
Basic working techniques  
Work with a swinging action from the bottom upwards  
when trimming sides.  
Adjust the throttle setting to suit the load.

MAINTENANCE  
the optimal setting and should be maintained for the  
Carburettor  
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.  
Your Husqvarna product has been designed and  
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.  
CAUTION! If the blades move while the engine is idling  
the T screw should be turned anti-clockwise until they  
stop.  
Adjustment of the idle speed  
Before any adjustments are made, make sure that the air  
filter is clean and the air filter cover is fitted.  
Function  
Adjust the idle speed with the idle adjustment screw T, if  
adjustment is necessary. First turn the idle adjustment  
screwT 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.  
The carburettor governs the engine’s speed via the  
throttle control. Air and fuel are mixed in the  
carburettor. The air/fuel mixture is adjustable. Correct  
adjustment is essential to get the best performance  
from the machine.  
Adjusting the carburettor means that the engine is  
adapted to local operating conditions, e.g. climate,  
altitude, petrol and the type of 2-stroke oil.  
The carburettor has three adjustment controls:  
L = Low speed jet  
H = High speed jet  
T = Idle adjustment screw  
Rec. idle 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.  
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 anti-clockwise the ratio  
becomes richer (more fuel). A lean mixture gives a  
higher engine speed and a rich mixture gives a lower  
engine 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 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.  
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

material.  
Cooling system  
To keep the working temperature as low as possible the  
machine is equipped with a cooling system.  
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.  
The cooling system consists of:

4
Air intake on the starter.  
Fins on the flywheel.  
Cooling fins on the cylinder.  
Cylinder cover (directs cold air over the cylinder).  
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

system results in the machine overheating which causes  
damage to the piston and cylinder.

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.  
CAUTION! Never use a machine with a defective muffler  
or exhaust pipe.  
The spark plug condition is influenced by:  
Incorrect carburettor adjustment.  
An incorrect fuel mixture (too much or incorrect type of  
oil).  
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!  
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. The  
spark plug should be replaced after about a month in  
operation or earlier if necessary.

MAINTENANCE  
CAUTION! Always use the recommended spark plug  
use common engine oil.This would drain through the filter  
quite quickly and collect in the bottom.  
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:  
Gear  
Carburettor malfunctions  
Starting problems  
Loss of engine power  
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.  
Unnecessary wear to engine parts.  
Excessive fuel consumption.  
Clean the filter every 25 hours, or more regularly if  
conditions are exceptionally dusty.  
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.  
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.  
The grease in the bevel gear does not normally need to  
be changed except if repairs are carried out.  
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.  
Cleaning and lubrication  
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.  
Clean any resin and plant residue from the blades using  
cleaning agent 531 00 75-13 (UL22) before and after  
using the machine.  
Oiling the air filter  
Lubricate the blade bars with special grease, part no. 531  
00 75-12 (UL 21) before long periods of storage.  
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
