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 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.

position then the carburettor idle setting must be adjusted.  
See instructions under the heading Maintenance.  
Vibration damping system  
Your machine is equipped with a vibration damping  
system that is designed to reduce vibration and make  
operation easier.  
Stop switch  
The machine′s vibration damping system reduces the  
transfer of vibration between the engine unit/cutting  
equipment and the machine′s handle unit.  
Use the stop switch to switch off the engine.  
Regularly check the vibration damping units for cracks or  
deformation. Check that the vibration damping element is  
undamaged and securely attached.  
Start the engine and make sure the engine stops when  
you move the stop switch to the stop setting.  
WARNING! Overexposure to vibration

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.  
(327HDA65, 327HE3)  
The hand guard prevents hands from coming into contact  
with the moving blades, for example, if the operator loses  
grip on the front handle.  
Muffler

GENERAL SAFETY PRECAUTIONS  
In countries that have a warm and dry climate there is a  
WARNING! Bear in mind that:  
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.  
!
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  
For mufflers it is very important that you follow the  
instructions on checking, maintaining and servicing your  
machine.  
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.  
Never use a machine that has a faulty muffler.  
Regularly check that the muffler is securely attached to  
the machine.  
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.  
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.  
Replace the blades if they are bent or damaged.  
Blade guard  
(327HDA65)  
The blade guard (A) is intended to protect against any  
part of the body coming into contact with the blades (B).  
WARNING! Mufflers fitted with catalytic  
converters get very hot during use and  
A
!
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.

2
If you have spilled fuel on it. Wipe off the spillage and  
allow remaining fuel to evaporate.  
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.  
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.  
Use low-emission gasoline, also known as alkylate  
gasoline, 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.  
This engine is certified to operate on unleaded  
gasoline.  
•
•
When storing and transporting fuel always use  
approved containers intended for this purpose.  
•
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 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.  
•
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.  
Mixing ratio

MAINTENANCE  
the optimal setting and should be maintained for the  
Carburetor  
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  
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 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  
The blades must also remain stationary when the choke  
control is in the start throttle position.  
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.  
Muffler  
•
•
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.  
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  
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.  
Basic setting

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  
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.  
1
The cooling system consists of:  
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.

Air intake on the starter.  
Fins on the flywheel.  
Cooling fins on the cylinder.  
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.  
CAUTION! Never use a machine with a defective muffler.  
Spark plug  
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.  
The spark plug condition is influenced by:  
•
•
Incorrect carburetor adjustment.  
Remember the risk of fire!  
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 0.020 inch (0.5

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.  
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.  
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.  
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.  
The grease in the bevel gear does not normally need to  
be changed except if repairs are carried out.  
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
