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 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 ever lend or sell this machine, make sure that the borrower or buyer gets the operators  
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.

GENERAL SAFETY PRECAUTIONS  
Important  
Personal protective equipment  
IMPORTANT!  
IMPORTANT!  
The machine is only designed for trimming grass, grass  
clearing and/or forestry clearing.  
A clearing saw, brushcutter or trimmer can be dangerous if  
used incorrectly or carelessly, and can cause serious or  
fatal injury to the operator or others. It is extremely  
important that you read and understand the contents of this  
operator’s manual.  
The only accessories you can operate with this engine unit  
are the cutting attachments we recommend in the chapter  
on Technical data.  
You must use approved personal protective equipment  
whenever you use the machine. Personal protective  
equipment cannot eliminate the risk of injury but it will  
reduce the degree of injury if an accident does happen. Ask  
your dealer for help in choosing the right equipment.  
Never use the machine if you are tired, if you have drunk  
alcohol, or if you are taking medication that could affect your  
vision, your judgement or your co-ordination.  
Wear personal protective equipment. See instructions  
under the heading Personal protective equipment.  
Never use a machine that has been modified in any way  
from its original specification.  
WARNING! Listen out for warning signals or  
shouts when you are wearing hearing  
protection. Always remove your hearing  
protection as soon as the engine stops.  
!
Never use a machine that is faulty. Carry out the checks,  
maintenance and service instructions described in this  
manual.Some maintenance and service measures must be  
carried out by trained and qualified specialists. See  
instructions under the heading Maintenance.  
HELMET  
A helmet should be worn if the trees being cleared are taller  
than 2 m.  
All covers, guards and handles must be fitted before  
starting. Ensure that the spark plug cap and ignition lead  
are undamaged to avoid the risk of electric shock.  
The machine operator must ensure that no people or  
animals come closer than 15 metres while working. When  
several operators are working in the same area the safety  
distance should be at least twice the tree height and no less  
than 15 metres.  
HEARING PROTECTION  
Wear hearing protection that provides adequate noise  
reduction.  
WARNING! The ignition system of this  
machine produces an electromagnetic field  
during operation.This field may under some

Press the throttle lockout and make sure it returns to its  
original position when you release it.  
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.  
Check that the throttle control and throttle lockout move freely  
and that the return springs work properly.  
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 servicing dealer.  
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

GENERAL SAFETY PRECAUTIONS  
Regularly check the vibration damping units for cracks or  
deformation. Check that the vibration damping element is  
undamaged and securely attached.  
Cutting attachment guard  
WARNING! Overexposure to vibration can  
lead to circulatory damage or nerve damage  
in people who have impaired circulation.  
This guard is intended to prevent loose objects from being  
thrown towards the operator. The guard also protects the  
operator from accidental contact with the cutting attachment.  
!
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.  
Check that the guard is undamaged and not cracked.Replace  
the guard if it has been exposed to impact or is cracked.  
Quick release  
There is an easily accessible, quick release fitted at the front  
as a safety precaution in case the engine catches fire, or in  
any other situation that requires you to free yourself from the  
machine and harness. See instructions under the heading  
Adjusting the harness and clearing saw.  
Always use the recommended guard for the cutting  
attachment you are using. See chapter on Technical data.  
WARNING! Never use a cutting attachment  
without an approved guard. See the chapter  
on Technical data. If an incorrect or faulty  
guard is fitted this can cause serious  
personal injury.  
!
Vibration damping system  
Check that the harness straps are correctly positioned. Once  
the harness and machine have been adjusted, check that the  
harness quick release works correctly.  
Your machine is equipped with a vibration damping system  
that is designed to reduce vibration and make operation  
easier.  
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.  
Using incorrectly wound cord or a blunt or incorrect cutting  
attachment (wrong type or incorrectly filed, see instructions  
under the heading Filing the blade) increases the level of  
vibration.  
The machines vibration damping system reduces the transfer  
of vibration between the engine unit/cutting equipment and  
the machines handle unit.  
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.

GENERAL SAFETY PRECAUTIONS  
Never use a machine that has a faulty muffler.  
Locking nut  
A locking nut is used to secure some types of cutting  
attachment.  
Regularly check that the muffler is securely attached to the  
machine.  
When fitting, tighten the nut in the opposite direction to the  
direction of rotation of the cutting attachment. To remove it,  
undo the nut in the same direction as the cutting attachment  
rotates. (CAUTION! The nut has a left-hand thread.) Tighten  
the nut using the socket spanner.  
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!  
When loosening and tightening the saw blade nut, there is a  
risk of injury from the teeth of the saw blade.You should  
therefore always ensure that your hand is shielded by the  
blade guard when doing this. Always use a socket spanner  
with a shaft that is long enough to allow this.The arrow in the  
diagram shows the area where you should operate the socket  
spanner when loosening or tightening the nut.  
!
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!  
The nylon lining inside the locking nut must not be so worn  
that you can turn it by hand. The lining should offer a  
resistance of at least 1.5 Nm. The nut should be replaced  
after it has been put on approx. 10 times.

GENERAL SAFETY PRECAUTIONS  
General rules  
Cutting equipment  
This section describes how to choose and maintain your  
cutting equipment in order to:  
Reduce the risk of blade thrust.  
Only use cutting attachments with the guards we  
recommend! See the chapter on Technical data.  
Obtain maximum cutting performance.  
Extend the life of cutting equipment.  
IMPORTANT!  
Only use cutting attachments with the guards we  
recommend! See the chapter on Technical data.  
Keep the teeth of the blade correctly sharpened! Follow our  
instructions and use the recommended file gauge. An  
incorrectly sharpened or damaged blade increases the risk of  
accidents.  
Refer to the instructions for the cutting attachment to check  
the correct way to load the cord and the correct cord  
diameter.  
Keep the teeth of the blade correctly sharpened! Follow our  
recommendations. Also refer to the instructions on the  
blade packaging.  
Maintain the correct blade setting! Follow our instructions  
and use the recommended file gauge.  
Keep the correct setting on the saw blade! Follow our  
instructions and use the recommended setting tool. An  
incorrectly set saw blade increases the risk of jamming and  
blade thrust, and damage to the saw blade.  
WARNING! Always stop the engine before  
doing any work on the cutting attachment.  
This continues to rotate even after the  
throttle has been released. Ensure that the  
cutting attachment has stopped completely  
and disconnect the HT lead from the spark  
plug before you start to work on it.  
!
Check the cutting attachment for damage or cracks. A  
damaged cutting attachment should always be replaced.  
WARNING! Using an incorrect cutting  
attachment or an incorrectly sharpened  
blade increases the risk of blade thrust.  
!
Cutting equipment  
Saw blades are intended for cutting fibrous types of wood.  
Sharpening grass cutters and grass  
blades  
Grass blades and grass cutters are intended for cutting  
coarse grass.  
See the cutting attachment packaging for correct  
sharpening instructions. Sharpen blades and cutters  
using a single-cut flat file.  
Sharpen all edges equally to maintain the balance of the  
blade.  
A trimmer head is intended for trimming grass.  
WARNING! Always discard a blade that is  
bent, twisted, cracked, broken or damaged  
in any other way. Never attempt to straighten  
a twisted blade so that it can be reused. Only  
use original blades of the specified type.

GENERAL SAFETY PRECAUTIONS  
Sharpening the saw blade  
Trimmer head  
IMPORTANT!  
Always ensure the trimmer cord is wound tightly and evenly  
around the drum, otherwise the machine will generate  
harmful vibration.  
See the cutting attachment packaging for correct  
sharpening instructions.  
A correctly sharpened blade is essential for working efficiently  
and to avoid unnecessary wear to the blade and clearing saw.  
Only use the recommended trimmer heads and trimmer  
cords.These have been tested by the manufacturer to suit  
a particular engine size.This is especially important when  
a fully automatic trimmer head is used. Only use the  
recommended cutting attachment. See the chapter on  
Technical data.  
Smaller machines generally require small trimmer heads  
and vice versa. This is because when clearing using a  
cord the engine must throw out the cord radially from the  
trimmer head and overcome the resistance of the grass  
being cleared.  
Make sure that the blade is well supported when you file  
it. Use a 5.5 mm round file with a file holder.  
The length of the cord is also important. A longer cord  
requires greater engine power than a shorter cord of the  
same diameter.  
Make sure that the cutter on the trimmer guard is intact.  
This is used to cut the cord to the correct length.  
The filing angle is 15°. File alternate teeth to the right and  
those in between to the left. If the blade has been heavily  
pitted by stones it may be necessary to dress the top  
edges of the teeth with a flat file, in exceptional cases. If  
so, this should be done before filing with a round file. The  
top edges must be filed down by the same amount for all  
the teeth.  
To increase the life of the cord it can be soaked in water  
for a couple of days.This will make the line tougher so that  
it lasts longer.  
Adjust the blade setting. This should be 1 mm.

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 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.

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.  
When storing and transporting fuel always use approved  
containers intended for this purpose.  
This engine is certified to operate on unleaded gasoline.  
The lowest recommended octane grade is 87  
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.  
((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.  
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  
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.  
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).  
WARNING! Take care when handling fuel.  
Bear in mind the risk of fire, explosion and  
inhaling fumes.  
!
Never use oil intended for four-stroke engines.  
Mixing ratio  
1:50 (2%) with HUSQVARNA two-stroke oil.  
Fuel  
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.

FUEL HANDLING  
Mixing  
Fueling  
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.  
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.  
Clean the area around the fuel cap. Contamination in the  
tank can cause operating problems.  
If the machine is not used for some time the fuel tank  
should be emptied and cleaned.  
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 vapours.

STARTING AND STOPPING  
Check before starting  
Starting and stopping  
Check the blade to ensure that no cracks have formed at  
the bottom of the teeth or by the centre hole. The most  
common reason why cracks are formed is that sharp  
corners have been formed at the bottom of the teeth while  
sharpening or that the blade has been used with dull  
teeth. Discard a blade if cracks are found.  
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.  
!
Always move the machine away from the  
refuelling area before starting. Place the  
machine on a flat surface. Ensure the cutting  
attachment cannot come into contact with  
any object.  
Make sure no unauthorised persons are in  
the working area, otherwise there is a risk of  
serious personal injury.The safety distance  
is 15 metres.  
Check that the support flange is not cracked due to fatigue  
or due to being tightened too much. Discard the support  
flange if it is cracked.  
Starting  
Primer bulb: Press the air purge repeatedly until fuel begins  
to fill the bulb. The bulb need not be completely filled.  
Ensure the locking nut has not lost its captive force. The  
nut lock should have a locking force of at least 1.5 Nm.  
The tightening torque of the locking nut should be 35-50  
Nm.  
Check that the blade guard is not damaged or cracked.  
Replace the blade guard if it is exposed to impact or is  
cracked.  
Choke: Set the choke control in the choke position.  
Check that the trimmer head and trimmer guard are not  
damaged or cracked. Replace the trimmer head or  
trimmer guard if they have been exposed to impact or are  
cracked.  
WARNING! When the engine is started with  
the choke in either the choke or start throttle  
positions the cutting attachment will start to  
rotate immediately.  
!
Hold the body of the machine on the ground using your left  
hand (CAUTION! Not with your foot!). Grip the starter handle,  
slowly pull out the cord with your right hand until you feel  
some resistance (the starter pawls grip), now quickly and  
powerfully pull the cord.Never wrap the starter cord around  
your hand  
Repeat pulling the cord until the engine starts. When the  
engine starts. return choke control to run position and apply  
full throttle; the throttle will automatically disengage from the  
start setting.  
Never use the machine without a guard nor with a  
defective guard.  
All covers must be correctly fitted and undamaged before  
you start the machine.

STARTING AND STOPPING  
CAUTION! Do not pull the starter cord all the way out and do  
not let go of the starter handle when the cord is fully extended.  
This can damage the machine.  
Stopping  
Stop the engine by switching off the ignition.  
CAUTION! Do not put any part of your body in marked area.  
Contact can result in burns to the skin, or electrical shock if  
the spark plug cap has been damaged. Always use gloves.  
Do not use a machine with damaged spark plug cap.  
CAUTION! The stop switch automatically returns to the start  
position. In order to prevent unintentional starting, the spark  
plug cap must be removed from the spark plug when  
assembling, checking and/or performing maintenance.  
For throttle handles with a start throttle  
lock:  
Set the throttle to the start position by first pressing the throttle  
lockout and the throttle trigger, then pressing the start throttle  
button (A). Then release the throttle lockout and the throttle  
trigger, followed by the start throttle button. The throttle  
function is now activated. To return the engine to idle, press  
the throttle lockout and throttle trigger again.  
PART THROTTLE FUNCTION (RX, RDX):  
It is possible to set the engine for part throttle operation using  
the dial on the side of the throttle handle. Turn the dial up to  
decrease the part throttle rpm.Turn the dial down to increase  
the part throttle rpm.When you have set the part throttle rpm  
you will feel increased resistance when you press the throttle  
trigger.This increased resistance makes it easier to maintain  
a constant part throttle setting.To obtain full throttle, press the  
throttle trigger a little harder so that it goes past the part  
throttle setting. As soon as you release the throttle trigger the  
engine will return to idle. The part throttle function does not  
lock the engine at a given rpm, it is simply a brake that makes  
it easier to maintain the engine at a given rpm.

Keep a good balance and a firm foothold.  
General working instructions  
Always hold the machine with both hands. Hold the  
machine on the right side of your body.  
IMPORTANT!  
This section describes the basic safety precautions for  
working with clearing saws and trimmers.  
If you encounter a situation where you are uncertain how to  
proceed you should ask an expert. Contact your dealer or  
your service workshop.  
Avoid all usage which you consider to be beyond your  
capability.  
You must understand the difference between forestry  
clearing, grass clearing and grass trimming before use.

9
Keep the cutting attachment below waist level.  
Basic safety rules  
Switch off the engine before moving to another area. Fit  
the transport guard before carrying or transporting the  
equipment any distance.  
10 Never put the machine down with the engine running  
unless you have it in clear sight.  
1
Look around you:  
To ensure that people, animals or other things cannot  
affect your control of the machine.  
The ABC of clearing  
To ensure that people, animals, etc., do not come into  
contact with the cutting attachment or loose objects that  
are thrown out by the cutting attachment.  
Always use the correct equipment.  
Make sure the equipment is well adjusted.  
Follow the safety precautions.  
CAUTION! Do not use the machine unless you are able to  
call for help in the event of an accident.  
Organise your work carefully.  
2
Inspect the working area. Remove all loose objects, such  
as stones, broken glass, nails, steel wire, string, etc. that  
could be thrown out or become wrapped around the  
cutting attachment.  
Always use full throttle when starting to cut with the blade.  
Always use sharp blades.  
Avoid stones.  
3
4
Do not use the machine in bad weather, such as dense  
fog, heavy rain, strong wind, intense cold, etc. Working in  
bad weather is tiring and often brings added risks, such as  
icy ground, unpredictable felling direction, etc.  
Control the felling direction (take advantage of the wind).  
WARNING! Neither the operator of the  
machine nor anyone else may attempt to  
remove the cut material while the engine is  
running or the cutting equipment is rotating,  
as this can result in serious injury.  
Make sure you can move and stand safely.Check the area  
around you for possible obstacles (roots, rocks, branches,  
ditches, etc.) in case you have to move suddenly. Take  
great care when working on sloping ground.  
!
Stop the engine and cutting equipment  
before you remove material that has wound  
around the blade shaft as otherwise there is  
a risk of injury.The bevel gear can get hot  
during use and may remain so for a while  
afterwards.You could get burnt if you touch  
it.  
WARNING! Watch out for thrown objects.  
Always wear approved eye protection. Never  
lean over the cutting attachment guard.  
Stones, rubbish, etc. can be thrown up into  
the eyes causing blindness or serious injury.  
5
Take great care when cutting a tree that is under tension.  
A tree that is under tension may spring back to its normal  
position before or after being cut. If you position yourself  
incorrectly or make the cut in the wrong place the tree may  
hit you or the machine and cause you to lose control. Both  
situations can cause serious personal injury.  
!
Keep unauthorised persons at a distance.  
Children, animals, onlookers and helpers  
should be kept outside the safety zone of 15  
m. Stop the machine immediately if anyone  
approaches. Never swing the machine  
around without first checking behind you to  
make sure no-one is within the safety zone.

ditches or other obstacles on the ground.You should also  
orient the strip to take advantage of wind conditions, so  
that cleared stems fall in the cleared area of the stand.  
!
Working methods  
WARNING! Machines fitted with saw blades  
or grass blades can be thrown violently to  
the side when the blade comes into contact  
with a fixed object.This is called blade  
thrust. A blade thrust can be violent enough  
to cause the machine and/or operator to be  
propelled in any direction, and possibly lose  
control of the machine. Blade thrust can  
occur without warning if the machine snags,  
stalls or binds. Blade thrust is more likely to  
occur in areas where it is difficult to see the  
material being cut.  
!
Forestry clearing using a saw blade  
The risk of blade thrust increases with increasing stem  
size.You should therefore avoid cutting with the area of  
the blade between 12 o’clock and 3 o’clock.  
Avoid cutting with the area of the blade  
between the 12 o’clock and 3 o’clock  
positions. Because of the speed of rotation  
of the blade, blade thrust can occur if you  
attempt to cut thick stems with this area of  
the blade.  
Before you start clearing, check the clearing area, the  
type of terrain, the slope of the ground, whether there are  
stones, hollows etc.  
To fell to the left, the bottom of the tree should be pushed  
to the right. Tilt the blade and bring it diagonally down to  
the right, exerting firm pressure. At the same time push  
the stem using the blade guard. Cut with the area of the  
blade between 3 o’clock and 5 o’clock. Apply full throttle  
before advancing the blade.  
Start at whichever end of the area is easiest, and clear an  
open space from which to work.  
Work systematically to and fro across the area, clearing a  
width of around 4-5 m on each pass. This exploits the full  
reach of the machine in both directions and gives the  
operator a convenient and varied working area to work in.  
To fell to the right, the bottom of the tree should be pushed  
to the left. Tilt the blade and bring it diagonally up to the  
right. Cut with the area of the blade between 3 o’clock and  
5 o’clock so that the direction of rotation of the blade  
pushes the bottom of the tree to the left.  
Clear a strip around 75 m long. Move your fuel can as  
work progresses.  
On sloping ground you should work along the slope. It is  
much easier to work along a slope than it is to work up and  
down it.

WORKING TECHNIQUES  
To fell a tree forwards, the bottom of the tree should be  
pulled backwards. Pull the blade backwards with a quick,  
firm movement.  
and cut from the centre of the group. If it is still difficult to  
gain access, cut the stems high up and let them fall. This  
will reduce the risk of jamming.  
Large stems must be cut from two sides. First determine  
which direction the stem will fall. Make the first cut on the  
felling side. Then finish cutting the stem from the other  
side. Adjust the cutting pressure to match the size of the  
stem and the hardness of the wood. Small stems require  
more pressure, while large stems require less pressure.  
Grass clearing using a grass blade  
Grass blades and grass cutters must not be used on  
woody stems.  
A grass blade is used for all types of tall or coarse grass.  
The grass is cut down with a sideways, swinging  
movement, where the movement from right-to-left is the  
clearing stroke and the movement from left-to-right is the  
return stroke. Let the left-hand side of the blade (between  
8 and 12 o’clock) do the cutting.  
If the stems are tightly packed, adapt your walking pace to  
suit.  
If the blade jams in a stem, never jerk the machine free. If  
you do this the blade, bevel gear, shaft or handlebar may  
be damaged. Release the handles, grip the shaft with  
both hands and gently pull the machine free.  
If the blade is angled to the left when clearing grass, the  
grass will collect in a line, which makes it easier to collect,  
e.g. by raking.  
Try to work rhythmically. Stand firmly with your feet apart.  
Move forward after the return stroke and stand firmly  
again.  
Brush cutting with a saw blade  
Let the support cup rest lightly against the ground. It is  
used to protect the blade from hitting the ground.  
Thin stems and brush are mown down. Work with a  
sawing movement, swinging sideways.  
Reduce the risk of material wrapping around the blade by  
following these instructions:  
Try to cut several stems in a single sawing movement.  
1
2
Always work at full throttle.  
With groups of hardwood stems, first clear around the  
group. Start by cutting the stems high up around the  
outside of the group to avoid jamming.Then cut the stems  
to the required height. Now try to reach in with the blade  
Avoid the previously cut material during the return  
stroke.  
Stop the engine, unclip the harness and place the  
machine on the ground before you start to collect the cut  
material.

WORKING TECHNIQUES  
Sweeping  
Grass trimming with a trimmer head  
The fan effect of the rotating cord can be used for quick  
and easy clearing up. Hold the cord parallel to and above  
the area to be swept and move the tool to and fro.  
Trimming  
Hold the trimmer head just above the ground at an angle.  
It is the end of the cord that does the work. Let the cord  
work at its own pace. Never press the cord into the area  
to be cut.  
When cutting and sweeping you should use full throttle to  
obtain the best results.  
The cord can easily remove grass and weeds up against  
walls, fences, trees and borders, however it can also  
damage sensitive bark on trees and bushes, and damage  
fence posts.  
Reduce the risk of damaging plants by shortening the  
cord to 10-12 cm and reducing the engine speed.  
Clearing  
The clearing technique removes all unwanted vegetation.  
Keep the trimmer head just above the ground and tilt it.Let  
the end of the cord strike the ground around trees, posts,  
statues and the like. CAUTION! This technique increases  
the wear on the cord.  
The cord wears quicker and must be fed forward more  
often when working against stones, brick, concrete, metal  
fences, etc., than when coming into contact with trees and  
wooden fences.  
When trimming and clearing you should use less than full  
throttle so that the cord lasts longer and to reduce the  
wear on the trimmer head.  
Cutting  
The trimmer is ideal for cutting grass that is difficult to  
reach using a normal lawn mower. Keep the cord parallel  
to the ground when cutting. Avoid pressing the trimmer  
head against the ground as this can ruin the lawn and  
damage the tool.  
Do not allow the trimmer head to constantly come into  
contact with the ground during normal cutting. Constant  
contact of this type can cause damage and wear to the  
trimmer head.

MAINTENANCE  
CAUTION! If the cutting attachment rotates when the engine  
is idling the idle adjustment screw T should be turned anti-  
clockwise until the cutting attachment stops.  
Carburetor  
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.  
Rec. idle speed 2700 rpm  
Recommended max. speed: See theTechnical 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.  
!
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.  
!
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 L-  
jet, then the idling screw T and then the H-jet.  
Function  
Conditions  
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.  
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.  
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.  
Carefully turn both jets, L and H, so that they are midway  
between fully screwed in and fully screwed out.  
The carburetor has three adjustment controls:  
L = Low speed jet  
Do not attempt to adjust the L and H jets beyond either  
stop as this could cause damage.  
H = High speed jet  
Now start the machine according to the starting  
instructions and let it warm up for 10 minutes.  
T = Idle adjustment screw  
CAUTION! If the cutting attachment rotates when the  
engine is idling the idle adjustment screw T should be  
turned anti-clockwise until the cutting attachment stops.  
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.  
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.  
+ 1/4  
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.  
L
CAUTION! If the cutting attachment rotates when the engine  
is idling the idle adjustment screw T should be turned anti-  
clockwise until the cutting attachment stops.  
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.  
Fine adjustment of the idle speedT  
Adjust the idle speed using the idle adjustment screw T, if it is  
necessary to readjust. First turn the idle adjustment screw T  
clockwise until the cutting attachment starts to rotate. Then  
turn the screw anticlockwise until the cutting attachment  
stops. The idle speed is correctly adjusted when the engine

MAINTENANCE  
will run smoothly in every position.The idle speed should also  
be well below the speed at which the cutting attachment starts  
to rotate.  
Correctly adjusted carburetor  
When the carburetor is correctly adjusted the machine will  
accelerate without hesitation and burble a little at maximum  
speed. It is also important that the cutting attachment does  
not rotate at idle. 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.  
WARNING! If the idle speed cannot be  
adjusted so that the cutting attachment

mm Allen screw) to increase or decrease the start throttle  
speed.  
stops, contact your dealer/service  
workshop. Do not use the machine until it  
has been correctly adjusted or repaired.  
High speed jet H  
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.  
Proceed as follows:  
1
2
Run the machine at idle.  
Press the start throttle lock as described under the  
heading Starting and stopping.  
3
If the start throttle speed is too low (below 4000 rpm), turn  
the adjuster screw A clockwise until the cutting  
attachment starts to rotate. Then turn A clockwise a  
further 1/2 turn.  
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.  
4
If the start throttle speed is too high, turn the adjuster  
screw A anticlockwise until the cutting attachment stops.  
Then turn adjuster screw A clockwise a further 1/2 turn.  
Note that the engine should not be under load when you  
adjust the high speed jet H.You should therefore remove the  
cutting attachment, nut, support flange and drive disc before  
adjusting the high speed jet H.  
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 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.

CAUTION! For optimum adjustment of the carburettor,  
contact a qualified dealer/service workshop that has a  
revolution counter at their disposal.

MAINTENANCE  
Muffler  
Cooling system  
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.  
To keep the working temperature as low as possible the  
machine is equipped with a cooling system.  
4
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.  
3

The cooling system consists of:  
1
2
3
4
Air intake on the starter.  
Fins on the flywheel.  
Cooling fins on the cylinder.  
Cylinder cover (directs cold air over the cylinder).  
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.  
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.  
Bevel gear  
The bevel gear is filled with the right quantity of grease at the  
factory. However, before using the machine you should check  
that the bevel gear is filled three-quarters full with grease.Use  
HUSQVARNA special grease.  
CAUTION! Never use a machine with a defective muffler.  
The grease in the bevel gear does not normally need to be  
changed except if repairs are carried out.  
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

MAINTENANCE  
Air filter  
Spark plug  
The air filter must be regularly cleaned to remove dust and dirt  
in order to avoid:  
The spark plug condition is influenced by:  
Incorrect carburetor adjustment.  
Carburettor malfunctions  
Starting problems  
An incorrect fuel mixture (too much or incorrect type of  
oil).  
Loss of engine power  
A dirty air filter.  
Unnecessary wear to engine parts  
Excessive fuel consumption.  
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.  
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.  
CAUTION! Always use the recommended spark plug type!  
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.  
Use of the wrong spark plug can damage the piston/cylinder.  
Note:  
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.  
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.
