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 Charles 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. Husqvarna

GENERAL SAFETY PRECAUTIONS
Cutting attachment guard
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.
Check that the guard is undamaged and not cracked. Replace
the guard if it has been exposed to impact or is cracked.
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 vibration damping element is undamaged and
securely attached.
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.
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.
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
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 machine′s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine
Regularly check the vibration damping units for cracks or
deformation.
′s handle unit.
Check that the harness straps are correctly positioned. Once
the harness and machine have been adjusted, check that the
harness quick release works correctly.
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user. A muffler
fitted with a catalytic converter is also designed to reduce
harmful exhaust gases.
In countries that have a warm and dry climate there is a
significant 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.
English – 9
GENERAL SAFETY PRECAUTIONS
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to the
machine.
If the muffler on your machine is fitted with a spark arrestor
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!
Locking nut
A locking nut is used to secure some types of cutting
attachment.
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.
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.
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!
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
Reduce the risk of blade thrust.
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.
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.
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
!
blade increases the risk of kickback.
10 – English
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.
GENERAL SAFETY PRECAUTIONS
Sharpening grass cutters and grass
blades
•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.
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.
Trimmer head
•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.
•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.
•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.
IMPORTANT! Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the machine
will generate harmful vibration.

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 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.
•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
CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of petrol
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.
Petrol
CAUTION! Always use a quality petrol/oil mixture at least 90
octane (RON). If your machine is equipped with a catalytic
converter (see chapter on Technical data) always use a good
quality unleaded petrol/oil mixture. Leaded petrol will destroy
the catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if it is
available.
•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 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.
•A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of catalytic
converters.
•Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.
1:33 (3%) with oils class JASO FB or ISO EGB formulated
for air-cooled, two-stroke engines.

•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.
•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.
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.
Fuelling
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.
English – 17
STARTING AND STOPPING
Check before starting
•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.
•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.
•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.
Starting and stopping
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.
Starting
Ignition: Set the stop switch to the start position.
•Check that the blade guard is not damaged or cracked.
Replace the blade guard if it is exposed to impact or is
cracked.
•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.
Primer bulb: Press the air purge repeatedly until fuel begins
to fill the bulb. The bulb need not be completely filled.
Choke: Set the choke control in the choke position.
-
-
•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.
18 – English
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.
STARTING AND STOPPING
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 twist 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.
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.
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.
Stopping
Stop the engine by switching off the ignition.

WORKING TECHNIQUES
General working instructions
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.
Basic safety rules
1 Look around you:
•To ensure that people, animals or other things cannot
affect your control of the machine.
•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.
•CAUTION! Do not use the machine unless you are able to
call for help in the event of an accident.
2 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.
3 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.
7 Switch off the engine before moving to another area. Fit
the transport guard before carrying or transporting the
equipment any distance.
8 Never put the machine down with the engine running
unless you have it in clear sight.
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.
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.
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.
Basic working techniques
Always slow the engine to idle speed after each working
operation. Long periods at full throttle without any load on the
engine can lead to serious engine damage.
4 Keep a good balance and a firm foothold.
5 Always hold the machine with both hands. Hold the
machine on the right side of your body.
6 Keep the cutting attachment below waist level.
20 – English
WARNING! Sometimes branches or grass
get caught between the guard and cutting
!
attachment. Always stop the engine before
cleaning.
WARNING! 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 kickback can occur if you
attempt to cut thick stems with this area of
the blade.
WORKING TECHNIQUES
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 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.
•Let the support cup rest lightly against the ground. It is
used to protect the blade from hitting the ground.
•Reduce the risk of material wrapping around the blade by
following these instructions:
1 Always work at full throttle.
2 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.
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.
Grass trimming with a trimmer head
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.
•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.
Sweeping
•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.
•When cutting and sweeping you should use full throttle to
obtain the best results.

MAINTENANCE
Carburettor
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.
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 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.
Adjusting the idle speed (T)
Check that the air filter is clean. When the idle speed is
correct, the cutting attachment should not rotate. If
adjustment is required, close (turn clockwise) the idle
adjustment screw T, with the engine running, until the cutting
attachment starts to rotate. Open (turn anticlockwise) the
screw until the cutting attachment stops. The idle speed is
correctly set when the engine runs smoothly in all positions,
and there is a clear margin to the speed at which the cutting
attachment starts to rotate.
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.
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.
CAUTION! Never use a machine with a defective muffler.
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!
+
+
--
Note: The machine should only be run for short periods at its
highest speed.
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.
22 – English
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
4
1
2
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.
3
MAINTENANCE
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.
142R/143R
132R/
133R
142R/
143R
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
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.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
Spark plug
The spark plug condition is influenced by:
•Incorrect carburettor 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 0,6-0,7 mm. The spark plug should
be replaced after about a month in operation or earlier if
necessary.
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.
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.
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.
