MACHINE´S SAFETY EQUIPMENT
General
This section describes the machine´s safety equipment, its
purpose, and how checks and maintenance should be carried
out to ensure that it operates correctly.
Throttle lockout
The throttle trigger lock is designed to prevent accidental
operation of the throttle. When the lock (A) is pressed in this
releases the throttle (B).
The trigger lock remains pressed in as long as the throttle is
pressed. When the grip on the handle is released the throttle
trigger and the throttle trigger lock both return to their original
positions. This is controlled by two independent return spring
systems. This means that the throttle trigger is automatically
locked in the idle position.
Checking the throttle lockout
• Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
• Press the throttle lockout and make sure it returns to its
original position when you release it.
• Check that the throttle trigger and throttle lockout move
freely and that the return springs work properly.
• Start the power cutter and apply full throttle. Release the
throttle control and check that the cutting blade stops and
remains stationary. If the cutting blade rotates when the
throttle is in the idle position you should check the
carburettor’s idle adjustment. See instructions in the
section "Maintenance".
Stop switch
Use the stop switch to switch off the engine.
Checking the stop switch
• Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Blade guard
This guard is fitted above the cutting blade and is designed to
prevent parts of the blade or cutting fragments from being
thrown towards the user.
Checking the blade guard
• Check that the guard over the cutting blade is not cracked
or damaged in any other way. Replace when damaged.
• Check that the cutting blade is fitted correctly and does
not show signs of damage. A damaged cutting blade can
cause personal injury.
!
WARNING! Never use a machine that has
faulty safety equipment! If your machine
fails any of these checks contact your
service agent to get it repaired.
The engine should be switched off, and the
stop switch in STOP position.
!
WARNING! Always check that the guard is
correctly fitted before starting the machine.

MACHINE´S SAFETY EQUIPMENT
Vibration damping system
• Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
• The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit. The engine
body, including the cutting equipment, is insulated from
the handles by vibration damping units.
Checking the vibration damping system
• Check the vibration damping units regularly for cracks or
deformation. Replace them if damaged.
• Check that the vibration damping element is securely
attached between the engine unit and handle unit.
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
Inspecting the muffler
Check regularly that the muffler is complete and secured
correctly.
!
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. These
symptoms may be increased in cold
temperatures.
!
WARNING! The engine should be switched
off, and the stop switch in STOP position.
!
WARNING! Never use a machine without a
muffler, or with a faulty muffler. A damaged
muffler may substantially increase the noise
level and the fire hazard. Keep fire fighting
equipment handy.
The 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.

CUTTING BLADES
General
• Cutting blades are available in two basic designs;
abrasive baldes and diamond blades.
• High-quality blades are often most economical. Lower
quality blades often have inferior cutting capacity and a
shorter service life, which results in a higher cost in
relation to the quantity of material that is cut.
• Make sure that the right bushing is used for the cutting
blade to be fitted on the machine. See the instructions
under the heading Assembling the cutting blade.
Suitable cutting blades
*Without water
**Diamond blades for dry cutting
Cutting blades for different materials
Follow the instructions supplied with the cutting blade
concerning the suitability of the blade for various applications,
or consult your dealer in case of doubts.
* Only specialty blades.
Hand-held, high-speed machines
• Our cutting blades are manufactured for high-speed,
portable power cutters.
• Check that the blade is approved for the same or higher
speed according to the aproval plate of the engine. Never
use a cutting blade with a lower speed rating than that of
the power cutter.
Blade vibration
• The blade can become out-of-round and vibrate if an
excessive feed pressure is used.
• A lower feed pressure can stop the vibration. Otherwise
replace the blade.
Abrasive blades
• The cutting material on abrasive blades consists of grit
bonded using an organic binder. ”Reinforced blades” are
made up of a fabric or fibre base that prevents total
breakage at maximum working speed if the blade should
be cracked or damaged.
• A cutting blade’s performance is determined by the type
and size of abrasive corn, and the type and hardness of
the bonding agent.
!
WARNING! A cutting blade may burst and
cause injury to the operator.

Cutting plastics with a diamond blade can
cause kickback when the material melts due
to the heat produced when cutting and
sticks to the blade. Never cut plastic
materials with a diamond blade!
Cutting in metal generates sparks that may
cause fire. Do not use the machine near to
ignitable substances or gases.

!
WARNING! Do not use abrasive blades with
water. The strength is impaired when
abrasive blades are exposed to water or
moisture, which results in an increased risk
of the blade breaking.
10 – English
CUTTING BLADES
• Ensure the blade it not cracked or damaged in any other
way.
• Test the abrasive blade by hanging it on your finger and
tapping it lightly with a screwdriver or the like. If the blade
does not produce a resonant, ringing sound it is damaged.
Abrasive blades for different materials
Rail cutting
Only use specially intended cutting blades for rail cutting.
Diamond blades
General
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
• Diamond blades ensure lower costs per cutting operation,
fewer blade changes and a constant cutting depth.
• When using diamond blades make sure that it rotates in
the direction indicated by the arrow on the blade.
Diamond blades for different materials
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
• Diamond blades are available in several hardness
classes.
• Special blades should be used when cutting metal. Ask
your dealer for help in choosing the right product.
Sharpening diamond blades
• Always use a sharp diamond blade.
• Diamond blades can become dull when the wrong feeding
pressure is used or when cutting certain materials such as
heavily reinforced concrete. Working with a blunt diamond
blade causes overheating, which can result in the
diamond segments coming loose.
• Sharpen the blade by cutting in a soft material such as
sandstone or brick.
Diamond blades for dry cutting
• Diamond blades for dry cutting can be used both with and
without water cooling.
• When dry cutting, lift the blade out from the cut every 30–
60 seconds and let it rotate in the air for 10 seconds to let
it cool. If this is not done, the blade may be overheated.
Diamond blades for wet cutting
• Diamond blades for wet cutting must be water cooled. If
this is not done, the blade may be overheated.
• Water cooling cools the blade and increases its service
life while also reducing the formation of dust.
Transport and storage
• Do not store or transport the power cutter with the cutting
blade fitted. All blades should be removed from the cutter
after use and stored carefully.
• Store cutting blades in dry, frost free conditions. Special
care should be taken with abrasive blades. Abrasive
blades must be stored on a flat, level surface. If an
abrasive blades is stored in humid conditions, this can
cause imbalance and result in injury.
• Inspect new blades for transport or storage damage.
Blade type Material
Concrete blade
Concrete, asphalt, stone masonry,
cast iron, aluminium, copper,
brass, cables, rubber, plastic, etc.
Metal blade
Steel, steel alloys and other hard
metals.
Blade for rail

!
WARNING! Cutting plastics with a diamond
blade can cause kickback when the material
melts due to the heat produced when cutting
and sticks to the blade.
Diamond blades get very hot when used. An
overheated blade is a result of improper use,
and may cause deformation of the blade,
resulting in damage and injuries.
Cutting in metal generates sparks that may
cause fire. Do not use the machine near to
ignitable substances or gases.

ASSEMBLING AND ADJUSTMENTS
General
Husqvarna’s blades are approved for hand-held power
cutters.
Checking the drive shaft and flange
washers
When the blade is replaced with a new one, check the flange
washers and the drive shaft.
• Check that the threads on the drive shaft are undamaged.
• Check that the contact surfaces on the blade and the
flange washers are undamaged, of the correct dimension,
clean, and that they run properly on the drive axle.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange washers.
Checking the bushing
Bushings are used to fit the machine to the centre hole in the
cutting blade. The machine is supplied with two different sized
bushings, 20 mm (25/32’’) and 25, 4 mm (1’’). A plate on the
blade guard indicates which bushing has been factory-fitted.
When replacing the bushing, the labeling of the machine must
be updated with the supplied decal.
• Check that the bushing on the machine's spindle shaft
corresponds with the centre hole of the cutting blade. The
blades are marked with the diameter of the centre hole.
Checking the direction of the blade
rotation
• When using diamond blades make sure that it rotates in
the direction indicated by the arrow on the blade. The
direction of rotation for the machine is shown by arrows on
the cutting arm.
Fitting the cutting blade
• The blade is placed on the bushing (A) between the inner
flange washer (B) and the flange washer (C). The flange
washer is turned so that it fits on the axle.
• Lock the shaft. Insert a tool in the hole in the cutting head
and rotate the blade until it is locked.
• Tightening torque for the bolt holding the blade is: 15-25
Nm (130-215 in.lb).
Blade guard
The guard for the cutting equipment should be adjusted so
that the rear section is flush with the work piece. Spatter and
sparks from the material being cut are then collected up by
the guard and led away from the user.
The blade guard is friction locked.
• Press the ends of the guard against the work piece or
adjust the guard with the adjustment handle. The guard
must always be fitted on the machine.
!
WARNING! The engine should be switched
off, and the stop switch in STOP position.
12 – English
ASSEMBLING AND ADJUSTMENTS
Reversible cutting head (K 1260)
The machine is fitted with a reversible cutting head allowing
cutting close to a wall or at ground level, restricted only by the
thickness of the blade guard.
There is an increased risk for kickback when cutting with the
cutting head reversed. The cutting blade is further away for
the centre of the machine which means the handle and the
cutting blade are no longer in alignment. It is more difficult to
restrain the machine if the blade gets jammed or stuck in its
kickback danger zone. See under the "Kickback" heading in
the "Operating" section for additional information.
Some of the machine's good ergonomic features may also be
jeopardised. Cutting with the cutting head reversed should
only occur with cuts that are not possible in a standard
manner.
• First release the two bolts and then the adjuster screw to
release the belt tension.
• Now unscrew the bolts and dismantle the belt guard.
• Disconnect the water hose from the blade guard.
• Remove the belt from the belt pulley.
• The cutting head is now loose and can be removed from
the machine.
• Remove the cutting head and attach it to the other side of
the cutting arm.
• Fit the belt guard to the reversed cutting head.
• Tighten the drive belt. See instructions in the section
"Maintenance".
• A longer water hose has to be fitted to the machine if wet
cutting is carried out.
English – 13
FUEL HANDLING
General
Fuel
Petrol
• Use good quality unleaded or leaded petrol.
• 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.
Environment fuel
The use of environmentl fuel (alkylate fuel), or environment
fuel for four-stroke engines blended with two-stroke oil as set
out below is recommended.
Ethanol blended fuel, E10 may be used (max 10% ethanol
blend). Using ethanol blends higher than E10 will create lean
running condition which can cause engine damage.
Two-stroke oil
• 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).
• Never use oil intended for four-stroke engines.
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.
• 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.
Mixing ratio
• 1:50 (2%) with HUSQVARNA two-stroke oil or equivalent.
• 1:33 (3%) with oils class JASO FB or ISO EGB formulated
for air-cooled, two-stroke engines.
Fueling
Never start the machine:
• If you have spilt fuel or engine oil on the machine. Wipe off
the spill and allow the remaining fuel to evaporate.
• 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.
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.
Long-term storage
• 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.
!
WARNING! Running an engine in a confined
or badly ventilated area can result in death
due to asphyxiation or carbon monoxide
poisoning. Use fans to ensure proper air
circulation when working in trenches or
ditches deeper than one meter.
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.
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!
Do not smoke and do not place any hot
objects in the vicinity of fuel.
NOTICE! 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.
Petrol, litre Two-stroke oil, litre
2% (1:50) 3% (1:33)
5 0,10 0,15
10 0,20 0,30
15 0,30 0,45
20 0,40 0,60
!
WARNING! Always stop the engine and let it
cool for a few minutes before refuelling. The
engine should be switched off, and the stop
switch in STOP position.
When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
Clean the area around the fuel cap.
Tighten the fuel cap carefully after refuelling.
Negligence may lead to the start of a fire.
Move the machine at least 3 m from the
refuelling point before starting it.

• Observe your surroundings to ensure that nothing can
affect your control of the machine.
• Ensure that no one/nothing can come into contact with the
cutting equipment or be hit by parts if the blade breaks.
• 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 can lead to dangerous
conditions, e.g. slippery surfaces.
• Never start to work with the power cutter before the
working area is clear and you have a firm foothold. Look
out for any obstacles with unexpected movement. Ensure
when cutting that no material can become loose and fall,
causing operating injury.Take great care when working on
sloping ground.
• Ensure that the working area is sufficiently illuminated to
create a safe working environment.
• Make sure that no pipes or electrical cables are routed in
the working area or in the material to be cut.
Basic working techniques
• Do not use the machine near to ignitable substances or
gases.
• The machine is designed and intended for cutting with
abrasive blades or diamond blades intended for high
speed handheld machines. The machine shall not be
used with any other type of blade, or for any other type of
cutting.
• Check that the cutting blade is fitted correctly and does
not show signs of damage. See the instructions in the
sections "Cutting blades" and "Assembly and settings".
• Check that the correct cutting blade is used for the
application in question. See instructions in the section
"Cutting blades".
• Never cut asbestos materials!
• Maintain a safe distance from the cutting blade when the
engine is running.
• Never leave the machine unsupervised with the motor
running.
• Never move the machine when the cutting equipment is
rotating.
• The guard for the cutting equipment should be adjusted so
that the rear section is flush with the work piece. Spatter
and sparks from the material being cut are then collected
up by the guard and led away from the user. The guards
for the cutting equipment must always be fitted when the
machine is running.
• Never use the kickback zone of the blade for cutting. See
instructions under the heading "Kickback".
• Keep a good balance and a firm foothold.
• Never cut above shoulder height. Never cut from a ladder.
Use a platform or scaffold when working at high altitude.
• Always hold the machine in a firm grip with both hands.
Hold it so that the thumbs and fingers grip round the
handles.
• Stand at a comfortable distance from the work piece.
• Check that the blade is not in contact with anything when
the machine is started
• Apply the cutting blade gently with high rotating speed (full
throttle) Maintain full speed until cutting is complete.
• Let the machine work without forcing or pressing the
blade.
!
WARNING! The safety distance for the power
cutter is 15 metres. You are responsible to
ensure that animals and onlookers are not
within the working area. Do not start cutting
until the working area is clear and you are
standing firmly.
!
WARNING! Do not pull the power cutter to
one side, this can cause the blade to jam or
break resulting in injury to people.
Under all circumstances avoid grinding
using the side of the blade; it will almost
certainly be damaged, break and can cause
immense damage. Only use the cutting
section.
Cutting plastics with a diamond blade can
cause kickback when the material melts due
to the heat produced when cutting and
sticks to the blade. Never cut plastic
materials with a diamond blade!
Cutting in metal generates sparks that may
cause fire.
16 – English
OPERATING
• Feed down the machine in line with the blade. Pressure
from the side can damage the blade and is very
dangerous.
• Move the blade slowly forwards and backwards to achieve
a small contact area between the blade and the material
to be cut. This reduces the temperature of the blade and
ensures effective cutting.
Managing dust (Applies only for K 1260)
The machine is fitted with DEX (Dust Extinguisher), a low
flushing water kit that offers maximum dust suppression.
Use wet cutting blades with DEX when possible for optimal
dust management. See instructions in the section "Cutting
blades".
Adjust water flow using the tap to bind the cutting dust. The
volume of water required varies depending on the type of job
at hand.
If water hoses loosen from their supply sources, this indicates
that the machine is connected to a water pressure that is too
high. See instructions under the "Technical data" heading for
recommended water pressure.
Rail cutting
General
Assembling the rail fixture
• Mount the rail fixture onto the rail. Screw the lock handle
tight.
• Mount the power cutter with its right side to the fixture.
The mounting on the power cutter is fitted closest to the
spindle on the cutting blade when assembling from this
side. Assembly should therefore be carried out primarily
from this direction.
Cutting guide
The cutting guide is used to facilitate guiding the blade to
where the cut is to be made. The first time you use the power
cutter, you must cut the guide.
• Fold out the cutting guide.
• Fix the cutting guide parallel to the rail in an appropriate
manner.
• Carefully cut off the guide.
Work procedure
• Fold out the cutting guide.
• Align the saw cut and fold in the guide.
NOTICE! The rail fixture must not be mounted on the
machine during transport or when handling the equipment.
The rail fixture is a precision tool that can be damaged if not
handled with care which results in less precise cuts.
NOTICE! The rail fixture must be first fitted to the rail before
the power cutter is fitted to the rail fixture. This is done to
guarantee that the fixture is attached at right angles to the
rail.
English – 17
OPERATING
• Begin the cutting process by swinging the machine back
and forth horizontally. This way the cutting blade’s contact
surface to the rail is minimised, which reduces the risk of
the blade glazing.
• When you have cut through the head (A), you continue
cutting the rib (B) and foot (C).
If the cut cannot be completed from one side, the power cutter
must be turned around.
• Shut off the machine.
• Dismantle the power cutter from the fixture.
• Fit the power cutter with its left side to the rail fixture.
• Guide the cutting blade down towards the rail and check
that the cutting blade is centred in the cut. If necessary,
adjust the movable bushing so that the blade ends up
centred in the middle of the cut.
• Now cutting can proceed.
General tips
• Only use specially intended cutting blades for rail cutting.
• Apply full throttle until the blade reaches top speed.
Reduce throttle to drop below the speed limitation which
reduces cutting blade vibrations when initiating a cut to
thereby produce straighter cuts. Apply full throttle and
maintain full speed until the cutting process is completed.
• Hold the machine’s handle so that the hands are in line
with the cutting blade. This to achieve maximum cutting
speed, blade service life and a straight cut.
• When performing the cutting process correctly, it takes
about one minute to cut a 50 kg/m-rail and about one and
a half minute to cut 60 kg/m-rail. If it takes longer, review
your cutting technique. Problems which arise are often the
result of incorrect cutting technique or poor cutting blades.
Kickback
Kickback is the sudden upward motion that can occur if the
blade is pinched or stalled in the kickback zone. Most
kickbacks are small and pose little danger. However a
kickback can also be very violent and throw the power cutter
up and back towards the user in a rotating motion causing
serious or even fatal injury.
Reactive force
A reactive force is always present when cutting. The force
pulls the machine in the opposite direction to the blade
rotation. Most of the time this force is insignificant. If the blade
is pinched or stalled the reactive force will be strong and you
might not be able to control the power cutter.
A
B
C
!
WARNING! Kickbacks are sudden and can
be very violent. The power cutter can be
thrown up and back towards the user in a
rotating motion causing serious or even fatal
injury. It is vital to understand what causes
kickback and how to avoid it before using
the machine.
18 – English
OPERATING
Kickback zone
Never use the kickback zone of the blade for cutting. If the
blade is pinched or stalled in the kickback zone, the reactive
force will push the power cutter up and back towards the user
in a rotating motion causing serious or even fatal injury.
Climbing kickback
If the kickback zone is used for cutting the reactive force
drives the blade to climb up in the cut. Do not use the
kickback zone. Use the lower quadrant of the blade to avoid
climbing kickback.
Pinching kickback
Pinching is when the cut closes and pinches the blade. If the
blade is pinched or stalled the reactive force will be strong and
you might not be able to control the power cutter.
If the blade is pinched or stalled in the kickback zone, the
reactive force will push the power cutter up and back towards
the user in a rotating motion causing serious or even fatal
injury.
Pipe cutting and pinching
Special care should be taken whet cutting in pipes. If the pipe
is not properly supported and the cut kept open through out
the cut the blade might be pinched in the kickback zone and
cause a severe kickback.
How to aviod kickback
Avoiding kickback is simple.
• The work piece must always be supported so that the cut
stays open when cutting through. When the cut opens
there is no kickback. If the cut closes and pinches the
blade ther is always a risk of kickback.
• Take care when inserting the blade in an existing cut.
• Be alert to movement of the work piece or anything else
that can occur, which could cause the cut to close and
pinch the blade.
Transport and storage
• Secure the equipment during transportation in order to
avoid transport damage and accidents.
• Do not store or transport the power cutter with the cutting
blade fitted.
• For transport and storage of cutting blades, see the
section "Cutting blades".
• For transport and storage of fuel, see the section "Fuel
handling".
• Store the equipment in a lockable area so that it is out of
reach of children and unauthorized persons.

MAINTENANCE
Cleaning
External cleaning
• Clean the machine daily by rinsing it with clean water after
the work is finished.
Cooling air intake
• Clean the cooling air intake when needed.
Spark plug
• If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking other steps.
• Ensure that the spark plug cap and ignition lead are
undamaged to avoid the risk of electric shock.
• If the spark plug is dirty, clean it and at the same time
check that the electrode gap is 0.5 mm. Replace if
necessary.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
• An incorrect fuel mixture (too much or incorrect type of
oil).
• A dirty air filter.
Functional inspection
General inspection
• Check that nuts and screws are tight.
Drive belt
Check the tension of the drive belt
• For correct tensioning of the drive belt, the square nut
should be positioned opposite the marking on the belt
cover.
Tensioning the drive belt
• The tension of a new drive belt must be readjusted after
one or two tanks of fuel have been used.
• The drive belt is enclosed and well protected from dust
and dirt.
• When the drive belt is to be tensioned, release the bolts
holding the cutting arm.
• Screw the adjuster screw so that the square headed nut
comes opposite the marking on the cover. This
automatically ensures that the belt has the correct
tension.
• Tighten both of the screws holding the cutting head using
a T-wrench.
NOTICE! A dirty or blocked air intake results in the machine
overheating which causes damage to the piston and
cylinder.
NOTICE! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/
cylinder.
English – 23
MAINTENANCE
Replacing the drive belt
• First release the two bolts and then the adjuster screw to
release the belt tension.
• Now unscrew the bolts and dismantle the belt guard.
• Remove the belt from the belt pulley.
• The cutting head is now loose and can be removed from
the machine.
• Remove the nut. Remove the side cover.
• Replace the drive belt.
• Assemble in the reverse order as set out for dismantling.
Carburettor
General
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.
The carburettor governs the engine speed via the throttle. Air
and fuel are mixed in the carburettor.
High speed jet
The carburetor is equipped with fixed H-jet to ensure the
engine always receives the correct fuel air mixture. If the
engine lacks power or accelerates poorly do the following:
• Check the air filter and replace if necessary. When this
does not help, contact an authorised service workshop.
Adjusting low speed jet
Apply full throttle a couple of times and check that the saw is
accelerating without hesitation. Basic setting L: 1 1/4 turn
open. If an adjustment is necessary, try to reach the
maximum idle speed, by slowly closing the low speed needle
L clockwise until the engine starves from fuel. Then open
(counter-clockwise) 1/8 of a turn. Check the engine
acceleration.
Adjusting the idle speed
Start the engine and check the idling setting. When the
carburettor is set correctly the cutting blade should be still
while engine is idling.
• Adjust the idle speed using the T screw. When an
adjustment is necessary, first turn the screw clockwise
until the blade starts to rotate. Now turn the screw anti-
clockwise until the blade stops rotating.
Rec. idle speed: 2700 rpm
!
WARNING! Never start the engine when the
belt pulley and clutch are removed for
maintenance. Do not start the machine
without the cutting arm or cutting head
fitted. Otherwise the clutch could come
loose and cause personal injuries.
NOTICE! A too lean adjusted low speed needle (the L-
needle closed too much) results in starting difficulties.
!
CAUTION! 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.

MAINTENANCE
Starter
Checking the starter cord
• Loosen the screws that hold the starter against the
crankcase and remove the starter.
• Pull the cord out about 30 cm and lift it into the cut-out in
the periphery of the starter pulley. When the cord is intact:
Release the spring tension by letting the pulley rotate
slowly backwards.
Changing a broken or worn starter cord
• Remove any remnants of the old starter cord and check
that the return spring works. Insert the new starter cord
through the hole in the starter housing and in the cord
pulley.
• Secure the starter cord around the cord pulley as
illustrated. Tighten the fastening well and ensure that the
free end is as short as possible. Secure the end of the
starter cord in the starter handle.
Tensioning the recoil spring
• Guide the cord through the cut-out in the periphery of the
pulley and wind the cord 3 times clockwise around the
centre of the starter pulley.
• Now pull the starter handle and in doing so tension the
spring. Repeat the procedure once more, but this time
with four turns.
• Note that the starter handle is drawn to its correct home
position after tensioning the spring.
• Check that the spring is not drawn to its end position by
pulling out the starter line fully. Slow the starter pulley with
your thumb and check that you can turn the pulley at least
a further half turn.
Changing a broken recoil spring
• Undo the bolt in the centre of the pulley and remove the
pulley.
• Carefully lift the cover that protects the spring. Bear in
mind that the return spring lies tensioned in the starter
housing.
• Carefully remove the spring using pilers.
• Lubricate the recoil spring with light oil. Fit the pulley and
tension the recoil spring.
!
WARNING! When the recoil spring is wound
up in the starter housing it is under tension
and can, if handled carelessly, pop out and
cause personal injury.
Always be careful when changing the recoil
spring or the starter cord. Always wear
protective goggles.
English – 25
MAINTENANCE
Fitting the starter
• To fit the starter, first pull out the starter cord and place the
starter in position against the crankcase. Then slowly
release the starter cord so that the pulley engages with
the pawls.
• Tighten the screws.
Fuel system
General
• Check that the fuel cap and its seal are not damaged.
• Check the fuel hose. Replace when damaged.
Fuel filter
• The fuel filter sits inside the fuel tank.
• The fuel tank must be protected from contamination when
filling. This reduces the risk of operating disturbances
caused by blockage of the fuel filter located inside the
tank.
• The filter cannot be cleaned but must be replaced with a
new filter when it is clogged. The filter should be
changed at least once per year.
Air filter
The air filter only needs to be checked if the engine drops in
power.
• Loosen the screws. Remove the air filter cover.
• Check the air filter and replace if necessary.
Replacing the air filter
• Loosen the screw.
• Replace the air filter.
Drive gear, clutch
• Check the clutch centre, drive gear and clutch spring for
wear.
NOTICE! The air filter must not be cleaned or blown clean
with compressed air. This will damage the filter.
