MA CHINE´S SAFETY EQ UIPMENT
6 – English
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.
!
WARNING! Never use a machine that has
faulty safety equipment! If your machine
fails any checks contact your service
agent to get it repaired.
The engine should be switched off, and
the stop switch in STOP position.

MACHINE´S SAFETY EQUIPMENT
English – 7
Blade guards/Spray guard
These guards are fitted above and below the blades and
are designed to prevent parts of the blades or cut material
from being thrown towards the user and minimize the risk
of operator contact with the cutting blade.
Check the blade guards/spray guard
• Check that the guards are not damaged or broken.
Replace when damaged.
• Also check that the blades are fitted correctly and are
not damaged in anyway. Damaged blades can cause
personal injuries. See instructions in the section
"Cutting blades" and "Maintenance".
Vibration damping system
• Your machine is equipped with a vibration damping
system that is designed to reduce 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! Always check that the blade
guards are correctly fitted before starting
the machine.
!
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 as well as when idling. Be
aware of the fire hazard, especially when
working near flammable substances and/
or vapors.
Keep fire fighting equipment handy.

CUTTING BLADES
8 – English
General
• This machine is only to be used with Husqvarna´s
specially developed diamond blades intended for Cut-
n-Break. The blades have an integrated belt pulley
and are approved for freehand cutting.
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
• Always use a sharp diamond blade.
• Ensure the blades are not cracked or damaged in any
other way. Replace blades if necessary.
Diamond blades for different materials
•Diamond blades are ideal for masonry and reinforced
concrete. Ask your dealer for help in choosing the
right product.
• Diamond blades are available in several hardness
classes. A "soft" diamond blade has a relatively short
service life and large cutting capacity. It is used for
hard materials such as granite and hard concrete. A
"hard" diamond blade has a longer service life and
reduced cutting capacity, and should be used for soft
materials such as brick and asphalt.
Water cooling
• Water cooling must always be used.
• Using wet cutting blades without water can cause
excessive heat build-up, resulting in poor performance,
severe blade damage and is a safety hazard.
• Water cooling cools the blade and increases its
service life while also reducing the formation of dust.
Sharpening diamond blades
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 blades by cutting a soft material such as
sandstone or brick.
Transport and storage
•Make sure the machine is secured and that the cutting
blades are properly protected during the transport and
storage of the machine.
• Before use inspect all blades for transport or storage
damage.
!
WARNING! A cutting blade may burst
and cause injury to the operator.
A cutting blade should be checked
before it is assembled on the saw and
frequently during use. Look for cracks,
lost segments (diamond blades) or
pieces broken off. Do not use a damaged
cutting blade.
Test the integrity of each new cutting
blade by running it at full throttle for
about 1 minute.
Only use original cutting blades
designed by Husqvarna for use on this
machine.
Husqvarna issues warnings and
recommendations for the use and proper
care of the cutting blades. Those
warnings come with the cutting blades.
Read and follow all instructions from
Husqvarna.
!
WARNING! Never use a cutting blade for
any other materials than what it was
intended to cut.
Never use a diamond blade to cut plastic
material. The heat produced during
cutting may melt the plastic and it can
stick to the cutting blade and cause a
kickback.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
!
WARNING! Cool diamond blades
designed for wet cutting continuously
with water to prevent heating, which can
deform the diamond blade resulting in
damage to the machine and personal
injury.

FUEL HANDLING
English – 9
General
Fuel
Gasoline
• Use good quality unleaded gasoline.
• The lowest recommended octane grade is 87
((RON+MON)/2). If you run the engine on a lower
octane grade than 87 so-called knocking can occur.
This gives rise to a high engine temperature and
increased bearing load, which can result in serious
engine damage.
• When 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 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.
• 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 or mix
as per recommendation from the oil manufacturer.
!
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 (3 foot).
Fuel and fuel fumes are flammable 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
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.

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 gas station
to find out where to dispose of excess fuel.
!
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. If the cap is not properly
tightened the cap might vibrate lose and

• Push the cutting blades straight in and down once
desired depth has been reach.
• Do not cut upwards or push the cutting blades
upwards as the reactive forces will try to push the saw
back at you and in worst case scenario the saw can be
pushed back far enough to a kcikback to develop.
Managing dust
The machine is fitted with DEX (Dust Extinguisher), a low
flushing water kit that offers maximum dust suppression.
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.
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.
Never move the machine when the cutting equipment is
rotating. Gyroscopic forces can obstruct the intended
movement.
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.
!
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.

OPERATING
English – 15
•Never cut upwards or towards you so that the kickback
zone becomes actively cutting.
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. Be alert for potential movement of the
work piece. If the work piece is not properly supported
and shifts as you cut, it might pinch the blade and cause
a kick back.
Pipe cutting
Special care should be taken when cutting in pipes. If the
pipe is not properly supported and the cut kept open
through out the cutting, the blade might be pinched in the
kickback zone and cause a severe kickback. Be
especially alert when cutting a pipe with a belled end or a
pipe in a trench that, if not properly supported, may sag
and pinch the blade.
Before starting the cut the pipe must be secure so it does
not move or roll during cutting.
If the pipe is allowed to sag and close the cut, the blade
will be pinched in the kick back zone and a severe kick
back might develop. If the pipe is properly supported the
end of the pipe will move downward, the cut will open and
no pinching will occur.
Proper sequence cutting a pipe
1 First cut section I.
2 Move to side II and cut from section I to bottom of the
pipe.
3 Move to side III and cut the remaining part of the pipe
ending at the bottom.
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 there 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.
• 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.

Before starting
• Perform daily maintenance. See instructions in the
section "Maintenance".
Starting
With a cold engine:
• Make sure that the stop switch (STOP) is in the left
position.
• Start throttle position and choke is obtained by pulling
out the choke control completely.
•Decompression valve: Press in the valve to reduce
the pressure in the cylinder, this is to assist starting
the power cutter. The decompression valve should
always be used when starting. The valve
automatically returns to its initial position when the
machine starts.
• Press the air purge diaphragm repeatedly until fuel
begins to fill the diaphragm (about 6 times). The
diaphragm need not be completely filled.
• Grip the front handle with your left hand. Put your right
foot on the lower section of the rear handle pressing
the machine against the ground. Pull the starter
handle with your right hand until the engine starts.
Never wrap the starter cord around your hand
!
WARNING! Note the following before
starting: Please read the operator’s
manual carefully and make sure you
understand the instructions before using
the machine.
Wear personal protective equipment. See
under heading ”Personal protective
equipment”.
Do not start the machine without the belt
and belt guard fitted. Otherwise the
clutch could come loose and cause
personal injuries.
Check that the fuel cap is properly
secured, and that there is no fuel
leakage.
Make sure no unauthorised persons are

• Press the throttle trigger to disengage the start throttle
and the machine will idle.
With a warm engine:
• Make sure that the stop switch (STOP) is in the left
position.
• Set the choke control in the choke position. The choke
position is also the automatic start throttle position.
•Decompression valve: Press in the valve to reduce
the pressure in the cylinder, this is to assist starting
the power cutter. The decompression valve should
always be used when starting. The valve
automatically returns to its initial position when the
machine starts.
• Push the choke control to disable the choke (the start
throttle position remains).
• Grip the front handle with your left hand. Put your right
foot on the lower section of the rear handle pressing
the machine against the ground. Pull the starter
handle with your right hand until the engine starts.
Never wrap the starter cord around your hand
•Press the throttle trigger to disengage the start throttle
and the machine will idle.
NOTICE! Pull with your right hand out the starter cord

!
WARNING! When the engine is running
the exhaust contains chemicals such as
unburned hydrocarbons and carbon
monoxide. The content of the exhaust
fumes is known to cause respiratory
problems, cancer birth defects or other
reproductive harm.
Carbon monoxide is colorless and
tasteless and is always present in
exhaust fumes. The onset of carbon
monoxide poisoning is distinguished by
a slight dizziness which may or may not
be recognized by the victim. A person
may collapse and lapse into
unconsciousness with no warning if the
concentration of carbon monoxide is
sufficiently high. Since carbon monoxide
is colorless and odorless, its presence
can not be detected. Any time exhaust
odors are noticed, carbon monoxide is
present. Never use a gasoline powered
power cutter indoors or in trenches more
than 3 feet (1 meter) deep or in other
areas with poor ventilation. Ensure
proper ventilation when working in
trenches or other confined areas.

STARTING AND STOPPING
18 – English
Stopping
•Stop the engine by moving the stop switch (STOP) to
the right.
!
CAUTION! The cutting blade continues to
rotate up to a minute after the motor has
stopped. (Blade coasting.) Make sure
that the cutting blade can rotate freely
until it is completely stopped.
Carelessness can result in serious
personal injury.

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.
Cutting blades
Replacing the blades
The blades have integrated belt pulley halves and are to
be changed in pairs.
• Loosen the bar nuts one turn anticlockwise.
• Screw the belt adjuster a few turns anticlockwise.
• This will position the drive belt in a more favourable
position with regard to assembling the new blades.
The drive belt is not clamped so easily.
• Dismantle the old blades by loosening the centre nut.
• Check the drive belt for wear. See instructions under
the heading "Drive belt".
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.
!
CAUTION! You must replace the screw
kit when you replace the blade.
•Place the blades on each side of the bar. Insert the
steering pins of the nut through the blades and the
bolt washer.
