CUTTING BLADES
General
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.
· 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
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.
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.
· This machine is only to be used with Husqvarna´s specially developed diamond
blades intended for Cutn-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
WARNING! Never use a cutting blade for
!
any other materials than what it was
intended to cut.
· 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 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
dull 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.
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.

Assembly
ASSEMBLY
WARNING! Always pull out the plug from
!
the outlet socket before cleaning,
maintenance or assembly.
Assembling the blades
!
WARNING! You must replace the screw kit when you replace the blade.
· Husqvarna blades are especially manufactured and approved for freehand
cutting with the K 4000 Cutn-Break. The blades have integrated belt pulley
halves and are to be changed in pairs.
· Loosen the nuts and clamping bolt which release the bar. 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.
NOTICE! Do not forget to tighten the belt and check the belt adjustment before cutting. See the instructions under the heading “Inspecting and adjusting the drive belt”.
· Dismantle the old blades by loosening the centre nut. Check the drive belt
for wear when the blades are dismantled. When changing the drive belt see the
instructions under the heading “Replacing the drive belt”.
NOTICE! It is very important that the blades rotate when the nut is tightened.
This is to ensure that the belt is not clamped between the integrated drive
belt halves on the blades when the blades/drive belt are pulled together with
the nut. Ideally this is done alternately, i.e. tighten a little, rotate a
little and repeat until the blades are secured.
· Place the blades on each side of the bar. Insert the steering pins of the
nut through the blades and the bolt washer.
· Rotate the blades by hand while tightening the blade bolt. This is
especially important because it assures the belt is not squeezed between the
pulley halves, which are incorporated into the blades. Alternate between
tightening the blade bolt and rotating the blades until the blades are fully
tightened. Tighteningtorque for the bolt holding the blade is: 130 in.lb (15
Nm).
Protection for the blades
· The guards should always be fitted on the machine. Check that the guards are
properly secured and work before starting to cut.

General safety warnings
This section describes basic safety directions for using the machine. This
information is never a substitute for professional skills and experience. If
you get into a situation where you feel unsafe, stop and seek expert advice.
Contact your dealer, service agent or an experienced user. Do not attempt any
task that you feel unsure of!
· Please read the operator’s manual carefully and make sure you understand the
instructions before using the machine. It is recommended that first time
operators also obtain practical instruction before using the machine.
· Keep in mind that it is you, the operator that is responsible for not
exposing people or their property to accidents or hazards.
· The machine must be kept clean. Signs and stickers must be fully legible.
WARNING! Read all safety warnings and
!
all instructions. Failure to follow the
warnings and instructions may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
Work area safety
· Keep work area clean and well lit. Cluttered or dark areas invite accidents.
· Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools create sparks which may
ignite the dust or fumes.
· Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
· Do not use the machine in bad weather, such as dense fog, 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 machine before the working area is clear and
you have a firm foothold. Look out for any obstacles with unexpected
English – 11
OPERATING
movement. Ensure when cutting that no material can become loose and fall, causing injury to the operator.Take great care when working on sloping ground.
WARNING! The safety distance for the
!
power cutter is 50 feet (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.
Electrical safety
· Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce the risk of electric shock.
· Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
· Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
· Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, charp edges or
moving parts. Damaged or entangled cords increase the risk of electric shock.
· When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
· If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected device. Use of an RCD reduces the risk of
electric shock.
· Check that the cord and extension cord are intact and in good condition.
Never use the machine if the cord is damaged, hand it in to an authorized
service workshop for repair. An undersized cable means a risk of reduced
machine capacity and overheating.
· The machine should be connected to an earthed outlet socket. Check that the
mains voltage corresponds with that stated on the rating plate on the machine.
· Ensure the cord is behind you when you start to use the machine so that the
cord will not be damaged.
WARNING! Do not pressure wash the
!
machine, as water can enter the
electrical system or the engine and
cause damage to the machine or short
circuit.
Personal safety
· Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power
tools may result in serious personal injury.
· Use personal protective equipment. Always wear eye protection. Protetctive
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.
· Prevent unintentional starting. Ensure the switch is in the OFF-position
before connecting to power source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the switch or energising
power tools that have the switch on invites accidents.
· Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
· Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
· Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or long

damage in people who have impaired
circulation. Contact your doctor if you
experience symptoms of overexposure
to vibration. These 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.
Power tool use and care
· Please read the operator’s manual carefully and make sure you understand the
instructions before using the machine.
12 – English
OPERATING
· The machine is only designed for cutting hard materials, such as concrete, brick, masonry as well as cast iron and cement pipes.

Basic working techniques
WARNING! This section describes basic
!
safety directions for using a power
cutter. This information is never a
substitute for professional skills and
experience. If you get into a situation
where you feel unsafe, stop and seek
expert advice. Contact your dealer,
service agent or an experienced power
cutter user. Do not attempt any task that
you feel unsure of!
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!
· Always hold the machine in a firm grip with both hands. Hold it so that the
thumbs and fingers grip round the handles.
· Check that the blade is not in contact with anything when the machine is
started
· Start cutting with the machine running at maximum speed.
· Start cutting smoothly, allowing the machine to work without forcing or
pressing in the blade. Always cut at maximum speed.
· Cut in the same direction when cutting into an existing cut. Avoid cutting
at an angle to the previous cut, otherwise there is a risk of the blade
jamming or that the machine can “climb in the cut” and cause a kickback.
Cutting metal generates sparks that may cause fire. Do not use the machine
near ignitable substances or gases.
Water cooling
Water cooling must always be used. Dry cutting causes immediate overheating
and machine and cutting blade failure with a risk of personal injury.
· Always cut from top to bottom (A).
· Remove the cutter and use a crowbar to remove the material that remains
between the cut (B).
At a low water pressure, for example when the water tank is used, the
restrictor can be dismantled to give the correct water flow.
NOTICE! It is important not to use a too high water flow without throttling as
the belt can then slip.
Cutting technique
· Support the work piece in such a way that it is possible to predict what
will happen, and so that the cut remains open while cutting.
14 – English
OPERATING
· Follow the same saw cut, but further in the work piece (C), and repeat the work with the crowbar.
Smooth cutting
To enable smooth cutting, the splash guard must be adjusted.
· Release the latch.
WARNING! When cutting vertically,
!
always cut from the top of the cut and
down. Never cut from the bottom of the
cut and up. This can cause a kickback
and result in personal injury.
· Repeat this working method until the required cutting depth is achieved (D, E).
· Slide the splash guard sideways.
· The blade guards are designed to easily adapt to how deep in the work piece the power cutter is moved.
· Lock the latch.
Kickback
Kickback is a sudden, rearward motion of the saw that can occur if the blades
are stalled (pinched, jammed, twisted) in the so called kickback zone. Most
kickbacks are small and felt as small “jerks” in the front handle. However,
kickback can be very powerful. If you are not paying attention or have a poor
grip the saw can be thrown all the way back at you.
WARNING! Kickback can be very sudden
!
and viloent, throwing the saw back at
you. It can cause serious or even fatal
injuries. It is vital you understand what
causes kickback and how to aviod it
using proper cutting techique.
WARNING! Under all circumstances
!
avoid grinding using the side of the
blade; it will almost certainly be
damaged or break and can cause
immense damage. Only use the cutting
section.
Do not pull the power cutter to one side, this can cause the blade to jam or break resulting in injury to people.
English – 15
OPERATING
Cause of kickback Kickback is caused if you are cutting with the kickback zone
of the blade for example when cutting “upwards” or towards you.
General rules · Never cut upwards or towards you so that the kickback
zone becomes actively cutting.
· Keep a good balance and a firm foothold.
· When cutting vertically, always cut from the top of the cut and down.
· Always cut at maximum speed.
· Do not cut with the upper quadrant (kickback zone) of the blade. Avoid
twisting or pushing the blades sideways in the cut. This can cause kickback.
· Take care when inserting the blade in an existing cut. Make certain that the
cut is wide enough and that the blades are not angled in the cut. This can
cause kickback.
· Stand at a comfortable distance from the work piece.
· Never cut above shoulder height.
· Never cut from a ladder. Use a platform or scaffold if the cut is above
shoulder height.
· Always hold the machine in a firm grip with both hands. Hold it so that the thumbs and fingers grip round the handles.
· 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.
Pull in
Pull in occurs when the blades’ lower sections suddenly stop or when the cut
closes. (To avoid, see the instructions under the heading “General rules” and
“Pinching/rotation”, here below.).
Pinching/rotation
If the cut is pressed together this can lead to jamming. The machine can be
pulled down suddenly with a very powerful jerk.
How to avoid pinching
Support the work piece in such a way that the cut remains open during the
cutting operation and when the cut is finished.
16 – English
Check the engine speed
Use a revolution counter regularly to check the engine speed at the working
temperature, at full throttle and without a load.

MAINTENANCE
WARNING! The user must only carry out the maintenance and service work described in this
!
manual. More extensive work must be carried out by an authorized service workshop.
Inspection and/or maintenance should be carried out with the motor switched off and the plug disconnected. Wear personal protective equipment. See instructions under the heading “Personal protective equipment”. The life span or the runtime 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 service workshop.

washer when rinsing the inside of the
machine.
The machine can withstand taking in damp air and splashes during the cutting
process. Clean water does not affect the machine’s function.
When cutting materials such as concrete or brick, which can contain salt, you
must rinse the machine after the work is finished. The cleaning reduces the
risk for accretions building up inside the engine, which can cause leakage
current between electric components, which in turn can cause the ground fault
circuit interrupter to turn off without intention.
· Clean the machine daily by rinsing it with clean water after the work is
finished.
· Place the machine with the rear handle facing upwards. Rinse the air intakes
at the rear handle with clean water. The water will run out through the front
air outlets.
· Connect the plug and run the engine dry for approx. 30 sec in order to speed
up the drying of the engine.
Cooling system
· The machine is equipped with an efficient fan to cool the motor. Cooling air
which is drawn in through the grille by the machines rear handle passes over
the stator and rotor and out through the front of the motor housing.
