specially important parts of the manual.
WARNING: Used if there is a risk of injury or
death for the operator or bystanders if the
instructions in the manual are not obeyed.
CAUTION: Used if there is a risk of damage
to the product, other materials or the
adjacent area if the instructions in the

General power tool safety warnings
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.
Note: 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.
Electrical safety
•Power tool plugs must match the outlet. Never
modify the plug in any way. Unmodified plugs and
matching outlets will reduce 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, sharp 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 circuit interrupter (RCD)
protected supply. Use of a RCD reduces the risk of
electric shock
CAUTION: Do not pressure wash the
machine, as water can enter the electrical
system or the motor 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. Protective 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 a 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.
41461 - 001 - 17.02.2020

•Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
•If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
•The vibration emission during actual use of the
power tool can differ from the declared total value
depending on the ways in which the tool is used.
Operators should identify safety measures to protect
themselves that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it is
running idle in addition to the trigger).
•Remain at a distance from the blade when the motor
is running.
Power tool use and care
•Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it
was designed.
•Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
•Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
•Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained
users.
•Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool´s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
•Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
•Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
•Under no circumstances should you modify the
original design of the machine without approval from
the manufacturer. Always use original spare parts.
Unauthorized modifications and/or accessories may
lead to serious injury or death to the user or others.
•Make sure that no pipes or electrical cables are
routed in the working area or in the material to be
cut.
•Always check and mark out where gas pipes are
routed. Cutting close to gas pipes always entails
danger. Make sure that sparks are not caused when
cutting in view of the risk of explosion. Remain
concentrated and focused on the task. Carelessness
can result in serious personal injury or death.
Service
•Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is
maintained.
Cut-off machine safety warning
•The guard provided with the tool must be securely
attached to the power tool and positioned for
maximum safety so the least amount of wheel is
exposed towards the operator. Position yourself and
bystanders away from the plane of the rotating
wheel. The guard helps to protect operator from
broken wheel fragments and accidental contact with
the wheel.
•Use only bonded reinforced or diamond cut-off
wheels for your power tool. Just because an
accessory can be attached to your power tool, it
does not assure safe operation.
•The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated
speed can break and fly apart.
•Wheels must be used only for recommended
applications. For example, do not grind with the side
of the cut-off wheel.
•Always use undamaged wheel flanges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
•Do not use worn down reinforced wheels from larger
power tools. Wheels intended for a larger power tool
are not suitable for the higher speed of a smaller tool
and may burst.
•The outside diameter and the thickness of your
accessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
•The arbour size of wheels and flanges must properly
fit the spindle of the power tool. Wheels and flanges
with arbour holes that do not match the mounting
hardware of the power tool will run out of balance,
vibrate ecxessively and may cause loss of control.
•Do not use damaged wheels. Before each use,
inspect wheels for chips and cracks. If power tool or
wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the
wheel, position yourself and bystanders away from
the plane of the rotating wheel and run the power
1461 - 001 - 17.02.2020 5

tool at maximum no load speed for one minute.
Damaged wheels will normally break apart during
this test time.
•Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable of
stopping small workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or
respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
•Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or a broken wheel may fly away and
cause injury beyond immediate area of operation.
•Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
•Position the cord clear of the spinning accessory.If
you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the
spinning wheel.
•Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
your control.
•Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body.
•Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may
cause electrical hazards.
•Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
Kickback and related warnings
•Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel which in
turn causes the uncontrolled power tool to be forced
in the direction opposite of the wheel’s rotation at the
point of the binding.
•For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the
surface of the material causing the wheel to climb
out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of
the wheel’s movement at the point of pinching.
Abrasive wheels may also break under these
conditions.
•Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
•Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start-up. The operator can control torque
reactions or kickback forces, if proper precautions
are taken.
•Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
•Do not position your body in line with the rotating
wheel. Kickback will propel the tool in direction
opposite to the wheel’s movement at the point of
snagging.
•Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency
to snag the rotating accessory and cause loss of
control or kickback.
•Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
•Do not ”jam” the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the
cut and the possibility of kickback or wheel
breakage.
•When wheel is binding or when interrupting a cut for
any reason, switch off the power tool and hold the
power tool motionless until the wheel comes to a
complete stop. Never attempt to remove the wheel
from the cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
•Do not restart the cutting operation in the workpiece.
Let the wheel reach full speed and carefully re-enter
the cut. The wheel may bind, walk up or kickback if
the power tool is restarted in the workpiece.
•Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own
weight. Supports must be placed under the
workpiece near the line of cut and near the edge of
the workpiece on both sides of the wheel.
•Use extra caution when making a “pocket cut” into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.

Operation
Introduction
WARNING: Read and understand the safety
chapter before you use the product.
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 product.
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 product 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 product 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.
Rotational kickback
A rotational kickback occurs when the cutting blade
does not move freely in the kickback zone.
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
14 1461 - 001 - 17.02.2020

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. 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.
To cut in pipes
WARNING: If the blade is pinched in the
kickback zone it will cause a severe
kickback.
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. 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.
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.
1. Secure the pipe so it does not move or roll during
cutting.
2. Cut section "I" of the pipe.
I
III II
3. Ensure that the cut opens to avoid pinching.
4. Move to side II and cut from section I to bottom of
the pipe.
5. Move to side III and cut the remaining part of the
pipe ending at the bottom.
To prevent a kickback
WARNING: Avoid situations where there is a
risk of kickback. Take care when using your
power cutter and make sure that the blade is
never pinched in the kickback zone.
WARNING: Be careful when you put the
blade in an existing cut.
WARNING: Make sure that the work piece
cannot move during a cutting operation.
1461 - 001 - 17.02.2020 15

WARNING: Only you and proper working
technique can eliminate kickback and its
dangers.
• Always support the work of piece so that the cut can
keep open when cutting through. When the cut is
open there is no kickback. If the cut is closed and
pinches the blade, there is a risk of kickback.
To do before you start the product

Basic working techniques
WARNING: Do not pull the product to one
side. This can prevent the free movement of
the cutting blade. The cutting blade can
break and cause injury to the operator or
bystanders.
WARNING: Do not grind with the side of the
cutting blade. The cutting blade can break
and cause injury to the operator or
bystanders. Only use the cutting edge.
WARNING: Make sure that the cutting blade
is installed correctly and does not show
signs of damage.
WARNING: Before cutting in an existing cut
made by a different blade, make a sure that
the slot is not thinner than your blade as that
can result in binding in the cutting slot and a
kickback.
WARNING: Cutting metal generates sparks
that can cause fire. Do not use the product
near flammable material or gases.
• The product is made to cut with diamond blades
made for high speed handheld product. The product
must not be used with other types of blade, or for
other types of operation.
• Do a check that the correct cutting blade is used for
the material to be cut. Refer to
Cutting blades on
page 11
for instructions.
• Do not cut asbestos materials.
• Keep a safe distance from the cutting blade when
the motor is on. Do not try to stop a rotating blade
with a part of your body. To touch a rotating blade,
although the motor is off, can result in serious injury
or death.
• Make sure that only approved persons are in the
work area.
• The cutting blade continues to rotate for a while after
the power trigger is released. Make sure that the
cutting blade has stopped before the product is
moved or put down. If it is necessary to stop the
cutting blade quickly, let the cutting blade lightly
touch a hard surface.
• Do not move the product with the motor on.
• Hold the product with 2 hands. Hold the product
tightly with thumbs and fingers fully around the
plastic handles with insulation. The right hand must
be on the rear handle and the left hand on the front
handle. All operators must use this hold. Do not
operate a power cutter with only 1 hand.
• Make sure that you stay in a safe position and that
the cutting blade can move freely.
• Stand parallel to the cutting blade. Avoid standing
straight behind. If a kickback occur, the saw will
move in the plane of the cutting blade.
• Do not go away from the product with the motor on.
Before you go away from the product, stop the motor
16 1461 - 001 - 17.02.2020

and make sure that there is no risk of accidental
start.
• Use the adjustment handle of the blade guard to
adjust the rear section of the guard flush with the
work piece. Spatter and sparks from the cut material
are then collected up by the guard and led away
from the operator. The guards for the cutting
equipment must always be installed when the
product is on.
• Do not use the kickback zone of the blade for
cutting. Refer to Kickback zone on page 14 for
instructions.
• Do not operate the product before the work area is
clear and your feet and body are in a stable position.
• Do not cut above shoulder height.
• Do not cut from a ladder. Use a platform or scaffold if
the cut is above shoulder height. Do not overreach.
• Stay at a comfortable distance from the work piece.
• Make sure that the cutting blade can move freely
when the motor is started.
• Apply the cutting blade carefully with high rotating
speed (full power). Keep full speed until cutting is
complete.
• Let the product do the work. Do not push the cutting
blade.
• Feed the product down in line with the blade.
Pressure from the side can cause damage to the
blade and is very dangerous.
• Move the blade slowly forward and rearward to get a
small contact area between the blade and the
material to be cut. This decreases the temperature of
the blade and is an effective way to cut.

To make a straight cut
1. Attach a long straight object as a support along the
line where the cut is to be made.
2. For the best result, cut first with a power cutter with a
Husqvarna special pre-cut blade.
WARNING: Do not use a power cutter
with a standard cutting blade for this first
cut. A standard cutting blade makes a
slot cut that is too thin. When you then
cut with the ring cutting blade, the too
thin slot causes dangerous kickback and
pinching of the ring cutting blade.
3. Cut the full length of the cut to a depth of 2-3 cm/
0.79-1.18 in. Keep the cutting blade against the
support to make the cut straight.
4. Lift the cutting blade from the cut.

5. Go back to the start of the cut and cut 2-3 cm/
0.79-1.18 in. again, until the full length of the cut has
a depth of 5-10 cm/1.97-3.94 in.
6. Continue to cut to necessary depth.
To cut holes
WARNING: Make sure that large cut pieces
cannot fall on the operator or the product
when you cut.
CAUTION: Cut pieces can fall and cause
damage to the product if the cuts are made
in the incorrect sequence. Always make the
