GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, re 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.
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 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 current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
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 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 and clothing 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.
■Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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.

Original Instructions
Power tools are dangerous in the hands of untrained
users.
■Maintain power tools and accessories. 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.
■Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
■Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with
another battery pack.
■Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
■When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause burns
or a fire.
■Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritation or burns.
■Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or
risk of injury.
■Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
■Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk of
fire.
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.
■Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
ROTARY TOOL SAFETY WARNINGS
Safety warnings common for grinding, sanding, wire
brushing, polishing, carving or abrasive cutting-off
operations
■This power tool is intended to function as a grinder,
sander, wire brush, polisher, carving or cut-off tool.
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury.
■Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can be
attached to your power tool, it does not assure safe
operation.
■The rated speed of the grinding accessories must be
at least equal to the maximum speed marked on the
power tool. Grinding accessories running faster than
their rated speed can break and fly apart.
■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 controlled.
■The arbour size of wheels, sanding drums or any
other accessory must properly fit the spindle or
collet of the power tool. Accessories that do not match
the mounting hardware of the power tool will run out
of balance, vibrate excessively and may cause loss of
control.
■Mandrel mounted wheels, sanding drums, cutters
or other accessories must be fully inserted into the
collet or chuck. If the mandrel is insufficiently held and/
or the overhang of the wheel is too long, the mounted
wheel may become loose and be ejected at high velocity.
■Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, sanding drum for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged
accessories 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 workshop apron capable of
stopping small abrasive or 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 of a broken accessory may fly away and
cause injury beyond immediate area of operation.
■Hold power tool by insulated gripping surfaces only,

4
Original Instructions
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.
■Always hold the tool firmly in your hand(s) during
the start-up. The reaction torque of the motor, as it
accelerates to full speed, can cause the tool to twist.
■Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other hand while in use. Clamping
a small workpiece allows you to use your hand(s) to
control the tool. Round material such as dowel rods,
pipes or tubing have a tendency to roll while being cut,
and may cause the bit to bind or jump toward you.
■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
accessory.
■Never lay the power tool down until the accessory
has come to a complete stop. The spinning accessory
may grab the surface and pull the power tool out of your
control.
■After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened. Loose
adjustment devices can unexpectedly shift, causing loss
of control, loose rotating components will be violently
thrown.
■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.
■Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, sanding band, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power tool
to be forced in the direction opposite of the accessory’s
rotation.
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. The operator can control kickback forces, if
proper precautions are taken.
■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 toothed saw blade. Such blades
create frequent kickback and loss of control.
■Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips
are thrown). Feeding the tool in the wrong direction
causes the cutting edge of the bit to climb out of the work
and pull the tool in the direction of this feed.
■When using rotary files, cut-off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually
breaks. When a rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from the groove and
you could lose control of the tool.
Safety warnings specic for grinding and abrasive
cutting-off operations
■Use only wheel types that are recommended for your
power tool and only for recommended applications.
For example: do not grind with the side of a cut-
off wheel. Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to these wheels
may cause them to shatter.
■For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and length.
Proper mandrels will reduce the possibility of breakage.
■Do not “jam” a cut-off 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 snagging of the
wheel in the cut and the possibility of kickback or wheel
breakage.
■Do not position your hand in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
■When wheel is pinched, snagged 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 cut-off 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 pinching or snagging.
■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

5
Original Instructions
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.
Safety warnings specic for wire brushing operations
■Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress
the wires by applying excessive load to the brush.
The wire bristles can easily penetrate light clothing and/
or skin.
■Allow brushes to run at operating speed for at least
one minute before using them. During this time no
one is to stand in front or in line with the brush.
Loose bristles or wires will be discharged during the run-
in time.
■Direct the discharge of the spinning wire brush
away from you. Small particles and tiny wire fragments
may be discharged at high velocity during the use of
these brushes and may become imbedded in your skin.
ADDITIONAL SAFETY WARNINGS
■Inspect for and remove all nails from the workpiece
before using the product. Following this rule will
reduce the risk of serious personal injury.
■Do not reach in the area of the spinning bit. The
proximity of the spinning bit to your hand may not always
be obvious.
■The product is not intended for use as a dental drill
or in human or veterinary medical applications.
Serious injury may result.
■Do not grind or sand heat flammable materials.
Sparks from the wheel could ignite these materials.
■Do not bend the flex shaft with a radius less than
13 mm. The risk of overheating will increase
substantially.
■Clamp workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
■Injuries may be caused, or aggravated, by prolonged
use of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
■Ambient temperature range for tool during operation is
between 0°C and 40°C.
■Ambient temperature range for tool storage is between
0°C and 40°C.
■The recommended ambient temperature range for the
charging system during charging is between 10°C and
38°C.
ADDITIONAL BATTERY SAFETY WARNINGS
■To reduce the risk of fire, personal injury, and product
damage due to a short circuit, never immerse your
tool, battery pack or charger in fluid or allow a fluid to
flow inside them. Corrosive or conductive fluids, such
as seawater, certain industrial chemicals, and bleach
or bleach-containing products, etc., can cause a short
circuit.
■Ambient temperature range for battery during use is
between 0°C and 40°C.
■Ambient temperature range for battery storage is
between 0°C and 20°C.

WARNING! The declared vibration total values and the
declared noise emission values given in this instruction manual
have been measured in accordance with a standardised test
and may be used to compare one tool with another. They may
be used for a preliminary assessment of exposure.
The declared vibration and noise emission values represent
the main applications of the tool. However, if the tool is used
for different applications, used with different accessories,
or poorly maintained, the vibration and noise emission
may differ. These conditions may signicantly increase the
exposure levels over the total working period.
An estimation of the level of exposure to vibration and noise
should take into account the times when the tool is turned off
or when it is running idle. These conditions may signicantly
reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator
from the effects of vibration and noise, such as maintaining
the tool and the accessories, keeping the hands warm (in case
of vibration), and organising work patterns.
