General Safety Directions for
Power Tools
WARNING! READ ALL SAFETY
DIRECTIONS AND INSTRUC-
TIONS. Omissions in the compliance
with safety directions and instructions
can cause electrical shock, re and/
or severe injuries.
Retain all safety directions and in-
structions for future use.
The term „power tool“ in the warnings refers
to your mains-operated (corded) power tool
or battery-operated (cordless) power tool).
1) Work area safety :
a) Keep work area clean and well
lit. Cluttered or dark areas invite acci-
dents.
b) Do not operate power tools in
explosive atmospheres, such as
in the presence of ammable
Iiquids, gases or dust. Power tools
create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders
away while operating a power
tool. Distractions can cause you to lose
control.
2) Electrical safety :
CAUTION! The following states how
to avoid accidents and injuries due to
electric shock:
a) 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. Unmodied plugs and
matching outlets will reduce risk of electric
shock
b) Avoid body contact with earthed
or grounded surfaces, such as
pipes, radiators, ranges and re-
frigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain
or wet conditions. Water entering a
power tool will increase the risk of electric
shock.
d) 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 elec-
tric shock.
e) When operating a power tool out-
doors, use an extension cord suit-
able for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of

9
GB IE
electric shock.
f) 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. Use a
circuit breaker with a current limit of
30 mA or less.
3) Personal safety:
CAUTION! The following states how
to avoid accidents and injuries:
a) 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 inuence of
drugs, alcohol or medication. A mo-
ment of inattention white operating power
tools may result in serious personal injury.
b) Use personal protective equip-
ment. Always wear eye protec-
tion. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting.
Ensure the switch is in the off-po-
sition before connecting to power
source and/or battery pack, pick-
ing up or carrying the tool. Carry-
ing power tools with your nger on the
switch or energising power tools that have
the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the power
tool in unexpected situations.
f) 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.
g) 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.
4) Power tool use and care :
a) 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.
b) 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.
c) Disconnect the plug from the
power source and/or the battery
pack from the power tool before
making any adjust -ments, chang-
ing accessories, or storing power
tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentaIly.
d) Store idle power tools out of the
reach of children and do not al-
low persons unfamiliar with the
power tool or these instructions to
operate the power tool. Power tools
are dangerous in the hands of untrained
users.
e) Maintain power tools. Check for
misalignment or binding of mov-
ing parts, breakage of parts and
any other condition that may af-

10
GB IE
fect the power tool’s operation.
If damaged, have the power tool
repaired before use. Many accidents
are caused by poorly maintained power
tools.
f) Keep cutting tools sharp and
clean. Properly maintained cutting tools
with sharp cutting edges are less Iikely to
bind and are easier to control.
g) 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 dif-
ferent from those intended could result in
a hazardous situation.
5) CAREFUL HANDLING AND USE OF
BATTERYDEVICES
a) Charge the batteries only in charg-
ers that are recommended by the
manufacturer. Risk of re if a charger
that is suitable for a specic type of bat-
tery is used with other batteries.
b) In the power tools, use only the
batteries designed for the pur-
pose. The use of other batteries may
result in injuries and risk of re.
c) Keep the unused battery away
from paper clips, coins, keys,
nails, screws and other small
metal objects, which could cause
bridging of the contacts. A short
circuit between the battery contacts may
cause burns or re.
d) If used incorrectly, liquid may leak
from the battery. Avoid contact
with this. In the event of accidental
contact, rinse off with water. If the
liquid gets into eyes, seek medical
assistance. Leaking battery uid may
cause skin irritations or burns.
6) SERVICE
Have your power tool serviced by
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the power
tool is maintained.
7) SPECIAL SAFETY DIRECTIONS FOR
BATTERY-OPERATED TOOLS
a) Ensure that the device is switched
off before inserting the battery.
Inserting a battery into a power tool that is
switched on may result in accidents.
b) Recharge the batteries indoors
only because the battery charger
is designed for indoor use only.
c) To reduce the electric shock haz-
ard, unplug the battery charger
from the mains before cleaning
the charger.
d) Do not subject the battery to
strong sunlight over long periods
and do not leave it on a heater.
Heat damages the battery and there is a
risk of explosion.
e) Allow a hot battery to cool before
charging.
f) Do not open up the battery and
avoid mechanical damage to the
battery. Risk of short circuit and fumes
may be emitted that irritate the respiratory
tract. Ensure fresh air and seek medical as-
sistance in the event of discomfort.
g) Do not use non-rechargeable bat-
teries!
8) CORRECT HANDLING OFTHE BAT-
TERYCHARGER
a) This device can be used by children
aged 8 and over and by people with
reduced physical, sensory or mental

j) Do not operate the charger on a
combustible surface (e.g. paper,
textiles). Risk of re due to heating dur-
ing charging.
k) If the power cable for this equipment is
damaged, it must be replaced by the
manufacturer, a customer service agent of
the same or a similarly qualied person in
order to prevent hazards.
l) The battery of the appliance is not fully
charged at the time of delivery. It therefore
needs to be fully recharged before you use
it for the rst time. For the rst recharge
cycle we recommend that you charge the
battery for about 1 hour. Slot the battery
into the base and plug the battery charger
into a mains outlet.

tric tool generates an electromagnetic

12
GB IE
eld which, under certain circum-
stances, may impair the functionality of
active or passive medical implants. To
reduce the risk of serious or lethal inju-
ries, we recommend that persons with
medical implants consult their doctor
and the manufacturer of their medical
implant before operating the machine.
Safety instructions for all ap-
plications
Common safety instructions for
grinding, sanding, working with
wire brushes and cutting grinders:
• This electric tool is to be used as
a grinder, sander, wire brush
and cutting grinder. Follow all
safety instructions, directives, il-
lustrations and facts which you
receive with the device. If you do
not follow these instructions, an electri-
cal shock, re and/or serious injury
may occur.
• This electric tool is not suitable
for cup brushes. Using the electric
tool in ways for which it is not intended
may cause hazards and injuries.
• This electric tool is not suitable
for cup wheels, mounted points
or grinding cones. Using the electric
tool in ways for which it is not intended
may cause hazards and injuries.
• This electric tool is not suitable
for polishing. Using the electric tool
in ways for which it is not intended may
cause hazards and injuries.
• Do not use any accessories that
are not specically intended and
recommended for this electric
tool by the manufacturer. Simply
because an accessory can be attached
to your electric tool does not guarantee
safe operation.
• The allowable rotation speed of
the attachment tools must be at
least as high as the highest rota-
tion speed indicated on the elec-
tric tool. Accessories that run faster
than the allowable speed can break
and y apart.
• The outside diameter and thick-
ness of the attachment tool must
correspond to the dimensions
indicated for your electric tool.
Attachment tools which are wrongly
dimensioned cannot be sufciently
shielded or controlled.
• Attachment tools with threaded
attachment must t the thread-
ing of the grinding spindle ex-
actly. For attachment tools which
are mounted through a ange,
the diameter of the hole in the
attachment tool must t the
mounting diameter of the ange.
Attachment tools which cannot be pre-
cisely attached to the electric tool turn
unevenly, vibrate very strongly and can
ultimately lead to a loss of control.
• Never use damaged attachment
tools. Check attachment tools
such as grinding discs for chip-
ping or cracks, grinding plates
for cracks, wear or strong abra-
sion and wire brushes for loose
or broken wires before using
them. If the electric tool or the
attachment tool falls off, check
whether it is damaged or, use
an undamaged attachment tool.
If you have checked the at-
tachment tool and attached it,
keep yourself and any nearby
persons beyond the level of the
rotating attachment tool and al-
low the device to run for 1 min.

13
GB IE
at the highest rotational speed.
Damaged tools usually break during this
test period.
• Wear personal safety equip-
ment. Depending on the applica-
tion, use full face shields, eye
protection or safety goggles.
In so far as it is appropriate,
wear dust masks, ear protec-
tion, gloves or special aprons
which keep small grinding and
material particles away from
you. Eyes should be protected from the
foreign matter which can be caused to
y during the various applications. Dust
or breathing masks should lter the dust
that is created during operation. If you
are exposed to loud noise for a long
time, you may suffer hearing loss.
• Ensure that other people are at
a safe distance to your work-
ing area. Anyone who enters
the working area should wear
personal protective equipment.
Broken bits from the piece being worked
or broken attachment tools can y away
and cause injuries even beyond the di-
rect working area.
• Hold the electric tool only by
the insulated gripping surfaces
when performing work in which
the cutting tool may come into
contact with hidden wiring or its
own cord. Contact with a live wire
can also cause a charge in metal parts
of the device and result in an electric
shock.
• Keep the cord away from the ro-
tating attachment tool. If you lose
control of the device, the power cord
can become separated or caught and
your hand or arm may be pulled into
the rotating attachment tool.
• Never put the electric tool down
before the attachment tool has
come to a full stop. The rotating
attachment tool can come into contact
with the surface upon which it is set,
whereby you could lose control of the
electric tool.
• Never allow the electric tool to
run whilst you are carrying it.
Your clothing may accidentally come
into contact with the rotating attachment
tool and get caught and the attachment
tool could drill into your body.
• Clean the ventilation slots of
your electric tool routinely. The
motor air pulls dust into the housing
and, should too much metallic dust col-
lect, could cause electrical hazards.
• Never use the electric tool near
ammable material. Sparks could
ignite this material.
• Do not use attachment tools
which require liquid coolant.
Using water or another liquid coolant
could lead to electrical shock.
Additional safety instructions
• Connect the appliance only to a power
socket with a residual current circuit
breaker of rated residual current no
more than 30 mA.
• Keep power cords and extension cords
away from the disc. If they are dam-
aged or cut through, immediately pull
the plug from the outlet. Do not touch
the cable before it has been discon-
nected from the power supply.
Risk of electric shock!
• The replacement of the plug or the con-
nection line must always be executed
by the manufacturer of the electric tool
or his/her customer service in order to
avoid any hazards.
• Only use grinding discs where the in-

14
GB IE
dicated rotational speed is at least as
high as what has been specied on the
name plate of the device.
• Carry out a visual inspection of the
grinding disc before use. Do not use
any damaged or deformed grinding
discs. Replace any damaged or worn
grinding discs.
• Make sure that the sparks produced by
grinding do not present a danger, e.g.
reach people or ignite ammable sub-
stances.
• Always wear safety goggles, safety
gloves, respiratory protection and ear
protection when grinding, brushing and
cutting.
• Never keep the ngers between the
grinding disc and spark protection or in
close proximity to the protective hoods.
There is a risk of crushing.
• The rotating parts of the device cannot
be covered due to functional reasons.
Therefore, proceed cautiously and hold
the workpiece rmly in order to avoid
slipping which could cause your hands to
come into contact with the grinding disc.
• The workpiece gets hot during grind-
ing. Do not touch the machined area,
allow it to cool down. There is a risk of
burning. Do not use coolants or the like.
• If you are tired or have consumed al-
cohol or tablets, do not work with the
device. Always have a break on time.
• Turn off the appliance and, before do-
ing any servicing, remove the battery.
RESIDUAL RISKS
Even if properly operating and handling this
electric tool, some residual risks will remain.
Due to its construction and build, this electric
tool may present the following hazards:
a) Cuts
b) Ear damage if working without ear pro-
tection.
c) Damage to your health caused by swing-
ing your hands and arms when operat-
ing the appliance for longer periods of
time or if the unit is not held or main-
tained properly.
d) Health injuries which result from swing-
ing hand and arm, in the event that the
device is used over a longer period
of time or is not used and maintained
properly.
Warning! During operation, this elec-
tric tool generates an electromagnetic
eld which, under certain circum-
stances, may impair the functionality
of active or passive medical implants.
To reduce the risk of serious or lethal
injuries, we recommend that persons
with medical implants consult their
doctor and the manufacturer of their
medical implant before operating the
machine.
Kickback
Kickback is the sudden reaction from a chop-
ping or blocked grinder attachment such as a
grinding disc, grinding plate, wire brush etc.
Chopping or blocking leads to sudden stop-
ping of the rotating attachment. This causes
an uncontrolled electric tool to accelerate in a
direction counter to the rotational direction of
the attachment tool. If, for example, a grind-
ing disc cuts into the workpiece or blocks it,
the edge of the grinding disc that digs into
the workpiece can get caught and, through
that, break off the grinding disc or cause a
kickback. The grinding disc then moves to-
wards or away from the operator, depending
on the direction of rotation of the disc at the
blocked spot. Here, the grinding discs can
also break. A kickback is caused by wrongly
or incorrectly operating the electric tool. It can
be avoided by suitable cautionary measures,

such as described below.
a) Hold the electric tool very
rmly and bring your body and your
arm into a position in which you can
resist the kickback force. Always use
the supplemental handle if available to
give you the best control over kickback
force or reaction time during accel-
eration. The operator can master the
kickback and reaction force through
suitable precautions.
b) Never bring your hands near a
rotating attachment tool. The at-
tachment tool can run over your hand
in the kickback.
c) Keep your body away from the
area in which the electric tool
would move during a kickback.
The kickback drives the electric tool in
the counter-direction to the rotation of
the grinding disc at the blocked spot.
d) Work particularly cautiously in
corner areas or where there are
sharp corners etc. Prevent the at-
tachment tools from recoiling from the
workpiece and jamming. The rotating
attachment tool tends to jam when near
corners, sharp edges or when it recoils
from such. This causes a loss of control
or kickback.
e) Do not use chain or toothed
saw blades. Such attachment tools
frequently cause a kickback or loss of
control over the electric tool.
Special safety instructions for
grinding and cutting
a) Use only grinders which have
been approved for your electric
tool and the protective hood in-
tended for these grinders. Grind-
ers which are not intended for the elec-
tric tool may not be sufciently shielded
and are unsafe.
b) Depressed centre grinding
wheels must be pre-mounted in
such a way that their grinding
surface does not protrude over
the level of the edge of the pro-
tective cover. An incorrectly mounted
grinding wheel which protrudes beyond
the level of the edge of the protective
cover cannot be adequately shielded.
c) The protective hood must be
securely attached to the elec-
tric tool and adjusted so that
the greatest level of safety is
reached, i.e., the smallest possible
amount of the grinder is exposed to the
operator. The protective hood should
protect the operator from broken bits
and accidental contact with the grinder.
d) Grinders may only be used for
the recommended attachment
options. For example: Never grind
with the side surface of a cutting disc.
Cutting discs are for cutting material
using the edge of the disc. Pushing
sideways on these grinders can break
them.
e) Always use undamaged clamp-
ing anges of the correct size
and shape for the grinding disc
you selected. Suitable anges sup-
port the grinding disc and thus reduce
the danger of the grinding disc break-
ing. Flanges for cutting discs can be
distinguished from anges for other
grinding discs.
f) Do not use worn grinding discs
for larger electric tools. Grinding
discs for larger electric tools are not
set up for the higher rotation speeds of

16
GB IE
smaller electric tools and can break.
Other special safety instructions for
cutting grinding
a) Avoid blocking the cutting disc
or pressing down too hard. Do
not make any excessively deep cuts.
Overloading the cutting disc increases
wear and its tendency to tilt or block
and, with that, to kickback or break the
grinder.
b) Avoid the area in front of and
behind the rotating cutting disc.
When you move the cutting disc by
itself in the workpiece, in the event that
the electric tool kicks back with the ro-
tating disc, it can spin directly towards
you.
c) If the cutting disc jams, or you
interrupt your work, switch the
device off and hold it until the
disc has come to a full stop.
Never try to pull the cutting disc out of
the cut while it is still running, because
it can kick back. Identify and correct
the cause of the jamming.
d) Do not switch the electric tool
on again as long as it is in the
workpiece. Allow the cutting disc
to rst reach its full rotational speed
before you carefully resume with the
cutting. Otherwise, the disc may catch,
spring away from the workpiece or
cause a kickback.
e) Support plates or workpieces
to reduce the risk of kickback
from a jammed cutting disc. Large
workpieces may bend under their own
weight. The workpiece must be sup-
ported on both sides of the disc, near
the cutting disc as well as also at the
edge.
f) Be particularly careful for pocket
cuts in existing walls or other
areas where you cannot see
what is there. The cutting disc may
cause a kickback when it cuts into gas
or water lines, electrical lines or other
hidden objects.
Additional safety instructions for
sanding
Special safety instructions for sanding:
• Do not use overly large sandpa-
per sheets; follow the manufac-
turer‘s information for sandpa-
per sizes. Sandpaper sheets which
extend beyond the sanding plate can
cause injuries and can block, tear the
sandpaper, or cause kickback.
Additional safety instructions for
working with wire brushes
Special safety instructions for working with
wire brushes:
• Be aware that the wire brushes
also lose wire pieces during
typical use. Do not overload
the wires by pressing down too
hard. Flying wire pieces can very eas-
ily penetrate thin clothing and/or your
skin.
• If a protective hood is recom-
mended, do not allow the wire
brushes and the protective hood
to touch each other. The diameter of
plate and cup brushes can enlarge if too
much pressure and centrifugal force is
exerted.

Practical tips
Scrubbing wheels:
Never use a cutting wheel for
scrubbing !
Exert only moderate pressure on the work-
piece. Move the device evenly back and
forth.
A working angle of 30° to 40° achieves
the best results for scrub grinding.
Cutting disc:
Never use a scrubbing wheel
for cutting !
Only certied, bre-reinforced cutting or
grinding discs may be used.
In general, work with small scrubs. Exert
only moderate pressure on the workpiece.
Always work in the counter-direction. This
ensures that the device is not pushed out of
the cut through lack of control.
Cutting of stone materials:
• It is best to use a diamond cutting disc
to cut stone materials. Make sure in any
case that the cutting disc is suitable and
labelled for your application.
• When cutting stone materials, ensure
that the dust extraction is sufcient.
• Wear a dust protection mask.
• The device may only be used for dry
cutting/dry grinding.
Information on building statics:
Slits in structural walls are subject to the
standard DIN 1053 Part 1 or country-
specic regulations. These regulations must
be observed without fail. Before begin-
ning work you should ask the structural
engineer, architect or relevant construction
supervisor for advice.

Operation
Caution! Risk of injury!
- Always remove the mains plug
before working on the tool.
- Only use grinding discs and ac-
cessories recommended by the
manufacturer. Using other attach-
ment tools and other accessories
can represent a risk of injury for
you.
- Only use grinding tools which
bear information about the
manufacturer, type of binding,
dimension and permitted number
of revolutions.
- Only use grinding discs where
the printed rotational speed is at

20
GB IE
least as high as what has been
specied on the name plate of
the device.
- Do not use any broken, cracked,
or otherwise damaged grinding
discs.
- Never operate the device with-
out protective equipment.
- Support plates or workpieces to
reduce the risk of kickback from
a jammed cutting disc. Large
workpieces may bend under
their own weight. The workpiece
must be supported on both sides
of the disc, near the cutting disc
as well as at the edge.
Keep your hands away from
the disc when the device is in
operation. Risk of injury.
Information on replace-
ment:
• Never operate the device without
protective equipment.
• Ensure that the rotation speed
stated on the grinding disc is the
same or higher than the nominal
rotation speed of the device.
• Ensure that the grinding disc
dimensions match those of the
device.
• Only use awless grinding discs
(ringing test: when you strike the
grinding disc with a plastic ham-
mer, it results in a clear sound).
• Never re-drill a locating hole
which is too small to make it
larger.
• Never use separate bushings or
adapters in order to make grind-
ing discs with a hole that is too
large t the device.
• Do not use any saw blades.
• To clamp the grinding tools
only use the clamping ange
provided. The pads between the
clamping ange and the grind-
ing tools must be made of elastic
materials e.g., rubber, soft card-
board etc.
• Always reassemble the device
completely after replacing the
grinding disc.
Turn off the appliance and, before
doing any servicing, remove the
battery.
Wear protective gloves when chang-
ing the grinding discs in order to
avoid cutting damages.
The grinding disc nut must not be
screwed too tightly in order to
avoid breaking the disc and nut.
