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.
Save all warnings and instructions for future
reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or batteryoperated (cordless) power tool.
1. Work area safety
a) Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2. Electrical safety
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. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or ground-
ed surfaces, such as pipes, radiators, ranges
and refrigerators. 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 electric shock.
e) 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.
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.
3. Personal safety
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 influence of drugs, alcohol
or medication. A moment of inattention while
operating power tools may result in serious
personal injury.
b) 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.
c) 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.
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, jewel-
lery 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 adjustments, changing accessories, or storing power tools. Such preven-
tive safety measures reduce the risk of starting
the power tool accidentally.
d) Store idle power tools out of the reach of
children. Do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are dan-
gerous in the hands of untrained users.
e) Maintain power tools. Check for misalign-
ment 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 ac-
cidents are caused by poorly maintained power
tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely 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 different
from those intended could result in a hazardous
situation.
5. Use and handling of the cordless
electrical power tool
a) Charge a rechargeable battery unit using only
the charger recommended by the manufacturer. Chargers are often designed for a particular
type of rechargeable battery unit. There is the
danger of fire if other types of rechargeable
battery units are used.
b) Only the rechargeable battery units supplied
are to be used with an electrical power tool.
The use of other rechargeable battery units may
lead to the danger of injury or fire.
c) When they are not being used, store re-
chargeable battery units away from paperclips, coins, keys, nails, screws or other small
metal objects that could cause the contacts
to be bridged. Short-circuiting the contacts of
a rechargeable battery unit may result in heat
damage or fire.
d) Fluids may leak out of rechargeable battery
units if they are misused. If this happens,
avoid contact with the fluid. If contact occurs,
flush the affected area with water. Seek additional medical help if any of the fluid gets into
your eyes. Escaping battery fluid may cause
skin irritation or burns.
CAUTION! RISK OF EXPLOSION!
Never charge non-rechargeable
batteries!
Protect the rechargeable battery
from heat, for example from continuous exposure to sunlight, fire,
water and moisture. There is a risk of
explosion.

6. Service
a) 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.
Safety instructions for all applications
Special safety instructions for grinding and
abrasive cutting:
a) This power tool is to be used as a grinder and
abrasive cutting appliance. Please follow all
safety instructions, instructions, diagrams and
data that you receive with the appliance. If
you do not observe the following instructions,
this can lead to an electrical shock, fire and/or
serious injuries.
b) This power tool is not suitable for sandpaper
sanding, working with a steel brush or burnishing. Using the power tool for applications
for which it is not designed can lead to hazards
and injuries.
c) Do not use any accessories that have not
been specifically provided or recommended
by the manufacturer for this power tool. Just
because you can attach the accessories to your
power tool, does not ensure they are safe to use.
d) The maximum speed of the accessory tool
used must be at least as high as the maximum
speed specified for the power tool. Accessories
that rotate faster than the permissible rate can
break and throw pieces into the air.
e) The external diameter and thickness of the
accessory tool used must comply with the dimensions of the power tool. Incorrectly dimen-
sioned accessory tools cannot be sufficiently
shielded or controlled.
f) Attachment tools with a thread insert must
match the thread of the grinding spindle exactly. For attachment tools that are mounted
using a flange, the diameter of the hole on
the attachment tool must correspond to the
width of the fitment on the flange. Accessory
tools that cannot be firmly fitted to the power
tool rotate unevenly, vibrate severely and can
lead to a loss of control.
g) Never use damaged accessory tools. Check
accessory tools such as grinding discs before
each use for chips or cracks, grinding plates
for cracks, wearing or excessive wear and
tear and wire brushes for loose or broken
wires. If the power tool or the accessory
tool in use is dropped, check to see if it is
damaged or use an undamaged accessory
tool. When you have checked and inserted
the accessory tool, ensure that you and any
other persons in the vicinity remain outside
the plane of the rotating accessory tool and
allow the tool to rotate at maximum speed
for one minute. Damaged accessories usually
break during the test period.
h) Wear personal protective equipment.
Depending on the application, ensure that
you use full face protection, eye protection
or goggles. Use a dust mask, hearing protection, protective gloves or special apron that
protect you from grindings and material particles as required. Protect your eyes from flying
debris that may be created during certain applications. Dust or filter masks must be used to
filter any dust created by the application. If you
are exposed to loud noise for any length
of time, you may suffer hearing loss.
i) Ensure that other people remain at a safe dis-
tance to your workspace. Anyone who enters
the workspace must wear personal protective
equipment.
Fragments of the workpiece or broken accessory tools can fly off and cause injury – even
outside the immediate working area.
j) Hold the power tool only by the insulated
handles when you are carrying out work
in which the accessory tool may come into
contact with concealed power cables. Contact
with a live cable may also cause metal parts of
the appliance to become live and may result in
an electric shock.
k) Keep the power cord away from any rotating
accessories. If you lose control of the appliance, the cord may get caught or cut and your
hand or arm could get caught in the rotating
accessory tool.
■ 6 │ GB

PWSA 20-Li A1
l) Never put the power tool down until the
accessory tool being used has come to a
complete standstill. The rotating accessory tool
could come into contact with the surface and
cause you to lose control of the power tool.
m) Do not leave the power tool running whilst
carrying it. Accidental contact between your
clothing and the rotating accessory tool could
lead to a physical injury.
n) Clean the ventilation slits of your power tool
regularly. The engine fan draws dust into the
housing, and so a strong accumulation of metal
dust can cause electrical hazards.
o) Never use the power tool in the vicinity of
inflammable materials. Sparks can ignite these
materials.
p) Do not use any accessory tools which require
liquid coolant. The use of water or other liquid
coolants may lead to an electric shock.
Kickback and corresponding safety
instructions
Kickback is a sudden reaction caused when a
rotating accessory tool, e.g. grinding disc, grinding
plate, wire brush, etc., catches or jams. Catching or
jamming leads to an abrupt stop of the rotating accessory tool. If this happens, an uncontrolled power tool turns rapidly against the direction of rotation
of the accessory tool caught in the blockage.
If, for example, a grinding disc catches or jams in a
workpiece, the edge of the grinding disc projecting into
the workpiece can get caught and break off the grinding disc or cause a kickback. The grinding disc can
then fly in the direction of the operator or away from
him, depending on the direction of rotation of the disc
at the blockage. This can also break grinding discs.
A kickback is caused by incorrect use or misuse
of the power tool. This can be avoided by taking
proper precautions as described below.
a) Hold the power tool firmly in both hands and
position your body and arms so they can
absorb the force of a kickback. Always use
the additional handle, if available, so that
you have the maximum possible control over
the kickback force or reaction forces at full
speed. By taking adequate precautions, the
operator can stay in control of the kickback
and reaction torques.
b) Never hold your hand close to a rotating
accessory tool. The accessory tool could hit
your hand in the event of a kickback.
c) Avoid having any part of your body in the
region in which the power tool is likely to
move in event of a kickback. The kickback will
force the power tool in the opposite direction to
the direction of rotation of the grinding disc at
the blockage.
d) Take special care when working near corners,
sharp edges, etc. Avoid allowing the accessory
tool to bounce back from the workpiece or jam.
The rotating accessory tool is more likely to jam in
corners or sharp edges or if it rebounds off them.
This can cause a loss of control or kickback.
e) Do not use chains or toothed saw blades.
Such accessories often cause a kickback or loss
of control over the power tool.
Special safety instructions for grinding
and abrasive cutting
a) Use only the grinding accessories approved
for your power tool and the appropriate blade
guard for these grinding tools. Grinding tools
that are not designed for the power tool cannot
be sufficiently shielded and are unsafe.
b) Offset grinding discs must be fitted so that the
grinding surface does not protrude over the
level of the blade guard edge. An improperly
fitted grinding disc which protrudes over the level
of the blade guard edge cannot be properly
guarded.
c) The blade guard must be securely mounted
on the power tool and adjusted to ensure
maximum safety so that the smallest possible amount of the grinding tool is open to
the operator. The blade guard is designed to
protect the operator from fragments, accidental
contact with the grinding tool and sparks that
could ignite clothing.
d) Grinding tools should only be used for the
recommended applications.
For example: Never grind with the side surface of a cutting disc. Cutting discs are designed
to remove material with the edge of the disc.
Any lateral application of force on these grinding
tools can lead to breakage.
PWSA 20-Li A1
GB│IE│NI │ 7 ■
e) Always use an undamaged clamping flange
of the correct size and shape for the selected
grinding disc. Suitable flanges support the
grinding disc and reduce the risk of disc breakage. Flanges for cutting discs can be different to
flanges for other grinding discs.
f) Do not use worn grinding discs from larger
power tools. Grinding discs for larger power
tools are not designed for the higher rotational
speeds of smaller power tools and so can
break.
Additional special safety instructions
for abrasive cutting
a) Avoid causing blockages to the cutting disc
or high contact pressure. Do not make any
excessively deep cuts. Overloading the cutting
disc increases the stress and likelihood of tilting
or blocking and thus the possibility of a setback
or a breakage of the grinding tool.
b) Avoid the area in front of and behind the
rotating cutting disc. When you move the cutting disc away from yourself in the workpiece,
it is possible, in the event of a kickback, that the
power tool along with the rotating disc might be
thrown out directly towards you.
b) If the cutting disc jams or you stop working,
switch the tool off and hold it steadily in the
workpiece until the disc has completely stopped
turning. Never attempt to pull a rotating cutting
disc out of a cut. This could lead to kickback.
Identify and remove the cause of the jam.
d) Do not switch the power tool back on while it
is located in the workpiece. Allow the cutting
disc to reach its full speed before you carefully
continue the cut. Otherwise, the disc can jam,
jump out of the workpiece or cause kickback.
e) Support boards or large workpieces to re-
duce the risk of the cutting disc jamming and
causing a kickback. Large workpieces can
bend under their own weight. The workpiece
must be supported on both sides of the disc:
both in the vicinity of the cutting disc and also
at the edge.
f) Be particularly careful when making "pocket
cuts" into existing walls or other obscured
areas. The protruding cutting disc may cut gas
or water pipes, electrical wiring or other objects
that can cause a kickback.
