in a safe place for future reference!
The term “electrical tool” used in the safety advice
refers to electrical tools powered by mains electricity (by means of a mains lead) and electrical tools
powered by rechargeable batteries (without a
mains lead).
1. Workplace safety
a) Keep your working area clean and
well lit. Untidy or poorly lit working areas
can lead to accidents.
b)
Do not work with the device
in potentially explosive environments in which there are
inflammable liquids, gases or dusts.
Electrical power tools create sparks, which can
ignite dusts or fumes.
c)
Keep children and other
people away while you are
operating the electrical tool.
Distractions can cause you to lose control of
the device.
2. Electrical safety
a)
The mains plug on the device must match
the mains socket. The plug must not
be modified in any way. Do not use
an adapter plug with devices fitted

you are doing and always proceed
with caution. Do not use the device if
you are tired or under the influence of
drugs, alcohol or medication. One mo
of carelessness when using the device can lead
to serious injury.
b)
personal protective equipment such as dust
8 GB/IE
Wear personal protective
equipment and always wear
safety glasses. The wearing of
masks, non-slip safety shoes, safety helmets or
ment
ear protectors, appropriate to the type of electrical power tool used and work undertaken,
reduces the risk of injury.
c) Avoid unintentional operation of the
device. Check that the electrical power
tool is switched off before you connect
it to the mains, pick it up or carry it.
Accidents can happen if you carry the device
with your finger on the ON / OFF switch or with
the device switched on.
d) Remove any setting tools or spanners
before you switch the device on. A tool
or spanner left attached to a rotating part of a

4. Careful handling and use
of electrical power tools
a) Do not overload the device. Always
use an electrical power tool that is
intended for the task you are undertaking. By using the right electrical power
tool for the job you will work more safely and
achieve a better result.
b) Do not use an electrical power tool if
its switch is defective. An electrical power
tool that can no longer be switched on and off
is dangerous and must be repaired.
c) Pull the mains plug from the socket
before you make any adjustments to
the device, change accessories or when
the device is put away. This precaution is
General safety advice for electrical power tools
intended to prevent you from unintentionally
starting the device.
d) When not in use always ensure that
electrical power tools are kept out of
reach of children. Do not let anyone use
the device if he or she is not familiar
with it or has not read the instructions
and advice. Electrical power tools are dan-
gerous when they are used by inexperienced
people.
e) Look after the device carefully. Check
that moving parts are working properly and move freely. Check for any
parts that are broken or damaged
enough to detrimentally affect the
functioning of the device. Have damaged parts repaired before you use
the device. Many accidents have their origins
in poorly maintained electrical power tools.
f) Keep cutting tools clean and sharp.
Carefully maintained cutting tools with sharp
cutting edges are less likely to jam and are
easier to control.
g) Use the electrical power tool, accesso-
ries, inserted tools etc. in accordance
with these instructions and advice, and
the stipulations drawn up for this particular type of device. In doing this, take
into account the working conditions
and the task in hand. The use of electrical
power tools for purposes other than those intended can lead to dangerous situations.
Safety advice for all uses
General safety advice for grinding,
sanding (with sandpaper), wire brushing,
polishing and disc-cutting:
a) This electrical power tool is intended
for use as a grinding, sanding, wirebrushing, and disc-cutting machine.
Observe all the safety advice, instructions, information in figures and all
other information you received with
this device. If you do not observe the following
advice it could lead to electric shock, fire
and / or serious injury.
b) Normative statement / advice for this tool is not
applicable.
c) Do not use any accessory not specifi-
cally intended by the manufacturer
for this electrical power tool. Although
an accessory may fit on your electrical power
tool, this does not on its own guarantee that it
can be safely used.
d) The maximum permitted speed of an
attachment must be at least as high as
the maximum speed indicated for the
electrical power tool. An accessory rotating
faster than its permitted speed could disintegrate
or fly off.
e) The external diameter and the thickness
of the attachment must be compatible
with the dimensions of your electrical
power tool. Attachments that are not dimen-
sionally compatible cannot be adequately
guarded or controlled.
f) Grinding discs, flanges, grinding
wheels or other accessories must fit
exactly on to the spindle of your electrical power tool. Attachments that do not
exactly fit on the spindle turn unevenly, vibrate
severely and could lead to loss of control.
g) Do not use damaged attachments.
Before every use check attachments
such as grinding discs for loose fragments and cracks, grinding wheels for
cracks, deterioration or excessive
wear and wire brushes for loose or
broken wires. If the electrical power
tool or attachment is dropped, inspect
for damage or change the attachment
for an undamaged one. When you
have inspected and inserted the attachment, position yourself and bystanders away from the plane of the
rotating attachment and run the device
at maximum speed for one minute.
Damaged attachments will usually break apart
during this test.
h)
Wear personal protective
equipment. Use a full face visor, safety goggles or safety
9 GB/IE
General safety advice for electrical power tools
glasses, depending on the application.
Wear a dust mask, hearing protectors,
safety gloves or special apron capable
of stopping particles of the grinding
medium or workpiece, as appropriate
for the task. Eyes must be protected from
the flying debris which can arise from some
operations. Dust or breathing masks must be
capable of filtering out the dust generated by
the application. Prolonged exposure to loud
noise can lead to hearing loss.
i) Keep bystanders at a safe distance
from your work area. Anyone entering
the work area must wear personal
protective equipment. Fragments of the
workpiece or of a broken attachment could fly
off and cause injury beyond the immediate
working area.
j) Hold the device by the insulated han-
dle surfaces when you are undertaking work where there is the danger
of the attachment striking hidden
electricity cables or the device’s mains
lead. Contact with a live wire could cause
metal parts of the device to become live and
lead to electric shock.
k) Keep the mains lead away from rotat-
ing attachments. If you lose control of the
device the mains lead may become severed or
trapped and your hand or arm may be pulled
into the rotating attachment.
l) Never lay the electrical power tool
down until after the attachment has
come to a complete standstill. The rotat-
ing attachment may snag when it comes into
contact with the surface and cause you to lose
control of the device.
m) Do not have the electrical power tool
running while you are carrying it. Your
clothing could become trapped by unintentional contact with the rotating attachment and the
tool could be pulled into your body.
n) Clean the ventilation slots on your
electrical power tool regularly. The motor’s fan draws dust into the housing. A build-up
of metal dust could give rise to an electrical
hazard.

these materials.
p) Do not use attachments that require
Safety advice
Never use the electrical
power tool near inflammable
materials. Sparks could ignite
the use of coolants. The use of water or
other liquid coolants could result in electric shock.
relating to kickback
Kickback is the sudden reaction to a pinched or
snagged rotating attachment, such as a grinding
disc, grinding pad, wire brush etc. Pinching or
snagging results in the rotating attachment coming
to an abrupt stop. This causes the electrical power
tool (if not controlled) to move in the opposite direction to the direction of rotation of the attachment
at the point of constraint.
If, for example, a grinding disc is pinched or snags
in a workpiece, this can cause the edge of the
grinding disc to penetrate the workpiece, become
trapped there and either free itself or kickback. The
grinding disc moves towards or away from the operator, depending on the direction of movement of
the disc at the point of constraint. The grinding disc
could also break.
Kickback occurs as a result of incorrect use or misuse of the electrical power tool. It can be prevented
by taking the appropriate precautions as described
below.
a) Maintain a firm grip on the electrical
power tool and position your body
and arms to allow you to resist kickback forces. Always use the auxiliary
handle, if provided, to exercise the
greatest possible control over kickback forces or reaction torques as the
device builds up to full speed. By taking
suitable precautions the operator can control
kickback and reaction forces.
b) Do not place your hands near a rotat-
ing attachment. If kickback occurs the attachment could move over your hand.
General safety advice for electrical power tools
c) Avoid positioning your body in the
area into which the electrical power
tool would move in the event of a
kickback. A kickback moves the electrical
power tool in the opposite direction to the direction of movement of the grinding disc at the
point of constraint.
d) Work particularly carefully in the
area of corners, sharp edges etc. to
avoid the attachment bouncing or
snagging on the workpiece. Corners,
sharp edges or bouncing have a tendency to
snag the rotating attachment. This causes loss
of control or kickback.
e) Do not use saw-chain woodcarving
discs or toothed discs. Such attachments
create frequent kickback and loss of control of
the electrical power tool.
Special safety advice relating
to grinding and disc-cutting
a) Always use the guard designed for
the type of abrasive consumable you
are using. Always use abrasive consumables
approved for use with your electrical power
tool. Abrasive consumables not approved for
use with your electrical power tool cannot be
adequately guarded and are unsafe.
b) To ensure the highest level of opera-
tional safety, the disc guard cover
must be attached to the electrical
power tool and set in such a way that
the smallest possible area of the
abrasive consumable is exposed to
the operator. The disc guard cover is there
to protect the operator from pieces breaking
off and accidental contact with the abrasive
consumable.
c) Abrasive consumables must be used
only for their recommended purposes, For example: never grind with the
side face of a cutting disc. Cutting discs
are intended for removing material using the
edge of the disc. Sideways forces on these
abrasive consumables can cause them to break.
d) Always use an undamaged mounting
flange of the correct size and shape
for your selected grinding disc. Suitable
flanges support the grinding disc and reduce
the chance of it breaking. Flanges for cutting
discs are different from the flanges for other
abrasive discs.
e) Never use worn down abrasive con-
sumables intended for larger electrical
power tools. Abrasive consumables intended
for larger electrical power tools are not designed
for the faster rotational speeds of these smaller
electrical power tools and could break.
Further special safety
advice for disc-cutting
a) Avoid snagging the cutting disc and
do not use too much contact pressure.
Do not attempt to make excessively
deep cuts. Overloading the cutting disc in-
creases the load and the tendency of the disc
to twist or snag in the cut, making kickback or
disc breakage more likely.
b) Avoid the area in front of or behind
the rotating cutting disc. If the cutting disc
is moving away from you at the point of constraint in the workpiece, then, in the event of
a kickback, the electrical power tool and the
rotating disc may be thrown towards you.
c) If the cutting disc jams or you stop
work for a while, switch the device
off and hold it until the disc comes to
a complete stop. Never attempt to
pull the still rotating cutting disc out of
the cut as this could cause kickback.
Determine and rectify the reason for the jamming.
d) Do not switch on the device if the cut-
ting disc is in the workpiece. Allow
the cutting disc to reach full speed before carefully continuing with the cut.
Otherwise the disc could snag, jump out of the
workpiece or cause a kickback.
e) Support boards or workpieces whilst
cutting to reduce the risk of kickback
caused by a jammed cutting disc. Large
workpieces may bend under their own weight.
