Safety precautions
Caution: The following fundamental safety
precautions must always be observed when
using electric tools/machines as protection
against electric shock, the risk of injury and
fire hazards.
Please read and take note of these precau-
tions before you use the tool/machine.
■
1 Keep your place of work clean and tidy.
Disorder where you are working creates a po-
tential risk of accidents.
■
2 Make allowance for influence from the sur-
roundings. Don't expose your electric tools/ma-
chines to rain. Don't use electric tools/ma-
chines in damp or wet surroundings. Make
sure the work area is well lit. Don't use elec-
tric tools/ machines near inflammable liquids
or gases.
■
3 Always protect yourself against electric
shock. Never touch grounding (earthing) parts
e.g. pipes, radiators, cookers, ovens, refrig-
erators.
■
4 Keep children away. Don't let other per-
sons touch the electric tool/machine or sup-
ply cord. Keep them away from your work
area.
■
5 Keep your electric tool/machine in a safe
place. Electric tools/machines not in use should
be kept in a dry locked-up place out of the
reach of children.
■
6 Don't overload your electric tools/machines.
You will do your work better and safer in the
specified performance/rating range.

■
7 Always use the right electric tool/machine
for the job. Don't use underpowered tools/ma-
chines or attachments for heavier duty jobs.
Don't use electric tools/ machines for work
and purposes for which they are not intend-
ed, e.g. don't use a hand-held circular saw to
cut down trees or cut up branches.
■
8 Wear suitable clothing. Don't wear loose
clothing or jewellery – they could be caught
up in moving parts. When working outside,
the use of rubber gloves and non-slip shoes
is recommended. Wear a helmet or cap if you
have long hair.
■
9 Always wear protective goggles. If work
causes dust, wear a mask as well.
■
1 0 Don't use the supply cord for any other
purpose. Don't carry the electric tool/ machine
by the supply cord and don't pull the plug out
of the socket/receptacle by pulling the sup-
ply cord. Protect the cable from heat, oil and
sharp edges.
■
1 1 Secure the workpiece. Use a clamping de-
vice or vice to hold the workpiece. It is se-
cured more reliably in this way than in your
hand and you can then hold and operate your
electric tool/machine with both hands.
■
1 2 Don't bend over too far when working.
Avoid an unusual stance. Make sure that you
are standing firmly and keep your balance at
all times.
■
1 3 Take good care of your electric tools/ma-
chines. Keep the drill bits, insert tools etc.
sharp and clean so that you can do your work
better, safer and more reliably. Observe the
cleaning and maintenance regulations and
the instructions for changing drill bits, insert
tools etc. Check the supply cord regularly and
have it renewed by a recognized specialist if
it is damaged. Check the extension supply
cord regularly and, if it is damaged, replace
it. Keep grips and side handles dry and free
from oil or grease.
■
1 4 Always pull out the plug from the mains if
the electric tool/machine is not in use, prior
to cleaning and maintenance work and when
changing a drill bit, saw blade or insert tools
of any kind.
■
1 5 Never leave a key in place. Always check
before switching on that the key or adjusting
tools have been removed.
■
1 6 Avoid any unintentional start-up. Never
carry a plugged-in electric tool/machine with
your finger on the switch. Always make sure
that the switch is off when plugging the elec-
tric tool/machine into the main electric sup-
ply.
■
1 7 If an extension supply cord is used out-
side, only use one which has been approved
for the purpose and is correspondingly marked.
■
1 8 Be attentive at all times. Keep your eye on
your work. Remain in a sensible frame of mind
and don't use the electric tool/machine if you
cannot concentrate completely.
■
1 9 Check your electric tool/machine for dam-
age. You must check the safety devices or
damaged parts carefully for perfect function-
ing in keeping with the intended purpose be-
fore using the electric tool/machine further.
Check whether the moving parts function
properly, whether they aren't sticking, whether

any parts are broken, whether all other parts
work properly and are fitted correctly, and
make sure that all other conditions which can
influence operation and running of the elec-
tric tool/machine are as they should be. Dam-
aged guards and protective devices and parts
must be repaired properly by an authorized
service workshop or replaced provided that
nothing else is stated in the operating in-
structions. Damaged switches must also be
replaced in the recognized service workshop.
