5 Safety instructions
NOTE
The safety rules in section 5.1 contain all general safety rules for power tools which, in accordance with the applicable standards, require to be listed in the operating instructions. Accordingly, some of the rules listed may not be relevant to this tool.
5.1 General power tool safety warnings
a)
WARNING
Read all safety warnings and 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.

Printed: 18.04.2017 | Doc-Nr: PUB / 5128952 / 000 / 00Printed: 18.04.2017 | Doc-Nr: PUB / 5128952 / 000 / 01
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery­operated (cordless) power tool.
5.1.1Workareasafety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive atmo-
spheres, 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 operat-
ing a power tool. Distractions can cause you to lose control.
5.1.2 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. Un-
modified 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 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 condi-
tions. 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
theriskofelectricshock.
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.
5.1.3 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 turn-
ing 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 bal-
ance 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.
collection can reduce dust-related hazards.
5.1.4 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
preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of chil-
dren and do not allow 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 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.
f) Keep cutting tools sharp and clean. Properly main-
tained 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 opera-
tions different from those intended could result in a hazardous situation.
5.1.5 Battery tool use and care
a) 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.
b) Use power tools only with specifically designated
battery packs. Use of any other battery packs may create a risk of injury and fire.

c) 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.
d) Under abusive conditions, liquid may be ejected
en
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.
5.1.6 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.
5.2 Drill safety warnings
a) Wear ear protectors when impact drilling. Expo-
sure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tools by insulated gripping surfaces
when performing an operation where the cutting tool may contact hidden wiring. Contact with a
"live" wire will make exposed metal parts of the tool "live" and shock the operator.
5.3 Additional safety instructions
5.3.1 Personal safety
a) Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener may contact hidden wiring. Fasteners contacting
a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
b) Keep the grips dry, clean and free from oil and
grease.
c) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers during breaks between working.
d) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
e) Activate the safety lock (forward / reverse switch
in the middle position) before storing or trans­porting the power tool.
f) Children must be instructed not to play with the
power tool.
g) The power tool is not intended for use by children,
by debilitated persons or those who have received no instruction or training.
h) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known to cause cancer, birth defects, infertility or other reproductive harm; or serious and permanent res­piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry products and natural stone, arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce exposure to these
chemicals, the operator and bystanders should work in a well-ventilated area, work with ap­proved safety equipment, such as respiratory pro­tection appropriate for the type of dust generated, and designed to filter out microscopic particles and direct dust away from the face and body. Avoid prolonged contact with dust. Wear protec­tive clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth,
eyes, or to remain on your skin may promote absorp­tion of harmful chemicals.
5.3.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain free to operate the power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured in the chuck correctly.
5.3.3 Battery tool use and care
a) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
b) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over 80°C. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
c) Do not use batteries other than those approved
for use with the applicable power tool or appli­ance. Use of other batteries or use of the battery for
purposes for which it is not intended presents a risk of fire and explosion.
d) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
e) Avoid short-circuiting the battery. Check that the
terminals on the battery and in the power tool are free from foreign objects before inserting the battery in the power tool. Short circuiting the bat-
tery terminals presents a risk of fire, explosion and chemical burns.
f) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts, bent or pushed-in and/or pulled-out contacts).
5.3.4 Electrical safety
Before beginning work, check the working area (e.g. using a metal detector) to ensure that no concealed electric cables or gas and water pipes are present.
External metal parts of the power tool may become
