Safety
General Power Tool Safety Warnings
Warning
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below 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 battery-operated (cordless)
power tool.
General Power Tool Safety Warnings– Work area
safety
•Keep work area clean and well lit. Clutter or dark areas
invite accidents.
•Do not operate power tools in explosive atmosphere,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
•Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
General Power Tool Safety Warnings– Electrical
safety
•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.
•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.
•Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
•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.
•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.
•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.
General Power Tool Safety Warnings– Personal
safety
•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.
Use personal protective equipment. Always
wear eye protection. Protective equipment such
as a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
•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.
•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.
•Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situation.
•Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
•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.
•Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool
safety principles. A careless action can cause severe
injury within a fraction of a second.
General Power Tool Safety Warnings– Power tool
use and care
•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.
•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.

4 EN
cordless rotary hammer PRDS 20-20V
•Disconnect the plug from the power source and/or
remove the battery pack, if detachable, 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.
•Store idle power tools out of the reach of children 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.
•Maintain power tools and accessories. 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.
•Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
•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.
•Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
General Power Tool Safety Warnings– Battery tool
use and care
•Recharge only with 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.
•Use power tools only with specifically designed battery
packs. Use of any other battery packs may create a risk of
injury and fire.
•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.
•Under abusive conditions, liquid may be ejected 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.
•Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
•Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
•Follow all charging instructions and do not charge the
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outsides the specified range may damage
the battery and increase the risk of fire.
General Power Tool Safety Warnings– Service
•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.
•Never service damaged battery pack. Service of battery
packs should only be performed by the manufacturer or
authorized service providers.
Device-specific safety warnings for rotary hammers
Wear eye and mouth protection when processing
materials that may contain harmful substances (e.g.
asbestos).
Wear ear protectors when impact drilling. Exposure
to noise can cause hearing loss.
•Use the auxiliary handle(s). Loss of control can cause
personal injury.
•Hold the power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory or fasteners may contact hidden wiring or
its own cord. Cutting accessory contacting a "live" wire
may make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
•Use appropriate detection equipment to track down
concealed supply lines or consult the local utility
companies. Contact with electrical lines may result in fire
and electric shock. Damaging a gas line may lead to an
explosion. Penetrating a water line causes property
damage and may cause an electric shock.
•Vibrations can be harmful to the human hand-arm
system. Keep the vibration exposure time to a minimum.

EN 5
cordless rotary hammer PRDS 20-20V
•During operation hold onto the power tool with both
hands. Make sure that you stand firmly on the ground. It is
safer to handle the power tool with two hands.
•Secure the workpiece. The grip of tensioning devices or a
vice is more secure than holding the workpiece only by
hand.
Protect yourself and others present from injuries
caused by splintering and flying bits and pieces.
Wear a hard hat, eye protection, a dust mask and safety
boots. If necessary, put up partition panels as shield
against breaking off debris.
•Before starting to work, always make sure that the
insertion tool is firmly clamped inside the drill chuck.
Insertion tools that are not locked in place could be
catapulted out of the power tool upon switch-on and lead
to injuries.
•Before switching on the power tool, ensure that the
insertion tool can move freely. If the device is switched
on with a jammed insertion tool, the resulting forces can
be extreme causing the device to kick out sideways.
•Immediately switch off the power tool if the insertion
tool blocks. The power tool can lash out to the side owing
to the forces that build up consequently.
•Regularly check the drill chuck for wear or damage.
•Only start a percussive power tool while holding it
against a workpiece (wall, ceiling, etc.).
•Wait until the power tool has come to a standstill,
before putting it down.
•For any work on the device, as well as during transport
or storage, set the switch for the rotational direction to
centre position (locked). This prevents unintentional
starting of the power tool.
•Processing metal creates flying sparks. Make sure that
nobody's safety is jeopardized and that there are no
combustible materials near the working area. Fire hazard!
•Avoid drilling in lead paint or other harmful materials.
•Always keep the power cable behind the device.
•Make sure that the venting slots are not covered
during operation. Do not insert any objects into the
venting slots.
•The device must always be clean, dry and free from oil
or greases.
Safety instructions when using long drill bits
•Never operate at higher speed than the maximum
speed rating of the drill bit. At higher speeds, the bit is
likely to bend if allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
•Always start drilling at low speed and with the bit tip
in contact with the workpiece. At higher speeds, the bit
is likely to bend if allowed to rotate freely without
contacting the workpiece, resulting in personal injury.
•Apply pressure only in direct line with the bit and do
not apply excessive pressure. Bits can bend causing
breakage or loss of control, resulting in personal injury.

• Take short breaks regularly during drilling. When doing so,
take the drill bit out of the drill hole so that the drill bit can
cool down.
• Secure the workpiece in a tensioning device or vice.
• Select the speed depending on the material characteristics
and the size of the drill bit:
– High speed for small drilling diameter or soft material
– Low speed for large drilling diameter or hard material
• Use a suitable aid to mark the intended location of the drill
hole.
• Select a low speed for spudding.
Drilling in metal:
• Use suitable metal drill bits (e.g. drill bits made of high-
speed steel (HSS)).
• For larger drilling diameters, use a smaller drill bit for pre-
drilling.
• To achieve ideal results, the drill bit should be cooled with
a suitable lubricant.
• Metal drill bits may also be used for drilling in plastic.
Drilling in wood:
• Use drill bits suitable for wood.
• Place a block of wood under the workpiece or drill in from
both sides so that the wood cannot break off when it is
being drilled through.
• Use a wood drill bit with centring tip. For deep drill holes,
use an auger bit; for large drilling diameters, use a
Forstner bit.
Hammer drilling in masonry / bricks:
• Use a drill bit suitable for masonry / bricks.
Screwing:
• When using screwdriver bits, always use a universal bit
holder. Only use screwdriver bits that are suitable for the
screw head.
