General Power Tool Safety Warnings – Work area
safety
•Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
•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.
•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 or power adapter 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.
• Hold power tool by insulated gripping surfaces when
performing an operation where the cutting accessory
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.
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 protective mask, non-skid safety shoes, hard
hat, hearing protection or tight-fitting protective
clothing 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 situations.

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. 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.
•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.
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.
General Battery Pack / Charger Safety Warnings
•Use power tools only with specifically designated
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.
•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.
•Do not charge other battery packs. The charger is only
suitable for use with the supplied battery pack and with
the voltages specified in the technical data. Otherwise,
there is a risk of fire and explosion.
•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.

Device-specific safety warnings for rotary hammers
Wear eye and mouth protection when processing
materials that may contain harmful substances (e.g.
asbestos).
•Hold the device by its insulated gripping surfaces
when performing an operation where the insertion tool
may contact hidden wiring or its own cord. Cutting 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.
•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 gets jammed. 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.

Operation
Tips and notes on handling the cordless rotary hammer
General information:
• The centre position of the clockwise/counter-clockwise
rotationswitch (lock) is suited for work breaks or (drill) bit
exchange.
Drilling in general:
• 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.
Switching the device on and off
