Safety instructions when using long drill bits with rotary
hammers
Always start drilling at low speed and with the bit tip
u
in contact with the workpiece. At higher speeds, the bit
is likely to bend if allowed to rotate freely without contact-
ing the workpiece, resulting in personal injury.
Apply pressure only in direct line with the bit and do
u
not apply excessive pressure. Bits can bend, causing
breakage or loss of control, resulting in personal injury.
Additional safety information
Use suitable detectors to determine if there are hid-
u
den supply lines or contact the local utility company
for assistance. Contact with electric cables can cause
fire and electric shock. Damaging gas lines can lead to ex-
plosion. Breaking water pipes causes property damage.
Always wait until the power tool has come to a com-
u
plete stop before placing it down. The application tool
can jam and cause you to lose control of the power tool.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
In case of damage and improper use of the battery, va-
u
pours may be emitted. The battery can set alight or ex-
plode. Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
Do not open the battery. There is a risk of short-circuit-
u
ing.
The battery can be damaged by pointed objects such
u
as nails or screwdrivers or by force applied externally.
An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
Only use the battery with products from the manufac-
u
turer. This is the only way in which you can protect the
battery against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.
Do not touch any application tools or adjacent housing
u
components shortly after operation. These can become
very hot during operation and cause burns.
The application tool may jam during drilling. Make
u
sure you have a stable footing and hold the power tool
firmly with both hands. Otherwise you could lose con-
trol of the power tool.
Take care when carrying out demolition work using
u
the chisel. Falling fragments of the demolition material
could injure you or any bystanders.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool can be
more securely guided with both hands.
Caution! When using the power tool with Bluetooth
u
fault may occur in other devices and systems, aero-
planes and medical devices (e.g. pacemakers, hearing

aids). Also, damage to people and animals in the im-
mediate vicinity cannot be completely excluded. Do
not use the power tool with Bluetooth
medical devices, petrol stations, chemical plants,
areas with a potentially explosive atmosphere or in
blasting areas. Do not use the power tool with
®
Bluetooth in aircraft. Avoid using the product near
your body for extended periods.
