Do not use a battery pack or tool that is damaged or
u
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 excess-
u
ive temperature. Exposure to fire or temperature above
130°C may cause explosion.
Follow all charging instructions and do not charge the
u
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outside the specified range may damage
the battery and increase the risk of fire.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Never service damaged battery packs. Service of bat-
u
tery packs should only be performed by the manufacturer
or authorized service providers.
Safety information for drills and screwdrivers
Safety instructions for all operations
Wear ear protectors when impact drilling. Exposure to
u
noise can cause hearing loss.
Hold the power tool by insulated gripping surfaces,
u
when performing an operation where the cutting ac-
cessory or fasteners may contact hidden wiring. Cut-
ting accessory or fasteners contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Safety instructions when using long drill bits
Never operate at higher speed than the maximum
u
speed rating of the drill bit. At higher speeds, the bit is
likely to bend if allowed to rotate freely without contact-
ing the workpiece, resulting in personal injury.
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 warnings
Hold the power tool securely. When tightening and
u
loosening screws be prepared for temporarily high torque
reactions.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
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.
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.
Switch the power tool off immediately if the applica-
u
tion tool becomes blocked. Be prepared for high
torque reactions which cause kickback. The applica-
tion tool becomes blocked when it becomes jammed in
the workpiece or when the power tool becomes over-
loaded.
