Bosch Professional GFA 18-H Manual page 13

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.
Hammer and Drill Safety Warnings
Safety instructions for all operations
Wear ear protectors. Exposure to noise can cause hear-
u
ing loss.
Use the auxiliary handle(s). Loss of control can cause
u
personal injury.
Brace the tool properly before use. This tool produces a
u
high output torque and without properly bracing the tool
during operation, loss of control may occur resulting in
personal injury.
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 information
Use auxiliary handle(s), if supplied with the tool. Loss
u
of control can cause personal injury.
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.
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
Bosch Power Tools
the workpiece or when the power tool becomes over-
loaded.
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.
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.
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.
Additional safety instructions and working
advice
Before any work on the power tool (e.g. maintenance,
u
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the middle
position. There is risk of injury from unintentionally
pressing the on/off switch.
If the application tool should become blocked, switch
u
the power tool off. Loosen the application tool.
Switching on when the drilling tool is blocked may
u
cause high torque reactions.
Avoid switching on the tool accidentally. Make sure
u
that the on/off switch is set to the off position before
