Bosch GSB Professional 780 Notice Originale page 13

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
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.
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 utility lines are
u
hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
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.
