2.2 Drill safety warnings

Safety instructions for all operations
▶ Hold the power tool by insulated gripping surfaces, when performing
an operation where the cutting accessory or fasteners may contact
hidden wiring. Cutting 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 speed rating of
the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting in personal injury.
▶ Always start drilling at low speed and with the bit tip in contact with
the workpiece. At higher speeds, the bit is likely to bend if allowed
to rotate freely without contacting the workpiece, resulting in personal
injury.
▶ Apply pressure only in direct line with the bit and do not apply
excessive pressure. Bits can bend causing breakage or loss of control,
resulting in personal injury.

cables or gas and water pipes. External metal parts of the product could
give you an electric shock or cause an explosion if you accidentally
damage an electric cable or a gas or water pipe.
