Drill Safety Warnings; Additional Safety Precautions For Screwdrivers - Hilti SF 4-A22 Manual Del Usuario

▶ Do not expose a battery pack or tool to fire or excessive temperature.
Exposure to fire or temperature above 130° C (265 °F) may cause
explosion.
▶ Follow all charging instructions and do not charge the 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 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 battery packs should
only be performed by the manufacturer or authorized service providers.

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.

2.3 Additional safety precautions for screwdrivers

▶ Always hold the tool firmly with both hands on the grips provided. Keep
the grips clean and dry.
▶ Do not touch rotating parts – risk of injury!
▶ Wear suitable protective glasses, a hard hat, ear protection, protective
gloves and light respiratory protection while using the power tool.
