g. Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions
and the work to be performed. Use of the power tool
for operations different from those intended could result
in a hazardous situation.
5. Service
a. 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.
Additional safety instructions for impact drills
Wear ear protectors with impact drills. Exposure to
noise can cause hearing loss.
Use auxiliary handles supplied with the tool. Loss of
control can cause personal injury.
Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed metal
parts of the power tool "live" and shock the operator.
Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body leaves it unstable
and may lead to loss of control.
Before drilling into walls, floors or ceilings check for the
location of wiring and pipes.
Avoid touching the tip of a drill bit just after drilling, as it
may be hot.
Electrical safety
This tool is double insulated; therefore no earth wire
is required. Always check that the power supply
corresponds to the voltage on the rating plate.
This appliance is not intended for use by young or infirm
persons without supervision. Children must be supervised
to ensure they do not play with the appliance.
If the supply cord is damaged, it must be replaced by the
