▶ Keep the power tool out of reach of children.
▶ Avoid touching rotating parts. Switch the power tool on only after
bringing it into position at the workpiece. Touching rotating parts,
especially rotating drill bits or other accessories, may lead to injury.
▶ Dust from materials, such as paint containing lead, some wood species,
concrete / masonry / stone containing silica, and minerals as well as
metal, may be harmful. Contact with or inhalation of the dust may cause

such as oak and beech dust, especially in conjunction with additives for
wood conditioning (chromate, wood preservative). Material containing
asbestos may be handled only by specialists. Use a dust removal
system whenever possible. To achieve a high level of dust collection,
use a suitable vacuum cleaner. When indicated, wear a respirator
appropriate for the type of dust generated. Ensure that the workplace
is well ventilated. Follow national requirements for the materials you
want to work with.

dust that will be produced. Use an industrial vacuum cleaner with
an officially approved protection classification in compliance with
locally applicable dust protection regulations.

Careful handling and use of power tools
▶ Secure the workpiece. Use clamps or a vice to secure the workpiece.
The workpiece is thus held more securely than by hand and both hands
remain free to operate the power tool.
▶ Ensure that the accessory tools used have a mounting system that
is compatible with the electric tool and that they are secured in the
chuck correctly.
▶ In the event of a power failure or interruption in the electric supply,
switch the power tool off, unplug the supply cord and release the
switch lockbutton (if applicable). This will prevent accidental restarting
when the electric power returns.
Electrical safety
▶ Before beginning work, check the working area (e.g. using a metal
detector) to ensure that no concealed electric cables or gas and
water pipes are present. External metal parts of the tool may become
live, for example, when an electric power line is damaged accidentally.
This presents a serious risk of electric shock.
▶ Check the tool's supply cord at regular intervals and have it replaced
by a qualified specialist if found to be damaged. If the tool's supply
