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.
▶ Before beginning the work, check the hazard classification of the
dust that will be produced. Use an industrial vacuum cleaner with
an officially approved protection classification in compliance with
locally applicable dust protection regulations.
▶ Working on the material may cause it to splinter. Wear eye protection.
Flying fragments present a risk of injury to the body and eyes.
▶ Always hold the tool securely by the grip. If the accessory tool (e.g.
the drill bit) sticks and stalls, the power tool, due to its high torque, may
tend to rotate about its own axis in the direction opposite to that of the
accessory tool.
Use and care of electric tools
▶ Secure the workpiece. Use clamps or a vice to hold the workpiece
in position. The workpiece is thus held more securely than by hand and
both hands remain free to operate the power tool.
▶ Check that the accessory tools used are compatible with the chuck
system and that they are secured in the chuck correctly.
Use and care of battery-powered tools
▶ Check that the tool is switched off before inserting the battery.
Inserting a battery into an electric tool that is switched on can lead to
accidents.
▶ Do not expose batteries to high temperatures and keep them away
from fire. There is a risk of explosion.
▶ Do not disassemble, squash or incinerate batteries and do not subject
them to temperatures over 80°C. This presents a risk of fire, explosion
or injury through contact with caustic substances.
▶ Avoid ingress of moisture. Ingress of moisture may cause a short circuit,
resulting in burning injuries or fire.
▶ Observe the special guidelines applicable to the transport, storage
and use of Li-ion batteries.
▶ Avoid short circuiting the battery terminals. Check that the battery
terminals and the terminals in the power tool are free from foreign
objects before inserting the battery in the tool. Short circuiting the
battery terminals presents a risk of fire, explosion and chemical burns.
Certain kinds of dust are classified as carcinogenic
