Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Prevent dust accumulation at the workplace. Dust can
easily ignite.

Working Advice
Exercise caution when cutting slots in structural walls;
When cutting lightweight materials, take into account
Clamp the workpiece if it does not remain stationary due
Do not strain the machine so heavily that it comes to a
After heavily straining the power tool, continue to run it
Do not touch grinding and cutting discs before they have
Do not use the power tool with a cut-off stand.
When the power tool is electrostatically charged, the built-in
electronic control switches it off. To restart the power tool,
press the On/Off switch 3 again.
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when setting the ma-
chine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
must be mounted properly and be able to move freely.
Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grinding
tools. Damaged grinding tools can burst and cause injuries.
The power tool will continue to work as soon as the blockage
is rectified.
