The quick-clamping nut 15 may only be used for cutting
discs.
Use only a flawless, undamaged quick-clamping nut 15.

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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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
materials to be worked.
Prevent dust accumulation at the workplace. Dust can
easily ignite.
Operation
Hold the power tool by the insulated gripping surfaces
23 and by the auxiliary handle 8 when performing an
operation where the application tool may contact hid-
den wiring. An application tool contacting a "live" wire
may make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Starting Operation
Inserting the battery
Insert the charged battery 5 from above into the base of the
power tool until the battery is securely locked.
