The quick change chuck is automatically locked. Check the
locking effect by pulling the quick change chuck.
Inserting SDS-plus Drilling Tools: Check the latching by
pulling the tool.
Replace a damaged dust protection cap immediately.
The dust protection cap largely prevents the penetration of
drilling dust into the tool holder during operation. When in-
serting the tool, pay attention that the dust protection cap
is not damaged.
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health and cause allergic reactions, lead to respi-
ratory infections and/or cancer. Materials containing as-
bestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble for the material.
– 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. Dusts can
easily ignite.
If the application tool should become blocked, switch
the machine off. Loosen the application tool.
Before switching on the power tool, make sure that the
application tool moves freely. When switching on with a
blocked drilling tool, high torque reaction can occur.
Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.
