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.
