 Firmly tighten the auxiliary handle, hold the machine
firmly with both hands while working and keep
proper footing and balance at all times. The machine
is guided more secure with both hands.
 Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than
by hand.
 Keep your workplace clean. Blends of materials are
particularly dangerous. Dust from light alloys can burn
or explode.
 For drilling without impact in wood, metal, ceramic
and plastic as well as for screwdriving, tools without
SDS-plus are used (e.g., drills with cylindrical shank).
For these tools, a keyless chuck or a key type drill
chuck are required.
 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 inserting 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 respiratory infections and/or
cancer. Materials containing asbestos may only be
worked by specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-ing place.
– It is recommended to wear a P2 filter-class

 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.
