►
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 securely guided with both hands.
►
Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than
by hand.
►
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.
► 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 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.
– As far as possible, use a dust extraction system
suitable 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.
