Check the condition
of the substrate
The magnetic clamping force is dependent
on the condition of the substrate. The clamp-
ing force is signicantly reduced by paint,
zinc and scale coatings and rust.
The substrate must satisfy the following con
-
ditions in order to achieve sufcient magnetic
clamping force:
■ The substrate must be magnetic.
■ The clamping surface and the magnetic
foot (8) must be clean and grease-free.
■ The clamping surface must be complete
-
ly smooth and level.
NOTE
► Clean the substrate and the magnetic
foot (8) of the machine before use.
► Remove any unevenness and loose
rust from the substrate.
► The BDS range of accessories in
-
cludes special holding devices.
The best clamping effect is obtained on low-
carbon steel substrate with a thickness of at
least 20 mm.
Steel with low thickness
When drilling into low thickness steel, an
additional steel plate (minimum dimensions
100 x 200 x 20 mm) must be placed under
the workpiece. Secure the steel plate to
prevent it from falling.
NF metals or workpieces with an uneven
surface
A special holding device must be used when
drilling into NF metals or into workpieces with
an uneven surface.
NOTE
► BDS offers a range of accessories with
special clamping devices for tubes and
non-magnetic materials.
Inserting the tool
WARNING
Risk of injury
► Do not use damaged, soiled or worn
tools.
► Change tools only when the machine
is switched off and at a standstill. Pull
the plug out of the mains socket.
► After inserting, check that the tool is
engaged securely.
► Only use tools, adapter and accesso
-
ries that match the machine.
