Check the condition
of the substrate
The magnetic holding force is dependent
on the condition of the substrate. The
clamping force is signicantly reduced by
paint, zinc and scale coatings and rust.
The substrate must satisfy the following
conditions in order to achieve su󰀩cient
magnetic holding force:
■The substrate must be magnetic.
■The clamping surface and the magnetic
foot (1) must be clean and grease-free.
■The clamping surface must be com-
pletely smooth and level.
NOTE
►Clean the substrate and the magnetic
foot (1) 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 e󰀨ect 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 work-
pieces with an uneven surface.

Feed unit faults:
In the event of a fault, the feed unit stops
automatically and an "ALARM" (42) error is
indicated.
This occurs, for example, when "Safety
Control" is triggered (see section ““Safety
Control” shutdown”).
Rotating mechanism (MAB 845 V only)
In order to permit optimum alignment even
in di󰀩cult positions, the model MAB 845
V is additionally equipped with a rotating
mechanism. It allows the upper part of the
machine to be rotated by 30° to both sides
and by 20 mm forwards and backwards
with the magnetic foot engaged.
Loosen the locking device of the rotat-
ing mechanism (15).
Position the upper part of the machine
laterally and longitudinally.
Lock the rotating mechanism again.
ATTENTION
►Operate the machine only with the
rotating mechanism locked.

follows:
Push twist drills with MK taper into the
spindle taper (7) of the machine from
below.
Push twist drills with straight shank
into the drill chuck after tting the drill
chuck (see section “Using the drill
chuck”).
Position and x the machine at the
location of use.
Switch on the clamping magnet and
check the magnetic holding force (see
section “Activating/deactivating the
magnetic clamp”).
Select a suitable speed and switch on
the machine.
Make sure that the feed unit is disen-
gaged. The hand lever (12) is in the
extended position (see g. 6).
Direct the drill to the material with the
handle (12).
Alternatively, the "Automatic Feed"
function can be used (see section
“Automatic feed”).
NOTE
Observe the following instructions when
drilling with twist drills:
►Under excessive pressure, the drill
can wear out and the machine can be
overloaded.
►Make sure that swarf is removed
regularly. With larger drilling depths,
break up the swarf.
►Use BDS 6000 cooling lubricant
concentrate.
Drilling with core drills
When drilling with core drills, proceed as
follows:
For core drills with 19 mm Weldon
shaft, mount the MK3/19 mm Weldon
industrial holder.
For core drills with 32 mm Weldon
shaft, mount the MK3/32 mm Weldon
industrial holder.
Connect the cooling lubricant system.
Insert the appropriate ejector pin into
the core drill and insert the core drill
into the tool holder.
Position and x the machine at the
location of use.
Switch on the clamping magnet and
check the magnetic holding force (see
section “Activating/deactivating the
magnetic clamp”).
Select a suitable speed and switch on
the machine.
Make sure that the feed unit is disen-
gaged.
The hand lever (12) is in the extended
