The extension cable must be suitable for the drill
and magnetic drill stand power ratings (see Tech-
nical Specifications). If using a roll of cable, always
roll up the cable completely.

7.1

Installing safety chain

When working on angled and vertical
surfaces and overhead, the magnetic drill
stand must be secured with the supplied safety
chain (2) so that is cannot fall down if the power
supply is interrupted.
Fit the safety chain (2) so that if the mains
voltage fails the magnetic drill stand is
moved away from the operator.
Caution! Check the safety chain (2) for
damage. Before using the safety chain (2),
always check it carefully to ensure it is operating
faultlessly and as specified. If the safety chain (2)
is damaged or the snap hook (1) is no longer in
perfect working order, replace the safety chain
immediately.
- Fit the safety chain (2) on one of the two holding
points (3) of the magnetic drill stand.
- Then secure the safety chain to another suitable
fastening point or to the material being proc-
essed. Hook the snap hook (1) of the safety chain
into one of the chain links so that the chain is as
taut as possible.
- Check that the snap hook (1) is completely
closed.
The safety chain does not substitute the
magnetic force of the magnetic drill stand,
but is simply used to secure against falling in the
event of a voltage failure.
7.2

Switching on / switch-on sequence

For safety reasons, the drill can only be
switched on after the magnet has been
switched on. Please observe the switch-on
sequence.
1. First switch on the magnet: set switch (11) to
"1". When the magnet is switched on, the indi-
cator lamp built into the switch (11) lights up.
2. Wait until this occurs before turning on the drill
at the switch (9).
See also chapter 9.
Note: The full holding power of the magnet is avail-
able when the drill is switched on.
7.3

Switching off drill

Press switch (10). Wait until the drill has come to a
complete standstill.
7.4

Switching off magnet

When the magnet is switched off, the magnet
loses its holding power.
Set switch (11) to "0".
7.5

Mounting on the workpiece

To permit the magnetic drill stand to adhere prop-
erly to material that is to be drilled, the surface
must be clean and smooth. Loose rust, dirt or
grease must be removed before mounting the
magnetic drill stand; any welding beads or surface
irregularities must be smoothened. Thin coats of
paint will not impair adhesion. Clean the magnet
block as well (12) if necessary.
After switching the magnet on, hold the handle of
the magnetic drill stand and shake it firmly to
ensure that the unit is adhering properly. If it is not,
then check the condition of the surface of the
material and that of the bottom of the magnet
block. Clean as necessary and try again.
Use on thin steel
The unit adheres best to low-carbon steel that is at
least 12 mm thick.
For drilling a hole into thin steel, a steel plate meas-
uring at least 100 x 200 x 12 mm can be secured
under the material at the place where the magnetic
stand is to be positioned.
Non-ferrous metals
To drill a hole in non-ferrous metal, the steel plate
should be secured on the surface of the material
and the magnetic drill stand then placed on the
steel plate.
Round or cambered surfaces
If you need to drill into a round or cambered
surface, then the magnet block (12) should be
positioned with its longitudinal axis parallel to the
axis of the camber.
The open space between the magnet block and
the camber should be packed with steel wedges or
rods on both sides along the entire length of the
magnet block so that after switching on the
magnet as many as possible magnetic lines of
force are conducted from the magnet pole through
the wedges (or rods) and the material to the
magnet block housing.
Ensure that the steel wedges (rods) on both sides
of the magnet block are distributed such that the
axis of the drill bit is aligned directly to the centre
of curvature; otherwise it could be diverted to one
side.
By shaking the handle of the magnetic drill stand,
make sure that the stand adheres properly to the
material.
