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.
