If an extension cord is needed, it must be a three-
core lead with a protective (earth) contactor that is
properly connected to both the plug and the
coupler of the cord.
When working outdoors, only use the correspond-
ingly marked extension cable approved for this
purpose.
Regularly check extension cables and replace if
damaged.
Extension cables must be suitable for the driving
unit and magnetic drill stand power ratings (see
Technical Specifications). If using a roll of cable,
always roll up the cable completely.

Attaching the Securing Strap

For drilling work carried out on angled and
vertical surfaces and overhead, the magnetic
drill must be secured with the securing strap (1)
supplied to prevent it from falling if the power
supply is interrupted.
Fit the securing strap (1) so that the magnetic
drill stand is moved away from the operator if
the mains voltage fails.
Replace the securing strap (1) if it has had to
catch a falling magnetic drill stand.
Caution! Check the securing strap (1) for
damage. Before using the securing strap (1),
always check it carefully to ensure it is operating
faultlessly and as specified. If the securing strap
(1) is damaged or if the ratchet (2) is no longer
working properly, replace the securing strap
immediately.
- Fit the securing strap (1) on one of the two
holding points (3) of the magnetic drill stand.
- Then secure the securing strap to another suit-
able fastening point or to the material being
processed.
(a)
- Notes on the securing strap (1):
Insert the free end of the securing strap (1) from
below through the opening in the ratchet shaft
and then tension the free end of the securing
strap until it is loosely fitted.
The strap must not be tightly fitted: you
must be able to unroll the securing strap
by more than one rotation about the ratchet
shaft - This is essential to ensure secure
fastening. Tension the securing strap with a
pumping action on the ratchet lever (a).

To loosen the securing strap:
Caution: the tension is released in sudden
bursts! To loosen the securing strap, open
the ratchet fully and simultaneously use your
finger to pull the locking strap (b) upward.
- Ensure that the securing strap is guided to be
taut in position.
- Check that the strap connection is secure.
The securing strap does not replace the
magnetic force of the magnetic drill stand: it
is simply used to secure against falling in the event
of a voltage failure.
7.2 Cooling Unit for Core Drilling
The tool life depends on the lubrication. Lubri-
cating the inside of the core drill bit with high-
performance cutting oils is essential for core
drilling.
To fill with oil, remove the container (5) from
the magnetic drill stand.
Fill the container with high-performance cutting oil
(5) and close the screw cap. Switch the lubrication
on or off at the supply cock (6).
For work carried out on vertical and overhanging
surfaces or overhead surfaces, the container (5)
must be emptied or removed to prevent liquid
from escaping (otherwise there is a risk of cutting
oil entering the motor and causing a short-circuit).
When carrying out this type of task, spray the
inside of the cutting edge tool before drilling with
universal cutting spray (see chapter 10 Accesso-
ries). Repeat the process several times for larger
drilling depths.
7.3 Adjusting the Gear, Speed and Direc-
tion of Rotation (only applies to MAG
50)
Two-speed gear box:
Do not activate the thumbwheel (8) until the
motor has completely stopped.
Select the required gear by turning the thum-
bwheel (8). If necessary, you can aid the switching
procedure by turning the drill spindle slightly.
Recommended setting:
• • = 2nd gear, high speed: Drilling in steel with a
bit diameter of up to approx. 26 mm
• = 1st gear, high torque: Drilling in steel with a
bit diameter larger than approx. 26 mm
Setting speed
Using the setting wheel, you can adjust the motor
speed continuously (12) and thus adapt it to the
material and working conditions.
