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.
6.2 Cooling Lubrication Unit for Core Drilling
The tool life depends on the lubrication. Lubricating
the inside of the core drill bit with high-performance
cutting oils is essential for core drilling.
To fill with oil, remove the container (6) from
the magnetic drill stand.
Fill the container with high-performance cutting oil
(6) and close the screw cap. Switch the lubrication
on or off at the supply cock (7).
For work carried out on vertical and overhanging
surfaces or overhead surfaces, the container (6)
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 9. Accessories). Repeat
the process several times for larger drilling depths.
6.3 Set gear and rotational speed
(MAG 50 only)
Two-speed gear box:
Do not activate the thumbwheel (15) until the
motor has completely stopped.
Select the required gear by turning the thumbwheel
(15). If necessary, you can aid the switching proce-
dure 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 (13) and thus adapt it to the
material and working conditions.
6.4 Switching on/Switch-on Sequence, direc-
tion of rotation
For safety reasons, the driving unit 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 (19) to "I".
When the magnet is switched on, the indicator
lamp built into the switch (19) lights up.
2. Only then should the driving unit be switched on:
Switch (20) = clockwise (for drilling)
Switch (22) = counter-clockwise, MAG 50 only
See also chapter 8.

Note: The full holding power of the magnet is avail-
able when the driving unit is switched on.
6.5 Switching off the Driving Unit
Press switch (21). Wait until the driving unit has
come to a complete standstill.
6.6 Switching off magnet
When the magnet is switched off, the magnet
loses its holding power.
Set switch (19) to "0".
6.7 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 irregulari-
ties must be smoothened. Clean the magnet block
as well (23) if necessary.
After switching on the magnet, shake the handle (4)
of the magnetic drill stand firmly to ensure that it is
adhering perfectly to the material. 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.
6.8 Drilling
Disconnect the mains plug from the plug
socket before performing any adjustments or
maintenance on the machine. Caution! When you
unplug the mains plug, the magnet loses its holding
power.
Do not use deformed or damaged tools.
Before use, always check tools such as core
drills for deformities or damage.
Do not use accessories that have not been
specified or recommended by Metabo for this
machine. The ability to attach the accessory to your
machine does not guarantee safe operation.
Securing or positioning a tool incorrectly can
cause hazardous situations due to parts
breaking or being blown off.
If a tool is blocked, switch off the driving unit
immediately: Press switch (21). Remove the
tool from the borehole.
General notes:
- Attach guard plate (24).
- Centre the position at which the hole is to be
drilled.
