Setting the direction of rotation
Set the required direction of rotation at the switch
(19).
R = Clockwise (adjust for drilling)
L = Counter-clockwise
7.4 Switching on/Switch-on Sequence
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 (18) to
"I". When the magnet is switched on, the indi-
cator lamp built into the switch (18) lights up.
2. Wait until this occurs before turning on the
driving unit at the switch (16).
See also chapter 9.
Note: The full holding power of the magnet is avail-
able when the driving unit is switched on.
7.5 Switching off the Driving Unit
Press switch (17). Wait until the driving unit has
come to a complete standstill.
7.6 Switching off the Magnet
When the magnet is switched off, the magnet
loses its holding power.
Set switch (18) to "0".
7.7 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
irregularities must be smoothened. Clean the
magnet block as well (20) 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.
7.8 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 (17). Remove the
tool from the borehole.
General notes:
- Centre the position at which the hole is to be
drilled.
- Align the magnetic drill stand so that the drill bit
is above the centre marking.
- Switch on the magnet of the magnetic drill stand
(set switch (18) to "I".).
- Then switch on the driving unit (press switch
(16)).
- If necessary, switch on the cooling lubrication
unit (see chapter 7.2.
- Start the drilling operation with minimum feeding
force. When the drill bit has started to drill,
slightly higher feeding force can be applied.
Excessive feeding force leads to premature wear
of the drill bit. Ensure that the chip flow is regular
- Use a wire hook to remove the chips.
- If the bored piece of metal is not automatically
ejected from the core drill, remove it using a tool,
e.g. with the wire hook.
If (after use) the magnetic drill stand is placed
on a material with low heat-dissipation char-
acteristics for a long period (e.g. plastic), the
magnet must not be switched on because this
could lead to overheating of the magnetic coils.
Special notes for tools with morse taper shank
MK2 (only applies to MAG 50):
Inserting tool:
The tool is only guaranteed to fit perfectly in
the drill spindle (11) if the female taper of the
drill spindle and the taper shank of the tool are free
of dirt and grease.
Caution! Never use excessive force to press
tools into the female taper of the drill spindle!
