Cleaning & Maintenance; Troubleshooting - Metabo MAG 32 Operating Instructions Manual

teristics 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:
To prevent the driving unit from moving up/
down accidentally: pull out the lock switch (8).
The tool is only guaranteed to fit perfectly in
the drill spindle (12) 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!
Always use sharp tools in perfect condition.
Switch off the machine. Pull the mains plug
from the socket. Caution! When you unplug
the mains plug, the magnet loses its holding power.
Tools with a taper shank MK2 can be used directly
in the female taper of the drill spindle (12).
Driving out the tool:
Insert the removal tool (11) - with the sloping edge
against the tool - in the slot (10) on the machine
neck. If the removal tool cannot be inserted through
the drill spindle, you should turn the drill spindle (12)
slightly by hand. Drive out the tool by knocking
lightly on the removal tool with a hammer. (11)
Special notes on tools with Weldon shank 19
mm:
For MAG 50: First insert the industrial attachment
6.26602 (see chapter 9. Accessories).
To prevent the driving unit from moving up/
down accidentally: pull out the lock switch (8).
When inserting the attachment, ensure that
the side pin of the industrial attachment
engages with the anti-twist device (27).
Then connect the hose from the cooling lubrication
unit to the connecting piece on the industrial attach-
ment 6.26602.
Inserting the tool:
- Insert the centring pin (of an appropriate length)
into the tool.
- Insert the tool in the tool holder (26) so that both
surfaces (on the cylindrical part of the tool) are
located at the positions of the threaded pins (25).
- Guide the tool upwards as far as it will go (against
the pressure of the integral spring) and tighten the
threaded pins (25) using the Allen key.
Removing the tool:
- Release the two threaded pins (25).
7. Cleaning, Maintenance
Perform regular maintenance work, cleaning and
lubrication.
Remove the mains plug from the socket before
carrying out any settings, maintenance or repairs.
Caution! When you unplug the mains plug, the
magnet loses its holding power.
For lubricating the rack and pinion that moves the
slide plate (16) up and down, a few drops of oil
should be applied occasionally to the rack.
Coat the sliding surfaces of the slide plate (16) with
multi-purpose grease.
Backlash of the slide plate
The backlash of the side plate is set ex works.
The side plate (16) must be adjusted so that it can
still be moved freely up and down (when the driving
unit is installed), and so that it will remain in any
position without the weight of the driving unit pulling
it down.
If necessary, you can adjust the backlash of the
slide plate (16) using the three threaded pins (9):
release the counternuts, tighten the threaded pins
and fasten the counternuts again.

8. Troubleshooting

Electronic restart protection (for preventing
accidental restarting)
If, when the driving unit is switched on,
a) the magnet is switched off or
b) the power supply is interrupted,
the driving unit comes to a standstill.
If the magnet is then reactivated or the power supply
restored, the driving unit will not restart automati-
cally for safety reasons (electronic restart protec-
tion). Switch the driving unit back on.

Electronic signal indicator (14) for MAG 50
Continuously lit - Overload
The motor temperature is too high. Reduce the load
on the machine. The machine will stop if the over-
loading persists. Switch off the machine, switch it
back on again and allow to cool down at idle speed.
The motor part cannot be moved up or down.
