If the magnet is not positioned on a magnetisable plate
or when the magnetic foot is defective, the motor will
not start.
Work only with the absolutely required amount of
feed. Excessive feed can lead to breakage of the appli-
cation tool and loss of the magnetic holding power.
When the power supply is disconnected while the
motor is running, a protective circuit prevents auto-
matic restarting of the motor. Restart the motor again.
Adjust the gear setting only when the machine is at a
complete stop or when the motor is running down.
Do not stop the drill motor during the drilling proce-
dure.
Only remove the core bit from the drilled hole while
the motor is running.
If the core bit should remain stuck in the material, stop
the drill motor and carefully turn the core bit out coun-
ter-clockwise.
Remove the chips and the drilled core after each drilling
process.
Do not touch the chips with your bare hands.
Always use a chip hook (6 42 01 001 00 0).
Danger of burning! The surface of the magnet can
reach high temperatures. Do not touch the mag-
net with your bare hands.
When changing a drill bit, pay attention not to damage
the cutting edges.
When core drilling layered material, remove the core
and the chippings after drilling each layer.
Do not use the magnetic core drill unit when the cool-
ing-lubricant system is defective. Each time before oper-
ating, check for tightness against leaks and for cracks in
the hoses. Prevent liquids from entering or penetrating
electrical components.
In case of improper use, the motor can become dam-
aged.
The magnetic core drill unit is equipped with a temper-
ature switch. When the motor gets too warm, the mag-
netic core drill unit switches off.
When the motor has cooled down, the magnetic core
drill unit can be switched on again.
To reduce the cool-down period, the motor can be
switched on by pressing and holding the ON button. Dur-
ing the cool-down period, the motor will only run while
the ON button is pressed.
PRCD personal protection switch (*)
(see page 10)
The PRCD personal protection switch is specifically for
your protection; therefore, do not misuse it as on
On/Off switch.
If the PRCD personal protection switch is damaged, e.g.
due to contact with water, do not use it any more.
The PRCD personal protection switch is indispensable;
it is used for protection of the power tool operator
against electric shock. Under fault-free operation, the
control lamp of the PRCD personal protection switch
lights up.
Check the operability of the PRCD personal protection
switch before beginning to work:
1. Connect the plug of the PRCD personal protection
switch with the mains socket outlet.
2. Press the RESET–button. The indication light on the
PRCD personal protection switch lights up.
3. Disconnect the plug from the socket outlet. The indi-
cation light goes out.
4. Repeat steps 1. and 2.
5. Press the TEST–button; the indication light goes out.
If the indication light does not go out, do not run the
machine. In this case, contact the customer service.
6. Press the RESET–button; when the indication light
lights up, the machine can now be switched on.
Do not use the PRCD personal protection switch for
switching the power tool on and off.
Repair and customer service.
When working metal under extreme oper-
ating conditions, it is possible for conductive
dust to settle in the interior of the power
tool. The total insulation of the power tool can be
impaired. Blow out the interior of the power tool via
the ventilation slots frequently with dry and oil-free
compressed air.
Renew stickers and warning indications on the power
tool when aged and worn.
After several hours of operation, the play in the dove-
tail guide can increase. As a consequence, the drill
motor can glide alongside the dove-tail guide by itself.
This will lead to a malfunction; when the motor glides
or runs down, the cutter can become damaged. In this
case, retighten all fastening screws of the dove-tail guide
adequately so that the drilling motor can easily be
moved manually, yet does not glide by itself (see
page 18).
Products that have come into contact with asbestos
may not be sent in for repair. Dispose of products con-
taminated with asbestos according to the applicable
country-specific regulations for such disposal.
When the machine's power supply cord is damaged, it
must be replaced by the manufacturer or their repre-
sentative.
