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 98 160 40 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.
PRCD personal protection switch (*) (see page 7)
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 red.
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 red.
3. Disconnect the plug from the socket outlet. The red
indication light goes out.
4. Repeat steps 1. and 2.
5. Press the TEST–button; the red indication light goes
out. If the red 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 red, 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 sleeve
guide can increase. As a result, the sleeve can slide by
itself along the guide. In this case, tighten the set screw
of the guide accordingly, so that the sleeve can easily be
moved manually, yet does not slide by itself (see page
12).
Flush the cooling-lubricant system with water, clean
and drain it completely when not using the machine for
periods longer than two weeks.
For continuous operation, the cooling-lubricant system
must be flushed with water and cleaned approx. every
4 weeks.
When the machine's power supply cord is damaged, it
must be replaced by the manufacturer or their repre-
sentative.
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.
