Safety
Commission the drilling-milling machine only under the following conditions:
The drilling-milling machine is in proper working order.
The drilling-milling machine is used as intended.
The operating manual is followed.
All safety devices are installed and activated.
All failures should be eliminated immediately. Stop the drilling-milling machine immediately in
the event of any abnormality in operation and make sure it cannot be started up accidentally or
without authorisation.

4.13
Use of collet chucks
When using collet chucks for the reception of milling tools, a higher operation tolerance can be
achieved. The exchange of the collet chucks for a smaller or larger end mill cutter is performed
simply and rapidly and it is not necessary to disassemble the complete tool. The collet chuck is
pressed into the ring of the swivel nut and must rest there by itself. The milling cutter is clamped
by fastening the swivel nut on the tool.
Make sure that the correct collet chuck is used for each milling cutter diameter, so that the mill-
ing cutter may be fastened securely and firmly.

Clamping the workpieces
CAUTION!
Injury by flying off parts.
The workpiece is always to be fixed by a machine vice, jaw chuck or by another
appropriate clamping tool such as for the clamping claws.
4.15
Changing the speed range
ATTENTION!
Wait until the drilling-milling machine has come to a complete halt before changing the
speed using the gear switch.
Select gear level
H = rapid (590 min-1 - 3100 min-1)
M = middle (270 min-1 - 1400 min-1)
L = low (115 min-1 - 600 min-1)
Adjust the speed with the potentiome-
ter. The speed and thus the cutting
speed depends on the material of the
workpiece, the milling cutter diameter
and the cutter type.
