The mill drill is in proper working order.
The mill drill is used as intended.
The operating manual is followed.
All safety devices are installed and activated.
All failures should be eliminated immediately. Stop the mill drill immediately in the event of any
abnormality in operation and make sure it cannot be started up accidentally or without authori-
sation.

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 mill drill has come to a complete halt before changing the speed using the
gear switch.
Select gear level
H = rapid ( 708 - 3100 RPM )
M = middle ( 324 - 1680 RPM )
L = low ( 115 - 720 RPM )
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.
