4.6 Clamping the workpieces
CAUTION!
Injury by parts flying off.
The workpiece always needs to be fixed by a machine vice, a jaw chuck or by another
appropriate clamping tools such as clamping claws.
4.7 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 reduction stage.
H = rapid
L = low
 Adjust the speed with the potenti-
ometer. The speed and thus the
cutting speed are depending on the
material of the workpiece, the mill-
ing cutter diameter and the cutter
type.
