WARNING!
Risk of injury caused by workpieces flying off.
Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in the
machine vice resp. that the machine vice is firmly clamped on the machine table.
Use cooling and lubricating agents to increase the durability of the tool and to improve the
surface quality.
Clamp the cutting tools and workpieces on clean clamping surfaces.
Sufficiently lubricate the machine.
Correctly adjust the bearing clearance and the guidings.
It is recommended:
Insert the drill in a way that it is exactly positioned between the three clamping jaws of the
quick action chuck.
Clamp and mills by means of the collet chuck and the corresponding collets.
Clamp end face mills by means of shell end mill arbors.
When drilling make sure that
the suitable speed is set depending on the diameter of the drill,
the pressure must only be such that the drill can cut without load
in case of too strong pressure the drill will get worn early or even might break resp. get
jammed in the hole. If the drill gets jammed immediately stop the main motor by pressing
the emergency stop button,
for hard materials, e.g. steel, use commercial cooling / lubricating agents,
generally always drive the turning spindle out of the workpiece.
ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into
the quick action drill chuck. Use a collet chuck and the corresponding collets for the end
mill.
When milling make sure that
the corresponding cutting speed is selected,
for workpieces with normal strength values, e.g. steel 18-22 m/min,
for workpieces with high strength values 10-14 m/min,
the pressure is selected in a way that the cutting speed remains constant,
for hard materials commercial cooling / lubricating agents are used.

Possible dangers caused by the drilling-milling machine
The drilling-milling machine is state-of-the-art.
Nevertheless, there is a residual risk as the drilling-milling machine operates with
at high speeds,
with rotating parts and tools,
with electrical voltages and currents.
We have used construction resources and safety techniques to minimize the health risk to per-
sons resulting from these hazards.
If the drilling-milling machine is used and maintained by personnel who are not duly
qualified, there may be a risk resulting from incorrect or unsuitable maintenance of the drilling-
milling machine.
