if there is too much pressure, the drill will wear quickly and may even break or jam in the
borehole. If the drill gets jammed immediately stop the main motor by pressing the emer-
gency stop button,
use commercial cooling/lubricating agents for hard materials, e.g. steel and
generally always back the spindle out of the workpiece while it is still turning.
ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into a quick
action drill chuck. Use a collet chuck and appropriate collets for end mills.
When milling, ensure that
the right 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 so that the cutting speed remains constant,
normal trade coolants/lubricants are used for hard materials.

Possible dangers caused by the drilling- milling machine
The drilling- milling machine was built using state-of-the-art technology.
Nevertheless, there is a residual risk as the drilling- milling machine operates with
high speeds,
circulating parts and tools and
electrical voltage and currents.
We have used design and safety engineering to minimize the health risk to personnel 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.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,
and strictly follow these operating instructions.
Always disconnect the drilling- milling machine from the electrical power supply before perform-
ing cleaning or maintenance tasks.
WARNING!
The drilling- milling machine may only be operated with functional safety devices.
Disconnect the drilling- milling machine immediately, whenever you detect a failure in
the safety devices or when they are not fitted!
All additional devices installed by the operator must be equipped with the stipulated
safety devices.
This is your responsibility as the operator!
