Original operating instructions

GB
It is recommended to:
Use the drill in a way that it is exactly located between the three clamping jaws of the
quick action chuck.
Clamp the end mill by means of the collet chuck and the corresponding clamping collets.
Clamp the end face mill by means of the end mill arbor.
When drilling, please observe that
It is necessary to set the suitable speed depending on the diameter of the drill,
The press-on must only be as intense that the drill can cut on no-load,
If the press-on is too intense, it might result in early tool wear perhaps even tool fracture
resp. jamming in the drill hole. If the tool gets jammed, immediately stop the main drive
motor by actuating the emergency-stop button,
For hard materials, e.g. steel, it is necessary to use commercial cooling/lubricating
agents,
Generally always back out the tool from the workpiece while the shaft is turning.
ATTENTION!
Do not use the quick action chuck as milling tool. Do not clamp the milling tool in the
quick action chuck in no case. Use a collet chuck and the corresponding collets for
the end mill.
When milling, make sure that
The suitable cutting speed is selected,
For materials with normal mechanical strength, e.g. steel 18-22 m/min,
For materials with higher mechanical strength 10-14 m/min,
The press-on is selected in a way that the cutting speed remains constant,
commercial cooling/lubricating agents are used for hard materials.
1.4
Possible dangers caused by the drilling-milling machine.
The drilling-milling machine was built using the latest technological advances.
Nonetheless there remains a residual risk, since the drilling-milling machine operates with
high revolutions,
rotating parts and tools,
electrical voltage and currents.
We have used construction resources and safety techniques to minimise the health risk to
the staff resulting from these hazards.
If the drilling-milling machine is used and maintained by staff who are not duly qualified,
there may be a risk by the drilling-milling machine resulting from incorrect operation or
unsuitable maintenance.
INFORMATION
All persons involved in assembly, commissioning, operation and maintenance must
be duly qualified,
strictly follow this operating manual.
Disconnect the drilling-milling machine whenever cleaning or maintenance work is being car-
ried out.
