1.4 Reasonably foreseeable misuse
Any use other than that specified under "Intended use" or any use beyond that described will be
deemed non-intended use and is not permissible.
Any other use must be discussed with the manufacturer.
It is only allowed to process metal, cold and non-inflammable materials with the drilling- milling
machine.
In order to avoid misuse, it is necessary to read and understand the operating instructions
before first commissioning.
Operators must be qualified.
1.4.1 Avoiding misuse
Use of suitable cutting tools.
Adapting the speed setting and feed to the material and workpiece.
Clamp workpieces firmly and free of vibration.
ATTENTION!
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.
WARNING!
Risk of injury caused by flying workpieces.
Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in
the machine vice and that the machine vice is firmly clamped onto 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.
Set the bearing clearance and guides correctly.
Recommendations:
Insert the drill in a way that it is positioned exactly between the three clamping jaws of the
drill chuck.
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,
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,
For hard materials, e.g. steel, it is necessary to use commercial cooling/lubricating
agents.Basically, always pull out the drill with rotating spindle from the workpiece.
1.5 Possible dangers posed 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,
rotating parts,
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 its incorrect or unsuitable maintenance.

misses).
There are many possible causes for "near misses".
The sooner they are notified, the quicker the causes can be eliminated.
1.16 Electronics
Have the machine and/or the electric equipment checked regularly. Immediately eliminate all
defects such as loose connections, defective wires, etc.
A second person must be present during work on live components to disconnect the power in
the event of an emergency. Disconnect the machine immediately if there is a malfunction in the
power supply!
Comply with the required inspection intervals in accordance with the factory safety directive,
operating equipment inspection DGUV, formerly BVG.
The operating company responsible for the machine must ensure that the electrical systems
and operating equipment are inspected with regards to their proper condition, namely,
by a qualified electrician or under the supervision and direction of a qualified electrician,
prior to initial commissioning and after modifications or repairs, prior to recommissioning
and at set intervals.
The intervals must be set so that foreseeable defects can be detected in a timely manner, when
they occur.
The relevant electro-technical rules must be followed during the inspection.
The inspection prior to initial commissioning is not required if the operator receives confirma-
tion from the manufacturer or installer that the electrical systems and operating equipment com-
ply with the accident prevention regulations, see conformity declaration.
Permanently installed electrical systems and operating equipment are considered constantly
monitored if they are continually serviced by qualified electricians and inspected by means of
measurements in the scope of operation (e.g. monitoring the insulation resistance).

2.11 Emissions
The noise emission of the drilling milling machine is 76 to 78 dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.
Furthermore, the noise emission also depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
The specified numerical value represents the emission level and does not necessarily a safe
working level.
Though there is a dependency between the degree of the noise emission and the degree of the
noise disturbance it is not possible to use it reliably to determine if further precaution measures
are required or not.
The following factors influence the actual degree of the noise exposure of the operator:
- Characteristics of the working area, e.g. size or damping behaviour,
- other noise sources, e.g. the number of machines,
- other processes taking place in proximity and the period of time, during which the opera-
tor is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations.
This information about the noise emission should, however, allow the operator of the machine
to more easily evaluate the hazards and risks.
2.6 Work area
Keep a work area of at least one metre around the machine
free for operation and maintenance.
