1.4.1 Avoiding misuses
Use of suitable cutting tools.
Adapting the speed adjustment and feed to the material and workpiece.
Clamp workpieces firmly and vibration-free.
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 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.

1.18 Accident report
Inform your superiors and Optimum Maschinen Germany GmbH immediately in the event of
accidents, possible sources of danger and any actions which almost led to an accident (near
misses).
There are many possible causes for "near misses".
The sooner they are notified, the faster the causes can be eliminated.
1.19 Electrical system
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 operator of 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 certain intervals.
The deadlines must be set so that arising, foreseeable defects can be detected in time.
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).
1.20 Inspection deadlines
Define and document the inspection deadlines for the machine in accordance with the Factory
Safety Act and perform an operational risk analysis in accordance with the Work Safety Act.
Also use the inspection intervals in the maintenance section as reference values.

2.10 Emissions
The generation of noise emitted by the drilling machine is 76 dB(A) at idle speed according DIN
ISO 8525.
If the drilling machine is installed in an area where various machines are in operation the acou-
stic influence (immission) on the operator of the radial drilling machine may exceed 80 dB(A).
INFORMATION
This numerical value was measured on a new machine under proper operating conditions.
Depending on the age respectively on the wear of the machine it is possible that the noise
behaviour of the machine changes.
Furthermore, the factor of the noise emission is also depending on manufacturing influencing
factors, e.g. speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is the emission level and 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 the proximity and the period of time during which the ope-
rator 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.
