mable materials or that not constitute a health hazard using a rotating filing-stripping tool that
has a number of grooves for collecting the filings.
The drilling machine may only be operated with tools whose cutting edge arrangement forms a
force couple around the rotational axis in engagement.
A quick-action drill chuck for holding the tools is provided as standard. The drilling machine
must only be used with a quick-action drill chuck.
Operations
not in accord-
ance with
intended use!
If the drilling machine is used in any way other than described above, modified without the
approval of the company Optimum Maschinen Germany GmbH then the drilling machine is
being used improperly.
We will not be held liable for any damages resulting from any operation which is not in accord-
ance with the intended use.
We expressly point out that the guarantee or CE conformity will expire due to any constructive
technical or procedural changes which had not been performed by the company Optimum
Maschinen Germany GmbH.
It is also part of intended use that you
observe the limits of the drilling machine,  "Technical data“ on page 19
the operating manual is observed,
inspection and maintenance instructions are observed.

emitted interferences.
ATTENTION!
If the drilling machine is not used as intended or if the safety directives or the operating
instructions are ignored the liability of the manufacturer for any damages to persons or
objects resulting hereof is excluded and the claim under guarantee is becoming null and
avoid!
1.3 Reasonably foreseeable misuse
Any other use as the one determined under the "Intended use" or any use beyond the
described use shall be deemed as not in conformity and is forbidden.
Any other use has to be discussed with the manufacturer.
It is only allowed to process metal, cold and non-inflammable materials with the drilling
machine.
In order to avoid misuses it is necessary to read and understand the operating instructions
before the first commissioning.
The operating staff has to be qualified.
1.3.1 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.
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.
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.

1.4 Possible dangers caused by the drilling machine
The drilling machine has undergone a safety inspection (analysis of danger with assessment of
risks). It has been designed and built on the basis of this analysis using the latest technological
advances.
Nevertheless, there is a residual risk as the drilling machine operates with
at high speeds,
rotating parts,
with electrical voltages and currents.
We have used construction resources and safety techniques to minimize the health risk for the
staff resulting from these hazards.
If the drilling machine is used and maintained by the staff who are not duly qualified, there may
be a risk resulting from incorrect or unsuitable maintenance of the drilling machine.
INFORMATION
All staff involved in assembly, commissioning, operation and maintenance, must
be duly qualified,
strictly follow these operating instructions.
In the event of intended use
there may be a risk to the staff,
there may be a risk to the machine and other material values,
the correct function of the drilling machine may be affected.
Disconnect the drilling machine whenever cleaning or maintenance work is being carried out.
WARNING!
The drilling machine may only be used with functional safety devices.
Disconnect the drilling machine immediately, whenever you detect a failure in the safety
devices or when they are not fitted!  "Safety devices“ on page 13
All additional devices installed by the operator have to be equipped with the prescribed
safety devices.
This is your responsibility being the operating company!
1.5 Qualification of the staff
1.5.1 Target group
This manual is addressed to
the operating companies,
the operators,
the staff for maintenance works.
Therefore, the warning notes refer to both, operation and maintenance staff of the drilling
machine.
Determine clearly and explicitly who will be responsible for the different activities on the
machine (operation, maintenance and repair).
Unclear responsibilities constitute a safety risk!
Always disconnect plug of the drilling machine from the electrical power supply. This will pre-
vent it from being used by unauthorized staff.
Operator
The operator is instructed by the operating company about the assigned tasks and possible
risks in case of improper behaviour. Any tasks which need to be performed beyond the opera-

2.18 Emissions
The emission of the drilling machine is 73 dB(A) at idle.
If the is installed in an area where various machines are in operation the acoustic influence
immission) on the operator of the drilling machine may exceed 85 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 op-
erator 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 shall allow the operator of the machine to more eas-
ily evaluate the endangering and risks.
CAUTION!
Depending on the overall noise exposure and the basic limit values the machine
operators has to wear an appropriate hearing protection.
