WARNING!
In the event of improper use, the mill drill
there may be a risk to the staff,
the mill drill and other material property of the operating company will be endan-
gered,
the correct function of the mill drill may be affected.
The mill drill is designed and manufactured to be used for milling and drilling cold metals or
other non-flammable materials or materials that do not constitute a health hazard by using com-
mercial milling and drilling tools.
The mill drill must only be installed and operated in a dry and well-ventilated place. If the mill
drill is used in any way other than described above, modified without the approval of the com-
pany Optimum Maschinen Germany GmbH then the mill drill 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 would like to stress that any modifications to the construction or technical or technological
modifications that have not been authorised by the company Optimum Maschinen Germany
GmbH will also render the guarantee null and void. It is also part of proper use that

1.4 Reasonably foreseeable misuses
Any other use as the one determined under the "proper 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 milling-
machine.
In order to avoid misuses it is necessary to read and understand the operating instructions
before the first commissioning.
The operators must be qualified.
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.

OPTIMUM
MASCHINEN - GERMANY

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.
Clamp and mills by means of the collet chuck and the corresponding collets.
Clamp end face mills by means of shell end mill arbors.
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.
ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into
the quick action drill chuck. Use a collet chuck and the corresponding collets for the end
mill.
When milling make sure that
the corresponding 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 in a way that the cutting speed remains constant,
for hard materials commercial cooling / lubricating agents are used.
1.5 Possible dangers caused by the mill drill
The mill drill was built using the latest technological advances.
Nonetheless there remains a residual risk, since the mill drill operates with

2.11 Emissions
The emission of the mill drill is below 80 dB(A).
If the mill drill is installed in an area where various machines are in operation, the noise expo-
sure (immission) on the operator of the mill drill at the working place may exceed 80dB(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 oper-
ator is exposed to the noise.
Consult OSHA, state and local regulations in order to determine compliance, dangers and risks
to the operator.
CAUTION!
Depending on the overall noise exposure and the basic limit values the machine
operators must wear an appropriate hearing protection.
We generally recommend to use a noise protection and a hearing protection.
