1.3 Intended use
WARNING!
Improper use of the lathe will result in
will endanger personnel,
will endanger the lathe and other material property of the operator,
the correct function of the lathe may be affected.
The lathe was constructed for the longitudinal and face turning of round or regularly shaped
workpieces of cold metal with a diameter and weight within the limits of the specified technical
data. The lathe must only be installed and operated in a dry and ventilated place. The machine
integrated coolant system is only intended for water-miscible cooling lubricants.
The lathe is designed and manufactured to be used in environments where there is no poten-
tial danger of explosion.
If the lathe is used in any way other than described above, or modified without the approval of
Maschinen Germany GmbH, then the lathe 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 will expire, if any constructive, technical or proce-
dural changes are not performed by the company Optimum Maschinen Germany GmbH.
It is also part of the intended use that you
observe the limits of the lathe,
observe the operating instructions,
and comply with the inspection and maintenance instructions.
 "Technical specification“ on page 20
In order to achieve optimum cutting performance, it is essential to choose the right turning tool,
feed, tool pressure, cutting speed and coolant.

It is forbidden to make any modifications or alternations to the operation values of the
lathe. They could endanger the personnel and cause damage to the lathe.
1.4 Reasonably foreseeable misuses
Any other use other than that specified under "Intended use" or any use beyond the described
use shall be deemed as non-intended use and is not permissible.
Any other use has to be discussed with the manufacturer.
The lathe must not be used to process metal, cold and non-inflammable materials.
In order to avoid misuse, it is necessary to read and understand the operating instructions
before the first commissioning.
The operators must be qualified.
1.4.1 Avoiding misuse
Use of suitable cutting tools.
The operating speed of the lathe may not exceed the permissible speed of the used clamp-
ing device.
Adapting the speed adjustment and feed to the material and workpiece.
Insert the workpiece tightly, without vibration and without one-sided imbalances.
The machine is not designed for the use of hand tools (e.g. emery cloth or files). It is forbid-
den to use any hand tools on this machine.
The machine is not designed to allow long parts to protrude beyond the spindle hole. If
longer parts have to protrude beyond the spindle hole, an additional operator-side, perma-
nent device must be mounted, which completely covers the protruding part and provides
complete protection against spinning parts.
Long workpieces must be propped up. Use the steady rest or follow rest in conjunction with
the tailstock spindle to support longer parts and prevent the workpiece from flapping around
and flying away.
Risk of fire and explosion due to the use of flammable materials or cooling lubricants.
Before processing inflammable materials (e.g. aluminium, magnesium) or using inflamma-
ble auxiliary materials (e.g. spirit), it is necessary to take additional preventive measures in
order to avoid health risks.
When processing carbons, graphite and carbon-fibre-reinforced carbons, the machine is no
longer being used as intended. When processing carbons, graphite and carbon-fibre-rein-
forced carbons and similar materials, the machine can be damaged quickly, even if the
dusts generated are completely sucked out during the work process.
The processing of plastics with the lathe leads to static charge. The static charge of
machine parts from processing plastics cannot be safely conducted away from the lathe.
When using lathe dogs as carriers for rotating workpieces between the lathe centres, the
standard lathe chuck shield must be replaced with a circular lathe chuck shield.
1.5 Potential dangers that can be caused by the lathe
The lathe has been tested for operational safety. The construction and type are state of the art.
Nevertheless, there is a residual risk as the lathe operates with
high revolutions,
with 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 lathe is used and maintained by personnel who are not duly qualified, there may be a risk
resulting from incorrect or unsuitable maintenance of the lathe.

INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,
and strictly follow these operating instructions.
In the event of improper use
there may be a risk to personnel,
there is a risk of damage to the lathe and other property,
the correct function of the lathe may be affected.
Always disconnect the lathe, when cleaning or maintenance work is being carried out.
WARNING!
The lathe may only be used with the safety devices activated. Disconnect the lathe
immediately whenever you detect a failure in the safety devices or when they are not
mounted!
All additional devices installed by the operator have to be equipped with the prescribed
safety devices. As the operating company, this is your responsibility!
 "Safety devices“ on page 14
1.6 Qualification of personnel
1.6.1 Target group
This manual is addressed to
the operating companies,
the operators,
the maintenance personnel.
Therefore, the warning notes refer to both the operation and maintenance of the lathe.
Determine and indicate clearly who will be responsible for the different activities on the lathe
(operation, maintenance and repair).
Unclear responsibilities constitute a safety risk!
Always disconnect the main plug of the lathe and secure the main switch using a lock. This will
prevent it from being used by unauthorized persons.
The qualifications of the personnel for the different tasks are mentioned below:
Operator
The operator has been instructed by the operating company regarding the assigned tasks and
possible risks in case of improper behaviour. Any tasks which need to be performed beyond the
operation in standard mode must only be performed by the operator, if so indicated in these
instructions and if the operator has been expressively commissioned by the operating com-
pany.
Qualified electrician
With professional training, knowledge and experience as well as knowledge of respective
standards and regulations, qualified electricians are able to perform work on the electrical sys-
tem and recognise and avoid any possible dangers.
Qualified electricians have been specially trained for the working environment, in which they are

Stop the lathe immediately if there is a failure on the safety device or if it is not functioning for
any reason.
It is your responsibility!
If a safety device has been deactivated or is defective, the lathe can only be used again if you
the cause of the fault has been eliminated,
you have verified that there is no danger to personnel or objects.
WARNING!
If you bypass, remove or override a safety device in any other way, you are endangering
yourself and other persons working on the lathe. The possible consequences are:
injuries due to components or workpieces flying off at high speed,
contact with rotating parts and
fatal electrocution,
pulling-in of clothes.
The lathe includes the following safety devices:
a lockable main switch,
an emergency-stop switch,
a lathe chuck protection with position switch,
a screwed protective cover on the headstock,
a DC brake of the spindle drive,
protective covers on the machine bed,
a safety screw at the tailstock,
a protective cover on the lead screw an feed rod,
safety screws for the Camlock bolts on the workpiece holder,
a chips shield.
WARNING!
Although the isolating safety devices provided and delivered with the machine are
designed to reduce the risks of workpieces being ejected or parts of tools or workpieces
breaking off, they cannot eliminate these risks completely.
1.9.1 Lockable main switch
WARNING!
Dangerous voltage even if the main switch is switched off.
The areas marked by the pictogram might contain live parts, even if the main switch is switched
off.
In the "0" position, the lockable main switch can be secured against accidental or non-author-
ised switching on by means of a padlock.
The power supply is interrupted by switching off the main switch.
This excludes the points marked in the pictogram. In these areas there might be voltage, even if
the main switch is switched-off.

1.9.4 Protective covers of drive
DANGER!
The machine may only be started back up when all safety covers have been installed and
screwed on tightly.
The machine bed of the lathe is equipped with permanently installed safety covers. The screws
are properly connected with the covers and therefore can not be lost.
1.9.5 Lathe chuck protection with position switch
The lathe is equipped with a lathe chuck protection. The lathe can only be switched on if the
lathe chuck protection is closed.
1.9.6 Chip guard shield
Polycarbonate inspection windows, which have a safety-critical protective function in respect of
flying parts, must be visually inspected at regular intervals by responsible personnel provided
by the customer in order to guarantee the operational safety of the milling machine.
Polycarbonate viewing panes are subject to an ageing process and are classified as wear
parts.
The aging of polycarbonate windows can not be detected by visual inspection. It is therefore
necessary to replace the polycarbonate windows after a certain time.
Prolonged exposure from polycarbonate windows to cutting fluids can lead to accelerated age-
ing, i.e. deterioration of the mechanical properties (brittleness). Coolant vapours, detergents,
greases and oils or other corrosive substances from the operator side can also lead to a deteri-
oration of the polycarbonate windows. The result is a reduced retention capability of the poly-
carbonate viewing pane against chips and potentially flying parts.
1.9.7 Prohibition, warning and mandatory signs
INFORMATION
All warning and mandatory signs must be legible. They must be checked regularly.
1.10 Safety check
Check the lathe at least once per shift. Inform the person responsible immediately of any dam-
age, defects or changes in the operating function.
Check all safety devices
at the beginning of each shift (with the machine stopped),
once a week (with the machine in operation),
after all maintenance and repair work.
