1.2 Safety warnings (warning notes)
1.2.1 Classification of hazards
We classify the safety warnings into various levels. The table below gives an overview of the
classification of symbols (pictograms) and warnings for the specific danger and its possible con-
sequences.
Pictogram Alarm
expression Definition/Consequences
DANGER! Imminent danger that will cause serious injury or death to personnel.
WARNING! Risk: A danger that might cause serious injury or death to personnel.
CAUTION! Danger or unsafe procedure that might cause injury to personnel or dam-
age to property.
ATTENTION!
Situation that could cause damage to the machine and product and other
types of damage.
No risk of injury to personnel.
INFORMATION
Application tips and other important or useful information and notes.
No dangerous or harmful consequences for personnel or objects.
In the case of specific dangers, we replace the pictogram
or
General danger with a warning of injuries to hands, hazardous
electrical voltage,rotating parts.

1.2.2 Other pictograms
1.3 Proper use
WARNING!
Improper use of the lathe
will endanger personnel,
will endanger the machine and other material property of the operator,
may affect proper operation of the machine.
The machine is designed and manufactured to be used in environments where there is no
potential danger of explosion.
The lathe is designed and manufactured for straight turning and facing round or regularly
formed three-, six- or twelve-square workpieces in cold metal, castings and plastics or similar
materials that do not constitute a health hazard or do not create dust, such as wood, Teflon®,
etc. The lathe must only be installed and operated in a dry and well-ventilated place. The work-
pieces may only be clamped in the lathe chuck using self ejecting chuck-key provided.
If the lathe is used in any way other than described above, or modified without authorization,
then the lathe- is being used improperly.
We do not take liability for damage caused by improper use.
We would like to stress that any modifications to the construction, or technical or technological
modifications that have not been authorized will also render the warranty null and void.
It is also part of proper use that
the maximum values for the lathe are complied with,
the operating manual is observed,
inspection and maintenance instructions are observed.
 "Technical data“ on page 16
In order to achieve company cutting performance, it is essential to choose the right turning tool,
feed, tool pressure, cutting speed and coolant.
WARNING!
Very serious injury due to improper use.
It is forbidden to make any modifications or alterations to the operating values of the
machine. These could endanger personnel and cause damage to the machine.
Be aware of
slipping! Activation forbidden! Pull the mains plug! Use protective gog- gles! Use ear protection!
Use protective
gloves! Use protective boots! Wear a safety suit! Protect the environ- ment! Contact address

1.4 Possible dangers caused by the machine
The lathe 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.
Nonetheless, there remains a residual risk, since the machine operates with
high revolutions,
rotating parts,
electrical voltage and currents.
We have used construction resources and safety techniques to minimise the health risk to per-
sonnel 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 operation or unsuitable maintenance.
INFORMATION
All personnel involved in assembly, commissioning, operation and maintenance must
be duly qualified,
follow this operating manual.
Disconnect the machine from main power source whenever cleaning or maintenance work is
being carried out.
WARNING!
The lathe may only be used with the safety devices activated.
Disconnect the lathe from main power source whenever you detect a failure in the safety
devices or when they are not fitted!
All additional installations carried out by the operator must incorporate the prescribed
safety devices.
As the machine operator, this will be your responsibility!
 "Safety devices“ on page 11
1.5 Qualification of personnel
1.5.1 Target group
This manual is addressed to
operators,
users,
maintenance stuff.
The warning notes therefore refer to both operation and maintenance of the machine.
Always disconnect the machine plug from the from main power source. This will prevent it being
used by unauthorized personnel.
INFORMATION
All personnel involved in assembly, commissioning, operation and maintenance must
be duly qualified,
follow this operating manual.
In the event of improper use
there may be a risk to personnel,
there may be a risk to the machine and other material property,
correct functioning of the lathe may be affected.

Page 10
TU2506 ǀTU2807VUS
1.5.2 Authorized personnel
WARNING!
Incorrect use and maintenance of the machine constitutes a danger for personnel,
objects and the environment.
Only authorized personnel may operate the machine!
The only personnel authorized to use this machine and perform maintenance on it are trained
and instructed technical staff working for the operator and manufacturer.
1.5.3 Obligations of the operator
The operator must instruct staff at least once a year on
all safety standards that apply to the machine,
operation,
accredited technical guidelines.
The operator must also
check staff's understanding,
document training/instruction,
require staff to confirm participation in training/instruction by means of a signature,
check whether the staff are aware of safety and of dangers in the workplace and whether
they observe the operating manual.
1.5.4 Obligations of the user
The user must
have read and understood the operating manual,
be familiar with all safety devices and regulations,
be able to manipulate the machine.
1.5.5 Additional qualification requirements
For work on electrical components or equipment there are additional requirements:
This work must only be carried out by a qualified electrician or person working under the
instructions and supervision of a qualified electrician.
Before carrying out work on electric components or operating units the following measures
must be taken, in the order given.
Disconnect all main electrical power.
Ensure that the machine cannot be turned on again.
Check that there is no voltage.
1.6 User positions
The user must stand in front of the machine.
1.7 Safety measures during operation
CAUTION!
Risk due to inhaling health hazardous dusts and mist.
Depending on the material being processed and any additional dusts and mist in the
work area, conditions might impair your health.
Make sure that the generated health hazardous dusts and mist are safely removed at the
point of origin and are collected and/or filtered from the working area. Use an
appropriate dust collection/filter unit.
