1.2 Proper Use
WARNING!
Improper use of the lathe
Ь will endanger personnel,
Ь will endanger the machine and other material property of the operator,
Ь 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 workpieces may only be clamped in the
lathe chuck using the special check-key provided.
If the lathe is used in any way other than as described above, modified without the authorisation of JPW
Machine or operated with different process data, then it 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 authorised by JPW Machine will also render the guarantee null and
void.
It is also part of proper use that
Ь the maximum values for the lathe are complied with,
Ь the operating manual is observed,
Ь inspection and maintenance instructions are observed.
In order to achieve 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.
1.3 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
Ь high revolutions,
Ь rotating parts,
Ь electrical voltage and currents.
We have used construction resources and safety techniques to minimise the health risk to per- sonnel
resulting from these hazards.

9
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
Ь be duly qualified,
Ь follow this operating manual.
Disconnect the machine whenever cleaning or maintenance work is being carried out.
WARNING!
THE LATHE MAY ONLY BE USED WITH THE SAFETY DEVICES ACTIVATED.
Disconnect the lathe 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
1.4 Qualification of personnel
1.4.1 Target group
This manual is addressed to
Ь operators,
Ь users,
Ь maintenance stuff.
The warning notes therefore refer to both operation and maintenance of the machine.
Determine clearly and unequivocally who will be responsible for the different activities on the
machine (use, maintenance and repair).
Vague or unclear assignment of responsibilities constitutes a safety hazard!
Always disconnect the machine plug from the mains. This will prevent it being used by
unauthor- ised personnel.
INFORMATION
All personnel involved in assembly, commissioning, operation and maintenance must
Be duly qualified
follow this operating manual.
