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

2.1 Emissions
The level of noise emitted by the lathe is less than 70 dB(A).
INFORMATION
If the lathe is installed in an area where various machines are in operation, the acoustic influ-
ence (immission) on the operator of the lathe may exceed the legally permitted peak value in the
workplace.
We recommend the use of soundproofing and ear protection.
3. Assembly
INFORMATION
The lathe comes pre-assembled.
3.1 Extent of supply
When the machine is delivered, check immediately that the lathe has not been damaged during
shipping and that all components are included. Also check that no fastening screws have come loose.
Compare the parts supplied with the information on the packaging list.
3.2 Transport
WARNING!
Machine parts falling off forklift trucks or other transport vehicles could cause very seri- ous
or even fatal injuries. Follow the instructions and information on the transport case:
ЬCentres of gravity
ЬSuspension points
ЬWeights
ЬMeans of transport to be used
ЬPrescribed shipping position
WARNING!
Use of unstable lifting and load-suspension gear that might break under load can cause very serious
injuries or even death.
Check that the lifting and load suspension gear has sufficient load capacity and that it is in perfect
condition. Observe the rules for preventing accidents.
Hold the loads properly.
Never walk under suspended loads!

17
3.3 Storage
ATTENTION!
Improper storage may cause important parts to be damaged or destroyed.
Store packed or unpacked parts only under the intended environmental conditions.
Consult JPW (Tool) AG if the lathe and accessories have to be stored for a period of over
three months or under different environmental conditions to those given here.
3.4 Installation and assembly
3.4.1 Requirements of the installation site
Organize the work area around the lathe in accordance with local safety regulations.
Operation, maintenance and repair in the work area must not be hindered.
INFORMATION
The mains plug of the lathe must be freely accessible.
3.4.2 Load suspension point
ėFasten the load suspension gear around the lathe bed.
ė Make sure that you distribute the loads evenly so that the lathe cannot turn over while lifting.
ė Make sure that no add-on pieces or varnished parts are damaged due to the load suspension.
3.4.3 Installation
WARNING!
Danger of crushing and overturning. The lathe must be installed by at least 2 people.
ėCheck the horizontal orientation of the base of the lathe with a spirit level.
ėCheck that the foundation has sufficient floor-load capacity and rigidity.
ATTENTION!
Insufficient rigidity of the foundation leads to the superposition of vibrations between the machine and
the foundation (natural frequency of components). Insufficient rigidity of the entire lathe assembly also
rapidly causes the lathe to reach critical speeds, with unpleas- ant vibrations, leading to bad turning
results.
ė Position the lathe on the intended foundation.
ė Secure the lathe to the foundation or substructure of the machine using the (4) through holes.
If necessary, use anti-vibration elements (model S1) for your machine substructure.
INFORMATION
The installation site must be designed in accordance with ergonomic workplace requirements. The
installation drawings described below may differ from the real dimensions (cast parts). The
tolerances are in the range of the general tolerances according to DIN 7168 g.

3.4.4 Installation drawing BD-11
ATTENTION!
Tighten the fastening screws on the lathe only until it is firmly secured and cannot move during operation.
If the fastening screws are too tight and the foundation is uneven, the bed of the lathe may break.
3.5 First use
WARNING!
Personnel and equipment may be endangered if the lathe is first used by inexpert per- sonnel.
We do not take liability for damage caused by incorrect commissioning.

19
3.5.1 Cleaning and greasing
ė Remove the anticorrosive agent applied to the machine for transport and storage purposes.
We recommend the use of stove distillate.
ė Do not use any solvents, thinners or other cleaning agents which could corrode the varnish on the machine.
Follow the specifications and indications of the manufacturer of the cleaning agent.
ė Lubricate all bright machine parts with non-corrosive lubricating oil.
ė Grease the machine using the lubrication chart.
“Inspection and maintenance“ on page 44
3.5.2 Visual inspection
Check the oil level in the inspection glass of the feed gear.
( “Oil inspection glass of the feed gear“ on page 45)
3.5.3 Run test
ėCheck smooth running of all spindles.
INFORMATION
For manufacturing engineering reasons and for reasons of precision of fit, there may be occa- sional slight stiffness
in the spindles. This will disappear after a short time in use.
ėCheck the state of the lathe chuck and the turning jaws.
3.5.4 Power connection
Connect the following cables:
ė Connect the electric supply cable.
ė Check the fuse protection of your power supply against the technical data for the total con- nection value of the
lathe.
ATTENTION!
Please pay attention that all three phases (L1, L2, L3) are connected correctly. Most engine failure
result from incorrect connection, for instance the neutral
conductor ( N ) is being connected to a phase.
This might lead to the following results:
Ь The engine does get quickly very hot.
Ь The engine noise increases, i.e. becomes louder.
Ь The engine has no power.
When the phases are connected wrongly, the guarantee is being null and void.
ATTENTION!
Lathes with frequency converter must not be operated with a CEE plug. Connect the machine
permanently to a connection box (see EN 50178 / VDE 5.2.11.1)
Ь BD-11 lathe
INFORMATION
On lathes of the type "VARIO" the frequency converter (driving regulator) might release the FI protected switch of
your electrical supply. In order to avoid malfunction, you either need an FI protected switch sensitive for pulse
current or AC/DC sensitive.
In case of a mulfunction or release of the FI protected switch, please check the type installed. The following signs
indicate if you have one of the FI protected switches described above.
