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 lathe operator must be qualified.  Target group private users on page 10
1.4.1 Avoiding misuse
Use of suitable cutting tools.
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
forbidden 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,
permanent 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
inflammable 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-
reinforced 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.  Target group private users

3 Delivery, interdepartmental transport and unpacking
CAUTION!
Injuries caused by parts falling over or off a forklift, pallet truck or transport vehicle. Only
use means of transport that can carry the total weight and are suitable for it.
3.1 Notes on transport, installation and unpacking
Improper transport of individual devices and minor machines, unsecured devices and minor
machines stacked on top of each other or next to each other in packed or already unpacked
condition is accident-prone and can cause damage or malfunctions for which we do not grant
any liability or guarantee.
Transport the scope of delivery secured against shifting or tilting with a sufficiently dimen-
sioned industrial truck to the installation site.
3.1.1 General risks during internal transport
CAUTION: DANGER OF TIPPING!
The device may be lifted unsecured by a maximum of 2cm.
Employees must be outside the danger zone, the reach of loads. Warn employees and, if
necessary, advise employees of the hazard.
Act responsibly during transport and always consider the consequences. Refrain from daring
and risky actions.
Gradients and descents (e.g. driveways, ramps and the like) are particularly dangerous. If such
passages are unavoidable, special caution is required.
Before starting the transport check the transport route for possible danger points, unevenness
and disturbances as well as for sufficient strength and load capacity.
Danger points, unevenness and disturbance points must be inspected before transport. The
removal of danger spots, disturbances and unevenness at the time of transport by other
employees leads to considerable dangers.
Careful planning of internal transport is therefore essential.

Check the horizontal orientation of the base of the lathe with a spirit level.
Check that the foundation has sufficient load-bearing capacity and rigidity.
Anchor the machine base or the optional machine base onto the floor before positioning the
machine on it.
Make sure that a sufficiently stable lifting sling (tape sling) is used that can bear the weight.
Place the lifting sling around the spindle behind the lathe chuck (2) and then around a rib
(4) of the machine bed. Then hook the end of the sling back into the crane hook (5). Push
the tailstock as far forward as possible. Pay attention to the load centre of gravity, if
necessary adjust the position of the sling in the crane hook (3).
Raise the lathe only as far as is necessary to carry out the work.
