2.1 Intended use
The clamping device may only be used in accordance with the technical data. The clamping device
has been designed for stationary application on milling machines in an industrial environment.
Using the device in accordance with the intended purpose includes compliance with the
commissioning, installation and operating instructions, and with the environmental and service
conditions as provided by the manufacturer.
The manufacturer accepts no liability for damage resulting from non-intended use.

2.2 Reasonably foreseeable misapplication
Any application that is not in accordance with the "Intended use" or exceeds such
intended use is considered not in accordance with the regulations, and is forbidden.
Any other use of the device is subject to confirmation from the manufacturer.
Examples of forseeable misapplication
 Clamping device used on rotating systems.
 Clamping widely protruding workpieces.
 Clamping of havy workpieces in vertical position without an additional safeguard to prevent the
workpiece falling out during loading and unloading.
Alterations and modifications 2.2.1
In the case of unauthorised alterations and modifications of the clamping device, the
manufacturer's liability ceases and any warranty is voided.
Spare and wear parts and auxiliary material 2.2.2
Only use original parts or parts approved by the manufacturer. Using spare and wear
parts by third party manufacturers may lead to risk.
2.3 Residual risk
The user is responsible for applying the correct workpiece tension.
New clampings have to be carefully checked by qualified personnel with relevant training.
One always needs to allow for the risk that the workpiece may slip or be dislodged, even
when the clamping device is functioning correctly. This is due to the different geometries
to be clamped, contact surfaces, clamping friction values, processing force, wrong
manipulation of the milling machine etc.
Protective devices are to be attached to the processing machine that will protect the
operator from any tool or workpiece parts that may be ejected.
It is mandatory that operators and others in the proximity of the processing machine
wear protective goggles.
Do not use methods of operation that impair the function and operational safety.
Jaw change 2.3.1
Damage may result if system jaws are insufficiently tightened.
Notes on clamping technology 2.3.2
The operator is responsible for ensuring that the clamping geometry and clamping forces
are suitable for the intended processing.
We recommend that clamping be carried out with a torque wrench in order to achieve
consistent clamping results.
The clamping forces can only be achieved if the clamping device functions correctly
and the workpiece is correctly held in the device.
Regular servicing and cleaning in accordance with the operating instructions is
mandatory in order to ensure correct function.
When clamping thin-walled elastic workpieces, e.g. tubes or packages, it is possible
that the clamping force is significantly reduced due to yielding of the workpiece.
When clamping with a high degree of force, the clamping force is significantly reduced
due to the increased frictional forces in the carriages.
2.4 Duties of the organisation in charge
The organisation in charge of the device undertakes to only allow operatives to work on the device:
 who are familiar with the basic health and safety regulations and regulations for the
prevention of accidents.
 who have completed appropriate induction for working with the machine.
 who have read and understood these operating instructions.
The requirements of the EC Directive 2007/30/EC on the use of work machinery must be
complied with.
2.5 Operator duties
All persons who have been instructed to work with the machine undertake to:
 observe the basic regulations for health and safety and for the prevention of accidents.
 read and understand the section on safety and the safety instructions in these operating
instructions prior to working with the machine, and to observe these instructions.
2.6 Operator qualification
The installation, initial setup, fault analysis and periodic monitoring have to be carried out
by competent personnel with the relevant qualifications.
2.7 Personal protective equipment
Warning:
Risk of eye injury through ejected hot chips!
Ejected hot fragments can lead to serious eye injury.
The regulations for safety at work and the prevention of
accidents always have to be observed when working
with the machine.
Personal protection equipment must be worn at all times,
in particular safety boots, gloves and safety goggles.
2.8 Warranty
The warranty period is 24 months from the date of delivery, the warranty applies subject
to being used as intended and to the following conditions:
 Compliance with concurrent documents.
 Compliance with environmental and operating conditions.
 Compliance with the specified maintenance and lubrication intervals.
 Observance of the maximum service life.
Any parts in contact with workpieces are not covered by the warranty.
Warranty – Maximum service life
24 months or 50‘000 clamping cycles
