Constructional changes
Implementation of structural changes
By conversions, changes, and reworking, e.g. additional threads,
holes, or safety devices can impair the functioning or safety of the
product or damage it.
• Structural changes should only be made with the written
approval of SCHUNK.
Spare parts
Use of unauthorized spare parts
Using unauthorized spare parts can endanger personnel and
damage the product or cause it to malfunction.
• Use only original spare parts or spares authorized by SCHUNK.
Use of special chuck jaws
Requirements of the chuck jaws
When using special chuck jaws, please observe the following rules:
• The chuck jaws should be designed to be as low as possible.
The clamping point must be as close as possible to the housing.
(clamping points at a greater distance cause higher surface
pressures in the jaw guidance and can significantly reduce the
clamping force.)
• Do not use welded jaws.
• Reduce operating pressure for higher clamping points.

Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
• Take appropriate protective measures to secure the danger
zone.
• Never step into the danger zone during operation.
Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
• Never rely merely on the response of the monitoring function
(dynamic pressure monitoring with pressure sensors) to avert
danger. Assume that the drive movement is faulty as long is the
installed monitors are not effective, since the effect depends
on the control and the current operating state of the drive.
Perform maintenance, modification and attachment work
outside of the danger zone defined by the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted.
Limit/prevent accidental access for people in this area due
through technical safety measures. The protective cover and
protective fence must be rigid enough to withstand the
maximum possible movement energy. EMERGENCY STOP
switches must be easily and quickly accessible. Before starting
up the machine or automated system, check that the
EMERGENCY STOP system is working. Prevent operation of the
machine if this protective equipment does not function
correctly.
