2 Basic safety notes
Improper handling, assembly and maintenance of this product
may result in risk to persons and equipment if this operating
manual is not observed.
2.1 Appropriate use
lThe product is used for clamping metal and plastic workpieces
on machine tools.
lThe product may only be used within the scope of its technical
data.
lThe product is intended for industrial and commercial use.
lAppropriate use of the product includes compliance with all
instructions in this manual.
lThe maximum speed and the necessary clamping force must
be determined by the operator for each clamping task in
accordance with the valid standards or technical
specifications of the manufacturer.
(See also "Calculation for clamping force and speed of
rotation" in the chapter "Technical data").
lUse suitable top jaws with a suitable interface.
lThe interference circuit diameter of the workpiece must be
smaller or at most equal to the outer diameter of the
clamping device.
lThe workpiece must not experience plastic deformation under
clamping force (clamping pressures are permissible).
2.2 Inappropriate use
The product is not being used appropriately if:
lthe product is used as a press, a punch, a toolholder, a load-
handling device or as lifting equipment.
lthe specified technical data for use of the product are
exceeded.
lworkpieces are not properly clamped, paying particular
attention to the specified clamping forces.
lthe top jaws are not mounted properly.
lthe product is not being operated properly.
lthe product is operated in the stroke end positions.
lthe guideways are overloaded due to the chuck jaws being
too high or the clamping point being selected too high.
lthe product has been insufficiently maintained.
lthe product is brought into contact with aggressive media,
especially acids.
lthe product is used in abrasive blasting processes, especially
sandblasting.

2.3 Structural changes
Implementation of structural changes
Modifications, changes or reworking, e.g. additional threads,
holes, or safety devices, can damage the product or impair its
functionality or safety.
lStructural changes should only be made with the written
approval of SCHUNK.
2.4 Spare parts
Use of unauthorized spare parts
Using unauthorized spare parts can endanger personnel and
damage the product or cause it to malfunction.
l
Only use original spare parts and spares authorized by SCHUNK.
2.5 Ambient conditions and operating conditions
Required ambient conditions and operating conditions
Incorrect ambient and operating conditions can make the
product unsafe, leading to the risk of serious injuries,
considerable material damage and/or a significant reduction in
the service life of the product.
lMake sure that the product is only used within its defined
application parameters.
lEnsure that the product is of a sufficient size for the
application.
lEnsure that maintenance and lubricating intervals are
observed.
lOnly use cooling emulsions with anti-corrosive additives
when machining.
Depending on the operating conditions, the function and
clamping force must be checked after a certain period of
operation.
With the smallest possible actuation pressure on the clamping
cylinder, the base jaws should move evenly. This method is not a
substitute for measuring the clamping force.
If the clamping force has dropped too much or if the base jaws
and/or the release mechanism no longer move properly, the
clamping device must be disassembled, cleaned, and relubricated.
2.6 Material limitations
The product is made of steel alloys, elastomers, aluminum alloys
and brass. In addition, Linomax plus grease, Branotect anti-rust
oil and Renolit HLT2 are incorporated into the product as auxiliary
and operating materials. The safety data sheet for LINOMAX plus
can be found at www.schunk.com.

2.7 Chuck Jaws
Requirements of the chuck jaws
Rotational or if applicable, accumulated energy, can make the
product unsafe and risk the danger of serious injuries and
considerable material damage.
lChange chuck jaws at a standstill and without a clamped
workpiece.
lDo not use welded jaws.
lDesign the chuck jaws to be as light and as low as possible.
The clamping point must be as close as possible to the chuck
face (clamping points at a greater distance lead to greater
surface pressure in the jaw guidance and can significantly
reduce the clamping force).
lIf the clamping point is at a greater distance from the
housing, the operating pressure must be reduced.
lAfter a collision, the clamping device and the chuck jaws must
be subjected to a crack detection test before being used
again. Replace damaged parts with original SCHUNK spare
parts.
lThe chuck jaw mounting screws and if present, the T-nuts,
must be replaced if there are signs of wear or damage. Only
use screws of quality grade 12.9 in compliance with the
specified tightening torques. For clamping devices with fine
serration, the jaw mounting screws must be screwed into the
holes closest to the clamping point.
2.8 Personnel qualifications
Inadequate qualification of personnel
Any work on the product by inadequately qualified personnel can
lead to serious injuries and considerable material damage.
lAll work must be performed by appropriately qualified
personnel.
lPersonnel must have read and understood the complete
manual before beginning any work on the product.
lObserve country-specific accident prevention regulations and
the general safety notes.
The following personnel qualifications are required for the
various activities on the product:
