5 Use and limits of use

5.1 Use

The product is a clamping device that may only be used to
clamp a workpiece to enable it to be machined.

Only ever operate the product with a suitable fluid.

As well as for its general field of application, this product
was designed and developed for use, when necessary, in a
specific and documented application [see clamping situa-
tion drawing or order confirmation].

Any other fields of application require the explicit approval
of the manufacturer.

With the help of suitable adaptation clamping devices from
the manufacturer, the clamping device can rapidly be con-
verted to suit a different clamp setting.

5.2 Limits of use

Limits are set on the operation of clamping head chucks in
the area where workpieces are machined.

Specifically, before using these clamping head chucks, four
separately independent limits need to be checked.
