accompany it.
Illustrations in this manual are there to facilitate a basic un-
derstanding, and may differ from the actual design configu-
ration of the product.

by inappropriate combinations of them!
Read and pay attention to all operating instruc-
tions for individual products and combinations of
them.
1.2 Key to symbols Safety instructions in this manual are designated by sym-
bols. The safety notices are invoked by signal words that ex-
press the level of hazard involved.

1.3 Definition of terms
1.3.1 Release setting Release setting means that the clamping device is released.
If the clamping device is released, this also releases the
workpiece.
1.3.2 Complete clamping reserve
Complete clamping reserve means that the clamping device
is clamped without a workpiece. The complete stroke has
been used up, which means that the clamping device is
therefore at the limit position for clamping reserve.

specifications as well as those in the manual for the machine
tool.
No modifications must be made to the product. The operator
is wholly and solely responsible for any resultant personal
injury and/or damage to materials.
Excepted from this are changing parts that HAINBUCH ap-
proved explicitly for autonomous machining, but specified
limits must never be exceeded.

centrifugally due to a drop in actuating force / sup-
ply pressure!
On the machine, ensure that the actuating force /
the supply pressure do not drop while the product
is in use.
If no precautions have been taken onthe machine
to maintain the actuating force / the supply pres-
sure, it is prohibited to use this product on the ma-
chine.
