5.1.1 Replacing the Reduction Inserts
Unscrew the mounted reduction inserts by means of the provided Allan key.
Screw the reduction inserts with the corresponding diameter into the clamping devices.
If necessary (e.g. for T-pieces) the outer fixed clamping device can be dismantled by unscrewing
the three hexagon socket screws.

5.1.2 Using Small and Large Reduction Inserts
Small Reduction Inserts:
Pipe fittings often have only a short straight surface area on which they can be clamped.
Fittings mostly need to be clamped in the inner clamping devices with the small reduction
inserts.
When fittings are to be welded (bends, T-pieces etc.), the inner small reduction insert can also be
used flush to the inside or to the outside.

Large Reduction Inserts
They are mainly used for a good tightening and are generally mounted on the inner
clamping devices.
Super large reduction inserts have a specially high guidance quality and are mainly
used during the welding of fittings with long legs which can only be clamped with a single
clamping tool.
