5.1.1 Replacing the reduction inserts
• Unscrew the already mounted reduction inserts.
• Screw on the reduction inserts with the corresponding diameter.
• If necessary (e.g. T-pieces), the fixed outside clamping tool can be dismantled by unscrewing
the three allen screws.

5.1.2 Using small and large reduction inserts
Small reduction inserts:
• Pipe fittings often only have a short straight surface area on which they can be clamped.
• Fittings often need to be clamped in the inside clamping tools with the narrow reduction
inserts.
• In case of welding fittings (elbows, T-pieces etc.) the inside narrow reduction insert can also
be used flush with the outside.
