5.3 Work piece cutting

5.3.1 Prerequisites

ATTENTION!

Damage to the machine

The knife may be damaged when the machine is operated wit-
hout hose prestressing.
• Never cut without bending (X).
• Adjust the bending pin and the workpiece.

Prerequisites for a correct cutting process:
•

The bending pin position and the hose diameter are matched to
each other:
–

(1) Large hose diameter = large bolt distance

–

(2) Small hose diameter = small bolt distance
