After checking that there is no clearance between the stopper plate q and the knife w, loosen the bolt e and then
remove the knife w.
Insert the new w into the stopper plate q, and then tighten it with the bolt e.
NOTE: For L1 - L4 specifications, secure the stopper plate q in the position closest to you (the position indicated by
the dotted lines).
* When replacing the knife w, make sure that the knife number matches the number for the eyelet shape.
*
Replace the knife and hammer as a set.
*
If knives with different numbers are used on the same hammer, accurate cutting will not be possible, and
*
damage to the knife may result.
9-13. Adjusting the cutting pressure
Adjust the cutting pressure to the minimum pressure that still allows the material to be cut.
* If the knife cutting length is 20 mm, sufficient cutting performance can be obtained with an air pressure of 0.2 MPa.
To adjust the cutting pressure, adjust the air pressure of the knife pressure adjustment regulator q which is mounted
*
*
underneath the work table.

* If the material cannot be cut cleanly, do not increase the
cutting pressure over the maximum limit. Check the

contact between the knife and the hammer, while
referring to "9-11. Adjusting the contact between the knife
and the hammer".
