9. STANDARD ADJUSTMENTS
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 cutting pressure is increased to more than is
*
necessary, it will cause the hammer to become worn or
the knife to become damaged.
* 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".

* 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.
