Service manual

4) Remove the two screws from the

electrical socket with a 3/32”

Allen wrench and 5/16” wrench

(see photo), and remove the

socket and wires from the panel.

5) Mount the replacement wire harness to the top of the pneumatics panel. Orient the

cable socket in the same manner as the original, and make sure to mount the

ground wire terminal so that the metal tab is in contact with the panel plate. Tighten

both mounting screws snugly.

6) Reconnect each of the 3 PC control wires to their respective valves, and plug the

main controller cable plug back into the socket on top of the panel. Turn the locking

collar clockwise until you feel a slight detent, indicating that it is fully connected.

7) Power up the machine and check the pneumatic operation by cutting a test mat.

Button Clamp Pneumatic Cylinder Replacement

Any of the button clamp cylinders may be replaced if the “lip” of the button is broken.

Verify the type of air fitting at the rear of the clamp cylinder; either an “L” or “T” type

connector. The top most vertical clamp, and furthest right horizontal clamp cylinders are

the only ones with an “L” type pneumatic fitting.

(part # -“L” connector: 12-840, “T” connector:

#12-839 )

1) Remove any mat board or slip sheet(s)

from the cutting board. Disconnect the main

air hose from the pneumatics panel.

2) Disconnect the black and clear air hoses

from the rear of the clamp cylinder. Push

inward on the locking collar as you pull on

the hose to remove. (For “T” type

connectors, do not be concerned with

marking the hoses for re-installation; only

the hose color is important with regard to

reconnecting to fittings.)
