A. Crimp Function
If the jaws close too slowly or not at all the control button is fully depressed, perform the following:
1. Make sure that the air pressure is regulated at 552 kPa [80 psi] minimum to 689 kpa [100 psi]
maximum.
2. With the control button fully depressed, insert the tip of a screw driver through the rear exhaust port
and into the slot at the rear of the air valve spool. See Figure 10.
3. Turn the screw driver COUNTER–CLOCKWISE until the jaws are fully closed. Stop turning the screw
driver as soon as the jaws are closed and when there is no evidence of air escaping through the exhaust
ports.
