Cycle Time Adjustment
Two adjustments control the amount of time that the cutting cycle takes to complete:
1. The air pressure to the head is set at the primary regulator closest to the rear of the machine.
2. The first valve activated in the foot switch is supplied with air from the secondary regulator,
which is the one closest to the front of the machine. This, in turn, supplies air to the index
pins.
The primary regulator should be set at 80 to 85 PSI.
SOLUTION STEPS:
1. Setting internal pressure for the head can be achieved by turning the primary regulator
counter-clockwise until the knob stops.
2. Next, mark the knob of the regulator so that you have a reference point to start from.
3. Using the reference point turn the regulator 5 ½ to 6 ½ turns to reach a sufficient air pressure.
(Approximately 80 to 85 PSI)
4. The foot switch can also effect the cycle time of the machine. The valve should be fully
closed when the pedal is not depressed. If the valve is left partially open then the pressure to the
air bladder will need longer to build up, thus adding time onto the cycle. Likewise, if pressing the
foot pedal doesn’t fully open up the valve then full pressure will not be reached either.
