Adjusting Secondary Regulator
The secondary regulator is the one towards the front of the machine and controls pressure delivered
to the index pins. It is called the secondary regulator. While there is no gauge to check the internal
pressure driving the machine, there is an easy way to reset the regulator to factory settings.
SOLUTION STEPS:
1. Turn the secondary regulator knob all the way to the left, counter-clockwise so that it is completely
closed.
2. With the knob all the way to the left, push both of the index pins down manually.
3. Slowly turn the secondary regulator back up to the right until BOTH index pins just go up.
4. At the point when both pins go up, turn the regulator knob a half turn further to set.
5. To decrease the force with which the index pins come down, turn the regulator to the right until the
desired pressure is reached.
