Adjusting Secondary Regulator
The secondary regulator is the one towards the front of the machine and controls
the 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.
ƒ Turn the secondary regulator knob all the way to the left, counter-
clockwise so that it is completely closed.
ƒ With the knob all the way to the left, push both of the index pins down
manually.
ƒ Slowly turn the secondary regulator back up to the right until BOTH
index pins just go up.
ƒ At the point when both pins go up, turn the regulator knob a half turn
further to set.
ƒ To decrease the force with which the index pins come down, turn the
regulator to the right ¼ turn at a time, until the desired pressure is
reached.
