Setting internal pressure for the head can be achieved by turning the
primary regulator counter-clockwise until the knob stops.
Next, mark the knob of the regulator so that you have a reference point to
start from.
Using the reference point you just drew, turn the regulator 5 ½ to 6 ½
turns to reach a sufficient air pressure. (Approximately 80 to 85 PSI)
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 to the cycle. Likewise, if pressing the foot
pedal doesn’t fully open up the valve then full pressure will not be
reached either.
This can be checked by partially dismantling the foot switch and
checking the foot switch spring against the photo below to make sure the
part is in good condition. It should retain the illustrated shape when not
under pressure.
Please note that it is not necessary to dismantle the foot switch to
the point illustrated here in order to view the spring.
