    Steps:

  1. Find the Mac valve that controls the air for the equipment.
  2. The port on the left side of the Mac Valve is the exhaust and the one in the center is the air in port. This one has a regulator that must be set to 60 PSI (retract function)
  3.  On the right side of the Mac Valve, we have 2 ports.  The one on top (#2) is normally closed and has a regulator.  This is the one we use for an inward (extended) position. This regulator must be set to 10-15 PSI for DS and 10-25 PSI for the PS. You will have to press the silver bottom to adjust the regulator for the desired PSI turning the knob on the bottom of the regulator, clockwise, increases the PSI and CCW decreases the PSI.
