Adjustment Instructions
The operating pressure of this unit was set at the factory to the maximum rating (at full speed).
See General Data. However, this pressure may be reset down to 150 psi (1050 kPa).
1.
WITH UNIT STOPPED
, loosen nut (E) to relax spring (G).
2. Loosen nut (H). Turn rod (L) in Air Cylinder (AC) until approximately 3/4 inch
(20 mm) between nut (H) and flat on rod (L).
3. Turn rod (L) one round into rod end bearing. Tight nut (H). Rotate butterfly
shaft/lever (C), open and close, several times to assure that linkage is not
binding.
4. With air cylinder rod (L) fully extended, take slack out of spring (G) by moving
nuts (E) and (F). Tighten nuts.
5. Start unit and allow to warm up for 3 to 5 minutes.
6. Push “Service Air” button on control panel.
7. With service air valve closed, adjust pressure regulator (PR) to rated pressure
(350 psi) plus 10 psi (70 kPa) as follows:
8. Loosen locknut (M) counterclockwise. Turn adjustment cap (N) clockwise to
increase pressure, counterclockwise to decrease pressure.
9. Open service air valve and observe full load engine speed (*). Adjust regulator
to give rated operating pressure (*). Tighten locknut (M).
10. Close and slowly open service air valve. If engine speed surges, increase
tension on spring (G) by moving nuts (E) and (F).
11. To regulate to any pressure between 150 psi (1050 kPa) and maximum rating
(350 psi), make adjustments at the pressure regulator.
