Troubleshooting
Relieve the pressure (page 7) before checking or repairing the equipment.
To repair the regulator, refer to page 10.
Problem Cause Solution
No fluid flow. Plugged fluid inlet. Flush fluid line and regulator.
Exhausted fluid supply. Check fluid supply and supply
pump.
No air inlet pressure. Check air inlet pressure.
Ruptured air diaphragm (15). Replace. See page 10.
Ruptured fluid diaphragms (9a, 9b). Replace. See page 10.
Low fluid flow. Incorrect ratio. Use correct spacer (3) and ratio pis-
ton (14) for desired ratio. See
Change the Ratio, page 10.
Fluid supply pressure is too low. Increase fluid pressure. Do not
exceed 300 psi (2.1 MPa, 21 bar).
Air inlet pressure is too low. Increase air inlet pressure.
High fluid flow. Incorrect ratio. Use correct spacer (3) and ratio pis-
ton (14) for desired ratio. See
Change the Ratio, page 10.
Air inlet pressure is too high. Decrease air inlet pressure.
Erratic fluid flow. Damaged fluid diaphragms (9a, 9b). Replace. See page 10.
Ruptured air diaphragm (15). Replace. See page 10.
Ruptured fluid diaphragms (9a, 9b). Replace. See page 10.
Inconsistent air inlet pressure. Check air inlet pressure.
Inconsistent fluid inlet pressure. Check fluid inlet pressure.
