"Diaphragm Test"

The solution to almost all problems can be found in the paint side valves, due to the increased wear from contact with the abrasive paint/spray materials. Intake valve (ref# 16-23) and Outgo valve (ref#32) make up the paint valves. Refer to pages where exploded views of these valves are shown.

To eliminate the hydraulic side of the pump (piston / oil side of diaphragm) as a source of problems;

1.Remove the intake valve end cap (ref# 16) by removing the four cap screws (ref# 14). Set aside the spring (ref# 20 ).

2.Start unit.

3.Increase the pressure by turning the pressure control knob (ref# 71) clockwise to full pressure.

4. Put pressure on the center of the exposed diaphragm with the handle of a screwdriver or other blunt object.

NOTE: The diaphragm is located between the paint head (ref# 23) and the hydraulic head (ref# 51)

5.If you are:

-UNABLEto stop or alter the diaphragm's movement, then the hydraulic side is operating properly. The problem is located in the “Paint” pump. See troubleshooting guide for additional information.

-ABLEto stop or alter the diaphragm's movement, then the hydraulic pump is not operating properly. The problem is located in the “Hydraulic” pump. See troubleshooting guide for additional information.
