TROUBLESHOOTING

SITUATION

POSSIBLE CAUSE (REMEDY)

TOTAL LOSS OF PRESSURE, DIAPHRAGM HAS NO MOVEMENT OR MOVEMENT CAN BE STOPPED...CONTINUED.

2.Air lock created on hydraulic side of pump. (air entering hydraulic side due to loose hydraulic feed line fittings, (ref# 63), punctured hydraulic feed line, poor seal at hydraulic intake valve, (ref# 62), or elbow, (ref# 61). Tighten hydraulic feed line, test for leaks, or apply Teflon tape or pipe sealant on fittings. Purge air as per detailed instructions below).

3.Pressure control valve ball (ref# 87) worn out/jammed. (remove hydraulic return line, (ref# 72), from pressure control valve fitting, (ref# 81). Remove pressure control valve, (ref# 73), from elbow, (ref# 61). Disassemble pressure control valve, by removing valve seat, (ref# 86), from body, (ref# 82). Inspect for and remove foreign material. Inspect ball for wear. Install pressure control repair kit, (ref# 88), if necessary).

4.Piston rod (ref# 93) disconnected from piston (ref# 91). (reconnect piston rod following detailed instructions on page 28-29).

NO PRESSURE, BLUE HYDRAULIC FLUID IN PAINT

1.Diaphragm broken. (replace with complete diaphragm, (ref# 51). Closely follow detailed instructions on page 26. NOTE; If, and only if, paint has contaminated the hydraulic side of the pump, the entire hydraulic system must be cleaned and flushed. Make sure to remove and clean the hydraulic tank screen, (ref# 66), during this process. Refill only with genuine H.E.R.O. LVO hydraulic fluid.

NOTE; If lacquer has contaminated the hydraulic system, the piston seal, (ref# 90), must be changed in addition to flushing the system. Closely follow detailed instructions on page 28-29).

HYDRAULIC SIDE OF PUMP HAS BEEN REPAIRED AND REASSEMBLED, DIAPHRAGM NOT MOVING "PURGING"

1.Air lock created on hydraulic side of pump. (when the hydraulic side of the pump is working there is no air in it. During repairs it is possible that air has been trapped in the hydraulic system. It must be removed or the pump will not work. To purge the air from the hydraulic system; remove the pressure control knob, (ref# 74), from the valve. Gently pull the P.C. stem, (ref# 77), out. It will pull out about 1/8". Remove the vented hydraulic cap, ref# 68), from the hydraulic tank, (ref# 65), and install accessory pressure cap, item 4-45-3. With a bicycle pump, apply a few pounds of air pressure to the hydraulic tank. This will force the oil through the hydraulic system and push out any of the trapped air. Wait a few minutes. Remove pressure cap and replace with vented cap. Restart the unit and install pressure control knob.

NOTE: Unit may be running during purging procedure to speed up the procedure. If a pressure cap is unavailable, simply running the equipment for approximately 5-10 minutes with the P.C. stem pulled out, will purge the system).
