ARBUS 400
Whenever problems affect JACTO machines
fitted with piston cup-type pumps, try to ca-
tegorize the same within one the four groups
listed below.
a. Suction and boost deficiency
• No liquid comes out from the nozzles;
• No liquid is flowing back to the reservoir;
• No pressure is indicated on the pres-
sure regulator.
b. Insufficiency of pressure (partial lack of
pressure)
• The liquid is not sprayed at the proper
pressure (A);
• The spraying angle is smaller than the
specified angle (B);
• The gauge shows lower pressure (C)
c. Pressure oscillation
• The gauge pointer is oscillating (D);
• The jet spraying angle oscillates (E).
d. Intermittence
• The gauge pointer vibrates intense-
ly (F);
• The pressure hoses vibrate intensely;
• The jet spraying angle exhibits pul-
sating variation (G).
