them in one of the following four groups.
a. Lack of suction and pumping capacity
• No liquid flow through the nozzles.
• No return to the tank.
• Pressure gauge does not indicate
pressure.
b. Pressure deficiency (partial lack of pressure)
• Desired pressure is not attained. (A);
• Specified nozzle spraying angle is not
attained (B);
• Pressure gauge shows lower pressure (C).
c. Pressure oscillation
• The pressure gauge needle oscillates (D);
• The nozzle spraying angle oscillates (E).
d. Intermittent pressure
• The pressure gauge needle vibrates
with intensity (F);
• The pressure hoses vibrate with in-
tensity;
