Stroke Volume Control Switch – Increases or decreases the number of strokes per minute of the pump.

Accumulator Pressure Gauge – This gauge monitors the internal pressure of the Accumulator tank. Normal internal pressure should read approximately 1750 PSI during pumping.

Main Pressure Gauge – This gauge monitors the system pressure while pumping material.The maximum pressure rating is 4400 PSI ± 50.

The rightmost position (JOG) changes the pump from automatic to manual cycling.This allows the cylinders to be manually cycled using the Manual Cylinder Jogging Switch.

Manual Cylinder Jogging Switch – This 2-position switch allows the operator to manually jog the cylinders to assist in clearing material line packs and is used to test pumping pressure (See Initial Start-up Procedure section of this manual for testing procedure).
