Pump Troubleshooting
This chart uses proportioning fluid gauges to determine pump malfunctions. Observe the gauge readings during the
stroke direction indicated by the bold arrow, and immediately after closing the gun or mix manifold. Refer to other
manuals to troubleshoot individual components.
Fluid outlet pressure gauges split
only at the top changeover (if one
gauge drops the other will rise).
Not fully loading one side on
upstroke.
Increase feed pressure on side that
dropped.
Increase feed hose size.
Clean inlet strainer or hopper screen.
Air mixed in fluid from excessive agi-
tation or circulation.
Flush and add new fluid.
