needed. See Xtreme Mix Operation man-
ual.
Pump not operating correctly. Observe whether pumps are loading and
checking correctly, if not, clean and repair
pump. See pump manual.
Poor spray pattern. Fluid pressure too low. Increase pump pressure.
Spray tip dirty or worn. Relieve pressure. Clean or replace tip.

Mixer or hoses partially plugged or too
restrictive.
Inspect parts for cured material. Clean or
