SPRAY & PUMP FAQs
• Why does the pump not run all the time?
This is a demand pump and only runs with flow
through the spray wand, by-pass valve, or spray
boom nozzles.
• Why does the pump surge while using the
spray wand?
Low flow may cause the pump to surge (or cycle).
This could happen when the spray wand is adjusted
for a small or fine spray pattern. To overcome this,
slightly open the bypass valve on the pump manifold.
• How do I adjust the pressure?
Operating pressure should be adjusted by regulating
the bypass valve. (See full instructions in the
Operation section.)
To adjust the pump OFF pressure setting, see full
instructions under "Adjusting the Pressure Switch" in
the Pump Specifications & Information section.
• Can the spray tip on the wand be replaced with
a different type of tip?
Your wand comes with a #18 tip. It may be replaced
by other types of tip. Brass tips generally produce
better spray patterns than plastic.
