•
Rectifier or motor for open or grounded circuit
•
Locked drive assembly

•
Restriction (kinks) in inlet/outlet tubes
•

Check:
•
Air trapped in outlet line or pump head
•
Correct voltage to pump
•
Debris in pump inlet/outlet valves
•
Loose drive assembly or pump head screws

Spray & Pump FAQs —
--Why does the pump not run all the time?
This is a demand pump and only runs with flow; spray wand, by-pass, spray tips or leak in system
--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, slightly open the by-pass valve.
--My pump quit and will not restart - what should I check?
Check all electrical connections. Ensure switch is in the on position. Check in-line fuse and/or fuse in car adapter end. Ensure
correct v/- 10%. 12-13 volt
--Low flow or no flow at all - what should I check?
Check for a clogged suction hose and/or suction strainer. Often you will need to clean the suction strainer. Check for proper voltage.
--Is there a fuse for the sprayer?
Yes, either an in-line fuse, a fuse located in the car adapter housing or both.
--What size fuse should I use as a replacement?
7.5 amp
--What is the range of the spray wand?
35 feet max
--How should I clean the tank after use?
Tank should be cleaned with Nutrasol® or similar tank cleaning agent, and then rinsed with water.
--How do I remove / replace fuse?
Unscrew in-line fuse connector, or unscrew the car adapter housing.
--Can the spray tip on the wand be replaced with a different type of tip?
Yes, however your wand comes with a #18 tip which is standard. Brass tips generally produce better spray patterns than plastic.
--Each time I turn on the pump my fuse blows.
1) Excessive voltage 2) Improper adjustment of the pressure switch 3) Damaged wiring harness.
--What is the warranty (time duration) on pump, tank, trailer pieces, and accessories?
2 years as stated in operation instructions.
WARNING - Ensure the wiring harness does not become pinched or damaged in any way. This may damage the pump or cause
the wiring harness to overheat, resulting in a melt down or fire.
