SPRAY & PUMP FAQ
1. Why does the pump not run all the time?
This is an on-demand pump and only runs with flow; spray wand, by-pass, spray tips
or leak in system.
2. 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 ajusted for a small or fine spray pattern. To overcome, slightly open the by-pass
valve or open nozzle slightly.
3. How do I adjust the pressure?
Pressure should be adjusted by regulating the by-pass valve (slightly opening or closing).
4. What is the optimal operating pressure?
40 PSI - This can be accomplished by turning on the pump and adjusting the bypass
valve until the gauge reads 40 PSI (or slightly higher). The pump will run continuously.
Ensure that the boom and/or handgun is not spraying while you set the pressure. The
pressure will drop slightly when the boom and/or handgun is operated.
5. What pressure should the pressure gauge read?
Please refer to the operation instructions for boom operating pressures, varying boom
pressures can be achieved by regulating or adjusting the by-pass valve. Typically the
spray wand will be operated between 20 and 40 PSI.
6. 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 voltage +/- 10%. 12-13 volt
7. 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.
8. Is there a fuse for the sprayer?
Yes, either an in-line fuse, a fuse located in the car adapter housing or both.
9. What size fuse should I use as a replacement?
10 amp
10. What is the range of the spray wand?
35 feet max
11. How should I clean the tank after use?
• Rinse tank thoroughly with water only, empty, refill with water.
• Empty sprayer by spraying no less than 1 minute to rinse out line. The remaining water
can be drained per the drain plug.
• Store sprayer tank upside down, in a warm dry location.
