emptying the tank, open the bleeder valve
slightly to expel air and facilitate priming.
As soon as the pump is operating, close the
bleeder valve.

If the spraydown pump has stopped or will not start:
1. Check the effectiveness of the battery power supply
(voltage activity).
2. Check that the fuse has not blown.
3. Check for any foreign material present in the hose.
4. Avoid running the pump dry for more than a few
minutes. (Pumps run dry by the absence of fluid are
not covered by warranty.)
5. If the pump does not prime itself:
• Raise the screed completely, ensuring citrus
tank on the screed is filled.
• Loosen the bleeder valve inside of the cut-out
until the pump primes.
• Retighten the bleeder valve.
NOTE: Change filter as needed.

• Solid green means the pump is spraying.
• Flashing green means the pump is in a stand-by
mode, ready to spray.
Yellow:
• Solid yellow means the pump is priming.
Yellow/ Blue:
• Flashing yellow and blue means the pump has
incorrect voltage.
Red/Blue:
• Flashing red and blue means the pump has timed-out
without fluid. Cycle pump power to reset.

Consult owner’s manual for troubleshooting.
NOTE: If an overload occurs, the pump stops and a
yellow-green LED will flash. The electronic system
will try to reactivate the pump at preset intervals.
If the overload reaches a dangerous level, the red
LED will become solid and you must switch the
power off and start the pump again.
