4 - Sprayer Setup

BoomPrime Adjustment

The BoomPrime system works within a fixed pressure range of around 3 bar, but it must be adjusted for the specific spray
job (due to different choice of nozzles etc.):
1. Unfold the spray boom and start the PTO.
2. Set pressure alve to "Spraying", suction valve to "Main tank" and agitation valve to "Agitation".
3. Adjust the spray pressure to what will be used when spraying.
4. Turn the BoomPrime adjustment screw (A) to increase the
BoomPrime pressure to 3 bar or until the nozzles start to leak.
5. If nozzles leak, then lower the BoomPrime pressure by 1 bar on the
adjustment screw (A).
μ
ATTENTION! If not adjusted correctly, the nozzles will not close
(i.e. they will leak), when the spraying is stopped, or the tubes will
not be primed.
The possible priming circulation speed of BoomPrime relies on the non-
drip valves to keep the nozzles closed. For this boom, the blue valves will
open at a spray pressure of 0.8 - 0.9 bar.
