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 valve to "Spraying", suction valve to "Main tank" and agitation valve to "Agitation".
Only open the agitation valve to suit the tank contents, e.g. half open.
3. Adjust the spray pressure to what will be used when spraying.
Close all nozzles.
4. Turn the BoomPrime adjustment screw (A) to increase the
BoomPrime pressure to 3 bar or until the nozzles start to drip.
5. If nozzles leak, then lower the BoomPrime pressure by 1 bar on the
adjustment screw (A).
ATTENTION! If not adjusted correctly, the nozzles will not close
(i.e. they will drip), 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. If an extended amount of
circulation is necessary, the non-drip valves can be changed to a version
with higher pressure setting (later opening time).
