BoomPrime Adjustment
The BoomPrime system (optional) works within a fixed pressure range of around 3 bar, but it must be adjusted for the specific
spray job (different choice of nozzles etc.):
1. Unfold the boom and start the PTO.
2. Set pressure valve 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 adjuster 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
adjuster screw (A).
μ
ATTENTION! If not adjusted correctly, nozzles will not close (i.e.
will leak) when the spraying is stopped or it will not prime the
tubes.
The possible priming circulation speed of BoomPrime relies on the non-
drip valves to keep the nozzles closed. If an extended amount circulation
may be necessary, the non-drip valves can be changed to a version with
higher pressure setting (later opening time).
