Agitation Before Resuming a Spray Job
If a spray job has been interrupted for a while, severe sedimentation may
occur depending on the chemicals being used. Before resuming the
spray job, it might be necessary to agitate sediment material.
1. Turn the handle at the suction valve towards “Suction from main
tank”. Turn the pressure valve to closed position and turn the
agitation valve towards “Agitation”. Other valves are closed.
2. Engage the pump and set PTO speed to 540 rpm.
3. Agitation has started and should be continued for at least 10
minutes.
€
The spray job can now be resumed. Turn pressure valve towards
“Spraying” and start spraying.
Parking the Sprayer
To avoid spot contamination, the sprayer should always be parked at either the washing/filling location or under roof.
This prevents rainfall from washing down chemical residues from the sprayer's surfaces.
• Parking at the washing/filling location will retain residues.
• Always park the machine out of reach of children, animals and unauthorized persons.
BoomPrime
The BoomPrime system works automatically, and it is activated, when a spray job is prepared:
1. Unfold the boom and turn on the PTO.
2. Set pressure valve to “Spraying”, suction valve to “Main tank” and
agitation valve to “Agitation”, if needed.
3. Adjust the spray pressure to what will be used when spraying.
4. The boom will then be fully primed within 1-2 minutes.
If the nozzles start to leak, when closing one or more sections during a
spray job, proceed as follows:
1. Adjust the pressure on the BoomPrime pressure regulation.
2. Turn pressure valve to “Main tank”.
3. Disconnect the PTO.
If adjustment of the BoomPrime system might be necessary, please refer to “BoomPrime Adjustment” on page 42.
