Agitation Before Resuming a Spray Job (Manual Version)

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".
2. Turn the pressure SmartValve towards "Pressure
draining/TurboFiller".
3. Turn the agitation valve towards "Agitation".
€
DANGER! Before turning the pressure SmartValve to "Pressure
draining/TurboFiller" it is very important to be sure that the quick
coupler lid is correct and completely fitted to the filling stud into
its locked position. Failure to do so may cause risk of
contamination and injury from quick coupler lid being "shot" off
when pressurized! If not possible to fit the lid completely,
lubricate the rubber seal and the grip hooks.
4. Engage the pump and set PTO speed to max. 540 RPM or 1000 RPM (depending on pump model).
5. Agitation has started and should be continued for at least 10 minutes.
6. The spray job can now be resumed. Turn pressure SmartValve
towards "Spraying" and start spraying.
