Agitation Before Resuming A Spray Job - Hardi NAVIGATOR 4000 Instruction Book

5 - Operation
μ
ATTENTION! If not flushed with clean water, the hopper rinsing device uses spray liquid for rinsing the hopper!
Cleaning the TurboFiller must always be done, when the spray job is ended, and together with cleaning the entire
sprayer. A cleaning after the last filling, and before spraying, does not ensure a clean TurboFiller!
8. Close TurboFiller suction valve, when the hopper has been rinsed. Close the lid.
9. If closed, turn the AgitationValve towards "Agitation".
10. When the spray liquid is well agitated, turn handle of the
pressure SmartValve towards "Spraying" position. Keep PTO
engaged, so that the spray liquid is continuously agitated, until
it has been sprayed on the crop.

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 alve towards "Pressure Hopper"
and turn the Agitation valve towards "Agitation". Other valves
closed.
2. Engage the pump and set PTO speed to 540 rpm or 1000 rpm
(depending on pump model).
3. Agitation has started and should be continued for at least 10
minutes.
4. The spray job can now be resumed. Turn pressure SmartValve
towards "Spraying" and start spraying.

DANGER! Before turning Pressure SmartValve to "Pressure
Hopper" it is very important to be sure that the quick coupler lid is correct and completely mounted 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 mount lid completely, lubricate the rubber seal and the grip hooks.
