5. Engage the hopper transfer device by opening the ChemFiller
suction valve (A) to transfer chemicals to the main tank. The
ChemFiller suction valve must be open for at least 20 seconds after
the chemical is no longer visible in the hopper, in order to empty
the transfer hoses completely into the main tank.
€
DANGER! If the ChemFiller and the transfer hoses are not
completely emptied, there is a risk of chemicals being sucked out
of the main tank!
6. If the chemical container is empty, it can be rinsed by the Chemical
Container Cleaning device. Place the container over the multi-hole
nozzle and push the lever (C) container for cleaning.
€
DANGER! In order to avoid spray liquid hitting the operator, do
not press the lever (C), unless the multi-hole nozzle is covered by
a container, as spray liquid may otherwise hit the operator!
μ
ATTENTION! The rinsing device uses spray liquid to rinse
containers for concentrated chemicals. Before disposal, always
rinse the chemical containers with clean water several times, until
they are clean.
7. Flush the ChemFiller with clean water from the rinsing tank by shifting to suction from Rinsing Tank. The ChemFiller
suction valve (A) must be open for at least 20 seconds after the rinse water is no longer visible in the hopper, in order
to empty the transfer hoses completely into the main tank.
μ
ATTENTION! If not flushed with clean water, the hopper rinsing device uses spray liquid for rinsing the hopper!
Cleaning the ChemFiller 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 ChemFiller!
8. Close the ChemFiller suction valve (A), when the hopper has been rinsed. Close the lid.
9. Turn the AgitationValve towards "Agitation".
μ
ATTENTION! If foaming is a problem, turn down the agitation.
10. When the spray liquid is well agitated, turn handle of the pressure
valve towards "Spraying" position. Keep the PTO engaged for
continuous agitation during spraying of the crop.
