Preparation for spraying
operation
WARNING
Danger caused by accidental contact with crop
protection agents / spraying mixture!
Wear personal
protective outfit
¾
when preparing the spraying mixture.
¾
when cleaning / replacing spray nozzles.
¾
during all work for cleaning the crop protection
sprayer after spraying operation.
When wearing the required protective
outfit always follow the instructions of the
manufacturer, the product information, the
instructions for use, the safety data sheet or
the operating instructions for the crop protection
agent to be handled.
NOTE
Basic prerequisite for the proper application
of crop protection agents is the proper
function of the crop protection sprayer.
¾
The prescribed maintenance tasks and legal
regulations on crop protection sprayers must
be complied with. Rectify apparent faults
immediately. Have the crop protection sprayer
checked, as requested.
¾
Before starting with spraying check the
following value on the control terminal:
•
The spraying pressure range defined on the
terminal must agree with the permissible
spraying pressure range of the spraying
nozzles installed.
¾
Use all specified filters.
¾
Clean the filters at regular intervals.
Trouble-free operation of the crop protection
sprayer is only ensured with flawless filtration
of the spraying mixture. Appropriate filtering
considerably influences the treatment success
of the crop protection measure.
¾
Pay attention to the permissible filter
combinations or mesh sizes.
The mesh sizes of pressure filters and nozzle
filters must always be smaller than the nozzle
opening of the nozzles used. Notes given by
the manufacturer of the crop protection agent
must be followed.
The standard
pressure filter element used in
the pressure filter has a mesh size of 0.18
mm with 80 meshes/inch. This pressure filter
element is adequate for a nozzle size from 02'.
The pressure filter element with 100 meshes/
inch is required for nozzle sizes '015' and '01'
(optional equipment).
¾
Remember that the use of pressure filter
elements with 100 meshes/inch will have
the effect that with some crop protection
agents active components may be filtered
out. Contact the crop protection agent
manufacturer in the respective case.
¾
Generally clean the crop protection sprayer
before placing a different crop protection
agent.
¾
Flushing nozzle line and nozzles:
•
with each nozzle change
•
before installing other nozzles
•
before turning the manual three-fold / five-
fold nozzle head to another nozzle.
¾
Couple the crop protection sprayer properly
to the tractor (see chapter Connecting/Parking ).
¾
Take appropriate action if an error message
appears in the display during spraying
operation.
¾
Check the displayed spraying pressure during
spraying operation.
¾
Make sure that the displayed spraying
pressure does under no conditions deviate
from the specified spraying pressure from the
spraying table by more than ±25%, e.g. when
changing the application quantity
¾
More significant deviations from the specified
spraying pressure will adversely affect the
optimal treatment success of the crop protection
measure and/or cause environmental damage.
¾
Reduce or increase the travel speed, until the
permissible spraying pressure range (of the
intended spraying pressure) is reached again.
