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 manufac-
turer, 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 func-
tion of the crop protection sprayer.
¾
The prescribed maintenance tasks and legal
regulations on crop protection sprayers must
be complied with. Rectify apparent faults im-
mediately. Have the crop protection sprayer
checked, as requested.
¾
Before starting with spraying check the follow-
ing value on the control terminal:
•
The spraying pressure range defined
on the terminal must agree with the per-
missible 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 combi -
nations 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
[0.007 in] with 80 meshes/inch
2
. This pressure
filter element is adequate for a nozzle size
from 02’.
The pressure filter element with 100 meshes/
inch
2
is required for nozzle sizes ‘015’ and ‘01’
(special 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. Con -
tact 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
Take appropriate action if an error message
appears in the display during spraying oper-
ation.
¾
Check the displayed spraying pressure during
spraying operation.
¾
Make sure that the displayed spraying pres-
sure 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 pro-
tection 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.
