4.7 SPRAYER CALIBRATION
A sprayer can only apply the proper
amount of chemicals when each
component in the system is functioning
properly. Chemical action in the field
is dependent upon the accurate
application of minute amounts of the
spray compound. A complete calibra-
tion of the machine is required at the
start of each season or when changing
chemicals during the spray season.
It is the responsibility of the cus-
tomer to determine the amount of
chemical that they want to apply for
their particular application. Many
factors affect how much chemical is
applied such as: nozzle flow rate,
chemical circuit pressure, pump
speed, ground speed to name a few.
In this section, instructions are
given on how to accurately deter-
mine flow rates or application rates
and how to change them. It is
recommended that this procedure
be followed carefully so you know

4.7.1 ENGINE RPM
Although the exact value of the engine speed is
not particularly important to sprayer function, it is
recommended that it always be set at 2/3 or more
throttle position. This will insure that there will be
sufficient oil flow through the hydraulic system and
sufficient power to maintain the ground speed.
Select the desired engine RPM and always
perform the calibration and run in the field at the
same setting.
exactly how much chemical is being applied.
Work closely with your chemical supplier,
nozzle manufacturer and pest control special-
ists to equip and operate your machine to
obtain the best results. Several nozzle types
are available for the sprayer. Use the type
appropriate for your application.
