02 - Check if there was fluctuation in the pressure registered on the pressure gauge (60 psi).
If so, prodeed as follows:
- Loosen the fixing screw.
- Turn the grip clockwise all the
way and then counterclockwise
to set the pessure gauge needle
at 60 psi.
-Tighten the fixing screw.
Take care not to change the
grip position.

MAIN COMPONENTS OF SPRAYER
NOTE: Once the boom section is calibrated, set the lever back.The pressure must be the
same as indicated previously on the pressure gauge (60psi), when this section nozzles are on.
- Repeat the same operation on the other boom sections in order to keep constant pressure
along the entire boom.
ATTENTION: Do not change the engine rotation during the calibration. A change in the rotation
will change the pressure on the nozzles and therefore their flow rate.
CABLE CONTROL AND JSC
To calibrate the pressure on the control with the JSC, the procedures are the same, except
for pressure adjustment, which in this control is not manual but made through an electric
system.
PRESSURE ADJUSTMENT:
- With the pump running at 540 rpm
and the system energized, press the
electric switch until obtaining the
working pressure desired.
For this operation, the
"Automatic/Manual" switch
of the JSC-5000 must be
on the "Manual" position.
- To calibrate the boom sections, proceed as described above.
