NOTE: Lower pressure settings will result in
less spray drift.
Example:
Assume tractor speed is determined to be 4
mph, nozzles are gray (TFVP3), and desired
GPA is 20 GPA. The calibration charts shows
that you should set sprayer’s pressure at about
20 psi in order to apply 20 GPA.
NOTE: Optimum spray performance is achieved
between 20-25 psi. When shutting off outer tips,
use the regulator valve to adjust your boom
pressure accordingly.

Adjusting the Sprayer Pressure
NOTE: All calibration needs to be done with
clean water.
Once correct pressure setting has been deter-
mined, the sprayer must be adjusted to that
pressure setting. Before adjusting sprayer’s
pressure, it is important to set tractor
rpm at rate that was used to determine tractor
speed.
2.2 gpm pump
Although the pressure can be adjusted by par-
tially opening the control valve (A), it is
recommended that the valve be placed in the
full open position.
• The 10 ft boom is equipped with the TF-VP3
tips and sprays at approximately 20 PSI
through the boom when the valve is in open
position.
• For calibration purposes, adjust your speed
for proper coverage.
4.0 gpm pump
1. Loosen lock ring (B) and adjust knob (C) to
desired pressure. Pressure is displayed on
gauge (D).
2. Once desired pressure is achieved tighten
lock ring (B).
3. Sprayer is now calibrated.
