Operation
Note:
Agitation is not meant to be used while
spraying. Shut off the agitation to ensure proper
spray pressure and distribution. There is some
agitation even with the agitation in the “OFF”
position.
6. Use the spray pressure control switch to adjust
the pressure. The red and white nozzles installed
on this machine have a normal operating pressure
of 40 psi (2.8 bar).
7. Using a container marked in ounces, catch the
output from each nozzle for 19.7 seconds. Write
down the number of ounces from each nozzle.
Note:
Repeat the test three times and average
the nozzles separately.
8. Turn off the pump/tank agitation switch.
9. For example purposes, the amount collected is
shown below:
Nozzle Color and
Location
Amount Collected Per
Nozzle (in 19.7 seconds)
Red — Narrow Spray
Center Nozzle 16.75 fl oz (.49 L)
White — Wide Spray
Right Nozzle 33.5 fl oz (.99 L)
White — Wide Spray
Left Nozzle 33.5 fl oz (.99 L)
10. Convert the fluid ounces collected for the right
white nozzle to gallons.
Note:
1 Gallon = 128 fluid ounces (fl oz)
33.5 fl oz
128 fl oz
= .26 Gallon
11. To determine the current capacity of the right
white nozzle, convert .26 Gallons in 19.7 seconds
to gallons per minute (GPM):
.26 Gallons x 60 seconds
19.7 seconds
=
.79 gpm
(3.0 L/min)

website to determine if the amount collected is

Note:
The chart capacity information is based
on water being sprayed at 70
°
F (21
°
C).
13. Perform steps 10 through 12 on each nozzle.
Note:
If the collected nozzle spray does not
meet the charted amount, check the nozzles,
hoses, and fittings for leaks or damage; clean or
replace if needed.
Determining Application Rate
Use the example results of the calculated speed,
spray width, and nozzle capacity to determine the
application rate.
Note:
The application rate may also be determined
by using the TeeJet

chart referenced above, along with the chemical
manufacturer’s label of recommendation.
