SPRAYER CALIBRATION, ADJUSTMENT, AND OPERATION (continued)
2. Place a catch receptacle in position to catch the entire spray pattern from the nozzle to be
checked. Pull the spray lever to begin spraying. Spray for one minute, collecting the
nozzle output.
3. Measure the collected water.
a. Output from the high gear broadcast nozzle (TF-VS5-Blue Band) must be 90 ±
9 ounces (2.7 ± 0.27 liters).
b. Output from the low gear broadcast nozzle (TF-VS3-grey band) must be 66 ± 7
ounces (2 ± 0.2 liters).
c. Output from the high gear trim nozzle (ULD120-03-blue) must be 39 ± 4
ounces (1.2 ± 0.12 liters).
d. Output from the low gear trim nozzle (ULD120-02-yellow) must be 28 ± 3
ounces (828 ± 83 milliliters).
4. If the output from a nozzle is significantly outside the limits, refer to Section 4, FAULT
ISOLATION.
The Sprayer requires periodic calibration and adjustment to verify the sprayer patterns
and to verify the correct product delivery rates
.
Whenever you change products or
rates of application and at one-month intervals, or more frequently during heavy use,
verify that calibration is still valid. Adjust as necessary.
Calculating the Spray Mix Rate
The machine is designed to spray evenly by overlapping only 1.5 to 2 feet of the edge of the
last spray pass. The effective spray width is 7 feet, which is exactly the same as the fertilizer
effective material spread width of 7 feet.
Before handling, mixing, or applying any pesticides, read and follow product
label and material safety data sheet. Some materials may present health
hazards and will require protective clothing and/or breathing equipment.
Follow product label and MSDS disposal instructions and any local
regulations that apply to the product
1. Calculate the time needed to treat 1000 square feet.
a. Measure a distance of 143 feet (44 meters) over turf. This will provide a spread area
of approximately 1,000 ft
2
(93 m
2
). The effective spray width is 7 feet; therefore, 7 x
143 = 1,001 ft
2
(93 m
2
).
b. With the machine in neutral run the engine at full throttle. Check the tachometer to
make sure the engine is running at 3450 rpm. Once we know that the engine is
