Operating Instructions
Basic Sprayer Operating
Procedures
1. Make sure to read the label on the chemical com-
pound that is to be applied. It is the law.
2. Consider how the chemical will be stored and how
you will dispose of the chemical, according to the
chemical label.
3. When calibrating, filling the tank, or working around
chemicals, wear protective clothing that covers the
body. Refer to "Personal Safety Equipment" on
page 5. Have soap and clean water available to
wash any exposed areas. Never open a container
with your bare hands.
4. When filling the sprayer, it is better to mix the chem-
ical in the field where it is to be applied. Position the
sprayer 100 feet from any well or other water source
BEFORE mixing chemical.
5. By law, you must repeat the rinsing of the chemical
container 3 times. The container should then be
punctured to prevent future use. An alternative is to
jet-rinse or pressure rinse the container.
6. Check the condition of hoses and connections fre-
quently. Release system pressure BEFORE work-
ing on the sprayer by shutting off the pump and
flipping the individual boom section switches on the
control box. ALWAYS wear rubber gloves when
making repairs or adjustments.
7. After unfolding the boom, remove the level float pin
and place in the storage position. Refer to your
Great Plains Boom Manual for more information.
Note: If possible, do not operate your Great Plains
Sprayer Boom without first unlocking the level-float pin.
The boom will float over the contours of the ground more
effectively and minimize stress on the boom.
8. Apply spray when the wind is 5 m.p.h. or less. Mini-
mize drift by using nozzle tips with the largest prac-
tical openings and by operating the sprayer boom at
the lowest practical height and lowest practical pres-
sure.
9. Drive at the same speed you used in your calibra-
tion. Refer to "Sprayer Calibrations" on page 28.
Keep your sprayer calibrated.
10. If possible work crosswise to the wind, starting from
the downwind side of the field. Do this so you won’t
ever be heading directly into chemical fumes.
11. Take note of adjoining crops, houses, gardens, peo-
ple, etc.
12. When you are finished spraying, empty the tank and
flush the sprayer with water, including the pump, the
nozzles and the bypass line from the solenoids.
Properly store the chemical emptied from the tank or
dispose of it by the recommendations on its label.
13. When turning at the end of a field, make sure you
are correct on the rows so that the boom will not
overlap on crop previously sprayed.
