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 Wear Protective Equipment on page 5.
Have soap and clean water available to wash any ex-
posed areas. Never open a container with your bare
hands.
4. When filling the sprayer, it is better to mix the chemical
in the field where it is to be applied. Position the spray-
er 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 punc-
tured 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 working 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. Apply spray when the wind is 5 m.p.h. or less. Mini-
mize drift by using nozzle tips with the largest practical
openings and by operating the sprayer boom at the
lowest practical height and lowest practical pressure.
Refer to Figure 7
8. After unfolding the boom, remove the level float pin
and place it in the storage position.
9. Drive at the same speed you used in your calibration.
Refer to Sprayer Calibrations in the Sprayer Owner’s
Manual. 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 by-pass line from the solenoids. Prop-
erly store the chemical emptied from the tank or dis-
pose 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.
Parking
The following list should be followed when you want to un-
hook your boom.
1. Flush the boom out with antifreeze (Great Plains
strongly recommends the use of recreational vehicle
antifreeze) to prevent damage to components when a
freeze occurs.
Refer to Figure 8
2. Lock the level float pin and fold the booms.

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.
