General Notes For Field Operation
1. Lubricate the sprayer as needed. See “Lubrication”
on page 50.
2. Hitch the sprayer to the tractor, making all electrical,
hydraulic and (if applicable) PTO connections. See
“Hitching Tractor to Sprayer” on page 12.
3. Make sure that the hand wash tank is full of clean
water. Have soap available to clean any contami-
nated areas. ALWAYS wear personal safety equip-
ment as shown at “Wear Protective Equipment” on
page 2.
4. Check and clean, if necessary, pump, nozzles and
Whirlfilters®.
5. Check the sprayer initially and periodically for loose
bolts, pins and hose clamps. Check the hoses,
pumps, valves and fittings for leaks.
6. When transporting the sprayer,
DO NOT exceed 20 mph and
DO NOT transport with chemical in the tank.
7. NEVER allow anyone to ride on the sprayer.
At the Field
8. Make sure all tank shut off valves are turned on.
9. Calibrate sprayer with water only, not chemical and
water. Calibrate with the sprayer tank half full of
water. Refer to the calibration procedures in the
Application Guide.
IMPORTANT !
Make sure to read the label on the chemical com-
pound that is to be applied. It is the law.
10. Consider how the chemical will be stored and how
you will dispose of the chemical, according to the
chemical label.
11. When calibrating, filling the tank, or working around
chemicals, wear protective clothing that covers the
body. See “Wear Protective Equipment” on page 2.
Never open a container with your bare hands.
12. When filling the sprayer, it is better to mix the chemi-
cal in the field where it is to be applied. Position the
sprayer 100 feet from any well or other water source
before mixing the chemical.
13. Safely and carefully add the chemical to the sprayer
tank. By law rinsing of the used chemical container
must be repeated three times. The container should
then be punctured to prevent future use. An alterna-
tive is to jet-rinse or pressure rinse the container.
When adding chemical, remain at least 100 feet from
any water well or fresh water source. Follow chemi-
cal manufacturer’s recommendations for safe han-
dling of chemicals.
14. Adjust throttling valves on the boom valves, and the
manual pressure adjustment valve (if applicable).
Adjust the boom height required for the nozzles and
spacing to be used. (Refer to nozzle tables in the
Application Guide.)
15. Note nearby crops, houses, gardens, people, etc.
16. Apply spray when the wind is 5 mph/8 kph or less to
minimize drift. Use nozzle tips with the largest practi-
cal openings. Operate the sprayer boom at the low-
est practical height and lowest practical pressure.
17. If possible, work crosswise to the wind, starting from
the downwind side of the field. This will prevent
heading directly into the chemical fumes.
18. Drive at the same speed used for calibration. Refer
to Application Guide. Keep your sprayer calibrated.
19. 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.
20. Check the sprayer initially and periodically for loose
bolts, pins and hose clamps. Check the hoses,
pumps, valves and fittings for leaks.
21. Check the condition of hoses and connections fre-
quently. Release system pressure before working on
the sprayer by shutting off the pump and the individ-
ual boom section switches. Always wear rubber
gloves when making repairs or adjustments.
22. 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 throttling
valves. Properly store the chemical emptied from the
tank or dispose of it per label recommendations.

CAUTION
Read and follow chemical manufacturer’s instructions. Some
chemicals and cause serious burns, lung damage and even
death.
