C . Ensure correct spray pattern
Make sure both boom nozzles are pointed toward the ground. If they are not,
loosen the nozzle retaining nut, orient the opening of the boom nozzle to point
straight down, then retighten the nozzle retaining nut.
IMPO RTANT: Make sure broadcast nozzles are oriented to spray straight
down before you start. An incorrectly positioned broadcast nozzle may spray
chemicals on you or others.
Note : It is not unusual for the operator to be exposed to chemical drips while
adjusting the broadcast nozzle. Chemical resistant gloves should be worn.
D. Ensure uniform cove rage
To ensure proper coverage, the height of the unfolded boom nozzles should be
about 23” from the ground. The sprayer must be level with the ground to get
this height.
The overall spray width is 120”, but 1/3 or 40” of the overall spray pattern must
be overlapped to get equal coverage throughout the spray area.
Use the tables in Appendix A to determine what speed to drive your vehicle for
