of the crop being harvested. This manual will take you through the steps of operation for the applicator and
also point out safety precautions to follow while using the applicator. Please read this manual carefully to learn
how to operate the equipment correctly. Failure to do this can result in personal injury or equipment
malfunction. If you are unsure about operating the system after consulting this manual, contact your local
authorized dealership for additional assistance. If you are in need of parts for the system please see your
Installation Manual and contact your local authorized dealer to order the parts. This applicator is designed to
apply Harvest Tec buffered propionic acid.
