equipment preparation instructions in the applicator product manual.
CAUTION: Installing swirl nozzles upside down deforms the disk and
prevents the bead from forming a spiral. If a deformed swirl nozzle is then
correctly installed, adhesive may leak into the nozzle air section or an
abnormal pattern may be produced.
6. Reinstall the nozzle and retaining nut. Ensure that swirl nozzles are
correctly placed with the pointed side down. Torque the retaining nut to
20‐25 in‐lb.
