1. Weekly or biweekly inspection
Inspect and clean the nozzles weekly or biweekly as explained below.
1.1 Cleaning a nozzle
If solder adheres to a nozzle tip, the nozzle may be mistaken for a component or other problems may occur. If
nozzle spring-action is poor or the nozzle tip is nicked, pickup errors tend to occur frequently. To prevent these
troubles, check the nozzle condition and keep the nozzles clean.
1
Remove the nozzle from the head.
e
Always first press the emergency stop button and
then remove the nozzle from the head.
c
CAUTION
When the machine is equipped with a nozzle station, make
sure that the nozzles are returned to the nozzle station.
2
Blow air onto the nozzle tip.
Use an air blow gun to blow air onto the nozzle
tip.

hole and clean the nozzle hole. While holding both
ends of the wire with fingers as shown or using a
custom handle, gently move the nozzle back and
forth.
