CAUTION
When the nozzle is not subject to the nozzle shaft blow, the nozzle may collide with the air-blow station, causing
breakage. Before starting the nozzle shaft blow, be sure to check that the set nozzles meet the installed nozzles.

Safety checks
The nozzle shaft blow function also contains the following safety checks.
• Nozzle shaft blow interruption alarm
The head immediately rises if operation stops during nozzle shaft blow due to emergency stop or an interlock triggering.
If the head rises but the air blow still continues, then the nozzle might come loose from the head. To prevent this, a
confirmation dialog box appears if the machine operation stopped during nozzle shaft blow.
• Nozzle sensors to check whether a nozzle is left on the blow station
The nozzle shaft blow function forces high-pressure air through the nozzles during cleaning, so the nozzles might come
loose from the head if machine operation stops during nozzle blow. If a nozzle comes loose from the head and remains
on the blow station while the automatic operation still continues, then the nozzle left on the blow station might interfere
with other heads or with the multi-max unit. Instead of nozzle detection sensor, this machine uses a vacuum pump
flowrate sensor to check for missing nozzles.
This check occurs at Z-axis UP completion following a shaft air-blow operation.
If a missing nozzle is detected, an error displays and all axes are stopped.
