NOTE
The nozzle hole of the nozzles marked by asterisk (*) is larger than that of other nozzles. So, if the vacuum levels of a
head using those nozzles marked by asterisk (*) or using no nozzle exceed the above standard values, the air path
(spline shaft, etc.) in the head might be clogged.
n
NOTE
**When the vacuum level does not get 100 or less while nozzle is detached from RS head unit, measure the vacuum
level by detaching the filter.

2. After checking and cleaning the nozzle, reattach the nozzle to the head while making sure the head position and the
nozzle's orientation are correct.
n
Checking nozzles by detaching them from the nozzle station (option)
1. Return all nozzles in the nozzle station.
2. Press the [Nozzle Stn Shutter] button on the [Unit]-[Head] tab screen to be ready for detaching nozzles.
