After assembly, check the vacuum
levels.
1. On the YG100RA, change the nozzle of
each FNC head to Type 213F, while leave
nozzles detached from the standard
heads. On the YG100RB, leave nozzles
detached from the precision heads.
2. Open the [Unit]-[Head] tab screen and
press the [Vacuum] button to generate a
negative pressure. Read the "Max" values
shown in red on the screen and
determine whether the vacuum levels
are appropriate by referring to the table
below.

FNC head with Type 213F
nozzle
If the "Max" value is less than 100 while the nozzle is open, the vacuum level is
normal.
If the "Max" value is more than 170 while the nozzle is sealed, the vacuum level is
normal.

head without nozzle
If the "Max" value is less than 80 while open, the vacuum level is normal.
If the "Max" value is more than 180 while sealed, the vacuum level is normal.
* The vacuum level in the spline shaft air path might sometimes differ slightly depending on the air source and
operating conditions. Use the above criteria values for reference during maintenance.
