Select the nozzle position to be measured, and measure.
(Here we start with position 1 as an example.)
8. Turn OFF the vacuum for the nozzle
position that will not be measured
and pos1 to pos6 of the facing head.
∗ Press
UNLOCK
+ for pos 2 to 6.
∗ One vacuum pump is shared with AF and AR,
and another is shared with BF and BR.
9. Lower the nozzle of the position to be
measured.

10. Turn OFF the servo switch.
11. Open the safety cover.
12. Detach the nozzle located at the posi-
tion selected in steps 8 and 9, and
then set the vacuum gauge to the
nozzle holder tip.
∗ If you take a measurement with a nozzle
attached, a vacuum can leak from the joint of
its reflector; therefore, a correct value may not
be measured.
(The vacuum gauge shown on the left is an
example. It is not an attachment.)
13. Check the vacuum pressure.
∗ Ensure that the vacuum pressure is over 80.0
kPa.
The vacuum pressure is not over 80.0 kPa
Check the following items. Inform us if there is no trouble.
1. Checking air leakage in the vacuum pass
• Ensure that no break in the pass. (no sound of air leakage)
2. Checking trouble in the vacuum pump
• Check for strange noise from the vacuum pump.
• Check for waste of parts.
• Check the vacuum pressure of the vacuum pump by the gauge attached to the pump.
14. Take off the vacuum gauge.
15. Close the safety cover.
16. Turn ON the servo switch.
