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.
