Transfer Vacuum Actuator

1. INSPECT ACTUATOR HOSE CONNECTION
Check that the actuator hoses are connected to the solenoids and actuator tightly and properly.




2. INSPECT ACTUATOR AIRTIGHTNESS
(Vacuum Tank)
a. Disconnect the No.1, No.3 and No.4 hoses from the solenoids.
b. Plug the No.3 hose.
c. Connect the vacuum tool to the No.1 hose.
d. Check that the indicator remains stable when a vacuum of 500 mmHg (19.69 in.Hg. 66.7 kPa) is applied.




(No.1 Vacuum Chamber Side)
a. Disconnect the No.2 and No.4 hoses from the solenoids.
b. Connect the vacuum tool to the No.2 hose.
c. Check that the indicator remains stable when a vacuum of 500 mmHg (19.69 in.Hg, 66.7 kPa) is applied.




(No.2 Vacuum Chamber Side)
a. Disconnect the all hoses from the solenoids.
b. Plug the No.3 hose.
c. Connect the vacuum tool to No.1 and No.4 hoses.
d. Check that the indicator remains stable when a vacuum of 500 mmHg (19.69 in.Hg 66.7 kPa) is applied.
