7) Connect the φ4 secondary piping air hoses.
(only internal wiring and piping specification)
Connect the φ4 secondary piping air hoses to the couplings on the back side of the solenoid valve.
Connect the air hoses sequentially from No.1.
The numbers (No.1 to No.4) indicated on the φ4 secondary piping air hoses are consistent with the num
-
bers of piping pulled out of the mechanical interface. Refer to the numbers for piping to the tool.
As an example of the tools,
shows the relation between hand condition and coupling port
number.
