Installing the solenoid valve set 3-71
5) Cut the φ6 primary piping air hoses.
(standard/internal wiring and piping specification common)
To facilitate connection to the solenoid valve, measure the length of φ6 primary piping air hoses (AIR IN
and RETURN) from the end of rubber sheet at the base of the air hoses before cutting
6) Attach the elbow coupling and check the positions for connection.
(standard/internal wiring and piping
specification common)
a) Attach the elbow couplings which attached the solenoid valve set to the φ6 primary piping air hoses (one
for AIR IN, two for RETURN).
b) Check the position for connecting the couplings.
Measure the dimensions from the end of machined surface which install the solenoid valve to the end of
elbow coupling.
If the Length of an air hose is unsuitable, please cut again and adjust.

Take sufficient care to prevent for

eign matters (cut chips of air hoses,
etc.) from entering the robot.
CAUTION
Attach the elbow couplings to the AIR IN
(white) and RETURN (black) air hoses.
Two elbow couplings are made to connect
with the air hose of RETURN (black) to a

*1) To facilitate connection to the sole
-
noid valve, attach the elbow couplings
to face upward.
*2) Before measuring the dimensions,
press the elbow couplings against the
No.2 arm cover L side end face. Also,
check that the air hoses are not bent
in the area specified in the figure.
