5) Installs the solenoid valve set on the forearm upside.
(standard/internal wiring and piping specification common)
Installs the solenoid valve set instead of the No.2 arm cover U removed above.
When you install the solenoid valve set, be careful to not put the cable and air hose
between the cover and arm and do not break the air hose.
If the cable is inserted, it will become the cause that the cable be broken. And, if the
air hose is put or it breaks, it becomes the cause that the solenoid valve operation is
abnormal.
Confirms having inserted neither the cable nor the air hose and that the air hose has not broken, and fix the
No.2 arm cover U securely by the original fixing screws (Tightening torque: 1.39-1.89N ・ m). Confirms that the air
hose has not broken by removing the No.2 arm cover L.
6) Connect the tool prepared by the customer with solenoid valve port A and B.
(standard/internal wiring and piping
specification common)
Install plugs to the port A/B couplings that are not used for the solenoid valve set. Please prepare the air
hoses and plugs to use by customer.
