Precautions:

- The coil shall not be powered on alone, which has the risk of burning!

- The socket, which solenoids used, is according to ISO4400 Standard. There are two specifications: with or without indicator light. You can choose according to your requirements.

- The pushpin of the solenoid is used in adjustment or sometimes in emergency. But when the backpressure of the system is higher, please use screwdriver to push it, not strike it. The wallop can destroy the pushpin and the surface of the leading hole or the solenoid will leak oil or cannot reposition.
