Handling 

 

    Warning

 

(1) When connecting the plug, hold the plug securely. 

The plug may be disconnected due to the reaction force of the connection. 

(2) To connect the plug, push it firmly into the socket until it clicks into place. 

After connecting the plug, pull it gently to confirm that it will not come out from the socket. If it 

is not connected firmly, the plug can pop out under pressure. Do not touch the sleeve until it is 

confirmed that the plug has been inserted firmly. Otherwise, it may cause malfunction.   

(3) The plug should be upright to the socket when connected.

 

 

Inclined connection can damage the plug and socket, or cause malfunction. 

(4) When disconnecting the plug, hold the plug securely. 

The connected pipings may move due to the reaction force during disconnection or the residual 

pressure on the plug side. 

(5) The sleeve should be upright to the socket when it is moved. 

Rotating in the circumferential direction can cause malfunction. 

(6) Do not push the inside of the socket with a non-compatible plug, or with any type of stick.

 

 

Otherwise, the fluid can jet out and cause danger. Also, the seals can pop out along with the jet 

of fluid, which can break the product. 

(7) If foreign matter adheres to the plug O-ring, wipe it off. 

If the air blow is performed with the air gun air outlet close to the plug O-ring, the Plug O-ring 

may come off. 

(8) If the plug and socket are unable to separate due to a malfunction in the sleeve, do not 

forcefully pull out the plug. View the sleeve from the insertion side of the plug and turn the 

sleeve 3-5 turns clockwise. Then, check that the sleeve works properly. 

If the sleeve still malfunctions, turn the sleeve counterclockwise for 3 to 5 times.   

If the problem is still not solved, loosen the connecting screw for the plug and socket and 

remove the sleeve from the piping.
