1. When connecting the plug, hold the plug securely. The plug may be uncoupled due to reaction at the time of connection. 2. When connecting the plug, pull out the sleeve straight and insert the plug completely until it stops. After the connection, gently pull the plug to see whether it will release. If not securely inserted, the plug may pop out due to the pressure. 3. When connecting the plug, insert it straight into the socket. If not inserted straight, the socket and/or plug may be damaged or cause a disconnection. 4. When releasing the plug, hold it securely. When releasing the plug, hold it securely. The connection pipe may go out of control due to reacting stress and/or residual pressure on the plug side. 5. Do not press the inside of the socket with an incompatible plug and/or with a tool. The internal fluid may be ejected and cause a dangerous situation. Also, the ejecting internal fluid may cause the sealings to come apart resulting in the product not functioning. 6. Do not connect and remove the coupler when it is pressurized and residual pressure exists. The coupler may fly out. 7. Do not apply lateral load vertically to the connection direction of the plug or socket. This may cause leakage and damage the coupler. 8. Never pressurize when the plug is removed. This may cause the connection piping to flap and be dangerous. 9. When removing the plug, fluid in the piping leaks out. Handle the fluid carefully, especially when using dangerous fluids such as a fluid with high temperature and pressure. The use of a stop valve is recommended. 10. When using a fluid with high temperature, the S coupler will be heated, too. Do not touch the coupler to prevent burning. 11. When sleeve lock mechanism is provided, do not apply pressure when rotating the sleeve. If it is pressurized, the detent of the locked and released position may become unclear due to the pressure. 12. Do not disassemble the S coupler. Handling Warning 11. Do not use in places or environments where foreign matter sticks to the product or gets inside the product. It may cause air leakage or tube release. Operating Environment Warning 1. Maintenance work If handled improperly, compressed air can be dangerous. Assembly, handling, repair and element replacement of pneumatic systems should be performed by qualified personnel only. 2. Drain flushing Remove drainage from air filters regularly. 3. Removal of equipment, and supply/exhaust of compressed air When components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut the supply pressure and power, and exhaust all compressed air from the system using the residual pressure release function. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement. 4. Be absolutely sure to wear safety glasses when conducting periodic inspections. 5. Check for the following during regular maintenance, and replace components as necessary. a) Scratches, gouges, abrasion, corrosion, rust b) Leakage c) Twisting, flattening or distortion of tubes and hoses d) Hardening, deterioration or softening 6. Do not repair or patch the replaced tubing, hoses or couplers for reuse. Do not disassemble the S coupler.
