2 Do not tighten up screws on CUPLA in excess of the rated maximum tightening torque. This may cause damage on thread. Do not apply any artificial impact, bend, or tension other than necessary in connection and disconnection. This may cause leakage or damage. Do not use in a place where dust or metal dust may be around. This may cause malfunction or leakage. Use only within the range of rated temperature. Otherwise this may damage the seal material inside and cause leakage. Use Cuplas only for the purpose of quick connective couplings. A shut-off valve must be installed between pressure source and the CUPLA . Do not use as a swivel joint. Direct hookup to a vibration or impact device may result in reduced lifetime. Do not connect/disconnect under dynamic pressure or static residual pressure. There is a small amount of spillage during disconnection. Pay careful attention when handling socket or plug if the fluid is in high temperature or may be hazardous.

3 Do not strike the tip of an automatic shut-off valve with a hammer or the like. This may cause leakage or malfunction. Fluid must be cleaned through filters before reach to Cuplas. O-rings in Cuplas must remain lubricated at all times. If the sleeve of socket does not slide well, apply a small amount of grease GRE-S1 (Silicon base series) on the balls of the socket with your fingers. Grease GRE-S1 (Part ) is available from us as optional maintenance accessory. Always select the right seal and body materials that are suitable for the fluid to be used. Do not connect with other brands quick connective couplings. Do not disassemble. Design and keep the fluid flow speed through Cuplas below 8 m/s for hydraulic use. Check up on Cuplas periodically. If any disorder is shown, stop using the Cuplas until properly repaired or replaced with new ones. After connection, try to pull the plug and socket apart to check secure connection. Incomplete connection may cause accidental disconnection of the socket and plug under dynamic quality of seal materials plays an important role in maintaining the performanceof the ZEROSPILL CUPLA .
