To: @Gamma Tech I have been using a new Gamma X-6FC for more than 3 years without any problem. https://images-na.ssl-images-amazon.com/images/I/81pT7IofTGL._SL1500_.jpg I decided to clean the gripper, not because it is slipping, but because it has been 3 years and 120 rackets strung. I dis-assembled the gripper to clean it. After removing the last screw, some parts pop off (springs and some plastic parts). I cleaned the gripper with isopropyl alcohol (99%) and a tooth-brush. After that, I re-assembled the gripper and put it back to the stringer. I think I did not re-assemble the gripper properly because I notice some string slipping once in a while. Can you send me a diagram on how to dis-assemble/assemble the gripper, especially the positioning of the 2 wire springs and the blue plastic part. Thank you.
