Hello, I would like to have your help. I've just bought a brand news wise 2086 engine and mouted it on my Pro's pro challenger 2. I strung a first racket yesterday without any problem (BG66 at 11kg). I tried to string a racket with BG66UM today at 10.5kg (23 lbs) which isn't so big and it's impossible to tension the string. It's slipping through the gripper (or jaw) of the machine. I've tried to adjust the internal screw of the machine and even romoved it but still have the same problem. Do you guys have experiment the same issue with the wise 2086? thank you.
You have to remove the gripper plates and take out the limiter pin on the one on the far jaw - that pin will hit the housing of the screw whether the screw is in place or not.
Thank you all I've found an old thread where mark told to remove the pin. I've managed to do that yesterday and everything is fine now Its really a very good machine
