I am facing a problem in my wise head 2086 suddenly my wise head shows an error 1. When i start it the tensioner moves for test but after that it stops and i can't set Tension on it and the Tension switch (the red button behind the tensioner) not work when pressing it .http://cloud.tapatalk.com/s/5a531403ee5d9/VID_20180108_121540.mp4 Sent from my HM NOTE 1W using Tapatalk
