zender Posted July 13, 2019 Report Share Posted July 13, 2019 Hello, I have problem with my Bosch PSR 300 LI, sometimes it working normally, and sometimes it is ''whistling'' like in this video : www.youtube.com/watch?v=BpHBJGYIQZs Is this some kind of electronics problem in it, or what kind of fault is this, can it be fixed ? Thanks. Quote Link to comment Share on other sites More sharing options...
