Thread around check spring on techsew 4800

[nikpalmer]

Does anyone have a clear video of the thread around the check spring area during a full stitch cycle. That’s on a 4800 techsew or Juki version. 
My machine is sewing well but from when the needle starts to penetrate the leather to when the needle leaves the leather the thread is slack between the check spring and the take up lever. I dont think that’s how that should be, but I’m not sure and can’t find a clear video.

 

thanks for help

Here's a thread about the check spring, 5th post down has a video that might help.

thanks, I had read that but there is no clear image of how much slack thread is around.  It's no big deal as the machine is running fine, just something I haven't been able to find definitive info on.

 

thanks
