Need help with Juki 1508NH

[Theworks001]

I have a Juki 1508NH but it didn’t come with the knee lift attachment. After installing the attachment, I noticed the knee lift would only raise the feet about 4mm, although it would still drop the hand lift.

 

I tried making a few adjustments on the bottom of the machine using the engineer’s manual. Now the knee lift goes up the same height as the hand lift (but I believe it should actually raise higher than the hand lift). The problem now is that the knee lift no longer drops the hand lift at all.

 

Has anyone run into this issue before? Any guidance or suggestions would be much appreciated.

Try pressing down (with your hand) on the bar that the knee lift pulls down on. Press all the way till you feel it stop against something. How far do the presser feet raise in this case?
