Moved your post to Leather Sewing Machines.  More likely to get an answer here.  Can you provide more information to help solve your problem?

Have you checked your needle for damage, is it threaded correctly?  Was it working fine then suddenly quit, any noise, did it jam or lock up?

Safety clutch out?

No everything fine

1) Check first the obvious part as it is written above:

 - is threading right, is thread moving through the needle, check threading through every single part, i.e. tensions disks, check spring assembly etc.

- check the needle, is it bent or damaged

2) is the upper thread going around the hook?

3) check the needle position to hook and hook timing, I suggest using the old adjustment manual for Pfaff 1245 (the successor of 545), needle and hook timing is described in point 5, but I suggest going through everything:

I merged this post back into your existing thread.  There is no need to start a new thread with the same question.  All it does is cause more clutter on the forum.  If you continue to behave like this, you will be put under moderation.  All your posts would then require moderator's approval before they can be seen by members.

Ok thanks. I just don’t know how to use it properly

Is there any bobbin thread left on the bobbin spool ?

Has the bobbin thread looped over and then under the hook and now is jamming ?

Here's a link to a video from Uwe, it's been mentioned in prior threads about the Pfaff 525 and the safety clutch.
