Moved your post to Leather Sewing Machines. This is where the machine guys hang out so you are more likely get an answer here. A picture of your machine may help. Reduce the file size so it can fit the restrictions here. 800 pixels in the longest dimension.

Oils like 3-in-1 and other hardware store oils typically contain waxes and other junk that harden and form a varnish on the lubricated surfaces. This has caused many sewing machines to seize up. You can search this forum and find posts about it. Even happens on furnace fan motors that have run for years with no oiling, suddenly seize up a few months after being oiled with 3-in-1 oil. Quaker State is an example of automotive oils with a high wax content. My old Ford would start running rough, getting to the point it would barely run. I had to pour STP gasoline treatment through the carburetor while running at high RPM to loosen up the sticky valve stems and it would run fine for a period of time. One day my Dad, a professional mechanic, asked what oil I was using. Told him and he said to switch oil to another brand as QS had lots of wax and that was causing the problem. Switched to a different brand, lower wax or no wax content and had no further problems. Beware of oils that have high wax content or additives that cause a build up of varnish for all your equipment, sewing machines plus ...

Not true! As a moderator, I check lots of posts and have advised many members the resolution they should post at. It works. This is what happens with some of the small photos you posted when viewed using Windows 11 Pro and Firefox browser.

Most of your pictures are too small to see detail. You should resize your photos to 800 pixels in the longest dimension. That will provide good detail, fill most screens, and be small files so you can still post all these files in one post.

@Mattpa72 What's the info on the tag, need that to be able to find more information. When you post that, somebody may be able to help. Moved your post to "Shoes, Boots, Sandals and Moccassins"

Moved your post to leather sewing machines, you'll get more response here, this is where the machine guys hang out.

You really should start a new request. Tagging onto an old thread doesn't get a lot of attention.

Translated: Good morning, I recently purchased a Durkopp Adler 69 and while studying how it works I came across the adjustment of the pressure of the feet; I know that the larger threaded part is used to adjust the pressure of the feet but, despite my attempts, I can't understand what the small screw at the top (circled in red) is for, so I'll ask you. @GIULIO English is the language for this site. Please comply.

Moved to sewing leather. If you haven't checked out this thread, take a look at it.

So the controller box has a problem - probably the fuse as you noted. If you have a voltmeter you can check to see what sort of voltage is present if you can access the contacts (both sides). If one side is line voltage, that would say to me, fuse is missing.

Moved your post to "wanted" since it's not for sale.

Much easier for my eyes to read. Better contrast!

Suggest you join Leatherworker.net. This help wanted forum requires approval of nearly all posts. And you would have access to post in all forums.

Good memory! I'm sure you are right about different suppliers. When cutting MDF with a circular saw, I've seen sparks fly. I would suppose that it may be from whatever grinders they are using, or some scrap that gets picked up from truck boxes, loader blades, or whatever during handling.

Always ears up like the stamp

I've seen bits of metal embedded in MDF. Fine for stropping since you're not cutting into it, really smooth.

It would be nice to get his feedback. He/she hasn't been back here since Dec 11. So I suppose we won't get any more info from the OP. @hamim

My first impression was a wolf. Don't know how I arrived at that!

Depending on how you are cutting, sometimes the knife wants to follow the wood grain. Self healing cutting mats are nice as they are all marked out in measured squares making it easier to layout and cut straight lines with a guide rule.

I don't see where you don't understand that I moved your post to Leather Sewing Machines. Home > Fabrication > Leather Sewing Machines It seems to appear from your post that you have visited this forum.

If your files are too large to post here due to file size restrictions, you need to resize your files to fit. Follow this link for some helps and suggestions. https://leatherworker.net/forum/topic/15122-how-to-post-pictures-on-lw/?do=findComment&comment=551171 There are lots of Apps, software, and online tools available on the web, or even built into your device to enable you to reduce your file sizes. 800 pixels in the longest dimension is quite adequate. Smart phone screens and many monitors don't display high res files in high resolution. People that live on the fringes of the internet appreciate smaller file sizes and high res photos may take from 10 minutes to hours to download.
