Hi everyone I am sheerwin from Iran. Recently, a friend gave me a VILHELEM PEDERSEN leather splitter machine. It’s very old and needs restoration I searched the internet, but I couldn’t find anything useful. So, can anyone help me about this? What type of motor should I use? Or what kind of oil should be used. tnks every one. photo 01 photo 02 photo 03

Hi all, I was doing some spring cleaning/maintenance on my Cowboy 4500 today. I got everything dusted and cleaned, back on, put together, and oiled. I turned it on to test without a needle/thread installed and it ran great, the only problem is it runs so great that it runs even when I'm NOT pressing on the foot pedal. I don't think I changed anything, but I suppose it's possible I may have bumped or adjusted something unknowingly while moving the machine. -I can push lightly (about half way) on the pedal and the machine will work normally with the speed reducer function. When I let off the foot pedal, the machine will stop as expected. ***The problem comes when I push all the way down on the foot pedal and then let off, the machine keeps running (needle, feed dogs, foot moving etc.) like it's on the slowest setting. It also makes a fairly obnoxious squealing noise while moving very slowly. I tried moving the link on the chain up and down to change the amount of slack and tension- that doesn't seem to be it. If it's too tight it will run too fast and I don't get the speed reduction. Too loose and it doesn't matter. I even had the chain completely unhooked from the pedal and it kept running. I've narrowed it down (I think) to the black plastic arm on the servo motor that is attached to the foot pedal by the chain. It's not going all the way back up to stop the movement of the machine. I can gently push up on it momentarily with a finger and the machine will stop normally. If I let off the pressure with my finger, it will keep running. I also can apply a little more pressure and the whole black plastic arm will "click" or "snap" back up to a locked position and the machine will remain off. It will start up and run normally when I press the foot pedal, but again when I put it all the way down and release it will not stop completely. I have to manually push this arm up to stop it completely. Again, that's why I thought it might be the chain tension, but had not luck when moving the link and tension. Is there anything you can think of that would fix this? What could I have done to cause it? Could the problem be coming from something else? This machine is only 2 years old, hasn't seen excessive use, and it is well taken care of. I bought it from Toledo Sewing Machine and have never had any problems with it before. I'm really hoping I don't have to replace the motor since it's so new. I took the cover off the servo motor to see if there was anything obviously wrong and couldn't see anything. I'm not super mechanically inclined, so I thought I'd start here with the experts before doing anything. I didn't want to start chasing one problem and create a handful of others. Any help you all could provide would be greatly appreciated. Fingers crossed it is something simple and I can get it back to normal. Thanks in advance, -Hannah
