| Hi Clough, Thank you for the responce to my question. I found the answer to the question . This knob adjusts the dogs, dogs are the little serations under tha cloth that push the material as the needle pushes the thread and makes the stitch. The d position is for down, the f is the middle position, the r is the highest position.
Now i'm trying to time the machine since the bevel gear that runs the vertical shaft that connects the drive belt that runs the hook under the bobin broke and now is replaced. The timing has to be perfect i'm told so I going on line to find out how to do this. Thank you for your interest. Rich |
