Recently I was asked how to thread the Elna Contessa 400. As I result I created some diagrams, which I thought might be of use to others so I will share them here.Threading - overviewClose-up of needle threadingIn the top threading images above, the red arrows point to the thread guides and the black line shows the approximate path of the thread. Click on the images to see them and the instructions larger.How to wind a bobbinThe path of the thread for bobbin winding is show in blue. There was actually no bobbin winder on this machine when the image was taken, consequently the grey block that I added is where it should be.The bobbin case of this machine threads as they do on most machines, hold the bobbin case in your left hand, with the open end facing to the right. Hold the bobbin in your right hand with the end of the thread going away from you. Put the bobbin in the bobbin case and pull the thread through the slot in the bobbin case and under the tension spring.
That's the bobbin case threaded.As usual, if you have any questions, drop me a line and I will do my best to answer them! Hi, I am not acquainted with an Elna 460, I had a quick google and they looked rather new, so my information may not be accurate.
Generally speaking, if you can access the bottom of the machine, you should lightly oil most things that move against another surface, paying particular attention to the rotation of the bobbin and motion of the feed. Also on the side of the machine, any points that rotate about a pin or slide on something should be lightly oiled, and the same for under the top cover as well, if you can access that. If the machine has electronics, oiling near them could be a problem, if it has plastic gears, only grease them if it looks like they have previously been greased. Metal gears should be greased. I hope that helps a little.
