This is a great invention that has made it into the mainstream. Using your knee, you can lift the
presser foot or drop it at the beginning of a seam. Combined with the needle-stop down, you
can easily pivot when topstitching or appliquéing. This is a real time-saver. Some of these
systems are mechanical, and some have an electronic assist.
One style drops the feed dogs when you activate it. This, combined with the extra lift, makes it easy to slip bulky fabric under the foot. The feed dogs reengage on the next stitch.
If you sewed in the past with a machine that had its speed controlled with a knee lever, the lifter
might take a little getting used to, but it is worth it!
One thing to remember is that when you lift the foot with the knee lift, it also separates the tension discs for you. This means that if you inadvertently rest your leg on the lever as you are
sewing, you may get loops on the back of your fabric.
Bernina 930 Record; Can you please explain the knee lift mechanism and how to adjust it?
ReplyDeleteIt will not lift the presser foot. It sits securely in the socket, the mechanism itself works, the presser foot lifter works. The knee lift just doesn't meet any resistance..?
Place your sewing machine "on its back" and you will clearly see one screw that tightens the corresponding axle, pull the axle up and you will see the groove where the tensioning screw fits.
DeleteIt may happen that the tip of the screw is broken, it needs to be replaced if tightening is not possible.
I think it is indeed the screw tip broken off. I added pics and info to the f***a page.
DeleteAnd you didn't remember to at least provide the link where you found the answer to the broken screw tip, who knows how long you've been looking for help? this is just another proof that all that I do really does not make sense, I don't blame you, I blame myself. Best regards.
