My singer 4423 has 3 needle positions.. Unfortunately the centre position has shifted to the left somehow and is now off centre to the foot. This is partly corrected by shifting the needle position guage but even on the furthest setting to the right its still off centre. Does anyone know how to correct this.. It was fine before but and has recently started this off centre position..

If your machine has that capability, the manual should have instructions on how to move the needle. If not, then your machine may need adjustment.

Hi there,

The needle threader hook is very tiny and easily bent or damaged.
The needle threader is designed not to turn, if the needle is not at its most upper position to protect the threader - Turn hand wheel until needle reaches its highest position.
Needle not alining with threader hook - Replace needle.
Threader hook bent - Replace with new needle threader hook.

Hope this helps.

Good luck & have a nice day!

Automatic needle threader will not work

Make sure needle position is placed in middle position "M" before making selection. http://www.singerco.com/uploads/download/a719909a6ca001462cb1c2536a04506fa9ff327c.pdf

You have to drop the lever above the needle until it clicks to lock it in place

According to this manual (pg 52):

http://www.searspartsdirect.com/partsdirect/user-manuals/3116-SINGER-SEWING%20MACHINE-manual

the zipper foot position is adjustable, not the needle position.

i looked up the manual and didn't see anything about needle position. Here's a copy so you can read at your leisure.

You need to have your singer re-timed. Take it in and pay the $$ to have it serviced.

Hi. Here's how to attached the zipper foot.

To Attach the Zipper Foot
1. Loosen the large screw at the left of the presser bar and remove presser foot (You do not need to remove the screw).
2. Hook the prongs of the Zipper Foot around the presser bar from the back, and tighten the presser-bar screw.
3. If the raised edge (zipper or cording) is to the right of the needle, adjust the Zipper Foot by loosening the thumb screw at the back of the foot and sliding foot to the left of the needle. If the raised edge is to the left, slide foot to right.
4. With presser foot down, check its position by lowering needle into side notch, making sure it just clears the foot.
5. Tighten thumb screw to lock foot into position.
When raised edge is placed to right -- adjust foot to left of needle.
When raised edge is placed to left -- adjust foot to right of needle.
