I'm trying to insert a zipper with my Husqvarna Viking Opal 650 and the instruction book shows to use the E foot but on my Graphic Display it doesn't show what # to use. Appreciate any assistance

SOURCE: Husqvarna Viking #1 use same foot pedal as the #1+ ???

Yes it will work, you can go ahead and purchase it.

SOURCE: I can't figure out how to shift the needle to the left

When topstitching using straight stitch the needle position can be adjusted in steps. The stitch width button(+), 0 is the center position, width 6 isleft needle position,width6 mirror image(diamond half clear and half black)is right needle position.
hope this helps, it is from the manual.

Hello,

i need a manual for my Husqvarna 215 sewing machine.
can you help me?

SOURCE: How to use a zipper foot please

1. Step 1 To prepare the fabric for a centered zipper application, use the standard presser foot to baste the opening of the fabric shut using 5/8 inch seam allowance. Press the seam allowance open. Place the zipper teeth side down on the seam allowance and pin the zipper to the seam allowance only.
   
2. Step 2 Release the standard presser foot from your machine. There may be a button or lever behind the foot that you need to press. Put the standard foot in its holder or someplace where it won’t get lost.
   
3. Step 3 Decide which side of the machine you want to attach the zipper foot to. Zipper feet are asymmetrical, with one side that’s wider than the other. You’ll want to put the narrow side toward the zipper teeth, and the wider side away from the zipper teeth.
   
4. Step 4 Attach the zipper foot to the sewing machine. You may need to line up the bar on the zipper foot with the presser foot holder, then lower the presser foot by lowering the lever. Raise the presser foot and make sure the zipper foot is securely attached.
   
5. Step 5 Place the prepared fabric with the pinned zipper in the sewing machine. Lower the needle into the zipper tape and the seam allowance only, then lower the zipper foot. Stitch the zipper tape to the seam allowance. To sew the other side of the zipper to the seam allowance, remove the zipper foot from the sewing machine and install it on the other side of the presser foot holder.
   
6. Step 6 Topstitch the outside of the fabric to each side of the zipper tape, making sure that the zipper foot is on the appropriate side of the machine for each side. Remove the basting with a seam ripper.
