How to replace needles
Your problem has been posted against the Elna 2007 mechanical sewing machine - not sure if this is your machine but it shouldn't make much difference. All domestic sewing machines have very similar needle placement.
The needle bar is the piece that goes up and down and holds the needle. There is usually a housing at the bottom with a thumb screw that is used to secure the needle. To change, turn your flywheel towards you until the needle is at its highest point. Turn off the motor or unplug machine for safety. Hold the needle with one hand and undo the thumb screw with the other. Insert a new needle into the housing FLAT SHANK TO THE BACK, all the way up into the housing, then tighten the thumb screw.
Standard domestic sewing machine needles are coded 130/705H and almost all makes and models will use this type of needle. Industrial machines are different and some overlockers/sergers will use a slightly longer needle called ELX.
The important thing is to change the needle regularly, about 4-6 sewing hours is maximum before the point starts to go blunt. If you can hear a squeaking or popping sound as you stitch, this is most likely a blunt needle. Also use the right sized and type of needle for the work you are doing. So for knits and jerseys, use a ball point needle to avoid skipped stitches. For lycra use a stretch needle coated with blue, helps with this synthetic fibre.
For wovens, use a sharp or universal point but pick the right size for the weight of fabric. Sheers, organza and fine silks, use a 60. Lightweight cottons, use 70. Medium weight fabrics use a 80 etc, right up to 110 size for coated upholstery fabrics. There are special needles for denim too as this is a very densly woven fabric so again, a blue coating helps to get the needle through the fibres.
I trust this helps you to resolve your problem.
