I have an Elna 945 computerised overlocker am am experiencing a problem when overlocking......when I lift my foot off the pedal the machine just carries on working!! I have even uplugged the foot pedal from the machine and it still carries on sewing!! This happens after the overlocker has been working for a while. What could be causing this??

SOURCE: Elna 9000 sews automatically

Most likely this is a problem in the foot control and it will need to be replaced or repaired.

SOURCE: What make of walking foot

You need a low shank style walking foot. Even back in the 80's when your SU air electronic was new, the walking foot sold by Elna was an after market one, and not made by Tavaro. Same with the ruffler attachment, it was after market and actually fitted quite a few makes of machine.

I would just ask the dealer/shop if they will refund your money if you find it doesn't work just in case.

There is a low shank one on sewingpartsonline.com
http://www.sewingpartsonline.com/walking-foot-low-shank-p60444.aspx and they list the SU as compatible with it.

Take off the foot holder on your mache, and you need to fit the little open ended arm over the needle bar and the foot bracket onto the foot with your machine's regular thumb screw. The up and down movement of the needle bar operates the walking foot.
