Repairing a faulty Elna air electronic foot control:

I’ve set out the following faults that can be checked before buying a new foot control. The easiest way of finding these faults are to dip it in water,  close off the foot control head and apply pressure on the air control membrane to see where the air bubbles escape. This should give you a good indication where the foot control is leaking air.

Finding and repairing the leak

1. Foot control hose 988667-003: The Elna foot control Hose 988667-003 can get a hole or cut. You can always cut out the damaged part of the hose and providing it is still long enough use the narrow plastic ink tube of a empty ballpoint pen to join it.



2. Membrane 436410-10: It is not worth trying to repair the Membrane 436410-10



3. Elna hose head 436410-H: Elna Hose Head 436410-H can get little cracks and won’t seal anymore



4. Membrane holding plate: Membrane holding plate gets cracked from age or when the four holding screws are tightened to hard. You will get a leek between the membrane and the holding plate



5. Elna hose head 436410-H: You can easily repair your hose in the same manner as the Singer Foot control below

It can be easily repaired using the inner tube of a old ballpoint ink pen

Cut a piece of tube for connecting the hoses

Insert the plastic tube halfway into the hose

The spring scale N° 101’670 is calibrated at the factory and should not be modified.

Referring to the first picture in the picture gallery below on how to set the tension on the lower bobbin case:

Elna lotus hook drive gear | 408101

We have an Elna Lotus about 35 years old. It’s black Hook Drive Gear has broken and needs replacement. I can not take the old one out. Do I need any special tool to take the old one out? It appears that the old black hook drive has been replaced by white hook drive. Am I correct?
