Singer 201 How to look after and maintain and use the Singer 201 correctly. 1.Introduction.

Due to my work/family history in first light engineering and the then into mainly Orthopaedic operating theatres as a nurse. I have a wealth of knowledge on engineering matters and find the 201 a "walk in the park" in comparison of what I had to deal with on a daily basis at work. Unfortunately I am now seeing a whole raft of videos and blog sites that tell you to do this and that and to use this product etc etc and strip the machine down no matter what state its in. Which I know is to the detriment of the machine. This I feel is incorrect and wish to redress the balance on how to look after them correctly from an engineering point of view. All types of machines will be dealt with 201 1 to 4. Photo stills and write up will be on FaceBook site Singer 201K/221K Sewing Machine.
