· The anatomy of a needle, so they insert it facing the correct direction—scarf to the right.
https://en.wikipedia.org/wiki/Sewing_machine_needle--The scarf of the needle is referred to in the directions for changing the needle in the operating instructions manual for the machine.
(Summer is working on preparing the manual for upload.)

+Please refer to the manual to learn the anatomy of the machine. You will need to know how to replace a broken or damaged needle. The needle must be seated with the scarf to the right.

−· Question proving they know the difference between S- and Z-twist in thread and how that relates to proper threading of the machine. Attach the diagram, or insert a link to the diagram. (Because if they use thread with the wrong twist for the needle, the machine will jam up.)

https://makernexuswiki.com/wiki/Consew_206RB-4_Walking_Foot_Industrial_Sewing_Machine This is the wiki for some folks who have a very similar machine. Most of their links look good, but should be viewed before being adopted--just to be sure they're relevant. The text is very good--terms and directions are clear and correct; I'd imitate that as much as possible.

−https://www.superiorthreads.com/education/thread-twist-explained--'S' and 'Z' twists are very clearly explained. On the Consew you must use 'left twisted thread for upper/needle thread, but you can use either right or left twisted thread for lower/bobbin thread.' According to the folks at Superior the terms left and right twist are not correct terminology. They have a video embedded in the article that explains everything. The Consew needs Z-twist for the needle; Z-twist is the same as left twist. It might be nice to have a loupe among our tools, so students can check this before they thread the machine.
