*Verify that you are using the correct presser foot. When changing out the presser foot, manually check that the needle’s travel will clear the foot before using the foot pedal.
*Be very careful to keep loose clothing and hair away from the pulley. If it grabs a loose sleeve, it could break your hand; if it grabs your hair, it could remove a piece your scalp. No dangling necklaces or earrings either! (Don't make me explain this.)
*For the safety of the machine always remove the bobbin from the machine before using the winding mechanism. Also, do not turn the handwheel manually without being certain to hold the thread tails for bobbin and spool to make certain they do not become entangled in the bobbin case.
*When you finish using the sewing machine, disconnect the power cable from both the machine and the wall outlet/power strip. Coil the power cable neatly on the table.
==Description==
==Description==
These are the things to know in order to succeed on the Consew:
Become familiar with the contents of the manual located in the top drawer of the storage unit under the serger/sewing machine table. It's full of misspellings and grammatical errors for now, nevertheless, it's helpful. Where it ceases to be helpful is in the description of the clutch motor which our Consew no longer possesses; our Consew has a servo motor. To understand why you should be happy about this, please view the first 5'44" of this video:
{{#evu:https://www.youtube.com/watch?v=lavkvsU5ltk&ab_channel=AlexanderDyer}}
Please refer to the manual to learn the anatomy of the machine.
*Question regarding the thread controller spring, because they’ll need to make that adjustment themselves and should know what it is, where it is, and how to do that.
*Make sure the bobbin case is empty before trying to fill another bobbin. If there is a bobbin left in the bobbin case when winding a new bobbin a thread jam will occur in the bobbin case. Congratulations! You just broke it!

*Following the safety protocol.
*Threading the machine
*Filling the bobbin, because people are going to need thread to match their project.
*We need a demo project or projects to choose from. Leather or upholstery?
*They should have to prove they can remove and replace the needle. This is where they need to know what the scarf is and which direction it should face.
*Double checking the stitch speed and stitch length, and that they know how to change those settings.
*Adjusting thread controller spring is simple and should be known and demonstrated since its function is dependent on the materials being used.
*In the instruction for the demo students should be encouraged to do test samples before stitching on their actual project.
*I think for the most inexperienced it would be helpful to remind them ‘righty-tight/lefty-loosey re: the tension knob.
*Stitch length dial works differently than the instruction book says; there is no stopper.

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.youtube.com/watch?v=lavkvsU5ltk (Helps explain the difference between the machine as it was originally powered--by a clutch motor, and as it is powered now--with a servo motor. Should offer some reassurance to newbies that they will be able to operate the Consew safely. Also, helps explain why parts of our manual aren't relevant.)

'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.

You will need to know how to replace a broken or damaged needle. The needle must be seated with the scarf to the right. You can be certain the needle is fully seated when you cannot push it up any further in the needle bar. See this article regarding a needle's structure: https://en.wikipedia.org/wiki/Sewing_machine_needle
[[File:S-and-z-twist-figure.png|250px|thumb|right|The difference between S-twist and Z-twist thread.]]
On the Consew you must use z- or left twist thread for upper/needle thread, but you can use either s-/right or z-/left twisted thread for lower/bobbin thread. If you use the wrong thread in the needle it will unravel, and the machine will jam. To learn more about this, see [https://www.servicethread.com/blog/left-twist-vs.-right-twist-industrial-sewing-thread-differences-and-applications this explanation].

==Troubleshooting==
Every time you change the needle make sure it is still aligned over the needle hole by turning the flywheel one complete rotation toward you. If the needle does not pass cleanly through the needle hole, tell Justin. Do not sew!
If the machine is skipping stitches it needs a timing adjustment; don’t sew—tell Justin.
Irregular stitch length or overheating; don’t sew—tell Justin.

====General maintenance====
====General maintenance====
*Clean lint, thread, and debris from feed dogs, bobbin area, and under needle plate after each use.
*Oil moving parts according to the manual - use sewing machine oil only and avoid over-oiling.
*Check belt tension and condition - replace if frayed, cracked, or slipping.
*Inspect needle for bending, dullness, or burrs - replace regularly to maintain stitch quality.
*Keep tension discs clean and free of lint or residue.
*Verify presser foot pressure and feed timing periodically - adjust as needed for consistent fabric feeding.
*Tighten screws, nuts, and bolts to prevent vibration-related loosening.
