Here are some safety instructions for the {{PAGENAME}}. Remember... SAFETY FIRST!!!
 +
*'''Sharp Hazard''' – needles are very sharp and can pierce your skin. Turn off the sewing machine when inserting/removing needles to avoid bumping the foot pedal and moving the needle assembly. Never place your fingers directly underneath the needle.
 +
*'''Crush Hazard''' – be aware of all moving parts and keep your fingers away from any pinch points.
 +
*'''Entanglement''' – ensure that loose clothing, long hair, or any other dangling/loose items do not become entangled in the machine. Hair that extends below the collar should be tied up.
 +
*'''Eye Injury''' – needles can break if they hit a solid object while sewing. The broken tip can fly off and become lodged in your eye. Wear safety glasses when using the heavy duty sewing machine.
 +
*While it is improbable that you will use pins with this machine, do not sew over pins. This can break or bend the needle.
 +
*Ensure the needle you are using is undamaged.
 +
*Make sure the needle is installed correctly.
 +
*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.

Here are some safety instructions for the Heavy Duty Sewing Machine. Remember... SAFETY FIRST!!!

  • Sharp Hazard – needles are very sharp and can pierce your skin. Turn off the sewing machine when inserting/removing needles to avoid bumping the foot pedal and moving the needle assembly. Never place your fingers directly underneath the needle.
  • Crush Hazard – be aware of all moving parts and keep your fingers away from any pinch points.
  • Entanglement – ensure that loose clothing, long hair, or any other dangling/loose items do not become entangled in the machine. Hair that extends below the collar should be tied up.
  • Eye Injury – needles can break if they hit a solid object while sewing. The broken tip can fly off and become lodged in your eye. Wear safety glasses when using the heavy duty sewing machine.
  • While it is improbable that you will use pins with this machine, do not sew over pins. This can break or bend the needle.
  • Ensure the needle you are using is undamaged.
  • Make sure the needle is installed correctly.
  • 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.

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:

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!

RE: Changing the needle

It’s easy to do, but will you want the students to seek the help of the ace or a tech?

I verified a screwdriver key, such as the ones purchased for the Janomes,  will work for loosening the screw holding the needle in place. One has been added to the notions drawer in the worktable for the Consew.

RE: Demo and instructions for it, (These things need to included.)

·       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.

·       Part of reformatting the uploaded/downloaded instruction manual should be marking which adjustments listed in the contents should only be performed by the tech. (Or maybe those parts of the manual shouldn’t be on the WIKI at all, in order to avoid confusion.)

General remarks:

Do we need a toolkit especially for the Consew? Something like the sewing kits that we have for the Janomes. One that has upholstery sewing needles, etc. . . . We don’t really have any instructions for how to sew with an industrial, not even in the manual. Things like checking for your thread tails to make sure they're behind the work and won't become entangled in the stitching. Or where your hands should be while stitching.

Documentation

Terminology

The scarf of the needle is referenced in the "changing the needle" instructions in the user manual.
  • Bobbin: The metal drum that holds the lower thread.
  • Foot:

User Manual

Training

Operation

Make sure the dots on the handwheel and frame are aligned before removing or inserting a bobbin.


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

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 this explanation.

Demonstration

RE: Safety protocol

·       Eye protection

·       Removing and replacing the needle. Needs to be part of the training/demo.

Certification

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.
