1. Let’s Learn
the parts of
the Sewing Machine

2. These are our Sewing Machines

3. 1. Reverse Lever

4. The reverse lever allows you to stitch in reverse
The reverse lever allows you to stitch in reverse. We use reverse to make our stitches secure at the beginning and end of seams.

5. 2. Pattern Selector

6. The pattern selector lets you determine what kind of stitch you will be making, such as straight stitches or an embroidery stitch or zig-zag.

7. 3. Stitch Length

8. Stitch length determines the length of the stitch.
The range is from 0 to 4; the longest is 4
0 the shortest stitch.

9. 4. Bobbin Winder

10. The bobbin winder winds the thread from the spool to the bobbin, mechanically.

11. 5. Spool Pin

12. Spool pin holds the spool of thread.

13. 6. Thread Tension

14. Thread tension determines the tightness or looseness of the stitch.
*Students are reminded not to move this dial; each machine is set for the number on the tension dial that it needs.

15. 7. Pressure Dial

16. The pressure dial determines how much pressure the presserfoot will have on the fabric.
More pressure may be needed for light weight fabrics, and less pressure for heavy, or thick fabrics.

17. 8. Face Plate

18. The face plate is a cover that covers all the inner working parts of the sewing machine.

19. 9. Check Spring Holder

20. The check spring holder is actually hidden in our machines
The check spring holder is actually hidden in our machines. It works with the thread tension to slow down the amount of the thread going to the needle.

21. 10. Sewing Light

22. The sewing light helps you to thread the needle and to see your stitching; both day and night.

23. 11. Feed Dogs

24. Feed dogs are a “teeth-like”part that works with the presserfoot to pull your fabric through the machine.

25. 12. Throat Plate

26. The throat plate has stitching guide lines on it and has a hole for the needle to pass through to the bobbin casing

27. 13. Slide Plate

28. The slide plate is a clear plastic cover that covers the bobbin case to keep dust and dirt out of the moving parts area of the bobbin case.

29. 14. Presserfoot

30. The presserfoot holds the fabric against the feed dogs; so the feed dogs can pull your fabric through the machine.

31. 15. Needle Clamp

32. The needle clamp is a black clamp that tightens to hold the needle in place.

33. 16. Presserfoot Lifter

34. The presserfoot lifter gently lifts the presserfoot up and lowers it against the feed dogs.
Note: the presserfoot must be lowered before you begin to sew; or fabric will not move through the machine!

35. 17. Take-Up-Lever

36. The take-up-lever pulls the thread back after each stitch, so that the stitches will lay evenly into the fabric.

37. 18. Handwheel

38. The handwheel raises and lowers the needle
The handwheel raises and lowers the needle. You must always pull the handwheel towards yourself to prevent tangling of the threads.

39. 19. Clutch Knob

40. The clutch knob is located inside of the handwheel
The clutch knob is located inside of the handwheel. It is a safety feature of the sewing machine that when pulled out, prevents the needle from jabbing up and down when winding a bobbin.

41. 20. Power Switch

42. The power switch turns on the power on the sewing machine and also turns off the power, electrically.

43. 21. Power Socket

44. The power socket connects the power source to the sewing machine.

45. 22. Foot Pedal

46. The foot pedal operates the speed of the sewing machine, electrically.

47. 23. Thread Cutters

48. The thread cutters cut the threads at the end of a row of stitching to disconnect your fabric from the sewing machine.
