The reverse lever allows you to stitch in reverse. We use reverse to make our stitches secure at the beginning and end of seams.
The pattern selector lets you determine what kind ofstitch you will be making, such as straightstitches or an embroidery stitch or zig-zag.
Stitch length determines the length of the stitch The range on our machine is from 0 to 4. 0 the shortest stitch, 4 the longest.
The bobbin winder winds the thread from the spool to the bobbin, mechanically.
Feed dogs are a “teeth-like”part that works with the presserfoot to pull your fabric through the machine.
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.
The hand wheel raises and lowers the needle. You must always pull the hand wheel towards yourself to prevent tangling of the threads.
The clutch knob is located inside of the hand wheel. 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.
The power switch turns on the power on the sewing machine and also turns off the power, electrically.
The presser foot holds the fabric against the feed dogs; so the feed dogs can pull your fabric through the machine.
The presser foot lifter gently lifts the presser foot up and lowers it against the feed dogs. Note: the presser foot must be lowered before you begin to sew; or fabric will not move through the machine!
The foot pedal operates the speed of the sewing machine, electrically.
The take-up-lever pulls the thread back after each stitch, so that the stitches will lay evenly into the fabric.
The thread cutters cut the threads at the end of a row of stitching to disconnect your fabric from the sewing machine.
