Juki Sewing Machine

Safety Considerations

Thread Types

The sewing machine performs best using 60s bonded nylon for the machine head and monofilament for the bobbins
as this thread lasts much longer than 60s thread.

Threading the sewing machine head

Threading.png

Follow the guide above using the colour coding:  Left Needle  Right Needle

Note; If using a single needle, you must use the right needle and remove the left one. Also, remove the left bobbin.

Single Needle Operation

When using a single needle make sure it's the right side needle.

Remove the left needle and bobbin and un-thread the left side of the machine before use.

Twin Needle Operation

Used for barrier jackets, Heras fence banners and most other types of finishing.

The twin needle creates two parallel lines of straight stitches meaning the stitches are less likely to break giving longer life to the product.

Tacking (Front and Back)

Reverse feed stitching or back tacking is when the sewing machine makes a few reverse stitches at the beginning and end of the main stitch. This reinforces the stitching, reducing the likelihood of it coming undone from the ends.

You can achieve this in 2 ways;

  1. By pressing the sewing machine pedal back with your heel (it back tacks automatically)
  2. By using the reverse feed lever 1. The stitch goes in reverse when pressed down and forward again when released.

  1. Turn the power off before replacing the bobbin.
  2. Lift the latch 1 and take the bobbin out of its housing.
  3. Replace the empty bobbin and lower the latch.
