# Juki Sewing Machine

# Safety Considerations

- When not in use - turn off and unplug
- Don’t put your fingers too close to the needle when you’re feeding the fabric through
- Declutter the table of sharp objects like scissors etc.
- Thread the machine properly
- Tie long hair back
- Pay attention when sewing
- Keep control of the fabric

# Thread Types

- Monofilament - clear thread used for sewing elastic on to feather flags
- 60s bonded nylon white/black - a strong thread used for SEG systems, barrier jackets and tablecloths etc.

**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](https://manual.maticmedia.co.uk/uploads/images/gallery/2022-09/scaled-1680-/threading.png)](https://manual.maticmedia.co.uk/uploads/images/gallery/2022-09/threading.png)

**Follow the guide above using the colour coding: <span style="color: #e131e4;">Left Needle</span> <span style="color: #3598db;">Right Needle</span>**

**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

<p class="callout info">Used for barrier jackets, Heras fence banners and most other types of finishing.</p>

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 **<span style="color: #000000;">1</span>** and take the bobbin out of its housing.
3. Replace the empty bobbin and lower the latch.

# Sewing Kedar



# Troubleshooting



# Thread Keeps Snapping or Shredding

This is usually because the needle is blunt - Change the needle

# Material is all bumped up after sewing



# End of the material keep getting stuck in material guide



# I can't sew in a straight line

Use some scraps of material and practice, you'll soon get the hang of it.
