How to Adjust Bobbin Tension on Janome Sewing Machine

The bobbin is a crucial component in the sewing process. The bobbin tension should be adjusted to ensure that the fabric doesn’t loosen as it sews. This blog post will explore how to adjust bobbin tension on a Janome Sewing Machine.

If the thread is not feeding properly, or if it breaks easily while stitching, then the bobbin tension may be too tight.

If there are loops of thread under the fabric and/or stitches that look loose and sloppy, then the bobbin tension may be too loose.

This article will show you how to adjust your Janome sewing machine’s bobbin tension so that you can get back to creating beautiful pieces of work.

Full Guide On Adjusting Bobbin Tension on Janome Sewing Machine

You don’t have to take your machine in for service when something like this happens. Instead, just follow our simple guide and do it yourself. It only takes a few minutes and we promise you won’t regret learning this skill.

The Wheel

The horizontal adjustment wheel is located on the left side of the sewing machine body or under the handwheel at the back or behind the machine.

The wheel should be turned counterclockwise to raise bobbin tension, turning it clockwise will reduce bobbin tension. This is adjustable to the thickness of the fabric being sewn.

Stitch Length

The stitch length may also be adjusted by positioning the stitch length selector lever under the handwheel in either direction. The left position gives a smaller stitch and the right position gives a longer stitch.

Sometimes there may be numbers from one to five on top of the stitch length knob, these numbers represent the length of stitch between 1mm to 5mm.

The Knob

The regulating knob is generally located at the back or bottom right side of the machine which has screwed with a different thread-making holes on it.

Turn this adjusting screws regulates needle position by moving up and down, which also moves the feed dogs (the gears that move the fabric).

It can regulate the position of the needle to make straight stitching lines.

The Gap

The gap between two consecutive stitches is called stitch width, change it according to the fabric and design you are working on. Here is how the gap can be adjusted:

  1. Take out a bobbin case (if there is any). Pull hook race towards you and hold it with your fingers to prevent it from falling down.
  2. Turn the handwheel towards you until the presser foot is up. This will keep the needle at its highest position. Rotate to find a hole that has no thread behind it, usually, there are 5 holes of different sizes on some machines. The slant of this hole shows which stitch width has been selected.
  3. Loosen the screw located at the side of the presser bar and move it to that hole. Make sure you have picked the right stitch width before you tighten this screw. The default setting is usually 2mm, if it does not work for your fabric then try other numbers until the needle moves up and down freely in both forward and reverse stitching.
  4. Turn the handwheel towards you until the presser foot is down. Place fabric under the presser foot with the right side facing up, start sewing once you are ready.

The Pressure foot

Adjusting the presser foot pressure is also important, if not adjusted properly it will be difficult to go over thick seams.

To adjust this you have to turn the screw located on the right side of the presser bar clockwise for less pressure and anti-clockwise for more pressure. The default setting is usually 2.5mm or 3mm.

The presser foot pressure can make a difference when sewing thin and thick fabrics:

  • – Sewing thin fabric such as silk or chiffon, use minimum pressure.
  • – Sewing medium-weight cotton or synthetic fabrics, use normal setting.
  • – Sewing heavy fabric such as denim, use maximum pressure to avoid loose stitches.

Decrease the Stitch Length

To decrease the stitch length, turn the handwheel towards you while keeping your left index finger on the presser foot lifter up button until the presser foot is all way up. Take out a bobbin case (if there is any).

Turn needle position screw clockwise to move back the needle away from the bottom of cloth into a sewing machine, or counterclockwise to move the needle towards the bottom of the cloth. This will reduce the stitch length.

Increase Stitch Length

To increase the stitch length turn handwheel away from you and at the same time keep your left index finger on the presser foot lifter up button until the presser foot is all way down.

Turn needle position screw anti-clockwise to move the needle closer to the bottom of the cloth, or clockwise to move the needle away from the bottom of the cloth. This will increase the stitch length.

  • – Sewing thin fabrics such as chiffon or silk, use 1mm or 2mm for straight stitching.
  • – Sewing medium weight fabric such as cotton, use 4mm for straight stitching.
  • – For heavy fabric use 6mm or 7mm for straight stitching.

Adjust Stitch Width

You can also adjust the stitch width by turning the handwheel towards you while keeping your left index finger on presser foot lifter up button until presser foot is all way up, then take out bobbin case (if there is any).

Turn needle position screw clockwise to move back the needle away from the bottom of cloth into the sewing machine, or counterclockwise to move the needle towards the bottom of the cloth. This will reduce the stitch width.

Increase stitch width

To increase stitch width turn the handwheel away from you and at the same time keep left index finger on the presser foot lifter up button until the presser foot is all way down.

Turn needle position screw clockwise to move the needle closer to the bottom of the cloth, or counterclockwise to move the needle away from the bottom of the cloth. This will increase stitch width.

Final Word

It’s completely up to you when it comes down to adjusting the bobbin tension or not, but before doing so make sure everything else has been checked: threading process, stitches, and needle plate/feed dog issues.
