How to use and change the presser foot on the VALBERG VB-MAC sewing machine?
Frequently Asked Questions - 28/11/2025
Response Notice-Facile

The presser foot lifter is located in area C of your VALBERG VB-MAC machine. Before threading the machine or removing fabric, you must always lift the presser foot lifter to release the tension. Once the fabric is positioned under the presser foot, lower the lifter to hold the fabric in place while sewing.

Usage during sewing: After lowering the lifter, the presser foot holds the fabric against the feed dogs, allowing for a steady advancement of the fabric. Do not try to pull or push the fabric while sewing, as this could cause the needle to deviate and break. Simply let the machine feed the fabric naturally.

Removing the presser foot: To change the presser foot, start by fully lifting the presser foot lifter. Then, press the release lever located at the back of the presser foot holder to free the current foot. Once released, you can remove the presser foot.

Installing a new presser foot: Lift the presser foot lifter. Carefully align the new presser foot under the holder by positioning the foot correctly. Then lower the presser foot lifter until the cutout of the holder is directly above the fixing pin. The presser foot will automatically snap into the locked position.

Tension adjustment: The quality of your stitches also depends on the adjustment of the thread tension dial, numbered from 1 to 9. Positions 3, 4, and 5 (marked with a small square) constitute the optimal adjustment range for most stitches. Too high a tension will cause tight stitches and fabric puckering, while too low a tension will produce loose stitches. Always test the tension on a piece of identical fabric before starting your project.

Needle, fabric and thread guide

Different types of needles can be used with your machine, and these depend on the type of fabric you are sewing. Be sure to use the correct needle type and size to obtain the best results for your sewing projects.

- The most common needle types are regular-point and ball-point needles. The most commonly used sizes are: 11/80, 14/90 and 16/100. The smaller the number, the smaller the needle. The larger the number, the bigger the needle. Use smaller size needles for lighter weight fabrics and larger size needles for heavier fabrics. The table below provides some suggestions - with best results in mind - for matching the thread and needle type with various fabrics.

  • Regular-point needles are designed for use with woven fabrics, such as cotton, linen, silk, denim or twill.
  • The ball-point needles are designed for use with stretch knit fabrics, such as Spandex, mesh T-shirt fabrics or knits.

Threading the machine

The bobbin is located at the bottom of your machine and provides the lower thread for your stitches.

This sewing machine uses metal bobbins. The bobbin case is magnetised. Use the metal bobbin to obtain the correct tension for the bobbin thread. Always use 15K-type metal bobbins.

VALBERG VB-MAC - Threading the machine - 1

VALBERG VB-MAC - Threading the machine - 2

VALBERG VB-MAC - Threading the machine - 3

Important: Only use metal bobbins in this sewing machine. The bobbin thread is magnetically tautened. Therefore, a metal bobbin is required. Should transparent or plastic bobbins be used - even if they seem to fit into the machine - the machine will not be able to operate properly and unsatisfactory stitches will be obtained. Using metal bobbins will result in correct stitches.

Winding the bobbin

  1. Make sure the on/off switch is set to "OFF".
  2. Insert the spool base, spool of thread and spool cap onto the spool pin.
  3. The thread should face the back of the spool. Make sure that when the thread is pulled from the left, the spool of thread turns anticlockwise as shown.

• If the spool of thread is small enough, the spool pin can be lowered to a horizontal position.

VALBERG VB-MAC - Threading the upper thread - 7

Note: If the spool of thread is frayed at one end, position that end to the right to prevent the thread from getting caught whilst sewing.

- If the spool of thread is large and cannot fit over the spool pin in the horizontal position, lift the spool pin up into the vertical position. When using the vertical position, slightly loosen the spool cover or remove it completely from the spool pin, so that it won't prevent the spool from rotating whilst sewing.

Pulling the bobbin thread (lower thread)

After threading the upper thread and inserting the bobbin, the bobbin thread must be pulled out before the sewing process can begin.

  1. Make sure that the on/off switch is set to "OFF" and the machine is unplugged from the mains socket.
  2. Raise the presser foot lifter (1).
  3. To open the bobbin cover, push the bobbin cover release button to the right (2).
  4. Insert the threaded bobbin into the bobbin case, leaving the tail of the thread on the left. Make sure that the bobbin turns anticlockwise (3) when pulling the thread from the left.
  5. Hold the upper thread with your left hand and turn the handwheel towards you (anticlockwise) with your right hand to lower the needle (4) (5). Keep turning it until the needle rises to the highest position.
  6. Pull the upper thread upwards to pull the bobbin thread through the throat plate (6).
  7. Pull both threads through the throat plate and position them under the presser foot (towards the rear of the machine), leaving a thread tail of approx. 15 cm for both threads (7).
  8. Close the bobbin cover (8).

Thread tension

After having selected the correct needle and thread combination for the fabric being used, you may need to adjust the sewing machine's tension in order to ensure the correct stitch balance. A stitch is well balanced when the upper and lower threads appear the same on the fabric. Your machine is equipped with an adjustable thread tension dial. It allows tension to be exerted on the upper and lower threads as they pass through the machine to form a stitch.

Too much tension will produce a tight stitch which will cause the fabric to pucker.

Too little tension will produce a loose stitch.

When a uniform tension is exerted on the two threads, a regular stitch, i.e. a well-balanced one, is obtained.

The machine's thread tension dial is numbered 1 through 9, and settings 3, 4 and 5 are marked with a small square around the number to indicate the adjustment range at which most of your stitches will be made.

How does the tension work?

To help you understand the role tension plays on fabrics and threads, try this simple test.

Take 2 pieces of a medium-weight woven fabric - in a solid, light colour - that measure approx. 15 cm long.

Place a size 14 needle in the machine.

Thread the top of the machine with an all-purpose thread (darker colour) and put the same type of thread (lighter colour) in the bobbin.

Set the machine to stitch No. 3; one of the straight stitch options.

Sew the two pieces of fabric together, starting with an upper thread tension set to 1. Whilst sewing, slowly turn the tension dial from 1 to 9.

Sew another row by returning the handwheel to 1. You should see a balanced stitch on each row halfway between the start and end.

The different-coloured threads will allow you to see the effect that tension has on the upper and lower threads.

Well-balanced stitches

Tension test

To check that the upper thread has been properly threaded through the tension discs, perform this simple test:

  1. With the presser foot raised and the thread removed from the needle, pull the thread towards the back of the machine. You should only detect slight resistance and little or no needle deflection.
  2. Now lower the presser foot and pull the thread back towards the back of the machine. This time you should detect considerable resistance and much more needle deflection. If you do not detect any resistance, it means that you have not threaded the machine correctly and will need to rethread it.

*N.B.: This stitch can be created with the all-purpose foot; however, you will get a better result with the aforementioned specific foot (not supplied).

Straight stitch

The straight stitch is the stitch most frequently used for all types of sewing.

  1. To start sewing, first raise the presser foot lifter.
  2. Pull the upper thread and bobbin thread under the presser foot towards the back of the machine, leaving approx. a 15 cm tail of excess thread at the end.
  3. Place the fabric under the presser foot and then lower the presser foot lifter.
  4. Rotate the handwheel towards you (anticlockwise) until the needle penetrates the fabric.
  5. Start the machine by pressing the foot control. Guide the fabric with your hands. When you reach the edge of the fabric, stop the sewing machine.

VALBERG VB-MAC - Straight stitch - 1

WARNING!

Do not pull or push the fabric while sewing, as this may cause the needle to deflect and break.

  1. Turn the handwheel towards you (anticlockwise) until the needle is in the highest position, and then raise the presser foot lifter.
  2. Pull the fabric backwards and cut the excess thread with the thread cutter located on the side of the machine.

Reverse stitch

Reverse stitches are usually performed at the start and end of a seam. The goal is to block the threads at both ends of the seam so that it doesn't come undone.

B

Product usage

  • Set the stitch selection dial to a straight stitch (stitches No. 1-4), depending on the fabric being sewn.
  • Position the fabric under the presser foot, just level with the inside of the fabric's top raw edges.
  • Lower the presser foot and sew approximately 3 stitches.
  • Stop sewing, then hold down the reverse lever, located at the front of the machine. Keep it pressed while you reverse stitch 3 stitches.

VALBERG VB-MAC - Product usage - 1

Note: The reverse stitch length is pre-set, regardless of the selected stitch.

  • Release the reverse lever and sew forwards again, until you reach the opposite end of the fabric.
  • Hold the reverse lever down to sew approx. 3 reverse stitches again.
  • Release the lever to sew forwards again until you reach the end of the fabric.
  • Raise the presser foot lifter, then remove the fabric from the machine.

Zigzag stitch

The zigzag stitch can be used for finishing seams, appliqués or decorative stitching.

Finishing seams

The edges of the seams support the garment and should have a durable finish, especially if the fabric is prone to fraying.

Seams can be finished in two different ways: Trimmed after sewing the edge of the seam or overlocked. Try these techniques on a scrap piece of fabric first to determine which method is right for your project.

1. Overlocked seam finish

  • Set the machine to stitch No. 5 or 6 and attach the satin stitch foot (not supplied).
  • Then sew with the right side of the stitch at the edge of the seam. Evenly trim the seam edges.

VALBERG VB-MAC - Overlocked seam finish - 1

natural_image Line drawing of a sewing machine needle and foot (no text or symbols)

2. Decorative stitching

You can add a personal touch or spruce up your projects with decorative threads. Mix different types and colours of thread to create trim-like finishes on clothing, home décor items, crafts projects and more.

- Set the machine to stitch No. 7 or No. 8, depending on the style you are looking for.

B Product usage

  • Attach the satin stitch foot (not supplied).
  • If you are using thicker thread (like topstitching thread), be sure to change the needle to a larger size needle as well.

Appliqués

Appliqués are made by sewing pieces of certain-shaped fabric onto a base fabric to form a design or pattern. This technique offers unlimited creative possibilities.

1. Preparing appliqués

  • Apply iron-on tape with a paper backing to the back of the appliqué fabric, according to the manufacturer's recommendations.
  • Outline the shape of the appliqué, then cut this shape out of the fabric that was fused to the iron-on tape.
  • Remove the paper from the back of the tape. Position the appliqué on the base fabric, then fuse them into place.

2. Sewing appliqués

  • Set the machine to stitch No. 5: the satin zigzag stitch.
  • To sew the appliqué, sew it in such a way that the right side of the stitch falls from the outer edge of the appliqué, thus enclosing the fabric's raw edge. The left side of the stitch will enter the appliqué fabric.

Blind hem

The blind hem stitch is mainly used to create seemingly invisible hems on various types of projects, such as curtains, trousers, skirts, etc. There are two different blind hem stitch types to choose from on the machine: standard blind hem stitch (for hems on woven fabrics) and stretch blind hem stitch (for hems on stretch fabrics).

  1. Set the machine to stitch No. 9 for the standard blind hem stitch or to stitch No. 11 for the stretch blind hem stitch.
  2. Attach the blind hem foot (not supplied).
  3. Insert the appropriate needle for the fabric being hemmed ( “Needle, fabric and thread guide”).
  4. Thread the top of the machine and the bobbin with a thread colour that closely matches or blends with the colour of the item being hemmed.
  5. Fold and pin the fabric, as shown (1).
  6. Place the fabric under the blind hem presser foot (not supplied) with the fold of the fabric positioned in such a way that the needle only pierces the fold when the needle passes to the left. Make sure to remove the pins as you sew (2).
  7. When you have finished, fold the hem and press (3).

Multiple zigzag stitch

The multiple zigzag stitch is an ultra-versatile stitch. Use it for mending, inserting elastic or simply as a decorative embellishment.

Repairing a tear

  • Set the machine to stitch No.12 and attach the satin stitch foot (not supplied).
    • Cut any loose threads from the torn area.
  • To reinforce the torn area, place interfacing or a small scrap of fabric (a similar fabric and colour) underneath the tear.
    • Work from the right side to bring the edges of the tear together, and then sew them.
  • Use a hand sewing needle to pull the threads on the wrong side, then tie them off and cut them.
    • Cut off the excess underlay.

Inserting elastic

It is easy to insert a piece of elastic using the multiple zigzag stitch. As these stitches are very elastic, they are not prone to break when the elastic is stretched.

  • Set the machine to stitch No.12 and attach the satin stitch foot (not supplied).
  • If you are repairing a garment with a broken elastic, first remove the old elastic from the garment, then press down.
  • Divide the elastic and the area of the garment in which the elastic will be sewn into four parts. Place a pin at these four parts on the elastic and the garment.
    • Gently pull the elastic to evenly cover the fabric as you sew.

Manually sewing a buttonhole

  1. Attach the buttonhole foot.
  2. Place the fabric under the buttonhole foot and lower the foot onto the fabric at the point you would like to sew the buttonhole.
  3. Select stitch No. 13. Step on the foot control to sew 5-6 stitches at a slow speed, then release the foot control to stop (Fig. a).

The stitches are too loose or irregular.The stitch tension is unbalanced.Thread the upper thread and the bobbin thread again.
The needle is breaking.The needle is bent or warped.Replace it with a new needle.

Why is the thread making loops or folds under my fabric?

When the thread loops under your fabric, it is usually because it has not been threaded properly or there is an incorrect upper thread tension. In this case, follow these steps:

  1. With the presser foot lifter raised and the thread tension dial set to 4, re-thread the upper thread according to the threading diagrams indicated on your machine: Place the spool of thread on the spool pin and secure it with the thread spool cap. Whilst holding the spool of thread in place with your right hand, use your left hand to hold the thread and pass it through the thread guide, then follow the thread path, bringing the thread down through the tension channel, around the bottom of the machine and up the other side. Continue to thread the machine, but do not thread the thread through the needle.
  2. Before threading the thread through the needle, perform this simple test to make sure that the upper thread has been threaded correctly. While the presser foot is raised, pull the thread. It should be easy to pull. Then lower the presser foot. The thread should now resist when you pull it. There should be a significant increase in thread tension. If there is no more tension, the upper thread is threaded incorrectly. Try again ( “Threading the upper thread”).

Why is my machine skipping stitches?

Stitches may be skipped if the needles are dull or damaged, or if they have been incorrectly inserted in the machine.

- First, check whether the needle is dull or damaged, and replace it if necessary. Furthermore, make sure that you are using the correct needle size for the type of fabric being sewn ( "Needle, fabric and thread guide").

C

Cleaning and maintenance

- Then check that the needle is correctly inserted. The needle should be pushed as high as possible. It's easy to insert the needle halfway, tighten it and think that it's been properly installed. In addition, the flat side of the needle should be positioned backwards. If the needle is not inserted correctly, it will not be able to pull the bobbin thread, thus resulting in stitches being skipped.

Storage

• Always unplug the unit before storing it.
- Store the unit in a fresh, dry and dust-free place, out of the reach of children and pets.
- Please retain the packaging and use it to store your unit when it is not in use for an extended period of time.
