Frequently Asked Questions - Harmony 8100 JANOME

How do I thread the Janome Harmony 8100?

Step 1: Raise the presser foot and turn the handwheel to raise the needle to its highest position. Step 2: Place a spool on the spool pin and guide the thread through the upper tension discs and down through the take-up lever. Step 3: Continue threading through the needle clamp from front to back. Step 4: Pull about 4 inches of thread under the presser foot.

How do I wind the bobbin?

Step 1: Place the empty bobbin on the bobbin winder shaft and engage it. Step 2: Guide the thread from the spool through the bobbin winder tension disc. Step 3: Wrap the thread around the bobbin a few times. Step 4: Push the bobbin winder to the right and press the foot controller. The bobbin will fill. Note: The needle does not move during winding.

How do I adjust the thread tension?

Turn the upper tension dial (located on the front of the machine) to adjust. Lower numbers (0-3) reduce tension, higher numbers (4-9) increase tension. For balanced stitches, the upper and lower threads should interlock in the middle of the fabric. Test on a scrap piece first.

How do I change the needle?

Step 1: Turn off the machine. Step 2: Loosen the needle clamp screw using the provided screwdriver. Step 3: Remove the old needle. Step 4: Insert the new needle with the flat side facing the back, pushing it up as far as it will go. Step 5: Tighten the screw securely.

How do I select a stitch?

The stitches are selected using the pattern selector dial (right side of machine). Turn the knob to align the desired stitch symbol with the indicator. For example, a setting of 'A' may correspond to a straight stitch. Refer to the stitch chart on the machine for details.

How do I clean and maintain the machine?

1. Unplug the machine. 2. Remove the needle plate and clean the bobbin area with a small brush (included). 3. Wipe the exterior with a soft cloth. 4. Oil the hook race (if recommended) using the oil bottle provided. 5. Cover when not in use. Consult manual for specific intervals.

What should I do if the machine jams?

1. Turn off the machine and unplug it. 2. Remove the fabric by cutting threads carefully or reversing the handwheel. 3. Open the bobbin case and remove any tangled thread. 4. Check needle for bending or dullness; replace if needed. 5. Retread machine and try again.

How do I make a buttonhole?

1. Install the buttonhole foot. 2. Set the stitch pattern to buttonhole mode (usually a special symbol). 3. Insert the button into the slider on the foot. 4. Lower the foot and sew the four steps: forward, reverse, left side, right side. The machine will stop automatically when complete.

Why is the needle hitting the presser foot?

This is often due to incorrect needle insertion or a bent needle. 1. Check that the needle is properly inserted (flat side back) and fully pushed up. 2. Ensure the needle size is appropriate for the fabric and presser foot. 3. Replace the needle if bent. Also check that the presser foot is securely attached.

How do I replace the presser foot?

1. Turn off the machine. 2. Raise the presser foot lever. 3. Push the release button at the back of the foot holder to remove the foot. 4. Align the new foot with the holder and snap it into place. Ensure it is secure before sewing.

Pressure Dial

The pressure dial should be set at “3” for regular sewing. Reduce the pressure to “2” for appliqué, cut work, drawn work, basting and embroidery.

Set the pressure to “1” when sewing chiffon, lace, organdy and other fine fabrics. Velours and knits with a lot of stretch may also require a “1” setting.

Align the number on the dial with the setting mark.

① Setting mark

Up/Down Needle, Auto-Lock and Reverse Buttons

• Up/Down Needle Button

When this button is pressed, the needle bar goes down and stops in the lowest position. When pressed again, the needle bar goes up and stops in the highest position.

② Up/down needle button

• Auto-Lock Button

When stitches 1 , 2 or 3 are selected, the machine will immediately sew locking stitches and automatically stop when the auto-lock button is pressed. When sewing all other stitches, the machine will sew locking stitches at the end of the current pattern and automatically stop.

③ Auto-lock button

- Reverse Button

When stitches 1, 2, 3 and selected, the machine will sew in reverse while the reverse button is pressed. If you press the reverse button when sewing all other stitches, the machine will immediately sew locking stitches and automatically stop.

④ Reverse button

Selecting Needle and Thread

For general sewing use needle size 11 or 14. A fine thread and needle should be used for sewing lightweight fabrics, so the fabric will not be marred. Heavy fabrics require a needle large enough to pierce the fabric without fraying the needle thread.

In the needle case you will find Two size 14s, two size 11s and one blue tipped needle. Use a blue tipped needle to eliminate skipped stitches when sewing knits and synthetic fabrics.

There are also specialty needles available from your sewing machine dealer. A denim needle with a sharp tip is used to effectively pierce dense fabrics such as denim and canvas. For topstitching, a special topstitching needle with a larger eye accommodates heavier weight thread. Leather needles punch small holes in leather and suede allowing the thread to follow through the hole.

Check your needles frequently for rough or blunt tips. Snags and runs in knits, fine silks and silk-like fabrics are permanent and are often caused by damaged needles.

Always purchase a good quality thread. It should be strong, smooth and consistent in thickness.

Adjust the Top Thread Tension

- Choose the Correct Tension

For Straight Stitch:

The ideal straight stitch will have threads locked between the two layers of fabric, as shown left (magnified to show detail).

If you look at the top and bottom of the seam, you will notice that there are no gaps; that each stitch is smooth and even.

When adjusting top thread tension, the higher the number, the tighter the top thread.

Results depend on;

* stiffness and thickness of the fabric
* number of fabric layers
* type of stitch

① Needle thread (Top thread)
② Bobbin thread (Bottom thread)
③ Right side of fabric
④ Wrong side of fabric
⑤ To loosen
⑥ To tighten

• Tension is too tight

The bobbin thread shows through on the right side of the fabric and it will feel bumpy.

Turn the dial to the left to loosen the top thread tension.

① Right side of fabric
② Wrong side of fabric
③ To loosen

• Tension is too loose

Overcasting

• Zigzag Stitch

This stitch can be used on most woven fabrics. It's the fastest way to finish an edge, leaving it neat and flat.

A dense zigzag can also be used for appliqué.

① C: Overedge foot

Set the stitch width from 0.5 cm (3/16") to 0.7cm (9/32") when the overedge foot C is used to prevent needle breakage or damaging the foot

• Multiple Zigzag

This stitch is used to finish the seam allowance on synthetics and other fabrics that tend to pucker. The stitch is excellent for darning and mending tears. Place your fabric to allow a 1.5 cm (5/8") seam. Trim the seam allowance after sewing.

Note:

Be careful not to cut the stitches.

SECTION IV PROFESSIONAL STYLE EMBROIDERY

Getting Ready to Sew Professional Style Embroidery

- Interfacing

Interfacing material for embroidery is available in adhesive type (iron-on) and non-adhesive type. Interfacing should be attached to the wrong side of fabric. (More than one layer may be required).

The non-adhesive type should be used with fabric which cannot be ironed or on sections which are difficult to iron. For both types, cut the interfacing larger than the embroidery frame and set it on the frame so that the entire piece is fastened in it.

* Note that the ironing temperature varies with the kind of adhesive interfacing.

Selection of interfacing

To obtain perfectly formed letters, it is important to use the correct interfacing:

* Adhesive type (iron-on) Use for stretch fabric (such as knit), thin fabric and shrinkable fabric.
