Frequently Asked Questions - MD18610 Stirling

How do I thread the machine correctly?

Thread in this order: lower looper (purple), upper looper (blue), right needle (orange), left needle (green). Follow the color-coded guides inside the front cover. Use the tweezers for help. Always turn the hand wheel towards you.

How do I adjust the thread tension?

Use the four tension dials (1-4). Lower numbers reduce tension, higher numbers increase tension. For balanced stitches, both needle threads should meet in the middle, and looper threads should be evenly distributed. Refer to the table in the manual for specific fabric settings.

How to replace a needle?

Switch off the machine and unplug. Turn hand wheel to raise needles to highest position. Loosen the clamp screw with the small screwdriver. Remove the old needle. Insert a new needle (type 130/705H) with flat side facing back, push fully in, and tighten. The left needle sits slightly higher than the right.

Why is my machine skipping stitches?

Common causes: bent/blunt needle, incorrect needle insertion, improper threading, or wrong needle type. Check needle condition, reinsert correctly, rethread the machine, and ensure you're using type 130/705H needles.

How do I clean and lubricate the machine?

Unplug the machine. Open front cover and free arm. Use the brush to remove lint and dust. Apply a few drops of high-quality sewing machine oil to the marked points (see manual diagram). Close covers and sew on test fabric to remove excess oil.

How to convert to two-thread operation?

Switch off and unplug. Remove the right needle and its thread, and the upper looper thread. Insert the two-thread converter into the upper looper: hook the rear into the slot, then the front into the eye. Use only the left needle.

How do I set the differential feed?

Turn the differential feed dial (0.7 to 2.0). Use positive feed (1-2) for knit fabrics to prevent wavy seams, neutral (1) for normal stitching, and negative feed (0.7-1) for lightweight fabrics to prevent puckering. Can be adjusted while sewing.

How to replace the upper knife?

Unplug the machine. Turn hand wheel to bring upper knife to lowest position. Open front cover and free arm. Loosen the screw on the knife mounting, remove old knife. Insert new knife so its blade extends 0.5-1 mm beyond the lower knife's cutting edge. Tighten screw.

What should I do if the thread breaks or jams?

First, check threading: ensure the thread passes through all guides and tension discs correctly. Also verify the tension is not too high. If jammed, cut threads and carefully rethread following the order. Use the tweezers to clear any tangled threads.

How do I store the machine properly?

After use, switch off and unplug. Clean the exterior with a soft dry cloth. Cover with the supplied dust cover to protect from dust. Store in a dry location to prevent rust on metal parts.

Setting the stitch length

Turn the stitch length dial (7) until the desired length is shown. The higher the number, the longer the stitch.

The stitch length can be set from 1 to 5 mm.

Almost all overlocking tasks are carried out with a stitch length of 2.5 to 3.5 mm.

Setting the stitch length

Stitches Stitch length
Normal seams	2.0–4.5 mm(Default setting:3.0 mm)
Narrow bindings 1.0–2.0 mm
Rolled hems 1.0–2.0 mm
Picot edge 3.0–4.0 mm

Setting the cutting width

The appropriate cutting width varies from fabric to fabric. Examine the seams in each case and adjust the cutting width as follows:

- Turn the cutting width adjustment knob (14) to the desired setting.

The correct cutting width

Reducing the cutting width

Choose a narrower cutting width if the fabric edges curl when sewing.

- To do this, turn the cutting width adjustment knob clockwise.

Increasing the cutting width

Select an increased cutting width if the thread is sewn over the edge of the fabric.

- To do this, turn the cutting width adjustment knob anticlockwise.

Replacing needles

This machine is supplied with type 130/705H needles (for domestic machines)

NOTICE! Risk of damage!

Bent or blunt needles can cause damage to the machine and sewing fabric.

▶ Switch off the machine.
▶ Replace the defective needle.

• Turn the hand wheel (9) towards you until the needles (22) are in the highest position.
• Loosen the clamp screw from the needle using the supplied small screwdriver from the accessory compartment and remove the needle: upper screw for the left needle and lower screw for the right needle.
• Push the new needles into the needle holder with the flat side facing backwards. When doing so, ensure that they are pushed in as far as possible.
• Tighten the needle clamp screw again.

If the needles have been inserted correctly, the left needle is positioned slightly higher than the right. If the needles have not been inserted correctly, stitches will occasionally be missed.

Replacing the knife

Switch off the machine and the power point and pull out the plug before replacing the knife.

The lower knife is made of special material and does not need to be replaced.

This is how to replace the upper knife when it becomes blunt:

1. Turn the hand wheel (9) towards you until the upper knife (32) is at its lowest position.
2. Open the front cover (12) and the free arm (13).
3. On the upper side of the knife, push the mechanism down completely to reach a stable position for the distance adjustment.
4. Use the screwdriver from the accessory box to loosen the screw on the knife mounting (30) and remove the upper knife.

5. Insert a new upper knife and tighten the screw of the mounting slightly.

6. Now position the upper knife in such a way that its blade extends beyond the cover of the cutting edge of the lower knife by 0.5–1.0 mm (see illustration). Close the free arm before checking the gap, and open it again to read the value correctly.

7. Now tighten the screw of the mounting of the upper knife securely and close the free arm and the front cover.

Disengaging the upper knife

If you would like to sew without simultaneously cutting the edges, you can disengage the upper knife.

NOTICE!

Risk of damage!

If the fabric edge is too wide, this can damage the upper looper and the needles.

▶ Make sure that the edge of the fabric is not wider than the seam width you have set.

1. Switch off the machine and the power point and pull out the plug.
2. Open the front cover (12) and the free arm (13).
3. Use one hand to hold the free arm in place, and turn the dial for the knife mounting (30) to the left.
4. Then turn the knife mounting forwards until the knife has been rotated by 180^irc (see illustration).

Converting to two-thread operation

You can also use your machine solely as a two-thread machine. To do so, use the two-thread looper and the left needle only.

1. Switch off the machine and the power point and pull out the plug.
2. Open the front cover (12) and the free arm (13).
3. Remove the right needle and the threads for that needle and for the upper looper (see also 'Replacing needles' on page 34).
4. Take the two-thread converter out of the accessory compartment (27) of the front cover.
5. Insert the two-thread converter into the upper looper (25). (see Figure 1)
6. To do so, insert the hook on the rear end of the converter into the slot of the upper looper. (see Figure Point A).
7. Now insert the hook on the front end of the converter into the eye of the upper looper. (see Figure Point B).
8. The converter should now be positioned directly against the upper looper. (see Figure 2)

Narrow and wide overlocking with three threads

This machine can be converted from four to three threads when overlocking.

- Remove either the left or right needle and the corresponding thread (see also 'Replacing needles' on page 34).

The machine is now ready to overlock with three threads.

When using only the right needle the stitch width is 4 mm.

When using only the left needle the stitch width is 6 mm.

Stitch finger

When sewing light fabric with three threads, loops may form on the seams. In that case, change over the stitch finger (35).

• Switch off the machine and the power point and pull out the plug.
• Open the front cover (12) and the free arm (13).
• Release the stitch finger A with the supplied screwdriver and pull it out.
• Take the second stitch finger B out of the accessory box in the front cover.
• Push the stitch finger all the way in.

Blind hem, narrow edges or picot edges

For thin fabrics such as crepe de chine, georgette or silk, rolled hems, narrow hems or picot edges are suitable for creating a clean seam.

Due to the fine nature of these hems, they are not suited to firm or heavy fabrics.

Proceed as follows to set the machine up:

• Raise the presser foot (23).
• Open the front cover (12) and the free arm (13).
• Remove the stitch finger (see 'Stitch finger' on page 41).
• Remove the left needle and the corresponding thread.
• Set up the machine in accordance with the table.

If required, set the stitch length and cutting width.

Edge Thread	tension Stitch length	Cutting width
Rolled hem	Needle: 4upper looper: 4lower looper 4	R 4–6
Narrow hem	Needle: 4upper looper: 4lower looper 0	2–2.5 4
Picot edge	Needle: 4upper looper: 4lower looper 4	P 4–6

Differential feed

The differential feed prevents wavy seams on knit fabrics and stops layers of fabric from slipping. It also prevents lightweight fabrics from puckering.

How it works

The machine has two sets of feed dogs, one front set (A) and one rear set (B). Both of these sets move independently. Due to the feed motion, both sets of feed dogs can move at different speeds.

The feed can be set from 0.7 (negative feed) to 2.0 (positive feed).

Positive differential feed

With positive differential feed, the front feed dogs (A) move further than the rear feed dogs (B). This 'accumulates' fabric under the presser foot, preventing the fabric from becoming wavy.

Technical line drawing of a mechanical assembly with no visible text or symbols

Negative differential feed

With negative differential feed, the front feed dogs (A) do not move as far as the rear feed dogs (B). This stretches fabric under the presser foot, counteracting undesirable puckering of the fabric.

Technical line drawing of a sewing machine tool (no text or symbols present)

Setting the differential feed

The differential feed is set by turning the differential feed control (8). The feed can also be set while sewing.

Use the following table to select a setting:

Application Feed type Setting
Non-wavy seams, gathering	positive differential feed	1–2
No differential feed	Neutral feed	1
pucker-free seams	negative differential feed	0.7–1

Setting the presser foot pressure

The factory-set presser foot pressure is correct for all common sewing tasks and does not need to be adjusted.

If the pressure of the presser foot needs adjusting despite this, you can regulate it using the dial on the rear of the front cover for regulating presser foot pressure.

- Turn the dial (20) to a higher number to increase the pressure or to a lower value to reduce the pressure.

Sewing with cord/ decorative yarn

Corded seams are used for strength when sewing knit fabric shoulder, sleeve and side seams.

Decorative use of knitting yarn in a contrasting colour can also add an attractive feature to the finished garment.

The machine is equipped with a sewing foot that enables the cord or decorative yarn to be fed to the right or the left of the safety stitch.

To do this, proceed as follows:

1. Place the filler cord, such as crochet yarn, gimp, wool, knitting wool or shirring elastic, behind the spool pins (6).
2. Pass the thread through the eye on the telescopic thread guide bar (5).
3. Pull the cord through the thread guides (18) and then through the thread guide for the left needle.
4. Pass the cord either through the front or rear slot on the presser foot (23) (depending on the sewing method) and lay it under and to the rear of the presser foot.
5. Insert the fabric as usual. Sew slowly and check whether the cord is being fed in properly. Then increase your sewing speed.
6. When sewing shoulders together or sewing on sleeves, pass the cord through the front slot on the presser foot.

When doing so, ensure that it remains between the right and left needle threads when passing through the front slot on the presser foot.

1. To close the side seams, pass the cord through the rear slot on the presser foot, ensuring that it is positioned to the right of the needle thread.

For decorative effects, use a contrasting colour of yarn, which you can thread either through the front or rear slot.

Storage

Store the sewing machine in a dry location to prevent rust from forming on the metal mechanical parts.

Always use the supplied cover to prevent dust from getting into the sewing machine.

Cleaning and lubrication

To ensure your machine works properly, you must clean the mechanism from time to time using the brush from the accessory box and oil the relevant points.

Use only high-quality sewing machine oil to oil this sewing machine. You can purchase this from specialist retailers.

Use a dry, soft cloth to clean the exterior housing. Do not use chemical solvents or cleaning products because these may damage the appliance's surface and/or labelling.

This machine requires only a little oil because the main components are made of a special material.

1. Disconnect the machine from the power supply before opening the machine.

2. Open the front cover (12) and the free arm (13). Remove the accumulated dust and lint using the lint brush (48) provided as an accessory.

3. Apply a couple of drops of oil to the marked points. Use only high-quality sewing machine oil.

4. Close the free arm and the front cover.
5. For test purposes, now sew with a piece of test fabric to check that the machine is working correctly. The excess oil is eliminated directly without damaging your actual sewing.
