If the temperature is excessively low, the
machine can fail to operate normally.
WARNING
For the combination of the material and the thread and needle, in particular, refer to the explanation
table in “Replacement of the needle”.
If the needle or thread does not match the material used such as in the case that an extra heavy-
weight material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break result-
ing in an unexpected personal injury.
Other precautions
Do not put the sewing machine under the
direct sunlight or in a humid place.

Trial sewing, Thread tension
Sewing test
After threading make a trail run. Always use a double layer of
fabric to properly check the stitch formation and thread ten-
sion.
Switch the machine on (“I”).
Set all tensions to 4.
Stitch length, differential, cutting width (see adjustment &
settings).
Lower the upper knife.
Lower the presser foot.
Raise the front of the presser foot slightly with your thumb
and position the fabric under the foot just up to the knife.
Sew.
At the end of the seam continue sewing a 8cm (3”) long
thread chain (A). Cut threads.
When using thread such as cordonet or similar, pull out the
thread chain (B) carefully by hand as it might catch in the
stitch plate.
Check your trial run
1. Upper looper thread (blue).
2. Lower looper thread (red).
3. Right- hand needle thread (green).
4. Left- hand needle thread (yellow).
Perfect stitch formation is when both looper threads meet at
the fabric edge. The needle threads form straight stitches for
a stretchy and durable seam.
18
Trial sewing, Thread tension
Thread tension
Thread tension should be adjusted to suit the various types of work.
The ideal thread tension for most fabrics and threads is between 3 and 5.
However this can vary quite considerably when special threads such
as filament, woolly nylon, buttonhole twist (cordonet), pearl yarn or
decorative threads are used. Infinitely variable adjustments can be
made from 1-9. Move the lever upwards for more tension, move the le-
ver downwards for less tension.

Adjusting the thread tension
Lower or raise the tension levers by only half or one number, then test
sew again and check the result.
The loops are formed on the underside:
Tighten the upper looper thread tension, (blue) or loosen the lower
looper thread tension, red (D).
The loops are formed on the upper- side:
Tighten the lower looper thread tension, (red) or loosen the upper
looper thread tension, blue (E).
The right- hand needle thread forms loops on the underside:
Tighten the right- hand needle thread tension, green (F).
The left- hand needle forms loops on the underside:
Tighten the left- hand needle thread tension, yellow (G).
The edge of the fabric curls up, tension for both looper threads is too
tight:
Loosen upper and lower looper thread tension, blue and red (H).
The fabric puckers during sewing:
Loosen the right- or left-hand needle thread tension, green or yellow
(I).
19
Adjustments and settings
Stitch length
It can be adjusted while sewing. The stitch length is innitely variable
from 1-4mm. Most overlock work is done with a basic setting of 2.5mm.
MO-114D
MO-104D
Stitch length
Switch the machine off (Power switch to “0”).
Open the cloth plate, loosen the knob and adjust to the desired length.
Tighten the knob and close the cloth plate.
The stitch length is innitely variable from 1 - 4 mm.
Most overlock work is done with a basic setting of 2 - 3 mm.
Cutting width
• Switch the machine off (Power switch to “0”).
Open the cloth plate. Raise presser foot.
Push upper knife to the right and turn cutting width dial in the direc-
tion desired.
Close cloth plate cover and lower presser foot.
Cutting width:
1 = 3 - 5 mm seam width
2 = 4 - 6 mm seam width
3 = 5 - 7 mm seam width
The position of the lower knife determines the width of the seam.
Reduce cutting width (knife moves to the left) if the edges of the fabrics
curl up (A).
Increase the cutting width (knife moves to the right) if the loops are too
loose (B).

Adjustments and settings
Differential feed
There are two feed dogs, one front (C) and one rear (D). The two feed
dogs travel independently and the distance each feed dog travels
during one complete movement can be adjusted. The differential feed
prevents uting or waving in knitted or stretch fabrics and or closely
woven fabric (E).
Perfectly at seams in knits or stretch fabrics
The distance travelled by the front feed dog should be greater than that
of the rear feed dog. The front feed dog therefore, feeds an amount of
fabric which the rear feed dog can take up behind the needle without
stretching the fabric.
Pucker-free seams in nylon or closely woven fabrics
The distance travelled by the rear feed dog should be greater than
that of the front feed dog. The front feed dog therefore, holds the fabric
back so that the rear feed dog can take it up behind the needle without
any puckering. (F).

Gathering
Using the differential feed a single layer of fabric can be gathered be-
fore sewing it to a garment.
For example, sleeve heads and lower edges, yokes, lace edging or
frills.
Adjustment:
Stitch - 4 thread overlock
Differential feed – 2
Stitch length - 3-4
Cutting width - 2-3
Increase the needle thread tension (6-8) for a tighter gather.
Note:
When sewing without differential feed, turn the adjustment knob to “N”.
22
Adjustments and settings
MO-114D Upper looper converter (MO-114D)
Use the upper looper converter to sew stitches with one looper thread,
such as 2-thread roll hem, 2-thread atlock and 2-thread overlock.
Turn the handwheel to lower the needles.
Switch the machine off “O”.
Open the looper cover.
Attach the converter (accessory bag) to the upper looper arm (A). In-
sert the wire hook into the upper looper eye (B) from back to front.
The upper looper has now been converted, i.e. it no longer carries
thread but it diverts the lower looper thread so that loops are formed
round the edge of the fabric.
Roll hemming
Turn the handwheel towards you until the needles are fully raised.
For roll hemming, pull the selection lever to the front marking on the
stitch plate, furthest from the presser foot (C).
For overlocking push the selection lever forwards to the rear marking
on the stitch plate, nearest the presser foot (D).
The roll hemmer is fully integrated in the machine.
The edge of the fabric will be automatically rolled over, producing a
very narrow, ne seam or hem. Roll hemming is ideal for nishing edg-
es on all ne fabrics, such as evening clothes, lingerie, scarves, frills
and also for curtains and napkins.
23
Adjustments and settings
Presser foot pressure
The presser foot pressure is factory adjusted to a medium setting.
Should you wish to adjust it, simply turn the knob in the direction de-
sired:
Position of knob for normal pressure (A)
More pressure: for thick or stiff fabrics such as denim, tweed, rm linen
(B)
Less pressure: for lightweight or sheer fabrics and knits (C).
Settings and practical sewing
Thread breakage during sewing
Sew off immediately at an angle and remove the work. Re-thread. If the
