1-4. Change of needle
Needle is consumable. Use of bent needle or tip-damaged needle will cause thread breakage and skip stitch. Change the
needle when such troubles are distinguishing.
It is also necessary to change needle according to conditions such as thread to use, material, sewing method etc.

4. Thread
[Difference between sewing thread and embroidery thread]
Sewing thread (three-piece twist)
Its purpose is to sew fabric together and needs enough strength.
Embroidery thread (two-piece twist)
It is frequently used for decoration. It needs softness to emphasize
brilliance even if it overlaps.
3-piece
twist
2-piece
twist
4-1. Upper thread
Use left-twisted (Z-twisted) upper thread that fits to rotating direction of rotary hook (counterclockwise).
When catching thread in both hands and
turning thread to the direction indicated
by arrow, it is “left-twisted” if twisting of
thread returns. When thread twisting
becomes stronger, it is “right-twisted”.
4-2. Under thread
Cotton thread or polyester spun thread is popular (differs depending
An example of sample
on application). If you do not use the same thread as upper thread,
select thin thread count as much as possible (the back of fabric will
be finished softly).

MANUAL
5. Fabric stretching
Fix the fabric in the state of full stretch so that no lines remain on the fabric.
Clip
For multi head machine
When you attach frame holder or square frame, detach the border
frame sash (1).

The number of clips and their length
differ depending on frame size. Perform
equal arrangement by using all clips.

!
When you step on the table to perform working, perform the
working near the spot where the table support is set as close
as possible (only the model in which table supports are
packed together).

If thread does not pass to each section correctly, it is not

will occur).

MANUAL
7. Tension adjustment of thread
To make finishing of embroidery beautiful or to perform efficient works by reducing thread breakage, it is important to get
adequate tension of upper/under thread. Please perform adequate tension adjustment that is suitable to fabric or type of
thread to use, conditions etc.
7-1. Under thread tension
(a) When not using a measuring gauge
When you shake the bobbin case (3) up and down lightly in the state of under thread (1 in
the figure) not hooked to the thread guide coil (2), standard tension (20 to 35 g) makes the
bobbin case (3) descend slowly.
[When adjusting]
Loosening the adjusting screw (4) will make tension looser. Tightening it will make tension
tighter.

Use a small flat head screw

(b) When using a measuring gauge
Introduced hereunder are gauges to measure tension of upper/under thread. Please make good use of them (sold
separately).

(Upper/under thread tension measuring gauge)
BTG
(Under thread tension measuring gauge)

MANUAL
7-2. Upper thread tension
Adjust tension with thread apart from the thread presser 2 (illustration A below).
In the state of upper thread entangled
a. Remove entangling of thread at the first tension (1). It is all
right that only light tension is applied here.
b. Perform adjustment at the second tension (3) while pulling out
thread so that tension becomes 100 to 130 g.

8. Timing between needle and rotary hook
The timing (timing between needle and rotary hook) when the needle (1) meets the hook point (2) of rotary hook is very
important.
When the needle (1) moves up, the loop (4) generated under the fabric (3) affects finishing of sewing. Loop shape is
changed by “Fast”/“Late” timing between needle and rotary hook.
The description below only shows the relation between a needle and a rotary hook. This does not mean
recommendation of adjustment of timing between needle and rotary hook.

Large looping is not apt to
generate skip stitches.
Moving up quantity: large
9. Presser foot
When height of the presser foot (2) against the fabric (1) is improper, a gap will occur between the fabric (1) and the
needle plate (3). That will cause thread breakage, skip stitch, or bad thread tension. It is necessary to adjust height of
presser foot according to fabric thickness.

Good example
Presser foot should press the
fabric at needle sticking.

MANUAL
[How to adjust]
a. Turn OFF the power. After setting needle position to the first needle, rotate the main shaft counterclockwise (correct
rotation) by using the T-wrench (1). Set main shaft angle to 178° while checking descending of the needle bar.
b. Loosen the screw (2) to detach the cover (3) (figure b below).
c. Loosen the screw (4), and tighten the screw (4) with the presser foot (5) touching fabric (urethane (6) in this example)
lightly.
Adjust the second needle and after by the same manner (figure c below).
d. After adjusting of one head, check if height of presser foot is almost the same at any needle bar visually (broken line part in
the figure d below).

10. Thread breakage detector
The rotary slit (1) detects flow of upper thread/under thread.
When thread breakage occurs, the machine will stop at once.
It is possible to change sensitivity of thread
breakage detection on the operation panel.
For details, read “USER’S MANUAL”.

11. Middle thread guide with thread take-up spring
The thread take-up spring (2) keeps balance of upper thread/
under thread constantly at high-speed rotation, which makes
finishing of sewing stable.
Set it to the “basic position” usually. When
you move the lever (3) (two or three steps),
finishing of sewing will change (perform
adjustment according to need).

12. Upper thread lock (Not applied to some models)
Upper thread will be locked (fixed)/released according to
operational condition of the machine. Changing this timing will
improve finishing of sewing.
It is possible to change upper thread lock timing on the
operation panel. For details, please read “USER’S
MANUAL”.
