THREADING THE MACHINE
For threading the machine please check below drawing (thread the machine in order from 1-18).
THREAD TENSION ADJUSTMENT
Tension post No.1 is used to adjust the thread tension to sew on the
button and a relatively low tension will be enough.
Tension post No.2 is used to adjust the thread tension applied to the
root of the button sewing stitches.
This tension must be determined according to the type of thread, fabric
and thickness of the button and must be higher than tension set on
post No.1 .
Turn the tension nuts clockwise to increase or counterclockwise to
reduce the thread tension.
ADJUSTMENT OF THE THREAD PULL-OFF LEVER
To adjust the thread pull-off lever (1), insert a screwdriver through an
opening in the machine arm side cover (left), loosen screw (2) and
adjust the position of nipper bar block (rear) (3) to the left or the
right.
If the end of thread is drawn from arrow hole A in the button after
sewing, change the position of nipper bar block (rear) (3) to the left.
Move the lever to the right when the thread end comes out from
arrow hole B.

1. Depress the pedal fully forward, turn the needle driving pulley in the normal sewing direction to bring down the needle bar
to the lowest point and loosen screw (1) .
(Adjusting the needle bar height)
2. Adjust the height of the needle bar using top two lines engraved on the needle bar for the TQxl needle and using the bot-
tom two lines for the TQx7 needle.
Align the upper line A with the bottom end face of needle bar bushing (lower) (3) and tighten screw (1) in the way that needle
clamp screw (4) rests in the slot of the needle bar bushing (lower) (3).
(Looper position)
3. Loosen screws (5) and turn by hand the needle driving pulley until lower line B of two lines aligns with the bottom end face
of needle bar bushing (lower) (3).
4. By keeping the machine in this state, align looper blade (6) with the center of the needle and tighten screws (5).
5. Loosen screws (7) and provide a 0.01 to 0.1 mm clearance between the looper and the needle. Tighten screws (7).
ADJUSTMENT OF THE NIPPER
Provide 0.8 to 1.2 mm clearance between nipper (1) and nipper block (2) to prevent the nipper from nipping the thread
while stitching. Loosen screw (3) and move nipper bar block (4) to the left or the right.

TIMING OF THREAD TENSION RELEASE
Tum the needle driving pulley as you draw the thread in the direction of the arrow as illustrated and you will find a point at
which the tension disc on the tension post No. 2 release the thread. At this moment, the standard distance from the top end of
the needle bar to the top end of the needle bar bushing (upper) is 44 to 47 mm. Perform the following adjustments especially
when the undermentioned troubles occur frequently.
Loosen nut (1) , insert the blade of a screwdriver to the top slot of the tension post No. 2 and turn it in the direction of the
arrow to lower the needle bar, (to reduce the said distance), and vice versa.
Phenomenon Height of needle bar
1. When the stch made
on the wrong side of the
workpiece is too loose;
Make the needle bar
slightl higher.
2. When the thread is
broken at the me of
stop-moon;
Make the needle bar
slightl higher.
3. When the thread is
broken frequentl ;
Make the needle bar
slightl lower.
SETTING FOR 2- OR 4-HOLES BUTTONS
Measure the distance between two holes in a button and set equally
crosswise and lengthwise feed regulators for 4-hole buttons.
Lengthwise feed
Push down lengthwise feed adjusting lever (1) and set it to 0 for 2-
holes buttons or the corresponding amount for 4-holes buttons
Crosswise feed
Loosen nut (2) and set pointer (3) to a corresponding amount indicated by the crosswise feed regulation plate. Tighten firmly nut
(2).
Before operang the machine, ensure that the needle enters the center of each hole in the buon.
AUTOMATIC THREAD TRIMMER
Position of the moving knife
When the machine stops in the state of ―stop-motion" and
its button clamp assembly rests in the highest position, there
must be a standard clearance of 12.5 mm between thread trim-
ming connecting link (front) (1) and the end face of the slit in
throat plate (2). This clearance is determined by gauge (3) which
is stored in the accessory box; tilt the head backwards, remove
the bed oil shield, loosen two nuts (4) and adjust the clearance
by moving connecting screw (5) in the axial direction. When you
tighten two nuts (4), ensure that joint(6) stays in the horizontal
position.
