Tension post No.1 ❶ is used to adjust the thread
tension to sew on the button and a relatively low
tension will be enough.
Tension post No.2 ❷ is used to adjust the thread
tension applied to the root of the button sewing
stitches. This tension must be higher than that of the
tension post No.1 and be adjusted according to the
sewing conditions.
Turn the respective nuts clockwise to increase
the thread tension.
2. Adjustment of thread hauling amount
❶
Adjustment of thread hauling amount is performed
by loosening setscrew ❶ and move the position of
thread guide ❷ .
When the end of thread is drawn from arrow hole A
in the button after sewing, move the thread guide in
the direction of A in the figure, and the end of thread
is drawn from arrow hole B in the button, move it
in the direction of B in the figure so that the end of
thread is not drawn.

3. Timing of thread tension release
Turn the hand pulley as you draw the thread in the
direction of the arrow as illustrated and you will find a
point at which the tension disk on tension post No.2
releases the thread. At this moment, the standard
distance from the top end of the needle bar bushing
(upper) to the top end of the needle bar is 54 to 56

4. Adjustment of the thread tension guide on the face plate
When the machine fails to form a seam at the start
of sewing and starts to form it after it has run a while,
adjust the thread tension guide on the face plate if
the aforementioned trouble cannot be corrected by
adjusting the thread pull-off lever.
❶
1) If the machine fails to form a seam at the
start of sewing, reduce the thread tension by
turning thumb nut ❶ (double nut).
5. Adjustment of needle-to-looper relation
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
Slightly loosen knob ❶ located on the right side of
the sewing machine, turn cover ❷ in the direction of
the arrow, and you will find hand pulley ❸ inside it.
The rotating direction of this pulley is in the direction
of the arrow.
❷
❶
1) Turn hand pulley ❸ to bring down needle bar
❺ to the lowest point of its stroke and loosen
setscrew ❹ .
❸
2) Adjust the height of the needle bar using top two lines engraved on the needle bar for the TQx1
needle and using bottom two lines for the TQx7 needle. Align the upper engraved line A with
the bottom end face of needle bar bushing (lower) ❻ and tighten setscrew ❹ .
3) Loosen setscrew ❼ and turn the pulley ❸ in the normal sewing directionuntil lower engraved
line B aligns with the bottom end face of needle bar bushing (lower) ❻ .
4) By keeping the machine in this state, align looper blade ❽ with the center of the needle and
tighten setscrew ❼ .
5) Loosen setscrew ❾ and provide a 0.05 to 0.1 mm clearance between the needle and looper.
6) When the adjustment is completed, return cover ❷ to the home place and tighten knob ❶ .
