When a hook has been replaced, be sure to check the
position of the hook needle guard.
As the standard position of the hook needle guard, hook
needle guard 󱀀must push the side face of needle 󰿿to
lean the needle by 0.05 to 0.2 mm away from its straight
position.
If the aforementioned standard state is not achieved,
insert a screwdriver (small) 󱀂into needle guard ad-
justment screw 󱀁and adjust the position of the needle
guard.
1) Place the machine in the hook timing adjustment
mode.
2) To bend the hook needle guard in direction a, turn
the needle guard adjusting screw in direction A.

1) Open the hook cover. (How to open : move the
hook cover to the right or left after lifting it right
above.)
2) Turn the handwheel in its normal rotational direc-
tion to bring bobbin case opening lever 󰿿to its
back end position.
3) Turn inner hook 󱀀in the direction of the arrow
until stopper 󱀁is pressed against the slits in throat
plate 󱀂.
4) Loosen bobbin case opening lever crank setscrew
󱀃. Adjust the clearance between the bobbin case
opening lever and protruding portion Aof the bob-
bin case to 0.2 to 0.3 mm.
5) Tighten setscrew 󱀃while pressing down bobbin
case opening lever crank 󱀄.
6) Move inner hook guide 󰿿up and down to make
sure that there is not play in the thrust direction.
WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the following
work after turning the power o󰀨 and ascertaining that the motor is at rest.
5. Adjusting the bobbin case opening lever
In case of 2-needle machine, perform the
same adjustment to the right and left hooks.
4. Adjusting the hook needle guard
3) To bend the hook needle guard in direction b, turn the needle guard adjusting screw in direction B.
4) At the nal step of procedure, appropriately ad-just the clearance provided between the needle and the hook.
WARNING :
To protect against possible personal injury due to abrupt start of the sewing machine, be sure to change
over the operation mode to the "hook timing adjustment mode".
The presser foot automatically goes up when changing over the operation mode to the "hook timing
adjustment mode". In addition, the presser foot also comes down when the "hook timing adjustment
mode" is nished and the power is turned OFF. Be sure carry out the operation while keeping your hands,
etc. away from the presser foot.
For the sewing machine which is provided with the stitch skipping detecting device, the light emitted by
the sensor LED may light into the eye to cause dazzling when adjusting the hook timing.
To avoid this, cover the LED before adjusting the hook timing.

Angle display
1) Place the machine in the hook timing adjust-
ment mode.
2） For the right hook, loosen the setscrew in the
side cover on the operator's side to remove the
side cover.
(For the left hook, remove the side cover on
the opposite side of the operator.)
3） Loosen opener camsetscrew 󱀃.
4) While checking the angle displayed on the
screen, turn the handwheel to bring the hook
to the angle shown in the table. In this state,
tighten setscrew 󱀃of opener cam at the posi-
tion where opener 󰿿starts to move from the
position farthest from the protruding portion 󱤪
of inner hook 󱀀.
At this time, tighten setscrew 󱀃of opener cam
in such a way that a clearance of 0.2 to 0.5 mm
is provided between the top surface of opener
cam 󱀄and the undersurface of opener arm 󱀁󱀁.
5） Install the side cover with the side cover set-
screw.
6） Press button to exit from the hook timing
adjustment mode.
Carry out angle correction before start-
ing adjustment of the opener timing to
make sure that 0° is displayed when the
needle bar is at its upper dead point.
In the case of the 2-needle sewing ma-
chine, opener arm clamping screw 󱀂 of
the left hook is located on the opposite
side of the operator.
WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the following
work after turning the power o󰀨 and ascertaining that the motor is at rest.

screen and select "9. Hook timing adjustment
mode".
2） Placing the dial gauge against the needle
clamp, turn the handwheel to bring the needle
bar to its upper dead point.
After you have adjusted the origins of the motors (main motor, feed motor, presser motor and alternating vertical
movement motor), correct the reference angle of the main motor.

6) Enter a correction value on the operation panel
so that the angle you have checked in Step 3
becomes "0" (zero) or "360".
For example, enter "-5" if the angle you have
checked in Step 3 is "5". Enter "8" if the angle
you have checked is "352".
7) Press to conrm the value you have
entered.
8) Enter the "Hook timing adjustment mode".
Check that the angle "0" (zero) is displayed

The needle thread tension can be corrected according to the bobbin thread remaining amount.
The needle thread tension can also be set on the operation panel. The needle thread tension data is stored in
memory.
1) Set "U201 Bobbin thread remaining amount for
starting correction" with numeric keypad 󰿿.
Using the aforementioned set value, determine
the remaining amount of bobbin thread indicat-
ed on the bobbin counter for starting the nee-
dle thread correction.
For the setting method of the bobbin thread
counter, refer to "6-3. Counter function p.75"
of the main body manual.
The set value can be reset to the initial value
of 0 by pressing 󱀀.
2) Set "U202 Final correction amount" with the
numeric keypad 󱀁.
Using the aforementioned set value, determine
the correction ratio of the needle thread ten-
sion.
The set value can be reset to the initial value
of 100 by pressing 󱀂.
3) When 󱀃is pressed, the entered val-
ue is conrmed and the screen is returned to

When you start to correct the needle tension in ac-
cordance with the remaining amount of the bobbin
thread, a line appears below the set value of the
thread tension setting button.

– 18 –
In the case the correction is made as shown in
the gure
The needle thread tension correction starts when
the bobbin-thread remaining amount shown on the
bobbin counter reaches "70 % (U201)", and the nal
correction amount "150 % (U202)" is reached when
the bobbin counter reaches "0" (zero).
For the section from 70 % to 0 %, the correction
along the inclination of the line chart is applied.
The bobbin counter starts counting down from
the target value "200". When it reaches "140", the
needle thread tension correction starts. When the
counter reaches "0" (zero), the needle thread ten-
sion is corrected by "150 %".
