FOR SAFE OPERATION
1. To prevent possible accidents due to electric shocks, neither open the cover of
motor electrical box nor touch the component(s) inside the electrical box.
2. Make sure of the needle entry after changing the pattern. Should the pattern protrude
from the work clamp check, needle interferes with the work clamp check resulting in
the danger of occurrence of needle breakage or the like. In addition, check that the
work clamp check which has been set corresponds to that which has been installed
on the sewing machine.
1. In case nothing is displayed in the operation panel even when the power switch is
turned ON, turn OFF the power switch and check the power voltage and phase.
2. To avoid personal injury, never put your fingers under the thread take-up lever, cloth
presser, cloth cutting knife, or needle when you turn the power switch ON or operate
the sewing machine.
3. To protect against possible accidents due to abrupt startup of the machine, turn
OFF the power switch before tilting the machine head or removing the motor cover.
4. To avoid personal injury, never bring your fingers, hair or clothing close to V belt,
cloth cutting knife or motor during operation, and never place anything on any of
these parts.
5. To avoid personal injury, never operate the machine with the motor cover, eye
protection cover, or any other safety devices removed.
6. To avoid personal injury, be careful never to allow your fingers to go inside the
machine when tilting or raising the machine head.
7. To prevent possible accidents due to electric shocks or damaged electrical
component(s), always turn OFF the power switch before connecting or disconnecting
the power plug.
8. During thunder and lightning storms, stop your work and disconnect the power
from the outlet to ensure safety and prevent possible accidents due to damaged
electrical component(s).
9. If the machine is suddenly moved from a cold place to a warm place, dew
condensation may result. If this occurs, be sure to confirm that there are no potentially
dangerous water drops in the machine before turning it on in order to prevent possible
accidents due to damaged electrical component(s).
10. In the event of a power failure, be sure to turn OFF the power to the machine to
protect against damaged electrical components.

Adjust the needle-to-hook relation when the needle
enters the center of the needle hole in the throat plate.
(1) Needle bar height
1) Bring down the needle bar to the lowest point.
2) Insert the part [1] A of timing gauge into the gap
between the bottom end of needle bar and throat
plate, where the bottom end of the needle bar
touches the top of the part[1] A of the timing gauge.
3) Loosen needle bar connection screw q, and adjust
the height of the needle bar.
(2) Set the needle to hook relation in the following
way :
1) Rotate the hand pulley in the correct direction until
the needle starts to go up from its lowest point.
2) Insert the part [2] B of the timing gauge into the
gap between the bottom end of the needle bar and
the throat plate, where the bottom end of the needle
bar touches the top of the part [2] B of the timing
gauge.
3) Loosen setscrew C of the hook sleeve, and align
blade point of the sewing hook with the center of
needle hole. Make adjustment so that a clearance
of approx. 0.05 mm is provided between the needle
and the blade point of the hook.

following work after turning the power off and ascertaining that the motor is at rest.
q
w
(1) Adjusting the thread grasping force of the
needle thread trimmer
If the needle thread trimmer fails to provide consistent
thread grasping force, the needle thread can slip off
at the beginning of sewing.
1) If the thread grasping force of the needle thread
trimmer has reduced, loosen setscrews q and
detach needle thread trimmer w.
2) Slightly bend the top end of thread presser spring
e so that it comes in contact with thread trimming
blade of upper knife r over the length with no
clearance and so that the needle thread trimmer
securely holds the thread regardless of the position
of the thread trimming blade at which the thread is
trimmed.
q
r
e
(2) Adjusting the height of the needle thread
trimmer
To adjust the height of the needle thread trimmer,
loosen setscrew q. Set the height of trimmer as low
as possible, provided that it does not touch work clamp
check, in order to minimize the length of remaining
thread on the needle after trimming.
Note that the work clamp check tilts when sewing a
multi-layered portion of the material, attach the needle
thread trimmer to slightly raise the installing position
of the trimmer.
When replacing the needle thread
trimmer, make sure that the trimmer
normally works under the needle thread
trimmer adjusting mode (memory switch
level 2 : K51).
