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.

6. MAINTENANCE

1.Adjusting the needle-to-hook relation

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 off and ascertaining that the motor is at rest.

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.

0.05 mm

0 to 0.2 mm

(3) Adjusting the bobbin case positioning stopper

Adjust with setscrew e so that the contact of the top end of bobbin case positioning stopper q and the end of inner hook w is 0 to 0.2 mm.

2. Adjusting the needle thread trimmer

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 off and ascertaining that the motor is at rest.

(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.

(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).

3. Adjusting the presser bar pressure

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 off and ascertaining that the motor is at rest.

4. Adjustment of the bobbin presser unit

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 off and ascertaining that the motor is at rest.

To adjust the pressure applied by the presser bar to fabric, turn presser spring regulator q. When the

pressure is not enough to prevent fabric from puckering, turn regulator q clockwise.

8 to 15mm

Loosen nut w and adjust the position with stopper spring e so that the distance from the front end of machine bed to bobbin presser q is 8 to 15 mm when the sewing machine stops. Then tighten nut w.

− 50 −

Page 56

5. Thread tension

(1) Thread take-up spring (purl stitch)

1) The thread take-up amount of thread take-up spring

q is 8 to 10 mm, and the appropriate pressure at

the start is approximately 0.06 to 0.1N.

2) To change the stroke of the thread take-up spring,

loosen screw w, insert a thin screwdriver into the slot of thread tension post e, and turn it.

3) To change the pressure of the thread take-up

spring, insert a thin screwdriver into the slot of thread tension post e while screw w is tightened,

and turn it. Turning it clockwise will increase the

pressure of the thread take-up spring.

Turning it counterclockwise will decrease the

pressure.

(2) Adjusting the thread take-up amount of the

thread take-up lever

The thread take-up amount of the thread take-up lever

should be adjusted in accordance with the thickness

of the sewing products so as to obtain well-tightened

stitches. a. For heavy-weight materials, loosen setscrew w in

thread guide q, and move the thread guide to the

left. The thread take-up amount of the thread take-

up lever will be increased.

b. For light-weight materials, move thread guide q

to the right. The thread take-up amount of the

thread take-up lever will be reduced.
