Items requiring special attention i

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.

11. This is a Class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

. MAINTENANCE

1.

Adjusting the needle-to-hook relation

WARNING :


q

A

B

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.

C

0.05 mm e q

0 to 0.2 mm w

(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

q

WARNING :


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.

r e q

(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 :


q

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.

4. Adjustment of the bobbin presser unit

WARNING :


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 .

q e w

− 50 −

5. Thread tension

q w w q e r

(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 takeup 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.

6. Cleaning the filter

Table

WARNING :


Clean filter w of the fan located on the bottom surface of the machine table (bed base) once every week.

1) Pull the screen kit q in the direction of the arrow to remove it.

2) Wash the filter w under running water.

3) Reinstall the filter w and the screen kit q .

Hole under table for fan w q

7. Replacing the fuse

WARNING :

1. To avoid electrical shock hazards, turn OFF the power and open the control box cover after about five minutes have passed.

2. Open the control box cover after turning OFF the power without fail. Then, replace with a new fuse with the specified capacity.

q w e

The machine uses the following three fuses : q For pulse motor power supply protection
