CAUTIONS ON USE

Lubrication

• When a new sewing machine is first operated, or when a sewing machine is operated which is out of use for a long period of time, it will be necessary to oil through the oil holes after removing the rubber plugs shown below.
• See dripping of oil through the oil sight hole to check the oiling condition during operation.

For oil, Use white spindle oil

Winding of bobbin thread

Note: When the bobbin thread is wound, keep the presser foot lifted.
Adjustment:

• Tension of wound thread
  Slack winding is recommended for polyester thread and nylon thread.

• Conically wound thread
  Move the thread guide toward the smaller diameter of the wound thread layer.
  Length of wound thread
  Loosen the thread length adjusting the screw to increase the length of the thread and tighten the screw to decrease the length of the thread.

Attaching the needle

• Note: Before installing the needles, be sure to turn off the power.

Selection of thread

It is recommended to use the “S” twist thread in the left needle (viewed from the front), and the “Z’ twist thread in the right needle. When the use of needle threads discriminates is impossible, use “Z” twist thread in both needles. For the bobbin thread, the “S” twist thread, as well as the “Z” twist thread, can be used.

Threading of needle threads

1. Pass each needle thread through thread guide“A”. Note: When thin slippery thread (polyester thread or filament thread, for example) is used pass the thread through thread guide “B” as the wall.
2. With the take-up lever located at the uppermost position, pass each needle thread in the order shown in the following figure.
   Note: Pressing the upper thread loosening button shown in the figure below opens the saucer of the upper thread tension adjuster, and the upper thread can easily be pulled out

Setting of bobbin

1. Pulling out 5. cm thread tail from the bobbin.
2. Hold the bobbin so that the bobbin thread is wound in the right direction and put it into the hook.

Threading of bobbin threads

1. ut the hook into the bobbin case and press down the latch ①.
2. While holding the two needle threads with the left hand, rotate the hand-wheel one turn with the right hand. By pulling up the needle threads, as shown in the figure, the bobbin threads will be lifted. Each combination of bobbin thread and needle thread should be aligned and led backward.

Thread tension

1. Adjusting the bobbin thread tension Turn the tension screw, clockwise to increase the bobbin thread tension, or counterclockwise to decrease it.
2. Adjusting the needle thread tension

• Needle thread tension should be adjusted in reference to bobbin thread tension.
• Turn tension nut clockwise to increase the needle thread tension, or counter clocking to decrease it.
• Needle thread tension can be also adjusted for special fabric and thread by changing intensity and movable range of slack thread adjusting spring.

Thread take-upspring

1. To change the stroke of thread take-up spring

• Loosen screw“4”in the stopper, and move stopper“3”to the right or left.
• Move the stopper to the right to increase the stroke of the thread take-up spring, or to the left to decrease it.

To change the tension of the thread take-up spring

Loosen nut“2”and screw“5”.Turn spring shaft“1”counter clockwise to increase the tension of the spring, or clockwise to decrease it. Fit a screwdriver in the spring shaft and turn it until the desired tension is provided.

Adjusting the stitch length

Turn stitch length dial counter-clockwise to bring the desired value to the top of the dial so that the value is aligned with the pin.
Reverse feed stitching

1. The machine performs reverse feed stitching as long as the lever is held depressed.
2. The moment you release the lever, the machine resumed the normal stitching mode.

Adjusting the pressure of the presser foot

Pressure to fabric can be adjusted by turning the pressure-adjusting screw.

• Adjusting the presser foot and the walking foot
• Loosen not 1, and change the position of the cam rod boss accordingly.
• Highest position—The stroke is maximized. “A”
• Lowest position— The stroke is minimized. “B”。
• Alternate vertical motions of the walking foot and presser foot The alternate vertical strokes of the walking foot and presser foot
• Loosen screw ② of the top feed crank..
• Bring the thread take-up lever to its highest position, and lower the presser bar lifting lever. Move top feed crank ③ to left“A”to increase the stroke of the presser foot, or to the right“B” to increase it.

The timing between the rotating hook motion and needle motion

1. Set the feed length (stitch length) to “6” on the feed setting dial.
2. When the needle is lifted 2.4mm from the lower dead point, as shown in Figure, the following positional relationship should be maintained.

• The upper edge of needle eye should be 2.3 mm below the hook point.
• The hook point should be located at the center of needle axis.
• Gap between the hook point and the side face of needle should be 0.0.5mm.

Relationship between hook motion and opener motion

1. Turn the balance wheel by hand and stop when the opener holder is located most remotely from the throat plate.
2. Make sure gap between the bobbin case holder A and the opener is approximately 0.2 mm.
3. If the gap is too large or small , loosen the opener holder set screw B and adjust position of the opener.

Relationship between needle motion and feed dog motion

1. Set feed length to “0” on the feed setting dial
2. Set the needle at the lowest position.
3. Lean the machine head backward, remove the back cover, loosen screw B and C.
4. Adjust the distance between presser rod and vibration prevention rod to 9 mm.
5. After the completion of adjustment, fully tighten the screws B and C.

Note: At this time make certain that needle can enter the feed dog needle hole at the center of the hole.

Adjusting the height of the feed dog
The max. Height of the feed dog from the surface to the needle plate is normally 1mm. To adjust this height:

1. Set the stitch length at minimum.
2. Turn the pulley so as to raise the feed dog to it highest position.
3. Loosen the screw“A”, adjust the height of the feed dog .
4. Tighten the screw“A”after adjustment.

Safety mechanism

If the thread is caught in the hook while the sewing machine is in operation, the safety mechanism actuates to idle the lower sprocket only if the thread is caught in the hook while the sewing machine is in operation, the safety mechanism actuates to idle the lower sprocket only.

1. How to reset

• Remove the thread caught6 in the hook
• Pressing push-button ①, strongly turn the pulley in the direction opposite to its normal rotational direction.

Safety load

Turn adjustment screw ② in direction“A”(clockwise) to increase the safety load, or in direction “B” (counter-clockwise) to decrease it.

Adjustment of needle bar stop position （GC2268-2BL）

1. Adjust of “UP”position When the pedal is kicked down by the heel, the machine stops at the “UP” position. If the marks deviate larger than 3mm, adjust as follows.

• Disconnect the plug of the cable from the machine head.
• Run the machine and stop at the “UP” position.
• While holding the pulley, insert the “adjusting tool” in hole “A”, then remove the tool.

Adjust of “DOWN” position

When the pedal is “Neutral” the machine stops at the “DOWN” position. If the marks deviate larger than 5mm, adjust as follows.

• Disconnect the plug of the cable from the machine head.
• Run the machine and stop at the “DOWN” position.
• While holding the pulley, insert the “adjusting tool” in hole “B”, then remove the tool.

Confirm the stop operation, then set the plug coming from the machine head into the receptacle.

Regulate the atmospheric pressure （GC2268-2BL）

When the air cylinder works normally, the necessary atmospheric pressure is 5~6bar. Can find out through the dial plate of the filtering.
