Attention

This instruction manual is designed mainly for technicians, but it is advisable that also operators read the instructions with mark to use the machine properly.
◇The numbers in lower left corners of figures are figure numbers. We use them in texts as needed for your reference.

Attention

The description in this instruction manual is subject to change for improvements of the commodity without notice.

1. Sewing speed and rotating direction of pulley

Refer to Table 1 for maximum sewing speed and standard speed.

Run a new machine at speed about 15 - 20% lower than maximum speed during the first 200 hours (for about one month) so that a machine can offer a long service life in good condition.

The rotating directions of the machine pulley ① and the handwheel ② are clockwise as shown in the figure.

CAUTION

If rotated in reverse direction, oil cannot be supplied properly. It can cause the damage to the machine.

F: Looper thread

Needle thread

Pull out the thread until it is in front of the needles. Then, cut off the knots before needle eye to rethread.

Thread correctly for the left needle in the inmost position as shown in the figure.

Looper thread and Top cover thread

Pull the thread until the knot is out. Then, cut off the knot.

3.4 Removing presser foot and presser foot lift

Removing presser foot

(1) Loosen the screws② of the lifter lever stop①, the screws ④ of the collar ③, and the screw ⑧ of the presser foot ⑦.
(2) Push down the lifter lever ⑤ to remove the presser foot ⑦.

Adjusting height of presser foot

(1) Push down the lifter lever⑤ to make the height from the top of the stitch plate to the bottom of the presser foot to the value of M in the Table 4.
(2) Tighten the screws ② securely.
(3) With keeping that, make the clearance between the end of the presser bar bushing⑥ and the top of the collar③ to 0.2 mm.
(4) Tighten the screws ④ securely.

After adjusting, push down the lifter lever ⑤ fully to check the height of the presser foot.

Presser foot lift depends on the needle distance.

3.5 Looper

3.5.1 Installing angle and height of looper

Insert the looper① into the looper holder② fully and tighten the screw ③ securely.

It makes the height and installing angle ( 0^ ).

3.5.2 Distance between looper and needle

The distance between the looper tip and the center of the right needle is 2.7-2.9mm, when the needles are in the lowest points, and the looper ① is in the extreme right.

Loosen the screw ④ to adjust it.

NOTE

The distance between the center of the needle bar and the looper ① tip is 6.0 mm even if the needle distance changes.

2.7-2.9 mm ④

i Supplement

The timing gauge (No. 3200262) makes it possible to adjust the distance easily.

The gauge is an extra part. Place an order from our agents or directly from us.

3.5.3 Using timing gauge

Move the looper at the extreme right. Keep fitting the right needle into the groove "V" corresponding needle distance, and fit the looper tip to the gauge.

Then, tighten the screw ④ securely. (Fig. 12)

3.6 Height of needle bar

Check points:

◇ Needles should be inserted fully into the needle holes of the needle clamp and fixed securely.
◇ Looper should be inserted fully into the looper holder and fixed securely.

Adjusting the height on the basis of looper:

(1) Install the needle to the left hole in the needle clamp.
(2) Check the looper is inserted into the looper holder fully.
(3) Turn the handwheel until the looper tip meets the center of the left needle.
(4) Loosen the screw① of the needle bar bracket. Move the needle bar up or down so that the looper tip passes 0.5 - 0.9 mm above the top of the needle eye.
(5) Tighten the screw ① securely. Check that the needles drop in the centers of the needle holes of the stitch plate respectively.

3.8 Needle and needle guard

3.8.1 Needle guard(rear)

Height:

When the needle is at the lowest point, Align the line “a” on the needle guard(rear)① at the lower part of needle eye of the extreme right needle.(Fig. 21)

Front-and-rear position:

(1)When the looper tip meets the center of the extreme right needle, make the clearance between them to 0 - 0.05 mm to push the needle guard(rear)① to the right needle.(Fig. 22)

Make the clearance between the left needle and the needle guard(rear)① to 0.05 - 0.1 mm.

Loosen the screws ②③ to adjust them.

(2)While lightly pressing retaining needle④ against needle guard(rear)①, the looper tip must come in contact slightly with retaining needle when the looper tip passes.(Fig. 23)

3.8.2 Needle guard(front)

The clearance between needle and the needle guard(front)① makes it approach without coming in contact as much as possible.

Loosen the screw ② to adjust it.

NOTE

Adjust a clearance properly so as not to shift, if needle comes in contact too much with needle guard (front), looper tip hits needle, and needle shift widely left, when looper moves from the right to the left.

3.9 Needle and spreader

Spreader

Make the clearance between the left needle and the hook "a" to 0.3 mm when the spreader① moves from the right to the left.

Make the clearance between the center of the left needle and the hook "a" to 1.5 mm when the spreader moves at extreme left.

Make the height from the top of the stitch palte to the bottom of the spreader ① to value M of Table 5.

Loosen the screw② of the spreader and the screw③ of the spreader holder ④ to adjust it.

NOTE

Adjust the height of the spreader so that the top cover thread passes behind the right needle and be caught by the left needle within adjustable range based on the needle distance.
