Replacing the oil and the oil elementReplacing the oil and the oil element
Replacing the oil and the oil element
To extend machine life, be sure to replace the oil
after the first 250 hours of operation.
To replace the oil, follow the procedures below.
1. Remove the V belt from the motor pulley and
then remove the machine from the table.
2. Remove screw D and then drain the oil.
Be careful not to stain V belt with the oil.
3. After draining the oil, be sure to tighten screw
D.
4. Fill the machine with oil by referring to 3-2
shown above.
If element E is contaminated, proper oiling may not
be performed. Clean the filter element every six
months. If just a little or no oil flows out from the
nozzle with the proper amount of oil in the machine,
check the element. To do so, remove oil filter cap F.
Replace the element if necessary.

0.2mm.
Then the looper should barely touch the right needle
(approximately 0.2mm). On 3-needle machines, the
clearance between the point of the looper and the middle
needle should be 0mm. To make the above adjustment,

When the looper moves around the needles, the point of
the looper on 2-needle and 3-needle machines barely
touches the right needle and the clearance between the
point of the looper and the left needle is approximately
0.2mm.
To change the looper's orbit,
1. Loosen screw B on eccentric A.
2. Shift the timing mark by moving eccentric A front
or back.
The timing mark is factory-set for standard.
Do not change the orbit extremely.
■
The timing mark is at the standard position.
The 3 o'clock end of the orbit is at a slightly up
position.
■To advance the timing of the looper to the needle
Shift the timing mark to X. Skip stitching may occur when the looper moves to the right.
A thread chain is not produced smoothly.
■To delay the timing of the looper to the needle Shift the timing mark to Y.
Skip stitching may occur when the looper moves to the left.
The needle extremely touches the back of the looper, causing needle breakage.

The clearance between the point of the left needle and
the back side of the looper when the looper moves to
the right from the extreme left end of its travel should
be 0.05 -0.1mm. The clearance between the point of
the right needle and the back side of the looper should
be 0.2~0.3mm. The amount of the looper front-to-back
movement is factory-set properly for needle counts
9~11.
If you use needle counts 12~14, adjust the amount as
required (see below).
1. Remove rear bed cover A.
2. Loosen the nut on the looper front-to-back rod pin.
To decrease the amount, move the rod pin to X.
To increase the amount, move the rod pin to Y.
The amount range is from 2.3 to 3.1mm.
The amount is factory-set at 2.7 to 2.8mm.
Adjust according to the needle count.
If the amount is excessively decreased, the needle will
rub against the back of the looper, causing needle
breakage. If the amount is excessively increased, the
clearance between the needle and the back of the
looper will increase and then skip stitching may occur
when the looper moves to the left.
< Note >
To sew under good conditions, adjust the looper orbit after
changing the amount of the looper front-to-back
movement by moving the timing mark slightly to X or Y.

looper has reached the center of the left needle, make sure
the left needle does not touch the looper by pressing the
left needle backward. Then turn the needle guard (rear)

The timing of the needle thread take-up in relation
to the up-and-down movement of the needles can be
adjusted. This timing is factory-set to synchronize
with the up-and-down movement of the needle bar.
< Note >
The rod ball is factory-set at 5.5mm from the rear end
of the shaft. To make the needle thread loop small,
move the rod ball to the front.
To make the needle thread loop large, move the rod
ball to the back. Remove the rubber top plug.
Loosen the screw of (A) with a 5mm wrench.
Then move the rod ball to the front or back.

To increase the amount of the looper thread
supplied by the looper thread take-up, loosen screws
of thread guides B and C and move the thread
guides to the front. To decrease it, move the thread
guides to the back. Adjust according to the thread

Thread guide D should be at the center of the groove of
looper thread take-up A. When the point of the left
needle has reached 0.5~1mm above the bottom surface of
the looper blade while the looper is moving from the
extreme left end of its travel, the looper thread should be
removed from position C on the looper thread take-up.
To make this adjustment, loosen screw B and adjust the
looper thread take-up. To adjust the height of thread
guide D, loosen screw E and then align the bottom of the
slot of thread guide D with the top surface of the bracket.

To adjust the feeding amount of the lace / elastic, loosen
wing nut A and turn adjusting screw C while checking the
readings on lever B. To increase the amount, turn screw C
clockwise. To decrease the amount, turn screw C
counterclockwise. Adjustable from 0.9 to 2.3mm. Adjust
according to the fabric and/or elastic to be used. Adjust the
pressure of the elastic feed small roller (see 11-6)
simultaneously.
To increase the amount a little more, loosen two eccentric
set screws from hole D. Turn the handwheel all the way to
MAX with the wrench inserted until the handwheel stops
and then tighten the set screws. This increases the
adjustable range from 1.4 to 3.6mm.

7 Checking the performance of the elastic feeder
the performance of the elastic feederthe performance of the elastic feeder
the performance of the elastic feeder
If the elastic feeder does not work well, it will not feed elastic uniformly, causing various
kinds of trouble such as burned elastic, jammed elastic, needle breakage, uneven sewing.
Check the following.
1. Adjust small roller A so that it can turn easily.
If it does not, the tape cannot be fed neatly.
2. The roller link and its shaft should move smoothly.
3. The small roller spring pressure should be as light as possible, yet be sufficient to
follow the roller speed.
< Note >
Decrease the pressure for stretchable lace elastic.
Increase the pressure for non-stretchable lace elastic.
