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.

The point of the looper should be 0.8~1.2mm above the

when it has reached the center of the left needle.
With the point of the looper at this position, set the
clearance between the left needle and the point of the
looper at approximately 0.2~0.3mm.
Then the looper should barely touch the right needle.
■On 3 -needle machines, the clearance between point A
of the looper and left needle C should be 0.2~0.3mm.
To make this adjustment, loosen screw D on the looper
holder first. Then adjust the needle guard (rear) so
that it presses right needle B slightly to the front.
With the needle guard (rear) and needle B in this
position, set the clearance between the point of the
looper and needle B at 0~0.05mm.
■On 2-needle machines, the clearance between point A
of the looper and left needle F should be 0.2~0.3mm.
To make this adjustment, loosen screw D on the looper
holder first. Then adjust the needle guard (rear) so
that it presses right needle E slightly to the front.
With the needle guard (rear) and needle E in this
position, set the clearance between the point of the
looper and needle E at 0~0.05mm.
< Note >
After the above adjustment, install the needle plate and
check to make sure each needle drops into the center of
each needle hole.
< Note >
When moving the looper holder front or back, be careful not to change the looper
setting distance.

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 0.2~0.3mm.
■The timing mark is at point E: standard
■When the timing mark is at point C, The clearance
between the point of the looper and the left needle
when the looper moves to the left decreases.
The clearance when the looper moves to the right
increases. Then the point of the looper touches the
right needle. Skip stitching may occur when the
looper moves to the right.
A thread chain is not produced smoothly.
■When the timing mark is at point D, The clearance
between the point of the looper and the left needle
increases. Skip stitching may occur when the
looper moves to the left. The needle extremely
touches the back of the looper, causing needle
breakage.
< Note >
To sew under good conditions, after changing the amount of the looper front-to-back
movement adjust the looper orbit by moving the timing mark slightly to C or D.
To change the looper's orbit, loosen screw B on eccentric A and 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 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 0.3~0.6mm (The needle is pressed
to the back). The distance between the point of the
left needle and the center of the looper's eye on the
back side of the looper should be 3~3.5mm.
■The amount of the looper front-to-back movement is
factory-set properly for needle count #11 (Nm75).
If you use needle counts Nm80~90, adjust the
amount as required.
■Remove the inside cover.
Loosen nut B while holding screw A for the looper
front-to-back adjusting pin with a screwdriver.
Then move the front-to-back rod front or back.
To increase the amount, move alignment mark D on
the front-to-back rod to the front from mark C on
the looper bar guide. To decrease the amount,
move mark D to the back. Adjust according to the
needle count.
< Note >
If you change the amount of the looper front-to-back movement, the clearance between
the point of the left needle and the back side of the looper when the looper moves to the

■When the point of the looper has reached the center
of the right needle, push out the needle guard (rear)
slightly toward you. Then there should be a
clearance of 0~0.05mm between the needle and the
looper. In addition, there should be a clearance of
0.05~0.1mm between the left needle and needle
guard (rear). Adjustment is made by loosening
screws (B) and (C). Be careful that the relationship
between related parts is not changed.
