4. LUBRICATION
1. Lubrication oil and cooling oil:
Please use Garudan m22, Mobil #10 or equivalent oil for lubrication oil and use silicone oil for cooling
oil.
2. Feeding oil:
The lubrication oil has been drained off completely before delivery, adding oil to the upper line of oil
gauge (c) by removing seal plug (a). Also, please make sure the oil flows out of nozzle (b) at the start
of operation.
Before starting a brand new machine or a machine which has not been used for more than a couple
of weeks, lubricate the needle bar first. Before using the machine, check the oil level is above the
mark L

4. Oil filter:
Although the machine is using oil pump lubrication and splashing lubrication systems, please check
and clean oil filter every month. And when no oil or very little oil comes out of nozzle even indicator
shows normal, please check oil filter and replace it if necessary.
5. Adding cooling oil:
Avoid needle breaking, stitch jumping or thread melting problems etc. Please fill cooling oil tank and
felt with silicone oil under some special circumstances, cannot use silicone oil or no need to use
silicone oil then, you can take felt off from.
5. NEEDLE
1. Needle selection:
Needle UY128gas of Groz Beckert is to be used. There are many sizes of needle according to the
thickness and kind of fabrics used.
2. How to replace the needle:
Replacing needle should be made correctly with the scarf facing rightly backward as shown in the
illustration.

3. Threading:
Threading should be made correctly referring to the illustration. Improper threading might cause skip
stitch, thread breakage and uneven seam etc. The threading for three needle machine is shown in the
illustration below. For two needle machine, threading is the same except only two needle threads.
A, B, C – needle thread D – top cover thread E – looper thread

6. PROPER OPERATION ADJUSTMENT
Due to the thickness of fabrics, different materials different kinds of thread, Different stitch
requirements the changes of differential ratio, all is affecting the sewing performance. Thus, must
conduct the proper operation adjustment in order to get best sewing effects.
1. Pressure of presser foot:
To increase the pressure of presser foot, turn adjusting screw (b) clockwise after loosening lock nut
(a) and to decrease, turn it counterclockwise. Pressure of presser foot should be as weak as possible
so long as presser foot can operate properly.
2. Thread tension:
Different threads have different tensions and even same threads will have different tensions when go
through different threading holes. Each thread tension can be adjusted by individual tension nut to
increase thread tension, turn tension nut clockwise, to decrease thread tension, turn tension nut
counterclockwise. Please use least thread tension as long as it will not affect the sewing effects.
3. Adjusting stitch length:
Adjustment of stitch length can be made steplessly from 1.4mm/per stitch to 3.6mm/per stitch.

4. Stitch length adjustment:
Turn hand wheel. One graduation on the Circumference of hand wheel indicates a stitch length (m.
m). Which should be aligned with the mark (B). Then release hand.
5. Adjusting the needle thread take-up:
Different threads have different stretch tension and cause skip stitching thread breaking and
unstable stitching easily. This machine equipped with thread take-up, front needle thread guide, rear
thread guide and auxiliary thread tension control guide in order to give letter control of the looper
thread take-up and stabilize the stretching of looper thread.
The thread take-up and rear thread guide were set at standard position before shipment. As shown
on figure A/B. And also can be adjusted as arrow directions if necessary
Fig. A Fig. B

MP03400EN_181010 14
Sometimes, it is not so easy to make loop for some kinds of thread and also make it difficult for
looper to catch the needle thread, causing skip stitch. In such case, can use auxiliary thread tension
control guide to stabilize the threads (Fig. C)
Fig. C Fig. D
In case the formation of needle thread loop is unstable when using stretchable thread, you can solve
this by adjusting the height of front needle thread guide, especially when looper move from right to
the left. If the left needle skip the stitch when using synthetic thread or right needle interfere with
the formation of thread loop when using blended thread, you can use front needle thread guide,
with needle bar at the lowest position, the center of thread hole of rear thread guide eyelet should
be even with the surface of front needle thread guide and front needle thread guide and rear thread
guide should be parallel with each other (Fig. D)

6. Adjusting the looper thread take-up:
When left needle comes down to the half point (Fig. E), the thread must get off from the highest
position of looper thread take-up. The adjustment is made by loosening screw, turn the looper
thread take-up to the proper position and tighten the screw (Fig F).
Fig. E Fig. F
To decrease the amount of looper thread in the seam move thread guide eyelet to
Aligning mark to increase, move it backward (Fig. G)
For stretchable threads, move right and left thread guides to aligning mark and also do not pass the
thread between thread guide.

7. Adjusting spreader thread take –up:
The thread amount of top cover thread is adjusted by spreader thread take-up. For standard
position, loosening set screw, push thread guide upward to its highest position as x direction show.
Then tighten the set screw.
Stretchable thread, push the thread guide downward as y direction and thread must pass through
the eyelet of thread guide.
7. ADJUSTING OF MACHINE
This machine was sent to the standard position before delivery and it's unnecessary to re-adjust
unless under some situation as changing the needle, looper, different kind of fabric or different
sewing threads. Please adjust according to following items:
1. Adjusting presser foot and petting the height of presser foot:
It will be easier to conduct some adjustments by taking off the presser foot as follows:
Loose the lifter arm and loosen the screw from presser foot and stopper, lifting up the presser bar,
you can take presser foot very easily. After changing, remember put it back in reverse sequence (Fig.
A, B).

2. Adjusting the height of needle bar and needle drop point:
When the tip of looper comes to the center of left needle, the looper should
Position above the upper end of needle eye by 0.5-1.0 mm as this is the standard
Position for needle bar (Fig. C).
Loosen the screw of needle bar clamp and adjust the needle bar to get proper height (Fig. D).
After adjustments, tighten the screw of needle bar clamp and make sure the needles are in the
center of needle drop hole of needle plate (Fig. E).

When the tip of looper meets the center of left needle. The clearance between them should be 0.2-
0.3mm. When the tip of looper meets the center of middle needle. The clearance between them
should be minimal. When the tip of looper meets the center of right needle. Giving the clearance of
0-0.05 mm between the tip of looper and needle by pushing rear needle guard 0.2-0.3 mm against
the needle. The adjustment is made by loosening screw of looper holder.

6. The relation between needle and real needle guard:
6.1 Setting the height of rear needle bar:
When needles descend to the lowest position. The ridge line (A) of rear needle guard (B) align with
the center of the eye of each needle. The adjustment of the height of rear needle guard is made by
loosening the screw (Fig. I).
6.2 Setting the angle and timing of rear needle guard:
When the tip of looper passes the center of right needle. The rear needle guard will slightly push the
right needle forward about 0.2-0.3 mm. And at this time, the clearance between looper and right
needle is 0-0.05 mm and looper will touch middle needle slightly and the clearance between looper
and left needle is 0-0.05 mm. These adjustments are made by loosening the set screws (C) and (D),
(Fig. J, K).
Fig. I Fig. J Fig. K
7. The relation between needle and front needle guard:
7.1 Setting the angle and timing of front needle guard:
When the tip of looper comes to the center of left needle and right needle, adjust the clearances
between those needles and front needle guard should be 0 - 0.3 mm. The adjustments are made by
loosening set screw (E) and move front needle guard to its proper position. Then, tighten the set
screw (E), (Fig A).
