2.	Features
*The extensive design of various components and lubrication system and also the addition of the needle
cooler device on this machine assure the normal operation of maximum high speed of 6,000 stitches								per	~
minute,		without any troubles.
*The upper knife is flat-shaped to make the carbide tip promises long durability of. the knife.
*Stitch		can be easily regulated by push-button,	with the scale on the		face plate,	thus it is	unnecessary
to change the eccentrics when you would like			to change	the stitch length.
* Differential feed can be easily adjusted by the lever for				gathering	or stretching without		soiling	your
hands.		This also applies for the instantaneous	differential	adjustment	obtainable.
* Ample space on the cloth plate allows easy sewing operation.
*Oil	level in the oil reservoir is shown on the		special oil gauge on the front side of the machine.
*Lubrication can be easily checked through the oil window in the top cover.
*Optional needle cooler ensures perfect sewing operation even with synthetic materials and threads at								the
high speed of 6,000 stitches per minute.
*Colour combination of TAN-BEIGE is in well harmony with your modern factory,						and operator's fatigue
can	be	lessened.

3.Operation

A.Sewing speed

Maximum speed of this machine is 6,000 stitches per minute. For the first 100 actual working hours, ho~vever, the new machine should be operated at about 5,000 s.p.m.:so that all the working parts are well run-in. After this running-in period, you may operate the machine at maximum speed of 6,000 stitches per minute. This is desirable for machine's long life.

B.Motor, motor pulley and belt

1)Use a clutch motor, l/2 Hp, 2 pole, single or three phase. Our motor available is Models MD-344 (single phase) and MD-354 (three phase).

2)Use M -type V-belt.

3) Machine speed (s.p.m.),	diameter of motor		pulley and length		of· motor belt is		related to the follow-
ing table.
		Outside diameter of pulley and length of V-belt

In the case to require larger gathering differential feed.

Remove cloth plate and feeding mechanism cover, loosen nut ~ of main feed link shaft by an attached wrench, then lower downwarcl (Fig. 23B) \Vhen the main feed link shaft is lowered until bottoming.

(Fig.23B)	4. Adjustment
	1)	Underlooper height
! c---~	~-	The underlooper's height can be fixed by inserting the underlooper
2m-T--------------		all the way into the looper holder.
(Fig.24)	2)	Underlooper tilt
		Attach the underlooper aslant as shown ,in Fig. 24.
	3)	Underlooper vs. needles
		a. Needle	drop
		Adjust	needle drop by means of the needle clamp so the right
		needle is 0.2- 0.3mm away from the left needle in your direction.
		(See Fig. 25).

(Fig.25)

b.. The leftmost position of underlooper

When the underlooper is moved all the way to the left, its point must be 4mm to the center of the left needle. (See Fig. 26).

.4mm from center of left needle

From the library of: Superior Sewing Machine & Supply LLC

c.Needle height

Set the needle height so when the point of the underlooper meets the center of the left needle in its upward stroke, the underlooper point is about 1mm above the needle hole, (See Fig. 27).

(Fig.27)

Left needle 11 mm above pop of needle plate

~"'"""-"'-~ ~ j

(Fig.28)

Clearance between and underlooper point

should be 0.05-0.1 mm when point is at center of left needle.

(Fig.29)

Thus	adjusted, the highest position of the needle will be as
shown	in Fig. 2H.

d. The forward and backward positions of underlooper holder.
Set the forward and	backward positions	of	the	underlooper	~
holder with the point	of the underlooper in	line	with	the center

of the left needle in its rising stroke. When the })older positions are set as sho\\-11 in Fig. 29, retighten the holder set screws securely.

4) Attaching the movable needle guard

One	of the	two	needle guards moves with the underlooper. Attach
it _as	shown	in	Fig. 30.

(Fig.30)

From the library of: Superior Sewing Machine & Supply LLC

Adjust the needle guard so the clearance between the underlooper point and the left needle is 0.05-0.1 mm when the underlooper point is in line with the center of the left needle. Bend the needle with movable needle guard for this adjustment. (Fig. 31 ).

5) Attaching the fixed needle guard

This needle guard serves as an auxiliary and is to be fixed to a clearance of 0.3-0.Bmm as shown in Fig. :32. Never reduec the

clearance to zero.

(Fig.31)

	6)	Positioning the overlooper
		This machine is so designed that two kinds of sewing Four-thread
		overlock and Mock safety are available by simply relocating the
		overlooper holder assembly and holder guide assembly.
Fixed	needle guard	a. Four-thread overlock (See Fig. 33).
		Loosen the		set screw (A), move the holder guide					assembly	all
		the way to the left, and fix it securely with the set screw (A).
		Then loosen the set screw (B) for the overlooper holder assem-
(Fig.32)		bly, adjust		the height of the overlooper, and fix it with the set
		screw( (B)		again.		Finally, check the		relationship	between	the
Move holder assembly		underlooper and the needle. (See Fig.						34).

0
		Adjust the underlooper height in the same way as above, and
		check	the	relationship			between the underlooper and the needles.
	.. (A)	Note: The holder guide assembly has been carefully positioned in the
		machine assembling process, and its set serew is painted red
		to	seal	it.	You are		advised not to relocate the		assembly.
