3. Installation and preparation
1) Placement of the machine
To ensure smooth vibration free operation, the machine should be placed on an even and firm floor.
Placing the machine stand on a rubberized mat is recommended to further reduce the noise and
vibration.
2) Installing drip pan (Fig. 1). Fix drip pan (1) into the table cutout, aligning knee lifting rod (3) with knee lifter
connecting rod (15) of machine head, so they touch, also make sure dimensions are at 30 and 119.5mm from nail
hole to the table, (as depicted in Fig. 1) then drive nails (2) into both sides of the cutout to secure the drip pan. (See
figure on 9 of parts book).
3) Mounting machine head (Fig.2)
Hinge A on machine head should align with hinge socket B on the table, move the machine head carefully until
it is firmly in place on the frame of table cutout.
4) Mounting rock shaft bracket of knee lifter (Fig.3, also see figure in chapter 9)
1. Adjust rock shaft knee plate (18) so it is comfortable for the machine operator to use.
2. Adjust the position of knee lifter assembly following Fig. 3, then fasten the rock shaft bracket (7) with wood
screws (6).

6) Connecting the clutch lever to the pedal (Fig. 5)
1. The optimum tilt angle of pedal (A)
to the floor is approx. 15 degree.
2. Adjust the clutch on the motor so that clutch lever C and draw bar B run in line.
3. The machine balance wheel should rotate counterclockwise for normal sewing (G). The motor rotates in the
same direction. The rotation can be reversed by simply turning the plug on the motor over.
4. Adjust the tension of the 0-belt (F) by moving the motor vertically up or down. The proper tension of the V-belt
is relatively slack. When the belt is pushed at the belt span the give should equal about % to 5/8 of an inch.
7) Installing the bobbin winder (Fig. 6)
Align pulley (B) on bobbin winder with the outside of belt C. A uniform amount of clearance must be constant so
the pulley remains in contact with the belt even after it stops running. Using the thumb latch lever (A) to push the
bobbin winder wheel in place drives the bobbin winder while the machine is running. Make sure the bobbin
winder is aligned with the slit (E) in the sewing machine table before running the machine. The bobbin winder is
fastened to the table with two wood screws (D).
В A :
8) Installing the spool stand (Fig.7)
Install spool stand at the right rear corner of the table. Make sure that the stand doesn’t obstruct the machine.
Secure the stand in place by tightening wood screws (C).
2. Preparation
1) Cleaning the machine
Before delivery, the machine parts are coated with rust preventive grease, which may have hardened
during storage and/or shipment. This grease must be removed with a clean cloth and a solvent.
2) Examination
Though every machine is sewn off and subjected to a detailed inspection before delivery, the machine
parts may have loosened or come undone during shipment. A thorough examination must be
performed after cleaning the machine. Turn the balance wheel to see if there is an obstruction,
resistance or any abnormal noise. If any of these situations are present, adjustments must be
made before running the machine. |
3) Lubrication
Before running the machine, clean it with a soft cloth, then fully lubricate at the points indicated by
the arrows shown in Fig 8 and Fig 9. If the machine is continuously operated, the operator should
lubricate it no less than twice a day. Be sure to use #8 Sewing Machine Oil or #7 Machinery oil.

The bevel gear cases in Fig. 12 and Fig. 13 are packed with lubricant and it should be re-applied
periodically as it will dissipate gradually after a long period of use. When you replenish undo the screw
plugs L & K first then apply with fresh lubricant through screw hole into gear cases then re-insert screw
plugs. Should the lubricant in the bevel gear cases be too dirty or hardened, it must be changed.
4) Trial run
À trial is imperative with a new machine or if the machine has not been used for an extended period of
time. Before you begin, lift the presser foot to make sure that the balance wheel is turning in the right
direction. Begin by running the machine at a low speed. If the machine is running smoothly increase the
speed gradually until you reach 2000 spm. Run at this speed for a few minutes. The machine is now
ready to use.
4. Operation
1. Thread selection
Needle thread should be left-twist thread. For bobbin thread, either left or right twist thread is
may be used. To identify the twist direction of the thread, hold the thread as shown in Fig. 13; twist the
thread with the right hand in the direction of the arrow. If the thread tightens, the thread is left-twist
thread otherwise the thread is right—twist.

Fig. 15
4. Winding the Bobbin thread
1) Directions (Fig. 16)
Install bobbin (A) onto bobbin winder spindle (B). Pass thread (C) from spool through the eye (1) on
tension bracket (E) pass it between tension discs (2) and then wind the end of the thread a few turns
on the bobbin. Push stop latch thumb lever (D) down to lock the bobbin. The winder pulley (F) is now
engaged by belt (G). Start the machine. Please note when thread is wound without sewing
be sure to keep the presser foot lifted. When the thread is fully wound, the bobbin winder
stop latch automatically releases the bobbin winder and A stops it.
2) Winding adjustment (Fig. 17)
The bobbin thread should be neat, tight and uniform. If not, adjust the tension by turning
tension stud thumb nut (A) on bobbin winder tension bracket. When the thread layer
does not present an even, cylindrical shape, loosen tension bracket screw (B) and move tension
bracket (C) left or right. If thread is wound as shown in Fig, 17b, move the tension
bracket right, if thread is wound as shown in Fig. 17¢, move the tension bracket
lett. After adjusting the tension bracket to your needs, tighten screw (B).
Note: nylon or polyester thread should be wound with a light tension; otherwise bobbin (D) might break.
Do not over fill the bobbin, for optimum performance the capacity of the bobbin should be at about 80%.
5. Threading the needle and drawing the bobbin thread
To thread the needle, raise needle bar to its highest position, pull thread from the spool and pass it in the
numerical order depicted in Fig. 18. (1) Pull thread from spool, pass it through the guide plate (1) at the top of
the machine, then thread it between the thread tension discs, and thru the left hole of guide plate(1). Continue
through three-eyed thread guide (2). (3) Pass thread between thread tension discs (3). Pass upward thru thread
take-up spring (4) and thread guide (5) and (6) then pass it through the thread take-up lever (7) from right to left.
(5) Pass it down thru thread guide (8), (9) of needle bar bushing (lower) and needle bar thread guide (10). Then
pass it from the left through the needle eye (11), once threaded pull out approximately 3 inches of thread. To
draw up the bobbin thread, hold the end of the thread, turn the balance wheel to lower the needle bar and then
continue until it reaches its highest position. Pull the needle thread and the bobbin thread will follow. Pull the
ends of both threads towards you and under the presser foot.
6. Inserting the bobbin (Fig.19)
1) Put the bobbin B into the bobbin case A.
2) Pass the thread E thru slit C to lead it underneath
the bobbin case to the tension spring D and out at the notch of the spring, pull the thread out about
2”.
Note: Make sure that the bobbin rotates clockwise when the thread E is pulled. If not, turn to
another side of the bobbin B and try again.
7, Installing the bobbin case (Fig. 20)
Lift the needle bar to its highest position and open the bed slide. Lift the bobbin case latch lever A and
holding it, securely install the bobbin case into the rotating hook B. Note that the bobbin case latch is
engaged in the positioning groove of rotating hook spindle. When removing the bobbin case from the
rotating hook, lift the bobbin case latch lever A completely and holding it by the fingertips to prevent
the bobbin from dropping out of the bobbin case, then gently remove the bobbin case.
8. Setting stitch length and reverse sewing (Fig. 21)
Stitch length can be set by turning stitch length regulating dial (1). The stitch length increases when
you turn stitch length regulating dial (1) counter clockwise, and the stitch length decreases when you turn
the dial (I) clockwise. Sewing reverses when feed reverse lever (2) is depressed, and forward sewing
resumes automatically when the feed reverse lever is depressed once more (2).
9. Presser bar height positioning (see Fig 22)
Loosen lock nut E and screw A, remove the rubber plug on face plate B, loosen screw C, set the position
of presser bar (6.5mm from the surface of throat plate to the bottom of presser foot as presser foot at its
highest) tighten screw put on rubber plug, tighten screw A and lock nut B.

10. Adjusting the pressure of presser foot (Fig. 23)
Pressure on presser foot is to be adjusted in accordance with material to be sewn.
Loosen lock nut A first, then turn pressure regulating thumb screw as shown in Fig.23 to increase the
pressure while turn the pressure regulating thumb screw in direction of arrow B to decrease the pressure
on presser foot, then tighten lock nut A. The proper pressure should be that the material can be pushed
normally.
S. Adjusting thread tension
In principle the thread tension should be adjusted in accordance with fabric and thread being used as
well as other factors. In practice, the thread tension is adjusted according to the stitches that result. The
needle thread tension should be adjusted in relation to the bobbin thread tension. To adjust the bobbin
thread tension, turn bobbin case tension spring screw A (see Fig. 24) clockwise to increase the tension, or
turn the screw counter-clockwise to decrease the tension.
It is common practice to check the bobbin thread tension as shown in Fig. 25. In case of coated thread
hold the end of the thread and move bobbin case up and down, if the thread unravels slowly, the tension
level is fine.
The needle thread tension can be adjusted by changing:
(1) tension of the thread take-up spring,
(2) swinging range of the thread take-up spring,
(3) tension of thread tension spring
(4) the position of thread guide and thread tension discs. Instructions on theses steps follow.
©. Figs
1. Adjusting the thread take-up spring
The normal tension of the thread take-up spring is approx. 25-35g. The normal swing range of the
thread take-up spring is 5-8mm. For sewing light weight materials (with a short stitch length), lessen the
spring tension and widen the range of the spring. For sewing heavier weight materials, strengthen the
spring tension and shorten the range of the spring.
(1) Adjusting the thread take-up spring tension (Fig. 26)
Loosen tension stud set screw A, turn tension stud B clockwise to increase the spring tension, or turn
the tension stud counter-clockwise to decrease the spring tension. After the adjustment, be sure to
tighten tension stud set screw A. 2°
Fig. 26
The thread take-up spring tension is about 30g. To attain this, loosen set screw A first, then turn tension
stud B counter clockwise to release the tension of thread take-up spring C to zero. Turn tension stud
B counter-clockwise until spring C just comes into contact with the stopper on thread take-up spring
regulator, then turn tension stud B clockwise by another 1 /2 turn. After adjustment, tighten tension stud
set screw A.
(2) Adjusting the swing range of thread d take-up s; spring 2 (Fig. 27). |
Loosen set screw B, turn tension complete C clockwise to increase the swing range or turn it counter-
clockwise to decrease the swing range. Before delivery, thread take-up spring is properly adjusted.
Re-adjustment is needed only in the case of sewing special materials or with special thread.
2. Adjusting the thread guide
The position of the thread guide affects the sewing quality and must be adjusted according to the
materials being sewn and sewing conditions. The normal relationship between the position of the thread
guide and the materials to be sewn is illustrated in the following table.
Material weight “Heavy ~ Medium 22)
3. Adjusting the tension of needle thread and bobbin thread
Fig. 28 shows the various types of stitch patterns. Normal stitches should appear as shown in Fig. 28(a).
When stitches are puckered, loose, or the thread breaks, the tension of needle and bobbin thread must be
adjusted accordingly.
1) If the needle thread tension is too high or bobbin thread tension is too low, turn the tension regulating thumb
nut counterclockwise to decrease the needle thread tension or tighten the bobbin case tension regulating screw to
increase the bobbin thread tension (see Fig. 29).
2) If the needle thread tension is too low or bobbin thread is too high, turn the tension regulating thumb nut
clockwise to increase the needle thread tension or turn the bobbin case tension regulating screw counter-
clockwise to decrease the bobbin thread tension (see Fig. 30).
3) If the stitches appear as shown in Fig. 28(d), (e), adjustments can be made by following the above steps.
6. Machine Adjustment
Timing between needle and rotating hook motion
1) Adjusting the needle bar position (Fig. 31)
Turn the balance wheel to position the needle bar, C at its lowest position. Remove the rubber plug from
the face plate, A. Loosen needle bar C connecting stud clamping screw B. Move needle bar C vertically to
bring the center of needle eye, D match up with the inside surface of rotating hook E. Then tighten
~~ clamping screw B and replace rubber plug.
2) Adjusting rotating hook point timing with needle (fig. 33)
Turn the balance wheel to position the needle bar at its lowest position, and when the needle bar is
lifted again at 2.5 mm from its lowest position, the rotating hook point D should coincide with needle
center line C, and hook point D should be 1.2mm above the upper edge E of needle eye.
Fig. 33
When adjusting the rotating hook point timing also note that the clearance between the notched bottom
of needle D and hook point C must be constant at approximately 0.05mm (see Fig. 34).
Fig. 34
3) Removing and installing the rotating hook (Fig. 35) |
Lift the needle bar to its highest position. Remove the throat plate and take out the needle and the bobbin case.
Loosen rotating hook bobbin case holder position bracket screw C and take down position bracket A. Loosen
the two set screws D on rotating hook. At this point, the hook will turn freely on its shaft, and it can be kept
from colliding with the feed dog support since the feed dog support is at its highest. Remove the rotating hook
slowly. To install the rotating hook follow the above sequence in reverse.
2. Adjusting the feed dog
1) Adjusting the height of the feed dog
Turn balance wheel to raise the feed dog to its highest position, at that position, the height of feed dog
teeth should be 0.8-1mm above the throat plate surface. If the height of the feed dog teeth islmm
above the throat plate surfaces it is the ideal height for sewing heavy material.
era 0.8mm~ Imm
When adjusting, loosen feed lifting rock shaft crank clamping screw A (Fig. 36) slightly, then turn feed
lifting rock shaft crank B ull the * proper rasa © of the feed dos teeth is achieved, after adjustment, tighten
clamping screw A. © AT
Fig. 36
2) Adjusting the position of feed dog (Fig. 37) The standard position of feed dog A is that the clearance from
the throat plate slit end to the front end of the fully advanced feed dog is 1.5 mm.
2) Max the feed dog to the position where the feed dog fully advances. Loosen two feed rock shaft crank clam
ping screws. Move feed dog support to adjust the clearance between the feed dog and throat plate. After adjust-
ment, tighten clamping screw.
3 Adjusting the tension release mechanism (Fig. 38)
The tension discs should be pushed apart to open when the presser foot is lifted. But the open timing of the
tension discs can be adjusted. Remove the rubber plug at the rear of arm and loosen screw A of the knee lifting
lever (left). Then the tension releasing cam can be moved left or right, open later when the cam is moved right,
open earlier when the cam is moves er
