1. PRECAUTIONS BEFORES STARING OPERATION

1) Safety precautions: .

(I) When turning the power on, keep your hands and fingers away from the area around/under the needle and the area around the pulley.

(2) Power nwst be turned off when the machine is not in use, or when the operator leaves the seat

(3) Power must be turned off when tilting the machine head, installing or removing the

"V'' belt, adjusting the machine, or when replacing.

(4)

Avoid placing fingers, hairs, bars etc., near the pulley, "V" _belt, bobbin winder pulley, or motor when the machine is in operation.

(5) Do not insert fingers into the thread take-up cover, under/around the needle, or pulley when the machine is in operation.

(6) If a belt cover, finger guard, eye guard are installed, do not operate the machine without these safety devices.

2) Precautions before starting operation:

(1) If the machine's oil pan has an oil smnp, never operate the machine before filling it

(2) If the machine is lubricated by a drop oiler, never operate the machine before lubricating.

(3) When a new sewing machine is first turned on, verify the rotational direction of the pulley with the power on. (The pulley should rotate counterclockwise when viewed from the pulley)

( 4) Verify the vol~ge and (single or three) phase with those given on the machine na.tnqJlate.

3) Precautions for operating conditions:

1) Avoid using the machine at abnormally high temperatures ( 35

·c

or higher) or low temperatures ( 5"C or lower) .

2) Avoid using the machine in dusty conditions.

PREPARATION FOR OPERATION

( 1)

Cleaning the machine

Before leaving the factory, the machine parts are coated with rust-preventive grease, which may be hardened and contaminated by dust during storage and shipment. This grease must be removed with gasoline.

( l)

Examination

Though every machine is confirmed by strict inspection and test before leaving the factory, the machine parts may be loose or deformed after long distance transportation with jolt. A thorough examination must be performed after cleaning the machine. Tum the pulley to see if there is running obstruction, parts collision, uneven resistance or abnormal noise.

If these exist, adjustment must be made accordingly before run-in operation.

(3)

Lubrication (Fig.l)

When a new sewing machin~ is used for the first time, or sewing machine left out of use for considerably long time is used again, replenish a· suitable amount of oil to the portions indicated by arrow in below figure.

CAUTION: Please use white spindle oil.

Always keep the presser lifted before attempting a dry run.

Fig.l

(4)

Testing

In order to get the best working situation, run the sewing machine in a low speed for about 1 month after lubricated fully. Then increase the speed to the need one.

CAUTION: Before using the foDowing procedures, be sure to turn the power switch off.

The needle used by this sewing machine is

DY X 3 26#o During operation, proper needle can be chosen according to the sewing thread. (the sewing thread should be able to pass the pinhole.)

5, WINDING OF BOBBIN THREAD (Fig.J)

(I)

Push the bobbin

® on the bobbin winder shaft as far as it will go.

(2) Bring the thread forward toward the bobbin and wind from below in clockwise direction several times around the bobbin.

(3) Push the lever

® toward other side so that the driving wheel and driven wheel will engage and then start the machine.

( 4)

The driven wheel will automatically be free from the driving wheel and stop after the bobbin is filled with thread.

6, ADJUSTMENT OF THE BOBBIN WINDER (Fig.J)

(1) In case of uneven winding

If the thread dose not wind evenly on the bobbin, loosen the nut

CD

and move the bracket

® to the right or to the left as may be required, then tighten the nut.

(2) Winding amount of thread

Adjusting

® can increase or decrease the amount of thread wound on the bobbin.

(3) Winding strength

Strength of the winding can be adjusted with the nut

CD.

7... THREADING (Fig.4)

Raise the needle bar to its highest position and route the upper thread in the order illustrated below.

Fig.4

8... REMOVING AND INSERTING THE BOBBIN

(1) Removing:

Open the shuttle race cap and the bobbin holder, then take out the bobbin.

(2)

Installation:

5

Put the bobbin in the rotary hook case, Permit about 5 em of bobbin thread to hand down freely. Install the bobbin in the bobbin case so that the thread wound direction is clockwise. Then close the rotary hook and the shuttle race cap.

9 ... ADJUSTING THE THREAD TENSION (Fig.5)

For ordi.naty stitching, the tension of the upper and the lower threads should be equal.

Well balanced stitch

Upper thread is too

str~

or lower thread is too weak

X

Upper thread is too weak or lower thread is too strong

Fig.5

(1) Tension of the Upper thread

Before adjusting the tension of the upper thread, be sure that presser foot is let down . To adjust tension, turn serrated nut on tension device to the right (c lockwise ) to increase tension and to the left (counter -clockwise) if you desire to decrease the tension .

(2) Tension of the lower thread

The lower thread tension is controlled by the larger scre"Yi near the end of the spring at the outside of the bobbin case. Turning this screw to the right (clockwise) will increase the thread tension, while turning it to the left (counter-clockwise) will decrease the tension.

10-. ADJUSTMENT OF PRESSER PRESSURE (Fig.6)

(1) Pressure should be adjusted according to the material to be sewn.

(2) Pressure on both the walking foot and the presser foot can be adjusted. (The adjusting screw has b een set before shipment.)

(3) Sewing pressure should be adjusted to the minimum required strength .

Fig.6

.~

.

(

11, ADJUSTMENT OF WALKING FOOT AND PRESSER FOOT (Fig.7)

(1) The alternating movement on the walking foot and presser foot can be adjusted by changing the position relations of the parts of the presser foot lifting mechanism.

(2) Changing the position relation of the connecting link

2 and the crank 3 can complete the adjustment.

(3)

Adjustment should be changed according to the thickness of the material to be sewn..

Fig.7

12, ADJUSTMENT OF STITCH LENGTH AND FORWARD/BACKWARD

SEWING (Fig.8)

(1) Adjusting the stitch length adjusting bolt can change the stitch length.

(2) Stitch length em be adjusted between 0-15mm.

(3) Setting the stitch length adjusting bolt above

"0" can backstitch.

Fig.8

13, FEED DOG HEIGHT (Fig.9)

The feed dog should be 1.5 mm higher than the vertex of the needle plate. Adjustment of the feed dog height can be done as follows:

(1) Thm the. machine pulley so as to raise the feed dog to its highest point.

(2) Loosen the screw of the feed dog and adjust the height by raising or lowering it. Then tighten the screw.

Fig.9

14, ADJUSTING THE HEIGHT OF THE NEEDLE BAR (Fig.lO)

When the needle bar iS at its highest point, normally the measurement between the highest point of the needle plate and the needlepoint is 28 mm. When this distance need to be adjusted, the steps is as follows:

(1) Take down the face plate, adjust the needle bar to its highest position.

(2) Loosen the screw of needle bar connecting stud screw.

(3) Adjust the needle bar to the right position.

(4) Tighten the screw.
