INSTRUCTION MANUAL

 

Please read this manual before using the machine.

Please keep this manual within easy reach for quick reference.

SINGLE NEEDLE DIRECT DRIVE LOCK STITCHER WITH ELECTRONIC FEEDING SYSTEM AND THREAD TRIMMER

Thank you very much for buying a BROTHER sewing machine. Before using your new machine, please read the safety instructions and the explanations given in the instruction manual.

With industrial sewing machines, it is normal to carry out work while positioned directly in front of moving parts such as the needle and thread take-up, and consequently there is always a danger of injury that can be caused by these parts. Follow the instructions from training personnel and instructors regarding safe and correct operation before operating the machine so that you will know how to use it correctly.

3-3. Lubrication

CAUTION

Do not connect the power cord until lubrication has been completed, otherwise the machine may operate if the treadle is depressed by mistake, which could result in injury.

Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get into your eyes or onto your skin, otherwise inflammation can result.

Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and diarrhea.

Keep the oil out of the reach of children.

When cutting the nozzle of the oil tank, hold the base of the nozzle securely. If you hold the end of the nozzle, injury from the scissors may result.

The sewing machine should always be lubricated and the oil supply replenished before it is used for the first time, and also after long periods of non-use.

1. Hold the base of the nozzle of the accessory oil tank (1), and use scissors to cut about half-way along the straight section (A) of the nozzle.

2. Loosen and remove the nozzle, and then remove the seal

(2).

3. Tighten the nozzle.

4. Open the oil feeding pocket cover (3).

5. Insert the nozzle of the oil tank (1) deeply into the oil feeding pocket (4), and then add about 120 ml of lubricating oil.

6. Check that the oil gauge (6) comes to the upper reference line in the oil gauge window (5).

7. Close the oil feeding pocket cover (3).

<Lubrication oil replenishment interval>

Be sure to add more oil if the oil gauge (6) is below the lower reference line.

CAUTION

Do not touch any of the moving parts or press any objects against the machine while sewing, as this may result in personal injury or damage to the machine.

1. Turning on the power

Press the ON power switch (1).

The power indicator (2) will illuminate.

2. Test operation

1. Check that the machine sews at low speed when the treadle (1) is gently pressed to position (B).

2.Then check that it sews at high speed when the treadle

(1)is gently pressed to position (C).

3. After

pressing the treadle (1) forward, check

that

the needle is lowered to the top of the needle plate

when the treadle (1) is returned to the neutral position

(A). (when needle down stopping has been set.)

4.If the treadle (1) is pressed to position (D), thread trimming is carried out and the needle then rises above the needle plate and stops.

3-6. Adjusting the treadle

0939D

<Forward depression sensitivity adjustment>

If the machine starts running at low speed when your foot is simply resting on the treadle, or if the treadle pressure is felt to be too weak, adjust the position (a to c) at which the treadle spring (1) is hooked onto the treadle lever (2).

*a is the weakest position, and it becomes gradually stronger at b, c and d respectively.

<Backward depression sensitivity adjustment>

1.Loosen the nut (3) and turn the bolt (4).

*When the bolt (4) is tightened, the treadle operation becomes heavier, and when it is loosened, the operation becomes lighter.

2.Tighten the nut (3).

<Adjusting the treadle stroke >

Remove the nut (5), and then move the connecting rod joint

(6) from the position in figure A to the position in figure B. The treadle stroke will then be increased by approximately 27 %.

At this time, the treadle forward and backward depression sensitivity will change, so readjust if necessary.

4-1. Installing the needle

CAUTION

Turn off the power switch before installing the needle.

The machine may operate if the treadle is depressed by mistake, which could result in injury.

 

1.

Turn the machine pulley to move the needle bar to its

 

 

highest position.

2.

Loosen the screw (1).

3.

Insert the needle (2) in a straight line as far as it will go,

 

 

making sure that the long groove on the needle is at the

Front

left, and then securely tighten the screw (1).

CAUTION

Turn off the power switch before removing the bobbin case.

The machine may operate if the treadle is depressed by mistake, which could result in injury.

1.

Turn the machine pulley to raise the needle until it is above

 

 

the needle plate.

2.

Pull the latch (1) of the bobbin case upward and then

 

 

remove the bobbin case.

3.

The bobbin (2) will come out when the latch (1) is

 

 

released.

 

* There is an anti-spin spring (3) inside the bobbin case. The

 

 

anti-spin spring (3) prevents the bobbin from racing at

 

 

times such as during thread trimming.

 

* Use bobbins (2) made of light alloy as specified by

 

 

BROTHER.

More thread

1.Turn on the power switch.

2.Place the bobbin (1) onto the bobbin winder shaft (2).

3.Wind the thread several times around the bobbin (1) in the direction indicated by the arrow.

4.Push the bobbin presser arm (3) toward the bobbin(1).

5.Raise the presser foot with the lifting lever.

6.Depress the treadle. Lower thread winding will then start.

7.Once winding of the lower thread is completed, the bobbin presser arm (3) will return automatically.

8.After the thread has been wound on, remove the bobbin and cut the thread with the knife (4).

*Loosen the screw (5) and move the bobbin presser (6) to adjust the amount of thread wound onto the bobbin.

NOTE:

The amount of thread wound onto the bobbin should be a maximum of 80 % of the bobbin capacity.

3.

Pass the thread through the slot (1) and under the tension

 

 

 

spring (2), and then pull it out from the thread guide (3).

 

 

4.

Check that the bobbin turns clockwise when the thread is

 

 

 

pulled.

CAUTION

Turn off the power switch before threading the upper thread.

The machine may operate if the treadle is depressed by mistake, which could result in injury.

Turn the machine pulley and raise the thread take-up (1) before threading the upper thread. This will make threading easier and it will prevent the thread from coming out at the sewing start.
