Brother S-6200A Instruction Manual

S-6200A	INSTRUCTION MANUAL

Please read this manual before using the machine.

Please keep this manual within easy reach for quick reference.

SINGLE NEEDLE STRAIGHT LOCK STITCHER

WITH 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.

About the machine set-up location

Do not set up this sewing machine near other equipment such as televisions, radios or cordless telephones, otherwise such equipment may be affected by electronic interference from the sewing machine.

The sewing machine should be plugged directly into an AC wall outlet. Operation problems may result if extension cords are used.

2086M

Carrying the machine

The sewing machine should be carried by the arm and the machine pulley by two people as shown in the illustration.

*Do not hold by any part other than the machine pulley. If this is not observed, it may result in damage to the sewing machine.

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, so that it does not get into your eyes or onto your skin.

If care is not taken, inflammation can result. Furthermore, do not drink the lubricating oil. Diarrhea or vomiting may result.

Keep the oil out of the reach of children.

		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.
		Use only the lubricating oil (Nippon Oil Corporation
		Sewing Lube 10N; VG10) specified by Brother.
		* If this type of lubricating oil is difficult to obtain, the
		recommended oil to use is <Exxon Mobil Essotex SM10;
		VG10>.
		1. Tilt back the machine head.
		2. Slowly pour in lubricating oil until the oil level reaches the
		HIGH mark.
	3846M	* If the oil level drops below the LOW mark, add more
		lubricating oil.

DANGER

Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet before opening the cover of the control box. Touching areas where high voltages are present can result in severe injury.

CAUTION

Contact your Brother dealer or a qualified electrician for any electrical work that may need to be done.

Do not connect the power cord until all cords have been connected.

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

When securing the cords, do not bend the cords excessively or fasten them too hard with staples, otherwise there is the danger that fire or electric shocks could occur.

Be sure to connect the ground. If the ground connection is not secure, you run a high risk of receiving a serious electric shock, and problems with correct operation may also occur.

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

NOTE:

If the sewing machine does not operate even when the treadle (1) is depressed, check the position of the safety switch. (Refer to “13-1. Adjusting the safety switch position”.)

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.

2117M 5. With the machine head tilted back, depress the treadle (1) and check that the sewing machine does not operate.

NOTE:

If the sewing machine operates when the treadle (1) is depressed while the machine head is tilted back, the safety switch is probably faulty. Contact the place of purchase.

<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.
