2. Notes on safety

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

DANGER

　　　　 CAUTION

Environmental requirements

Use the sewing machine in an area which is free from sources of strong electrical noise such as highfrequency welders. Sources of strong electrical noise may cause problems with correct operation.

Any fluctuations in the power supply voltage should be within ±10% of the rated voltage for the machine. Voltage fluctuations which are greater than this may cause problems with correct operation.

The power supply capacity should be greater than the requirements for the sewing machine’s electrical consumption. Insufficient power supply capacity may cause problems with correct operation.

Installation

Machine installation should only be carried out by a qualified technician.

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

The sewing machine weighs more than 56 kg. The installation should be carried out by two or more people.

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

Use both hands to hold the machine head when tilting it back or returning it to its original position. If only one hand is used, the weight of the machine head may cause your hand to slip, and your hand may get caught.

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.

The ambient temperature should be within the range of 5°C to 35°C during use. Temperatures which are lower or higher than this may cause problems with correct operation.

The relative humidity should be within the range of 45% to 85% during use, and no dew formation should occur in any devices. Excessively dry or humid environments and dew formation may cause problems with correct operation.

Avoid exposure to direct sunlight during use. Exposure to direct sunlight may cause problems with correct operation.

In the event of an electrical storm, turn off the power and disconnect the power cord from the wall outlet. Lightning may cause problems with correct operation.

All cords should be secured at least 25 mm away from any moving parts. Furthermore, do not excessively bend the cords or secure them too firmly with staples, otherwise there is the danger that fire or electric shocks could occur.

Install the belt covers to the machine head and motor.

If using a work table which has casters, the casters should be secured in such a way so that they cannot move.

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 diarrhoea. Keep the oil out of the reach of children.

Sewing

CAUTION

This sewing machine should only be used by operators who have received the necessary training in safe use beforehand.

The sewing machine should not be used for any applications other than sewing.

Be sure to wear protective goggles when using the machine. If goggles are not worn, there is the danger that if a needle breaks, parts of the broken needle may enter your eyes and injury may result.

Turn off the power switch at the following times, otherwise the machine may operate if the treadle is depressed by mistake, which could result in injury.

• When threading the needle

• When replacing the bobbin and needle

• When not using the machine and when leaving the machine unattended

Cleaning

Turn off the power switch before carrying out cleaning, otherwise the machine may operate if the treadle is depressed by mistake, which could result in injury.

If using a work table which has casters, the casters should be secured in such a way so that they cannot move.

Attach all safety devices before using the sewing machine. If the machine is used without these devices attached, injury may result.

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.

If an error occurs in machine operation, or if abnormal noises or smells are noticed, immediately turn off the power switch. Then contact your nearest Brother dealer or a qualified technician.

If the machine develops a problem, contact your nearest Brother dealer or a qualified technician.

Maintenance and inspection

Maintenance and inspection of the sewing machine should only be carried out by a qualified technician.

Ask your Brother dealer or a qualified electrician to carry out any maintenance and inspection of the electrical system.

Turn off the power switch and disconnect the power cord from the wall outlet at the following times, otherwise the machine may operate if the treadle is depressed by mistake, which could result in injury.

• When carrying out inspection, adjustment and maintenance

• When replacing consumable parts such as the rotary hook

Turn off the power switch before inserting or removing the plug, otherwise damage to the control box could result.

If the power switch needs to be left on when carrying out some adjustment, be extremely careful to observe all safety precautions.

Use only the proper replacement parts as specified by Brother.

If any safety devices have been removed, be absolutely sure to re-install them to their original positions and check that they operate correctly before using the machine.

• This is effective for preventing the material from getting stuck in the needle hole when sewing the rear tack, which can happen when using lightweight materials. (An offset is used so that the stitches do not overlap when sewing the reverse zigzagging for the rear tack.)

* Reducing the number of front tack stitches is effective in preventing the material getting stuck at the

front tack.

* Using a needle plate with a small needle hole (1.2) as well can also help in preventing the material

from getting stuck.

3. Saw-shape

1. Underlays sewn together

• This type of underlay pattern is used for resewing if the knife has operated before the seam has been formed, such as when sewing is complete without the upper thread breaking even though the lower thread has run out. It is particularly useful for sewing up the hole made by the knife beforehand at times when zigzag stitches do not hold properly.

• The pile of fluffy fabrics is pressed down before sewing, so that the buttonhole finish looks more attractive.

2. Saw-shape underlay

• This type of underlay is useful for stretch materials to prevent them from stretching.

• It is useful for preventing dimples from forming during bar tacking. Radial-type buttonholes are useful

for preventing dimples.

• It is also useful for strengthening the buttonholes to stop the seam from unravelling, which can often happen with materials with coarse weaves.

3. Rectangle underlay

• This type of underlay is useful for stretch materials to prevent them from stretching.

• This is effective in preventing seams from unravelling in materials which appear not to have a very

coarse weave. It also serves to reinforce the buttonhole.

• If the seam is hidden and the seam width seems small, you can sew 2 - 3 rectangle underlays to make the material look more voluminous.

• Underlays such as (1) to (9) in the illustration can be sewn in slightly different positions by changing the setting value for parameter No. 50 (underlay offset) so that the seam does not become too stiff and to further increase the feeling of volume.

4. Zigzag underlay stitch

• This is particularly effective in preventing seams from unravelling in materials which appear not to have a very coarse weave. It also serves to reinforce the buttonhole. (If parameter No. 58 - Zigzag width [Dimension A in the illustration] is set to about 0.4 mm, the zigzag underlay stitches will be even stronger than other underlay stitches.)

* If parameter No. 58 is set after saw-shaped underlay stitches or rectangle underlay stitches have been

set, zigzag underlay stitches will only be sewn for the first cycle of underlay stitching.)

NOTE:

When sewing underlays, the number of bar tacking stitches will increase, so that thread breakages or broken needles may occur. To avoid such problems, reduce the number of underlays or drop the sewing speed. * When underlays are sewn together, the order of sewing is underlays sewn together → saw-shape

underlays → rectangle underlays.

5. OPERATION

5-4-6. Cutter operation

The cutter operating pattern can be selected from the following four patterns.

• Center knife operation, where the cutter operates when sewing of the buttonhole is complete

• Rear knife operation, where the cutter operates when sewing of the buttonhole is complete and the

material is fed so that the cutter is near the front tack

• Front knife, where the cutter operates before the final cycle of zigzagging stitches is sewn

• A combination of front knife and center knife

2128Q

Because the needle and knife positions are separated by 2.2 mm as shown in the illustration, the distance between the edge of the front tack and the edge of the buttonhole cannot be set to less than 2.2 mm. In other words, if the knife Y space (A) is set to

0.5 mm, the front tack length (B) cannot be set to less than 1.7 mm. If you would like the front tack length to be less than 1.7 mm, the cutter can be made to operate after sewing and feeding are complete.

2.2 mm

Feeding

2: Front knife (Not available for single cycles. Only available when sewing two or more cycles.)

• This is used in cases such as when the rough edges of the material after cutting are hemmed by the buttonhole stitches. The cutter operates before the left zigzag stitch of the last cycle is sewn.

3: Front knife + Center knife

(Not available for single cycles. Only available when sewing two or more cycles.)

• This is used in cases such as when the rough edges of the material after cutting are hemmed by the buttonhole stitches. It can also be used if the rough edges of the material block the buttonhole after the left and right zigzag stitches have been sewn. The cutter operates before the left zigzag stitch of the last cycle is sewn, and then operates again after the right zigzag stitch is sewn.

2. Loosen the screw (9), and then adjust the clearance between the bend in the back plate (6) and the cam (7) to approximately 2 mm. If you would like the scissors to start opening earlier, make this clearance smaller.

3. Check that the upper thread scissors (3) open smoothly during feeding.

NOTE:

If the upper thread scissors (3) do not open smoothly, the upper thread scissors (3) may touch the cutter and needle breakage may occur.
