ENGLISH

Thank you very much for buying a BROTHER sewing machine. Before using your new machine, please read the safety instructions below 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 lever, 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.

[2] Notes on safety

DANGER

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

WARNING

Do not allow any liquids to get onto this sewing machine, otherwise fire, electric shocks or operating problems may occur.

If any liquid gets inside the sewing machine (machine head or control box), immediately turn off the power and disconnect the power plug from the electrical outlet, and then contact the place of purchase or a qualified technician.

CAUTION

Environmental requirements

Use the sewing machine in an area which is free from sources of strong electrical noise such as electrical line noise or static electric noise.

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 power consumption.

Insufficient power supply capacity may cause problems with correct operation.

The pneumatic delivery capability should be greater than the requirements for the sewing machine's total air consumption.

Insufficient pneumatic delivery capability may cause problems with correct operation.

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.

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.

Easy threading in threading mode

Page 24-25

When using threading mode for threading, the tension discs will open so that the thread can be threaded more easily.

Furthermore, threading mode is safe because the sewing machine will not start even when the start switch is depressed.

Presser foot height can be set easily using the

LCD panel or the control panel

Page 39-41

The height of the presser foot can be set simply by entering a numeric value at the LCD panel or the control panel, without the need for tools.

Adjusting the driver needle guard is simple and within close reach.

7-6. Adjusting the driver (needle guard) position

The driver needle guard (1) can be adjusted easily and within close reach without tilting back the machine head.

Work clamp lowering operation

4-8. Setting 2-step operation for the work clamp

You can select one of two different types of dropping operation for the work clamp (2) by changing memory switch settings.

<Work clamp dropping in one step>

When the work clamp switch is depressed, the work clamp (2) drops in one movement from its highest position A to its lowest position C.

<Work clamp dropping in two steps>

1.When the work clamp switch is depressed to the 1st step, the work clamp (2) drops from its highest position A to the intermediate position B.

2.When the work clamp switch is then depressed to the 2nd

step, the work clamp (2) drops to its lowest position C.

3-1. Table processing diagram

The thickness of the table should be at least 50 mm, and it should be strong enough to bear the weight and vibration of the sewing machine.

If using casters, use ones which can bear the total weight of sewing machine and table.

Check that the control box is at least 10 mm away from the leg. If the control box and the leg are too close together, it may result in incorrect sewing machine operation.

CAUTION

The control box is heavy, so installation should be carried out by two or more people.

In addition, take steps to make sure that the control box does not fall down.

If this is not done, injury to feet or damage to the control box may result.

2.After placing the machine head onto the table, remove the bolt (6) and the spacer (7).

*The bolt (6) and the spacer (7) are necessary for securing the support lever (8) when the machine head is removed from the table, so keep them in a safe place.

3.Pass the support lever shaft (9) through the hole in the support lever base (10) and through the groove (f) in the support lever (8), and push it in until it is flush with the surface of the support lever base (10).

*Be sure to insert so that the groove (g) in the support lever shaft (9) faces in the direction shown in the illustration.

*If it is difficult to pass the support lever shaft (9) through the groove (f) in the support lever (8), move the end of the support lever (8) up and down while passing the support lever shaft (9) through.

3-5. Tilting back and returning the machine head

CAUTION

Hold the machine head with both hands when tilting it back or returning it to its original position.

In addition, do not subject the machine head to extra force while it is tilted back. If this is not observed, the machine head may become unbalanced and fall down, and serious injury or damage to the sewing machine may result.

Always be sure to engage the stopper of the support lever (1) when tilting back the machine head.

If the stopper is not engaged, the machine head may return to its original position and your hands may get caught and injury may result.

When disengaging the stopper, hold it by the knob (a).

If you hold at the place indicated by (b), your hand will get caught between the support lever (1) and the table when the machine head is returned to its original position and injury will result.

Disengaging the stopper

Engaging the stopper

The machine head can be tilted back and returned to one of three heights.
