Please read this manual before using the machine.
Please keep this manual within easy reach for quick reference.
ELECTRONIC LOCKSTITCH BUTTON HOLER
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 face plate of the control box. Touching areas where high voltage are present can result in severe injury.
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.
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.
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.
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.

CAUTION
Sewing
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
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.
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.
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.
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 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.
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.
Any problems in machine operation which result from unauthorized modifications to the machine will not be covered by the warranty.

3. OPTIONAL PARTS
This needle plate uses the elasticity of rubber to prevent the cutter from getting stuck and not returning. It also helps to keep the cutter blade sharp.

4. INSTALLATION
CAUTION
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 head 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.
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.
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.
Install the belt covers to the machine head and motor.
Use the power table which has been specially designed for each sewing machines.
