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 voltages are present can result in severe injury.
DANGER
CAUTION
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 720 kg. The installation should be carried out by four or more people.
Do not connect the power cord until installa­tion is complete, otherwise the machine may operate if the start switch is pressed by mis­take, which could result in injury.
Be sure to connect the ground. If the ground connection is not secure, you run the risk of receiving a serious electric shock.
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 wear protective goggles and gloves when handling the lubricating oil or grease, so that no oil or grease gets into your eyes or onto your skin, otherwise inflammation can result. Furthermore, do not drink the oil or grease un­der any circumstances, as they can cause vom­iting and diarrhoea. Keep the oil out of the reach of children.
Avoid setting up the sewing machine near sources of strong electrical noise such as high­frequency welding equipment. If this precaution is not taken, incorrect machine operation may result.
The casters should be secured in such a way so that they cannot move.
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.
Turn off the power switch at the following times, otherwise the machine may operate if the start switch is pressed 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
Do not get on the table. Table may be damaged.
2
BES-961BC BES-1261BC
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.
Do not touch the pulse motor and sewing ma­chine bed section during operation or for 30 min­utes after operation. Otherwise burns may result.
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.
CAUTION
Cleaning
Turn off the power switch before starting any cleaning work, otherwise the machine may op­erate if the start switch is pressed by mistake, which could result in injury.
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 and knife.
Be sure to wear protective goggles and gloves when handling the lubricating oil or grease, so that no oil or grease gets into your eyes or onto your skin, otherwise inflammation can result. Furthermore, do not drink the oil or grease un­der any circumstances, as they can cause vom­iting and diarrhoea. Keep the oil out of the reach of children.
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.
Any problems in machine operation which re­sult from unauthorized modifications to the ma­chine will not be covered by the warranty.

3. Installation

Chapter 1 Preparation of Embroidery Machine
DANGER
Embroidery machines should be installed only by trained engineers.
Electric wiring should be laid by your distribu­tor or electric experts.
A machine weighs more than 720 kg. Installa­tion should be carried out by 4 or more work­ers.
Do not connect the power source until installa­tion is completed. Doing so may start the ma­chine unintentionally through an accidental activation of the START switch, resulting in bodily injuries.
Install a machine in a place away from a high­frequency welding machine or other machines that may generate a strong electric noise. Fail­ure to do so may cause the embroidery machine to malfunction.
Establish grounding as designated. Improper grounding may result in an electric shock.
* After installation is completed, get the power supply from a dedicated outlet. * When connecting multiple machines, exercise care not to exceed the capacity of the outlet.

3-1 Transportation of Machine

When relocating the machine, push the steel frame.
Note) Never push the cover or carriage.
When using a fork lift
Center pillar

Lift forks
Open the forks of the lift approximately 10 cm to the right from the even position to the center pillar viewed from the rear of the machine, and pass them under the legs to lift the machine.

1. Place the attached cushion sheets w and leveling plates e under the four level adjusters q. The leveling plates e should be placed above the cushion sheets respectively.
2. Secure the four level adjusters q on the ground using the nuts r so that the machine will be stable.
Note) If the floor is not strong enough, the embroi-
dery machine may be rocked during opera­tion. In such a case, it is recommended that a secure base of concrete be placed below the embroidery machine.
