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
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
Environmental requirements
Use the sewing machine in an area which is free
from sources of strong electrical noise such as
high-frequency 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 600 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 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.
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.
Secure the machine with the casters when installing it so that it will not move by placing the
leveling seat on the sound floor.
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.

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.
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.
Secure the machine with the casters when installing it so that it will not move by placing the
leveling seat on the sound floor.
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.
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.
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.
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.
BES-941BC • BES-1241BC
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 600 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.
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.
Secure the machine with the casters when installing it so that it will not move by placing the
leveling seat on the sound floor.
* 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.

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.
