AUTOMATIC LOCKSTITCH BUTTON SEWER
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 the machine correctly.

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 voltages 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.
The air supply should have a capacity greater than the
machine air consumption. If air is not supplied
sufficiently, a machine malfunction may occur.
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 260 kg. The
installation should be carried out by two or more people.
Install the belt covers to the machine head and motor.
Do not connect the power cord until installation is
complete, otherwise the machine may operate if the
foot switch is pressed 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.
Hold the machine head with both hands when tilting it
back or returning it to its original position.
Furthmore, after tilring back the machine head, do not
push the face plate side or the pulley side from above,
as this could cause the machine head to topple over,
which may result in personal injury or damage to the
machine.
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.
ii
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.
BAS-556
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

machine. If the machine is used without these devices
attached, injury may result.
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.
Set the needle to the needle up stop position before
turning on the power.
If this is not done, the wiper may strike the needle,
which might cause the needle to break.
Turn off the power switch at the following times,
otherwise the machine may operate if the foot switch
is pressed by mistake, which could result in injury.
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, 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.

*1 Check that the button hole diameter is 2 mm or greater before using the programs.
*2 Be sure to remove the release bar.
*3 The presser foot lifts up once and the wiper operates, and then the other side is sewn, because there is no
crossover thread to be sewn. (Operation will be different if the optional solenoid-type thread wiper is installed.
[Refer to page 5].)
• If you want to sew a pattern other than one of the standard 24 patterns, you can create your original pattern
usingthe BAS-PC/300.
Consult with your local Brother Sales Office for details.
• If using the release bar, it may cause the number of stitches sewn to be reduced, which may cause the appearance
to suffer. In such cases, try using a program which has a greater number of stitches.
