INSTRUCTION
MANUAL

Thank you very much for buying a BROTHER sewing machine. Before using your new machine,
please read the safety instructions 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, 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
Wai
t 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 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 f
or the sewing machine’s power
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.
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 approximately 57 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
foot switch is depressed by mistake, which could
result in injury.
Hold the machine head with both hands when tilting it
back or returning it to its original position.
Furthermore, after tilting 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.
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 safety
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.

3. INSTALLATION
3. 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 approximately 57
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
foot switch is depressed by mistake,
which could
result in injury.
Hold the machine head with both hands when tilting it
back or returning it to its original position.
Furthermore, after tilting 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.
All cords should be secured at least 25 mm away
from any moving parts. Furthermore, do not
excessively bend the cable or secure
it too firmly
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 the risk of receiving
a serious electric shock, and
problems with correct
operation may also occur.
Install the safety covers to the machine head and
motor.
3-1. Table processing diagram
• The thickness of the table should be at least 40 mm, and it should be strong enough to bear the weight and vibration of the
sewing machine.
• 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.
