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.
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 195 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 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 nuts 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.

Selecting needle
• When using special threads such as gold,
silver, and rame yarn, use a heavy-duty
needle (#11 ~ #16). For better finish, paste
the waxed paper on the back of the
material.
• In general, use DBxK5 #11 ~ #18 according
to the material thickness. For knitted
materials, use DBxK23 #11 because its
rounded point prevents the knit thread from
breaking.

Failure to do so may result in electric shock.
Use a cord plug that matches the receptacle type.
4-5 Preparation of Machine for Operation
Check the following before turning on the power
Thread (1) Is upper thread setting complete? (2) Is the thread passed smoothly?
(3) Is thread passed through needle? (4) Is the lower thread setting complete?
Embroidery hoop (1) Is there any looseness in the material? (2) Is the hoop clamped securely?
Needle stop position (1) Is thread take-up positioned correctly? (2) Is needle bar positioned at the top?
Check that the thread take-up lever is
aligned with the index mark.
Turning on the power switch brings up the
message "Moving frame" and sounds a
beep as a warning. Then, the X and Y
carriages move the embroidery hoop to the
home position or the position where it was
located at the end of the previous
operation. Check that there is no obstacle
above the hoop which will interfere with
