PROGRAMMABLE ELECTRONIC PATTERN 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 it correctly.

[2] Notes on safety
DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet
before opening the cover 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 for 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.
The pneumatic delivery capability should be greater
than the requirements for the sewing machine's total
air consumption.
Insufficient pneumatic delivery capability 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 88 kg.
The installation should be carried out by two or more
people.
Do not connect the power cord until installation is
complete. If the foot switch is depressed by mistake,
the sewing machine might start operating and injury
could result.
Hold the machine head with both hands when tilting it
back or returning it to its original position.
Furthermore, do not apply excessive force when
tilting back the machine head. The sewing machine
may become unbalanced and fall down, and serious
injury or damage to the sewing machine may result.
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.
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. If the oil
and grease get into your eyes or onto your skin,
inflammation can result.
Furthermore, do not drink or eat the lubricating oil or
grease. They may cause diarrhea or vomiting.
Keep the oil out of the reach of children.
BAS-311G, BAS-326G
CAUTION
Sewing
This sewing machine should only be used by
operators who have received the necessary training
in safe use beforehand.
If using a work table which has casters, the casters
should be secured in such a way so that they cannot

CAUTION
Do not connect the power cord until lubrication is complete.
If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result.
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. If the oil and grease get into your eyes or onto your skin, inflammation can result.
Furthermore, do not drink or eat the lubricating oil or grease. They may cause diarrhea or vomiting.
Keep the oil out of the reach of children.
The sewing machine should always be lubricated and the oil supply replenished before it is used for the first time, and also after
long periods of non-use.
Use only the lubricating oil <Nippon Oil Corporation Sewing Lube 10N; VG10> specified by Brother.
* If this type of lubricating oil is difficult to obtain, the recommended oil to use is <Exxon Mobil Essotex SM10; VG10>.

(CF cards with a capacity of more than 2GB are not supported.)
• Do not disassemble or modify the CF card.
• Do not bend, drop or scratch CF cards or place heavy objects on top of them.
• Avoid contact with liquids such as water, oil, solvents or drinks.
• Use and store CF cards in locations that are free from strong static electricity and electrical interference.
• Do not use or store CF cards in places where they may be subject to vibrations or shocks, direct sunlight, high
temperature or humidity or strong magnetic fields from equipment such as speakers, or places which are dusty from thread
scraps, etc.
• Do not subject CF cards to shocks or impacts or remove them from the sewing machine while data is being loaded or
written.
• The data on the CF cards may become lost or corrupted due to some malfunction or accident. It is recommended that you
make a backup of important data.
• CF cards should only be removed after the power for the sewing machine has been turned off.
• CF cards are already formatted when they are purchased, and so you should not reformat them.
• The recommended CF cards are commercially-available ones from SanDisk or HAGIWARA SYS-COM. CF cards from
other manufacturers can be used, but different formatting methods may mean that loading from or writing to such cards
may not be possible.
For more information, refer to the documentation provided with the CF card.
