INSTRUCTION MANUAL
Please read this manual before using the machine.
Please keep this manual within easy reach for quick reference.
AUTOMATIC LOCKSTITCH POCKET WELT SEWER
Thank you very much for buying a BROTHER sewing machine. Before using your new machine,
please read the safety instructions below and explanations given in the instruction manual.
The nature of industrial sewing machine requires operators to be always exposed to the hazard
to themselves, because they have to work very close to moving parts such as the needle and
thread take-up lever. Prior to using, be sure to be well informed of instructions for safe and
correct operation of the machine by experts and/or instructors.
SAFETY INSTRUCTIONS

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
presant can result in severe injury.
DANGER
CAUTION
Requirements for environment
Use the machine in an area free of the impact
from sources of strong electrical noise such
as high-frequency welders. Sources of strong
electrical noise may cause problems with
correct operation of the machine.
Any fluctuations in the power supply voltage
should be within ±10% of the rated voltage
for the machine. Voltage fluctuations greater
than this range may cause problems with
correct operation of the machine.
The power supply capacity should be greater
than the requirements for electrical consumption of the machine. Insufficient power supply capacity may cause problems with correct operation of the machine.
The air supply capacity should be greater
than the requirements for air consumption of
the machine. Insufficient air supply may
cause problems with correct operation of the
machine.
The ambient temperature during use should
be within the range from 5°C to 35°C Temperature lower or higher than this range may cause
problems with correct operation of the machine.
The relative humidity in operation should be
within the range from 45% to 85% and no dew
formation should occur in any device. Excessive
dry or humid environment and dew formation may
cause problems with correct operation of the machine.
Avoid exposure to direct sunlight in operation.
Exposure to direct sunlight may cause problems with correct operation of the machine.
When an electrical storm occurs, turn off the
power and plug off the power cord. Lightening may cause problems with correct operation of the machine.
Do not use the machine outdoors.
Installation
Machine installation should be carried out
only by a qualified technician.
Contact your Brother dealer or a qualified
electrician for any electrical wiring.
The machine weighs 225kg. The installation
should be carried out by two persons or more.
Do not plug in the power cord before the installation is completed. Unintended press on
the foot switch may cause injury.
Be sure to connect ground. Insecure grounding may cause problems with correct operation and a serious electrical shock.

BAS-6150
Be sure to wear protective goggles and gloves
when handling lubricating oil or grease so that
no oil or grease gets into your eyes or onto your
skin. Do not eat or drink lubrication oil or grease
in order not to have vomiting or diarrhea. Keep
oil and grease out of the reach of children.
Install the machine well apart from sources
of strong electrical noise such as high-frequency welding equipment. Otherwise, incorrect machine operation may result.
Place the leveling sheet on the sound floor
and secure the machine with casters so that
it will not move.
CAUTION
Sewing
The machine should be operated only by
operators who have been trained for safety
operation.
Do not let children access to the machine.
The machine should not be used for any other
application than sewing.
Be sure to wear protective goggles when
operating the machine. Otherwise, a broken
needle may get in your eyes and cause injury.
Turn off the power on the following occasions. Otherwise, unintended press on the
foot switch may cause injury.
• When replacing a needle
• When not operating the machine and leaving it unattended
Do not operate the machine where an aerosol
product (air spray) is used or where oxygen is
being administered.
Attach all safety devices before using the
machine. Operation without safety device
may cause injury.
Do not touch any of the moving parts nor press
any objects against the machine in operation.
Any touch or press may cause damage to the
machine or injury to human body.
Do not put objects or a screwdriver in the
exhaustion outlet or inside the machine. Accidental touch on an area with high voltage
may cause electrical shock.
Do not damage, process, heat, and apply excessive force to the power cord or other wiring cords. Breakage of the power cord and
other wiring cords may cause fire or electric
shock.
Turn off the power switch when the control
unit is subject to water or chemicals. Continuous operation of the control unit subjected to water or chemicals may cause fire
or electrical shock.
Turn off the power switch when incorrect
operation and abnormal sound or smell are
noticed. Contact your Brother dealer or a
qualified technician.
Contact your Brother dealer or a qualified
technician when the machine is in trouble.

Cleaning
Turn off the power switch before cleaning.
Unintended press on the foot switch may
cause injury.
Disconnect the air hoses from the air supply
and wait for the needle on the pressure gauge
to drop to "0" before carrying out inspection,
adjustment and repair of any parts which use
the pneumatic equipment.
Maintenance and inspection
Be sure to turn off the power switch when the
machine is raised. Unintended press on the
foot switch may cause injury.
Turn off the power switch and pull off the plug
by holding not of the cord but of the plug for
the following occasions. Otherwise, unintended press on the foot switch may cause
injury.
• maintenance, adjustment, and repairment
• replacement of consumable parts such as
the rotary hook, knife, lamp, etc
When adjustment has to be done with the
power switch and air supply on, pay enough
attention to safety. Detach the air tube of air
source and set the pointer of the pressure
gauge to [0] for inspection, adjustment, and
repair of air using devices.
Be sure to wear protective goggles and
gloves when handling lubricating oil or
grease so that no oil or grease gets into your
eyes or onto your skin. Do not eat or drink
lubrication oil or grease in order not to have
vomiting or diarrhea. Keep oil and grease out
of the reach of children.
If safety devices are once detached, re-attach
them to the original position. Make a check to
confirm that they are in proper function.
Loss and others due to remodeling the machine are excluded from the scope of warranty.
Do not put scissors, needles, threads, tools
on the table when the machine is set upright.
Falling down of them may cause damage to
the machine or injury to human body.
Ask your Brother dealer or a qualified technician for electrical maintenance and inspection.
