							S-7200A i
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, 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.

							S-7200A ii 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 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 
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 machines 
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. 
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 50 kg. The 
installation should be carried out by two or more 
people. 
Do not connent the power cord until installation is 
complete. The machine may operate if the treadle 
is depressed by mistake, which could result in 
injury. 
Turn off the power switch before inserting or 
removing the plug, otherwise damage to the 
control box could 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. 
 
 
 
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. 
If using a work table which has casters, the casters 
should be secured in such a way so that they 
cannot move. 
Use both hands to hold the machine head when 
tilting it back or returning it to its original position. If 
only one hand is used, the weight of the machine 
head may cause your hand to slip, and your hand 
may get caught. 
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 diarrhea. 
Keep the oil out of the reach of children.

 CAUTION 
Sewing 
 
 
 
 
 
 
 
 
 
 
 
 
This sewing machine should only be used by 
operators who have received the necessary training 
in safe use beforehand. 
The sewing machine should not be used for any 
applications other than sewing. 
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. 
Turn off the power switch at the following times. 
The machine may operate if the treadle is 
depressed by mistake, which could result in injury. 
y When threading the needle 
y When replacing the bobbin and needle 
y When not using the machine and when leaving 
the machine unattended 
If using a work table which has casters, the casters 
should be secured in such a way so that they 
cannot move. 
 
 
 
 
 
 
 
 
Attach all safety devices before using the sewing 
machine. If the machine is used without these 
devices attached, injury may result. 
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. 
Use both hands to hold the machine head when 
tilting it back or returning it to its original position. If 
only one hand is used, the weight of the machine 
head may cause your hand to slip, and your hand 
may get caught. 
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. 
Cleaning 
 
 
Turn off the power switch before carrying out 
cleaning. The machine may operate if the treadle is 
depressed by mistake, which could result in injury. 
Use both hands to hold the machine head when 
tilting it back or returning it to its original position. If 
only one hand is used, the weight of the machine 
head may cause your hand to slip, and your hand 
may get caught. 
 
 
 
 
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 diarrhea. 
Keep the oil out of the reach of children. 
Use only the proper replacement parts as specified 
by Brother.
