2. Notes on safety
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 pro-
blems 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 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 opera-
tion.
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 56 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
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 connect the ground. If the ground connec-
tion 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 belt 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.
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 voltage are present can result in
severe injury.

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,
otherwise the machine may operate if the treadle is
depressed by mistake, which could result in injury.
• When threading the needle
• When replacing the bobbin and needle
• 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.
If an error occurs in machine operation, or if ab-
normal 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, otherwise the machine may operate if the
treadle is depressed by mistake, which could result
in injury.
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.
Maintenance and inspection
Maintenance and inspection of the sewing machine
should only be carried out by a qualified technician.
Ask your Brother dealer or a qualified electrician to
carry out any maintenance and inspection of the
electrical system.
Turn off the power switch and disconnect the power
cord from the wall outlet at the following times,
otherwise the machine may operate if the treadle is
depressed by mistake, which could result in injury.
• When carrying out inspection, adjustment and
maintenance
• When replacing consumable parts such as the
rotary hook
Turn off the power switch before inserting or
removing the plug, otherwise damage to the control
box could result.
If the power switch needs to be left on when carrying
out some adjustment, be extremely careful to
observe all safety precautions.
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.
Use only the proper replacement parts as specified
by Brother.
If any safety devices have been removed, be
absolutely sure to re-install them to their original
positions and check that they operate correctly
before using the machine.

Use the power table which has been specially designed for each sewing machines.
Positioning Model code
Vertical 127-H80-200-01
Table/legs assembly
Horizontal 127-H80-201-01
If using a commercially-available table, process it as shown in the following illustration.
NOTE:
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.
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 more
than 56 kg. The installation should be car-
ried out by two or more people.
Do not connect the power cord until in-
stallation is complete, otherwise the ma-
chine may operate if the treadle is de-
pressed 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.
All cords should be secured at least 25 mm
away from any moving parts. Further-
more, do not excessively bend the cords o
r
secure them too firmly with staples, other-
wise 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 a
high risk of receiving a serious electric
shock, and problems with correct opera-
tion may also occur.
Install the belt covers to the machine head
and motor.
