Notes on safety

2.
Wait at least 10 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.
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
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 to 35
Temperatures which are lower or higher than this
may cause problems with correct operation.
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 36 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.
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.
DANGER
CAUTION
Environmental requirements
10% of the rated voltage for
during use.
Installation
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.
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, so that no oil
gets into your eyes or onto your skin, otherwise
inflammation can result.
Furthermore, do not drink the oil under any
circumstances, as they can cause vomiting and
diarrhea.
Keep the oil out of the reach of children.
Use a lamp which is rated at 6 V AC and 20 W or
less. If a lamp with a higher rating than this is
used, it could cause the lamp wires and the
transformer to overheat and burn out, which could
result in fire.
