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 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 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.
Machine installation should only be carried out
by a qualified technician.
Contact your Brother dealer or a qualified elec-
trician for any electrical work that may need to
be done.
The sewing machine weighs more than 600 kg.
The installation should be carried out by four
or more people.
Do not connect the power cord until installa-
tion is complete, otherwise the machine may
operate if the start switch is pressed by mis-
take, 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
Installation
BES-941BC • BES-1241BC
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 forma-
tion should occur in any devices.
Excessively dry or humid environments and
dew formation may cause problems with cor-
rect operation.
Avoid exposure to direct sunlight during use.
Exposure to direct sunlight may cause prob-
lems 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.
Be sure to wear protective goggles and gloves
when handling the lubricating oil or grease, so
that no oil or grease gets into your eyes or onto
your skin, otherwise inflammation can result.
Furthermore, do not drink the oil or grease un-
der any circumstances, as they can cause vom-
iting and diarrhoea.
Keep the oil out of the reach of children.
Avoid setting up the sewing machine near
sources of strong electrical noise such as high-
frequency welding equipment.
If this precaution is not taken, incorrect machine
operation may result.
Secure the machine with the casters when in-
stalling it so that it will not move by placing the
leveling seat on the sound floor.
