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.
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.
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 48 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.
