x 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.
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.
Any fluctuations in the power supply volt-
age should be within ±10% of the rated
voltage for the machine.
Voltage fluctuations which are greater than
this may cause problems with correct op-
eration.
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.
The power supply capacity should be
greater than the requirements for the sew-
ing machine’s electrical consumption.
Insufficient power supply capacity may
cause problems with correct 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.
The pneumatic delivery capability should be
greater than the requirements for the sew-
ing machine’s total air consumption.

CAUTION
Maintenance and inspection of the sewing
machine should only be carried out by a quali-
fied technician.
Hold the machine head with both hands
when tilting it back or returning it to its origi-
nal position. Furthermore, after tilting back
the machine head, do not push the face plate
side or the pulley side from above, as this
could cause the machine head to topple over,
which may result in personal injury or dam-
age to the machine.
Ask your Brother dealer or a qualified electri-
cian to carry out any maintenance and inspec-
tion of the electrical system.
Turn off the power switch and disconnect the
power cord from the wall outlet at the follow-
ing times, otherwise the machine may oper-
ate if the foot switch is depressed by mistake,
which could result in injury.
¡ When carrying out inspection, adjustment
and maintenance
If the power switch needs to be left on when
carrying out some adjustment, be extremely
careful to observe all safety precautions.
If any safety devices have been removed, be
absolutely sure to re-install them to their
original positions and check that they oper-
ate correctly before using the machine.
¡ When replacing consumable parts such as
the rotary hook and knife
Note:
¡ Turn the power switch off if the adjustment does not need power to be supplied.
¡ If the power switch is turned on, take sufficient safety measures, such as to make E-800 (emergency stop) come
on in the manual mode.
