[2] Notes on safety
ii
A DANGER
/A Wait at least 5 minutes after turning off the power switch a nd disco nn ecting the power cord from th e wall outlet
~ before opening the cover of th e control box. Touching areas where high voltages are present can result in severe
injury.

Environmental requirements
0 Use t
he sewing machine in an area which is free from
sources
of strong electrical noise such as electrical
line noise
or staticelectric noise.
Sources
of strong electrical noise may cause
problems with correct operation.
0 Any fluctuations
in the power supply voltage should
bewithin ±10%
of the ra te d voltage for the machine.
Voltage fluctuations which are greater than this may
cause problems with correct operation.
0 The power supply capacity should
be greaterthan the
requirements for the sewing machine's power
consumption.
Insufficient power supply capacity may cause
prob
le mswith correct operation.
0 The pneumatic delivery capability should be greater
than the requirements for the sewing machine's total
air consumption.
Insufficient pneumatic delivery capability may cause
problems with correct operation.
0 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.
0 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 maycause problems with correctoperation.
0 In
th e event of an electrical sto rm , tu rn off the power
and disconnect the power cord from the wall outlet.
Lightning may cause problemswith correct operation.

• Be sure to connect the ground.
If the ground
connection is not secure, you
ru n a high risk of
receiving a serious electric shock, and problems with
correct operation may also occur.
0 All cords should be secured at least 25 mm away
from any moving parts. Furthermore, do not
excessively bend the cords

AcAUTION
Machine installation should only be carried out by a
qualified technician.
Contact your Brother dealer
or a qualified electrician
for anyelectrical workthat may need to be done.
The sewing machine head weighs approximately
88kg. The installation should be carried out by two or
morepeople.
Do not connect the power cord until installation is
complete.
If the foot switch is depressed by mistake, the sewing
machine might start operating and injury could resul

Hold the machine head with both hands when tilting it
backor returning itto its original position.
Furthermore,
do not apply excessive force when tilting
back the machine head. The sewing machine may
become unbalanced and fall down, and serious injury
or damageto the sewing machine mayresult.

All cords should be secured at least25 mm awayfrom
any moving parts. Furthermore, do not excessively
bend the cords or secure them too firmly staples,
otherwise 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 wi
th
correct operation mayalso occur.
Install the safety covers to the machine head and
motor.
3-1. Table processing diagram
• 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.
• Ifthe distance A between the insides
of the legs is less than 740 mm, move the co nt rol box installation positi on to the left (B =
261mm).
• Check that the control box is
at least 10mm away from the leg. If the control box and the leg are too close together, it may result
in incorrect sewing machineoperation.
