2. Notes on safety
A DANGER
lA
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.
A CAUTION
Environmental requirements
ft
Use the sewing machine in an area which is free from
V sources
of
strong electrical noise such as
high-frequency welders.
Sources
of
strong electrical noise may cause
problems with correct operation.
ft
Any fluctuations in the power supply voltage should
V be within ±10%
of
the rated voltage for the machine.
Voltage fluctuations which are greater than this may
cause problems with correct operation.
ft
The power supply capacity should be greater than the
V requirements for the sewing machine's electrical
consumption.
Insufficient power supply capacity may cause
problems with correct operation.
A The ambient temperature should be within the range
V
of
5°C to 35°C during use.
Temperatures which are lower
or
higher than this
may cause problems with correct operation.
A The relative humidity should be within the range of
V 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.
A Avoid exposure to direct sunlight during use.
V Exposure to direct sunlight may cause problems with
correct operation.
A In the event
of
an electrical storm, tum off the power
V and disconnect the power cord from the wall outlet.
Lightning may cause problems with correct operation.
Installation
I(:\
Machine installation should only be carried out by a
\..Y qualified technician.
0
Contact your Brother dealer
or
a qualified electrician
for any electrical work that may need to be done.
A The sewing machine weighs approximately 56 kg.
V The installation should be carried out by two
or
more
people.
f(;'\
Do not connect the power cord until installation is
\..Y complete, otherwise the machine may operate if the
foot switch is depressed by mistake, which could
result in injury.
A Hold the machine head with both hands when tilting it
~
back
or
returning
it
to its original 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
damage to the machine.
•
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.
0
All cords should be secured at least 25
mm
away
from any moving parts. Furthermore, do not
t<::"\
excessively bend the cords or secure them too firmly
\..Y with staples, otherwise there is the danger that fire or
electric shocks could occur.
A Install the safety covers to the machine head and
V motor.
A
If
using a work table which has casters, the casters
V should be secured in such a way so that they cannot
move.
t<::"\
Be sure to wear protective goggles and gloves when
\..Y handling the lubricating oil and grease, so that they
do not get into your eyes
or
onto your skin, otherwise
inflammation can result.
Furthermore, do not drink the oil or eat the grease
under any circumstances,
as
they can cause vomiting
and diarrhoea.
Keep the oil out
of
the reach
of
children.
