[2] 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 control box cover. Touching areas where high voltages are present can result in severe injury.
WARNING
Do not allow any liquids to get onto this sewing machine, otherwise fire, electric shocks or operating problems may
occur.
If any liquid gets inside the sewing machine (machine head or control box), immediately turn off the power and
disconnect the power plug from the electrical outlet, and then contact the place of purchase or a qualified
technician.
CAUTION
Environmental requirements
Use the sewing machine in an area which is free from
sources of strong electrical noise such as electrical
line noise or static electric noise.
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 power
consumption.
Insufficient power supply capacity may cause
problems with correct operation.
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.
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 formation should
occur in any devices.
Excessively dry or humid environments and dew
formation may cause problems 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.
Installation
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 approximately 88 kg.
The
installation should be carried out by two or more
people.
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 result.
Hold the machine head with both hands when tilting it
back or returning it to 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 damage to the sewing machine may 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.
All cords should be secured at least 25 mm away
from
any moving parts. Furthermore, do not
excessively bend the cords or secure them too firmly
with staples,
otherwise there is the danger that fire or
electric shocks could occur.
Install the safety
covers to the machine head and
motor.
If using a work table which has casters, the casters
should be secured in such a way so that they cannot
move.
Be sure to wear protective goggles and gloves when
handling the lubricating oil and grease, so that they
do not get into your eyes or onto your skin. If the oil
and grease get into your eyes or onto your skin,
inflammation can result.
Furthermore, do not drink or eat the lubricating oil or
grease. They may cause diarrhea or vomiting.
Keep the oil out of the reach of children.
