[2] Notes on safety
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.
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 49 kg
(108lb). The installation should be carried out by
two or more people.
Do not connect the power cord until installation is
complete. The machine may operate if the treadle
is depressed by mistake, which may result in injury.
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.
CAUTION
Environmental requirements
Installation
DA-927A, DA-928A
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
operation.
In the event of an electrical storm, turn off the power
and disconnect the power cord from the wall outlet.
Lightning may cause
operation.
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.
If this is not observed, fire or electric shocks may
result.
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, so that it does not get
into your eyes or onto your skin. If care is not taken,
inflammation can result.
Furthermore, do not drink the lubricating oil.
Diarrhea or vomiting may result.
