Notes On Safety - Brother BM-917B Instruction Manual

2. Notes on safety

Do not put your hand into any openings near the belt, as your hands could get caught in the
belt, and serious injury could result.
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.
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
electrical consumption.
Insufficient power supply capacity 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.
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 more than 25 kg. The
installation should be carried out by two or more
people.
Do not connent the power cord until installation is
complete, otherwise the machine may operate if
the treadle is depressed by mistake, which could
result in injury.
Be sure to connnect 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.

Environmental requirements
Installation
BM-917B, 917C
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.
Avoid exposure to direct sunlight during use.
Exposure to direct sunlight 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
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, otherwise there is the danger that fire
or electric shocks could occur.
Install the pulley covers (sold separately) to the
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, so that no oil gets into
your eyes or onto your skin, otherwise inflammation
can result.
Furthermore, do not drink the oil under any circumstances,
as it can cause vomiting and diarrhoea.
Keep the oil out of the reach of children.
