For the sewing machine, automatic machine and ancillary devices (hereinafter collectively referred to as
"machine"), it is inevitable to conduct sewing work near moving parts of the machine. This means that there
is always a possibility of unintentionally coming in contact with the moving parts. Operators who actually
operate the machine and maintenance personnel who are involved in maintenance and repair of the machine
are strongly recommended to carefully read to fully understand the following
SAFETY PRECAUTIONS
before using/maintaining the machine. The content of the
SAFETY PRECAUTIONS
includes items which
are not contained in the speci
¿
cations of your product.
The risk indications are classi
¿
ed into the following three different categories to help understand the meaning
of the labels. Be sure to fully understand the following description and strictly observe the instructions.
