,automatic machine and ancillarydevices (hereinafter collectively referred

to

as

"machine"), it is inevitable

to

conduct sewing work

near

moving parts

of

themachine 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

re

air

of

the

machine are strongly recommended

to

carefully read

to

fully understand the following Safety

precautions

before using/matntaimng the machine. The content

of

the I

Safety
