Thank you very much for buying a BROTHER sewing machine. Before using your new machine, please read the safety instructions
below and the explanations given in the instruction manual.
With industrial sewing machines, it is normal to carry out work while positioned directly in front of moving parts such as the needle
and thread take-up lever, and consequently there is always a danger of injury that can be caused by these parts. Follow the
instructions from training personnel and instructors regarding safe and correct operation before operating the machine so that you
will know how to use it correctly.
Safety indications and their meanings
This instruction manual and the indications and symbols that are used on the machine itself are provided in order to
ensure safe operation of this machine and to prevent accidents and injury to yourself or other people. The meanings of
these indications and symbols are given below.

Notes on safety
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 prob-
lems with correct operation.
Any fluctuations in the power supply voltage should
be within ±10% of the rated voltage for the ma-
chine.
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 electri-
cal consumption.
Insufficient power supply capacity may cause prob-
lems 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.
