CAUTIONS FOR SAFETY
TO ENSURE SAFE USE OF YOUR SEWING MACHINE
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 specifications of your product.
The risk indications are classified 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.

Precautions to be taken so as to use the MB-1800 Series more safely
1. To avoid electrical shock, neither open the cover of the electrical components and
the cover of the side face nor touch the electrical components inside the cover.
1. Do not place your hands and fingers under the button clamp to prevent injury since
the button clamp comes down when you turn the power OFF.
2. To avoid personal injury, never operate the machine with any of the cover of the
electrical components, pulley cover, finger guard, eye protection cover, needle bar
cover, or safety devices removed.
3. To avoid personal injury, never put your hand under the needle when you turn ON the
power switch or operate the machine.
4. To avoid personal injury, be careful not to allow your fingers to be caught in the
machine when tilting/raising the machine head.
5. To avoid accidents caused by abrupt start of the machine, turn OFF the power to
the machine when tilting the machine head, or removing the cover of the electrical
components or the cover of the side face.
6. The motor does not sound when the machine stops.
To avoid accidents caused by abrupt start of the machine, be careful not to forget to
turn OFF the power to the machine.
7. To avoid electrical shock hazards, never operate the sewing machine with the ground
wire for the power supply removed.
8. To prevent accidents caused by electrical shock hazrads or damaged electrical
component(s), be sure to turn OFF the power switch in prior to the connection/
disconnection of the power plug.
9. Be sure to clean the fan filter located at the bottom face of the cover of the electrical
components once a week.
10. Be careful of handling this product so as not to pour water or oil, shock by dropping,
and the like since this product is a precision instrument.
11. If this machine is used in the household environment, it can cause radio frequency
interference. In this case, the user may be required to take an appropriate preventive
measure against the radio frequency interference.

Safety devices and warning labels
Warning label against
pinching
Needle bar cover
This is a cover for
preventing contact
between the human
body and the needle
bar.
The purpose of this
label is to warn the
operator to be careful
to prevent pinching
of the human body in
the presser foot and
related parts.
Warning label
The label gives
the minimum
precautions to
be taken when
operating the
sewing machine.
(Refer
to the
warning label on
page
i.)
Eye protection cover
This is the cover
for protecting eyes
from being damaged
by a broken needle
or fragments of a
broken button.
Control box cover
This is a cover for
preventing contact
between the control
box components
and the human body.
Hand pulley cover
Looper cover
This is a cover for
preventing contact between the human body
and the looper section.
Finger guard
This is a cover for
preventing contact
between fingers and
the needle.
This is a cover for
preventing entanglement of hands, hair
and clothes by the
hand pulley.
Power switch
This is a switch for disconnecting the power unit of
the sewing machine from
the power supply.
Power switch (EU type)
This switch is
used for disconnecting the power
unit of the sewing
machine from the
power supply. It
is also used as
the emergency
stop switch.
Side cover
This is a cover for
preventing contact
between the electrical
parts and the human
body.
Selection of the power switch
Hazardous voltage warning seal
This is the warning seal purpose
of which is to prevent against
electrical shock.
CAUTION
Use the IEC60204-1-compliant
power switch with rated
current of 20 A or more and
short-circuit breaking capacity of 120 A or more, which
has the operating section in
red against the yellow background.
In addition, be aware that the safety devices such as the "eye protection cover" and
"finger guard" are sometimes omitted in the sketches, illustrations and figures included
in the Instruction Manual for the explanation's sake. In the practical use, never remove
those safety devices.
