Warning
2.3) Machine Installation
Caution
Depending on the installation environment, function errors, breakdown, or other physical
damage might result. Make sure to meet the following conditions for machine installation:
1) The workbench or table where the machine is installed should be durable enough to endure
the weight of the machine (see the name plate).
2) Dust and humidity are the cause of machine pollution and erosion. Please install an air
conditioner and conduct regular maintenance of the machine.
3) Install the machine at the place where it is not exposed to direct sunlight (if the machine is
exposed to direct sunlight for a long time, it may cause discoloration or deformation).
4) Secure the space around the machine. Place the machine at least 50cm away from the left,
right, and rear walls to secure sufficient space for maintenance activities.
5) Explosion risk : To prevent possible explosion, immediately stop the machine operation if
there are inflammable materials in the air.
6) Lighting : The machine does not offer lighting devices. When necessary, install needed
lighting.
7) Overturn risk : Do not install the machine on the unstable stand or table. If the machine
drops, it may cause injury or severe impact on the machine. If the machine is suddenly
stopped or the external impact is imposed, the machine might be capsized.
2.4) Machine Operation
The machine body is attached with and stickers at each dangerous
part to emphasize safety instructions. With the full understanding of the safety
instructions, make sure to observe the following during machine operation:
1) Before turning on the power, read this manual thoroughly and have a full understanding of
machine operation.
2) Get properly dressed. Long hair, necklace, bracelet, or wide sleeve might be fed into the
machine during operation. Wear slip-free shoes to prevent slipping on the floor.
3) Check the moving scope of machine before its operation to find out whether the scope is
proper.
4) Keep hands and head away from the machine parts where accidents might occur (needle,
hook, thread take-up lever, pulley, etc.) during operation.
5) Do not remove the safety cover which protects pulley and shaft during machine operation
for user’s safety.
6) Cut the power supply before disassembling the electric box such as the control box, and
double-check that the power switch is“Off.”
7) Make sure that the power switch is“Off”when the upper shaft is manually rotated.
8) Stop the machine when the needle is replaced or when inspecting the machine after sewing
work is done.
9) Make sure to follow the cautions below. Otherwise, physical damage to the machine such as
malfunction and breakdown might result:
－Do not put articles on the S/M table.
－Avoid using a crooked needle or the needle with damaged tip.
－Use the presser foot appropriate to working conditions.

5.3.2) Bobbin Case Insertion/Removal
Open the hook cover and push the bobbin into the hook
by holding the bobbin case handle until you hear some
sound.
5.3.3) Tension Adjustment
1) Adjustment of Upper Thread Tension
Turn the tension adjusting nuts of the main and sub
thread adjusting devices clockwise, and the tension
of the upper thread will grow strong. Otherwise, the
tension of the upper thread will grow weak.
Adjust the thread tension in accordance with the
sewing conditions including sewing materials,
thread, and number of stitches.
2) Adjustment of Thread Take-up Lever Spring Tension
Adjust the tension of the thread take-up lever spring
by using the bolt on the main thread adjusting device
axis. If the bolt is turned clockwise, the thread take-
up spring tension will be strengthened. Otherwise,
the tension will be weaker. (The standard movement
volume is 6-8mm, and the standard tension is 30-
50g.)
3) Adjustment of Lower Thread Tension
If the bobbin case tension adjusting screw is turned
clockwise, the lower thread’s tension will grow
strong. If the bobbin case tension adjusting screw is
turned counter-clockwise, the lower thread’s tension
will grow weaker.
