Do not wipe the sewing machine with solvent
such as thinner.
Do not put the sewing machine under the
direct sunlight or in a humid place.
Be sure to use the sewing machine in the
temperature range from 5ºC to 40ºC.
If the temperature is excessively low, the
machine can fail to operate normally.
For the combination of the material and the thread and needle, in particular, refer to the explanation table
in "Replacement of the needle".
If the needle or thread does not match the material used such as in the case that an extra heavyweight
material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break resulting in an
unexpected personal injury.
WARNING
Other precautions
Be aware that the following state can take place since the sewing machine incorporates semi-conductor
electronic parts and precise electronic circuits.
* The operating temperature of the sewing machine is between 5ºC and 40ºC. Do not use the sewing
machine under the direct sunlight, near the burning things such as a stove and candle, or in a humid
place. By so doing, the temperature in the interior portion of the sewing machine can rise or the coating
of the power cord can melt, causing fire or electrical shock.
When the sewing
machine is soiled,
put a small quantity
of neutral detergent
on a piece of soft
cloth and carefully
wipe off the sewing
machine with it.
Do not dispose of electrical appliances as unsorted municipal waste, use separate collection
facilities.
Contact your local government for information regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into
the groundwater and get into the food chain, damaging your health and well-being.
When replacing old appliances with new once, the retailer is legally obligated to take back your
old appliance for disposal at least for free of charge.

Connecting the machine
Before connecting the power
supply, make sure that the voltage
and frequency shown on the rating
plate is conforming with your
mains power.
Place the machine on a stable
table.
1. Connect the power cord to the
machine by inserting the 2-hole
plug into the mains plug socket.
2. Connect the power line plug to
the wall outlet.
Connect the foot controller plug
if you use.
3. Turn on the power switch.
4. The sewing lamp will light up
when the switch is turned on.
5. After switching off, it will take
some time to consume the
residual power in the circuitry.
The light does not turn off
immediately after switching off
the power. This is normal
phenomenon for an energy
efficient appliance.
Attention:
Always make sure that the
machine is unplugged from power
source and the main switch is off
("O"). when the machine is not in
use and before inserting or
removing parts.
Polarized plug information
Foot Control
This appliance has a polarized
plug (one blade wider than the
other), to reduce the risk of
electrical shock; this plug will fit in
a polarized outlet only one way. If
the plug does not fit fully in the
outlet, reverse the plug. If it still
does not fit, contact a qualified
electrician to install the proper
outlet. Do not modify the plug in
any way.
With the sewing machine turned
off, insert the foot control plug into
its connector on the sewing
machine.
Turn on the sewing machine, and
then slowly depress the foot
control to start sewing. Release
the foot control to stop the sewing
machine.
Even if you use foot controller,
start/stop button is available.

1. Place the thread and spool
cap onto the spool pin.
For smaller spools of thread,
place spool cap with the small
side next to the spool or use
the small spool cap.
2. Snap the thread into the
thread guide.
3. Wind the thread clockwise
around the bobbin winder
tension discs.
4. Place the thread end through
one of the inner holes in the
bobbin as illustrated and place
empty bobbin on the spindle.
5. Push the bobbin to right.
When the bobbin winder
spindle is pushed to the right,
the number display will blink on
and off while displaying " ".
It will disappear when the
bobbin winder spindle is
pushed to the left, which is the
"sewing position".
6. Hold the thread tail securely in
one hand.
7. Press on the foot control or the
Start/stop button to start
winding the bobbin.
8. After the bobbin has wound a
few turns stop the machine
and cut the thread near the
hole of the bobbin. Continue
filling the bobbin until it is full.
Once the spool is full, it rotates
slowly. Release the pedal or
stop the machine. Push the
bobbin winder spindle to left.
9. Cut the thread and then
remove the bobbin.
Winding the bobbin
Note:
- When the bobbin winder switch
is placed on the right "bobbin
winding position", the buttons
will not work. To start sewing,
push the bobbin winder switch
to the left "sewing position".
- If you find the bobbin winding
the thread unevenly, you can
adjust the height of the winder
tension disc (3) to improve it.

Standard presser foot pressure
set at "2".
The presser foot pressure of
the machine has been pre-set
and no need for change unless
sewing particular type of fabric
(light-or-heavy weight).
If you do need to adjust the
presser foot pressure, turn the
presser adjusting screw by
ones finger.
For sewing very thin fabric,
loosen the pressure by turning
the screw counterclockwise to
move the screw upward and

take out. By that time, just turn
the screw clockwise, it could be
locked back and readjust the
pressure.
For heavy fabric, tighten the
pressure by turning the screw
clockwise to move the screw
downward and the pressure
increased. Once screw could
not be moved any further, it has
been reached the bottom,
please do not turn any more.
