WARNING
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.
Other precautions
● Do not put the sewing machine
under the direct sunlight or in a
humid place.
Be aware that the following state can take place since the sewing machine incorporates
semi-conductor electronic parts and precise electronic circuits.
● 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.
● Do not wipe the sewing machine with solvent such
as thinner.
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.
● The safety device of the sewing machine will work
to stop the sewing machine in order to prevent the
generation of abnormal heat in the case the sewing machine is continuously engaged in sewing at
a low sewing speed for a long time or it is continuously engaged in sewing for a long time under the
high temperature environment. In this event, Start
and Stop button will not light.
The sewing machine will
return to working condition
after about 10 minutes.
* 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 re or electrical shock.
Stop!

* In general, the same thread is used for both needle and bobbin threads.
* Thin thread and needle will be used for light-weight fabrics and thick thread and needle will be used for heavy-
weight materials.
* Check that the combination of needle and thread is OK by trial sewing on the material which will be sewn.
* Knit needle is good for stretchy fabrics (such as knits) and synthetic fabrics.
* Use thread No. 30 - 90.
* When it is difcult to go over an overlapped section, guide the fabric by hand.
* When sewing “quilt patterns”, “decorative patterns” or “letters”, better nish will be ensured by using a knit needle.
