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 heavy-
weight material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break re-
sulting 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-con-
ductor electronic parts and precise electronic circuits.
* The operating temperature of the sewing machine is between 5ºC and 40ºC. Do not use the sew-
ing 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.
