● Do not wipe the sewing machine with solvent such as
thinner.
When the sewing machine
is soiled, put a small quan-
tity of neutral detergent
on a piece of soft cloth
and carefully wipe off the
sewing machine with it.
● Be sure to use the sewing machine in the tempera-
ture range from 5ºC to 40ºC.
If the temperature is excessively low, the machine
can fail to operate normally.
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 resulting in an unexpected personal injury.
Other precautions
● Do not put the sewing machine under the direct sun-
light 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.
* 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 tempera-
ture in the interior portion of the sewing machine can rise or the coating of the power cord can melt, causing re or
electrical shock.
