WARNING
For the combination of the material and the thread and needle, in particular, refer to the explana-
tion 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-conductor electronic parts and precise electronic circuits.
● Be sure to use the sewing ma-
chine in the temperature range
from 5ºC to 40ºC.
If the temperature is excessive-
ly low, the machine can fail to
operate normally.
* 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.
● 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 sew-
ing machine with it.
● Safety device
In the case the sewing machine continuously per-
forms sewing under the following conditions, the safe-
ty device will automatically kick in to stop the sewing
machine to prevent the sewing machine from being
abnormally hot.
If the sewing machine continuously performs sew-
・
ing at a low speed for an extended period of time,
or under a hot environment:
The safety device automatically returns to its
→
normal state approximately 30 minutes after it
has stopped the sewing machine. Then, you can
normally use the sewing machine again.
If the sewing machine continu-
・
ously performs sewing while the
motor is abnormally overloaded
such as in the case thread en-
tanglement has occurred:
Remove thread and cloth
→
chip entangling in the bobbin
case, hook, etc.
