Notes on safety
Notes during use
• Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the
wall outlet before opening the control box cover. Touching areas where high voltages are present
can result in severe injury.
• Do not allow the machine to come into contact with liquids. Otherwise it may cause fire, electric
shocks, or operating problems.
• If any liquid gets inside the sewing machine (machine head or control box), immediately turn off the
power and disconnect the power plug from the electrical outlet, and then contact the place of
purchase or a qualified technician.
Notes on the operating environment
• Do not connect anything to the USB port other than the USB media. Otherwise, problems with
operation may result.
• Use the sewing machine in an area which is free from sources of strong electrical noise such as
electrical line noise or static electric noise. Sources of strong electrical noise may cause problems
with correct operation
• Any fluctuations in the power supply voltage should be within ±10% of the rated voltage for the
machine.Voltage fluctuations which are greater than this may cause problems with correct operation.
• The power supply capacity should be greater than the requirements for the sewing machine's power
consumption. Insufficient power supply capacity may cause problems with correct operation.
• The ambient temperature should be within the range of 5℃ to 35℃ during use.Temperatures which
are lower or higher than this may cause problems with correct operation.
• The relative humidity should be within the range of 45% to 85% during use, and no dew formation
should occur in any devices.Excessively dry or humid environments and dew formation may cause
problems with correct operation.
• In the event of an electrical storm, turn off the power and disconnect the power cord from the wall
outlet. Lightning may cause problems with correct operation.
Notes during installation
• Do not connect the power cord plug until installation is complete. The machine may operate if the
treadle is depressed by mistake, which could result in injury.
• Secure the table so that it will not move when tilting back the machine head. If the table moves, it
may crush your feet or cause other injuries.
• Use both hands to hold the machine head when tilting it back or returning it to its original position. If
only one hand is used, the weight of the machine head may cause your hand to slip, and your hand
may get caught.
