Notes during cleaning
• Turn off the power switch and disconnect the power cord before carrying out these operations. The
machine may operate if the treadle is depressed by mistake, which could result in injury.
• When cleaning the rotary hook, do not touch sharp parts such as the tip of the rotary hook directly
with your fingers. Otherwise injury may result.
• 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.
• When removing the needle plate, auxiliary needle plate and knife unit, use a screwdriver that
matches the size of the screw heads. If a screwdriver that does not match the size of the screw
heads is used, it may damage the screw heads and result in injury to the operator or damage to the
articles being sewn.
• Do not hold the machine head by the panel when tilting it back or returning it to its original position.
Otherwise, it may result in injury or damage to the sewing machine.
• Be sure to wear protective goggles and gloves when handling the lubricating oil and grease so that
they do not get into your eyes or onto your skin. Otherwise inflammation can result. Furthermore, do
not drink the oil or eat the grease under any circumstances. Diarrhea or vomiting may result. Keep
the oil and grease out of the reach of children.
Notes during maintenance and inspection
• Turn off the power switch and disconnect the power cord plug before carrying out inspection,
adjustment or repairs, or when replacing consumable parts such as the rotary hook or knives. The
machine may operate if the treadle is depressed by mistake, which could result in injury.
• If the power switch needs to be left on when carrying out some adjustment, be extremely careful to
observe all safety precautions.
• 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.
• Do not touch the face plate knives when opening the thread take-up guard cover. Otherwise it may
result in injury.
• When removing the needle plate, auxiliary needle plate and knife unit, use a screwdriver that
matches the size of the screw heads. If a screwdriver that does not match the size of the screw
heads is used, it may damage the screw heads and result in injury to the operator or damage to the
articles being sewn.
• Do not hold the machine head by the panel when tilting it back or returning it to its original position.
Otherwise, it may result in injury or damage to the sewing machine.
• Maintenance and inspection of the sewing machine should only be carried out by a qualified
technician.

responsible for any accidents or problems resulting from modifications made to the machine.
