Points to note when installing optional parts

• 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.
• 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.
• Installation of optional parts should only be carried out by a qualified technician.
• If any safety devices have been removed, be absolutely sure to re-install them to their original
positions and check that they operate correctly before using the machine.
