3. DISASSEMBLY
Turn off the power switch before disassembly, oth-
erwise the machine may operate if the treadle is
depressed by mistake, which could result in injury.
* When using a clutch motor, the motor will keep
turning even after the power is switched off as
a result of the motor's inertia. Wait until the
motor stops fully before starting work.
Disassembly of the sewing machine should only be
carried out by a qualified technician.
Use only the proper replacement parts as specified
by Brother.
