6. ASSEMBLY
Wait at least 10 minutes after turning off the power switch and disconnecting the power cord from the wall outlet
before opening the face plate of the control box. Touching areas where high voltages are present can result in
severe injury.
Disassembly and assembly of the sewing machine
should only be carried out by a qualified
technician.
Turn off the power switch and disconnect the
power cord from the wall outlet before assembly,
otherwise 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.
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 slit, and your hand
may get caught.
