6. DISASSEMBLY

Wait at least 5 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 should only be carried out by a
qualified technician.
Turn off the power switch before carrying out
disassembly. If the treadle is depressed by mistake,
the sewing machine might start operating and injury
could result.
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. If the oil
and grease get into your eyes or onto your skin,
inflammation can result.
Furthermore, do not drink or eat the lubricating oil or
grease. They may cause diarrhea or vomiting.
Keep the oil out of the reach of children.
