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.

absolutely sure to re-install them to their original 
positions and check that they operate correctly 
before using the machine. 

Any problems in machine operation which result 
from unauthorized modifications to the machine will 
not be covered by the warranty.
