							THREADING TIPS FOR 5-THREAD SAFETY STITCH: 
 
• Be sure to follow the threading sequence outlined above. 
• Make sure needles are set-up in positions D, and B for 5-thread safety 
stitch.  This is very well illustrated in your manual on page 15. 
• If you would prefer a wider 5-thread safety stitch, place the overedge 
needle in the A rather than the B position when threading the blue 
overedge needle.  This will widen the overedge finish on the edge of your 
fabric. 
• When inserting the needle in positions A or B, loosening both screws A 
and B will facilitate inserting and removing needles. 
• Always reset the tension dials by re-selecting the stitch after threading the 
serger.
