2 Timing of the retainer looper to the needle    

When the needle, moving from the top to bottom of its stroke, enters the triangle of the 
looper thread, the retainer looper should be at the extreme right end of its travel. 
To adjust the retainer looper left to right, loosen screws A first.    With the retainer looper 
at the extreme left end of its travel, set the clearance 
between the retainer looper and the right side of the 
looper at approximately 0.5mm.  Then set the clearance 
between the retainer looper and the top surface of the 
looper blade at 0.1mm.  After this adjustment is made, 
tighten screws A.
