B. Thread Tensions
Set all thread tensions at a light level of tension. When pulled by hand, thread
should move freely through the needle, with little resistance. Make sure tensions
are not over tight. Too tight tensions will cause gathering of material.
C. Needle Height
See figure 09 (note: height specified in the diagram is for reference. Needle height
should be adjusted as necessary to properly work with the loopers.
D. Throat Plate Position
The throat plate should be set to the machine so that there is 1/ 16 inch (1.6mm)
between the point of an ent ering needle and the front of the needle slot (figure
10). An incorrectly set throat plate may cause needle breakage and damage the
feed dogs. To adjust, lift the presser foot. Swing out the cloth plate cover and
remove the throat plate. This gives access to the hidden screw holding the throat
plate base to the machine frame (figure 11). Now loosen the other three base
plate screws and adjust the position of the throat plate. Tighten just the three
available base plate screws to test the adjusted throat plate position. Once the
setting is correct, and the three available screws are firmly tightened, remove the
throat plate from the base. Tighten the last screw, and replace the throat plate.
E. Lower Looper Adjustment
As shown in Figure 12, when the lower looper is at the extreme left of travel, set
the distance (J) from the looper to the center of the needle at 9/64 inch (3.7mm).
To adjust, loosen the pinch screw indicated, and turn the looper holder on its arm.
If the distance is set to small or too large, skipped stitches may result when
sewing with certain types of thread.
The lower looper should clear the upper looper by the thickness of a piece of
paper (.004 inch or 0.1mm) as indicated on figure13. Too large a clearance will
break the needle or damage the looper.
