Setting the Spreader and Spreader Height
To time the spreader and to set its height:
1
Rotate the handwheel until the spreader is in its farthest left position.
2
Check the measurement from the bottom point of the spreader to the center
of the needle; it should measure 5 mm to 6 mm. The measurement from the
top of the needle plate to the bottom point of the spreader should be 14 mm.
3
Locate the spreader screw. This screw is located on top of the spreader
holder.
4
Loosen the spreader screw to move the spreader up and down and left to
right.
5
Manually move the spreader left to right until the measurement from the
bottom point of the spreader is 5–6 mm from the center of the needle.
6
Manually move the spreader up or down until the 14 mm measurement
between the top of the needle plate and the bottom point of the spreader is
achieved.
7
After the setting is correct, lightly tighten the spreader screw.
8
Turn the handwheel clockwise, to the right, until the spreader passes behind
the looper just to the left of the looper eye.
9
Verify that the spreader measures approximately 0.5 mm from the thinnest
part of the looper.
10
Tighten the spreader screw securely.
