3. Move the cursor to “Set B Point” and press
.
4. Press the manual frame-moving key to move the frame to a proper position.

B. Notes
1. When frame returns to the B point, there is only action on Y direction.
2. Frame will not move to the B point everytime when thread breaks at some position
and user presses the slow motion switch.
If the B point is set as in the following picture and the frame only moves above B
point (a zone, that is within the inner edge of the table), the machine will only have the
trimming action instead of moving frame to B point when you press slow motion button after
thread-breakage; only when frame is moving under B point (b zone, that is outside the inner
edge of the table), can the frame move to the B point after you press slow motion switch at
thread-breakage. In case of no action of the frame, please check the machine.
3. The position of the B point should be set as in the following picture, at the upper
edge of table notch, provided that it will not affect the threading operation. The reasons are as
follows:
(1) If B point is above the line, the frame will return to B point after pressing slow
moving key. There will be a long distance to go to the stop point after threading.
(2) If B point is under the line, threading will be greatly influenced.
