technique may result in injury to personnel performing the

Sequence of Trim Events
During the trim function, many events occur with a set timing sequence to enable
the trimming action to be successful. The following steps provide you with a very
general outline (and sometimes brief descriptions) of the major actions that take
place during the trim function.
1. While embroidering a design, the trim function is initiated when the embroidery
peripheral detects the design code for: a color change, a trim, a set number of
consecutive jump stitches, or the end of design.
2. The heads will slow to about 100 stitches per minute, which is the speed range
for the trimming action.
3. The picker engages with the current thread loop as it is being formed in the hook
and bobbin area. This process is required to provide the correct length for
restarting the embroidery next time this thread color is used.
4. The movable knife comes forward to the ready state for trimming. During its
forward movement, it separates the top thread from the thread that is looped
around the hook. It is here where it "selects" the top thread and bobbin thread
for trimming.
5. When the movable knife returns to the "home" position, the selected threads
will be cut between the movable knife and the adjustable fixed knife.
