trimmer cam groove by pushing the protruded end of the pin inward with a flat
bladed screw driver.

the cam is damaged beyond use, factory service is recommended to replace it.

is reinstalled.
12. Repeat this procedure to check again for unrestricted cam assembly movement.
Checking "Head Up" Position
Before checking/adjusting movable knife "home" or "select" positions, you should
check the cam positions at head up.
1. Remove the embroidery head rear bed cover to expose the trimmer camming
mechanisms shown in Figure 4-7.
WARNING! Keep clear of the moving parts that are exposed
during the operation of the next step(s).
2. Go to the HEAD TIMING MENU and press to turn HEAD TIMING ON. Put the
heads to the "head up" position by pressing the key combination.
3. Locate the holes in the rear of the cams (see Figure 4-7) and check that they are
facing nearly straight upward. If the holes are not facing close to straight
upward, the select position may require adjustment. Refer to the select position
adjustment in this chapter.
