3. Reverse order of the above steps to replace the grabber blade. When reinstalling
the grabber blade, orient the blade with the hook facing to the left, then slide it
into the Velcro wiper bar, the grabber blade guide, then through the front
blade cover.
4. At the location where the finger is pointing in Figure 4-2, just above the front
blade cover, you may have to direct the grabber blade into the top blade cover.
5. When the blade is completely installed into the covers and guides, check for
smooth blade movement before installing the screws to attach the grabber
blade to the grabber drive assembly at the entry into the arm casting.
Some cover and guide repositioning may be required to ensure smooth blade
movement.
6. Refer to the Grabber Adjustments section later in this chapter for checking and
properly adjusting the grabber blade position.
Trimmer Drive Assembly
Trimmer Cam
The trimmer cam is mounted on the rotary hook shaft in the rear bed. Replacing the
trimmer cam requires major embroidery head disassembly and critical adjustments
during reassembly. It is recommended that a technician trained in embroidery head
disassembly perform this procedure.
Trimmer Solenoid
NOTE; When the trimmer solenoid mount is moved, the movable knife home
position may become mis-adjusted. Refer to the movable knife home
position adjustment procedure after the solenoid is reinstalled.
1. Remove the head rear bed cover to gain access to the trimmer drive assembly.
2. Refer to Figure 4-3 and mark the position of the solenoid mount in its track on
the movable frame. This will aid in returning the assembly to its current position,
helping to keep the movable knife home position as close as possible.
3. Remove the right rear table top (with lamp assembly) and disconnect the
solenoid in-line connection from under the trimmer assembly.
4. Remove the socket head cap screw from the solenoid mount and lift the solenoid
and mount out together.
5. Loosen the set screw in the top of the solenoid mount then rotate the solenoid
out of the mount.
