11.5.2. Remove/Align Recoat Assembly
1. Close the mold top and unscrew the fitting of the injection tube from the mold top.
2. Remove the six 4-40 flange screws at the base of the recoat mold assembly.
3. Lift the recoat assembly straight up until it clears the recoat lamps. Keep track of the micro switch actuator
post, which may slide free from the assembly.
4. Before replacing the recoat assembly, make sure the baseplate, button of the mold assembly and the
micro switch actuator post are cleaned of any dirt particles.
5. Replace the micro switch actuator post by inserting the long end into the recoat assembly. Verify that the
post moves up and down freely.
6. Lower the assembly straight down over the recoat lamps.
7. Replace the six 4-40 flange screws. Lightly tighten two diagonal screws only to allow for adjustment of the
recoat assembly.

shown in Figure 66. Adjust the recoat assembly such that the fiber is centered in the bottom recoat
groove.
12. Repeat the previous step while viewing the fiber at the left edge of the recoat station.
