2-5 TRIMMING MFS FOR ANVIS COMPATIBILITY
If the night vision goggles contact the MFS (as described in the fitting procedure), trim the MFS
following the procedure below.
Equipment, Tools, and Materials Required
•
Pencil
•
Rotary tool kit
• Drum, sanding
•
Band, abrasive
Procedure
1. Have the crewmember don the
helmet and attach the MFS.
2. Attach the night vision goggles to the
ANVIS mount.
3. Remove the lens caps and lower the
night vision goggles.
4. Mark a trim line on the shield by
tracing along the edge of the goggles
where they contact the shield.
Figure 2- 54 shows an example of
trim lines.
5. Stow the goggles; remove the shield.
NOTE: Trim the MFS with the edge beading left in place. You will cut through the edge
beading and the shield. Trim no more than necessary to allow the night vision goggles to
clear the MFS.
6. Using a rotary cutting tool, trim the shield along the marked trim line.
7. Reattach the shield and lower the night vision goggles. Ensure that the goggles clear the
shield and are properly positioned over the eyes.
NOTE: Replace the abrasive band of the sanding drum on the rotary tool as necessary.
