faceshield frame. Lift the lens from the frame while sliding it out
from under the lower post.
6) The L-136 is the Cam Spring Set.
The cam spring set should be
replaced when the faceshield will no longer stay in the up or down
position or when the faceshield is loose in the closed position. The
springs should only be removed if damaged and should not be removed
for cleaning. To remove the cam spring set:
a. Insert a flat blade screwdriver under the spring and lift the spring
out.
7) The L-134 is the Latch Kit.
Replace the latches when they are broken
or missing. Do not use the headgear until the latches are in place. To
remove the latches:
a. Use a pliers to grasp the base of the L-shaped latch.
b. Pull forcefully on the latch until it is removed.
