M-925 and M-927 Visors

- With the visor frame in the down position (M-100, M-200 & M-300), release the visor frame buttons
by pushing the buttons outward from inside the visor frame, one "click" (Fig. 5a). Move the visor
frame to the up (open) position and pull on visor to remove from frame (Fig. 5b). If using the M-400,
it may be easier if the visor frame is in the up (open) position to release the buttons and remove the
visor.
- With the visor in the up (open) position, install a new visor by inserting visor into the groove in the
frame, lining up the notches in the visor with the visor frame buttons. Ensure visor is fully seated in
the groove (Fig. 5b).
- Push visor frame buttons closed to lock visor in place. The buttons should make an audible "click"
when fully seated in the frame (Fig. 5c). Ensure visor buttons are firmly secured and flush to the visor
frame (Fig. 5d). If the buttons do not seat flush to frame, remove and reinsert.
- Ensure the visor gasket is present and securely inserted into the groove in the top of the visor frame
(See M-921 in this section).

M-920 Visor Frame & M-960 Replacement Visor Pivot Kit
NOTE: For M-100, M-200 & M-300 Series users: You must first detach the faceseal from the suspension
headband. Re-attach faceseal before use. See M-935, M-936, & M-937 Faceseals in this section for
additional information.
- Fig. 6a shows the pivot kit. From the top down, the part marked "3M" is the post (1), the next part is
the "back plate" (2), and the bottom part in the Fig. 6a is the "metal spring clip" (3).
- With the headgear upside down and the visor frame in the up (open) position, pull down on metal
spring clips (towards inside of headgear) until they touch the back plate. Pull out to remove. Gently
use a tool if necessary (e.g. flat-blade screwdriver). Remove frame from M-Series Headgear (Fig. 6b).
If replacing frame or pivot kit, remove post with red "3M" from visor frame by placing the frame on the
edge of a table, resting on the post (i.e. 3M is facing toward you), and press down forcefully on the visor
frame with heel of hand.
If replacing pivot kit, push back plate out from shell slightly (towards outside of headgear) and slide out
from slot on headgear shell to remove. Gently use a tool if necessary (e.g. flat-blade screwdriver) (Fig. 6c).
- To re-install the visor frame and pivot kit, insert "3M" post into visor frame. Ensure "3M" is positioned
such that it is right side up when worn and not upside down.
- Install back plate into the headgear shell. When installing the "wind mill" pattern should be facing
outwards and the "M-960" marking will be located on the bottom of the plate. Install rounded edge
first and slide completely into the slot (Fig. 6d). Gently push down on back plate to ensure it is flush to
bottom of slot.
- Line up visor frame over attachment slots and slide spring into place. With the post and back plate
engaged, the visor frame should be in the fully open or fully closed position before the spring is
installed (Fig. 6e).
- Verify the visor frame and pivot kit is correctly installed by raising and lowering the visor several
times. Ensure the visor stays firmly in the up (open) and down (closed) positions.
