M-920 Visor frame & M-960 replacement Visor Pivot Kit
Note for M-100 & 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 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. Use a
tool if necessary. Remove frame from M-Series Headgear (Fig. 6b).
o 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.
o 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. Use a tool if necessary (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 up side 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 are correctly installed by raising and lowering the visor several
times. Ensure the visor stays firmly in the up (open) and down (closed) positions.

M-919 Visor Frame Buttons

The visor frame buttons are designed to stay slotted in the visor frame until broken, worn or damaged.
To replace broken or worn buttons, move the visor frame to the up (open) position. Remove visor from
frame as described in the previous section. Remove worn or broken button(s). You may need a tool
(e.g. pliers) to assist in removal. Install new buttons one at a time, ensuring they are correctly aligned
on each side of the frame. Fig. 7a shows how the buttons should be positioned (i.e. sloped flat tops are
both pointed in towards each other and not outwards on the frame). Re-install visor and ensure visor
buttons are firmly secured and flush to the visor frame (Fig. 7b). If the buttons do not seat flush to
frame, check that they were correctly installed. Reinstall if necessary.
