M-976 Head, Neck, and Shoulder Cover (for use with M-100/M-200/M-300)

The head, neck, and shoulder cover can be used to help keep the headgear and the wearer clean.
To install:
- Remove the black visor gasket by pulling straight out in small sections with the visor in the up (open)
position. Retain visor gasket.
- Insert headgear into head, neck, and shoulder cover such that the black gasket on the cover is
towards the visor of the headgear.
- Grasp the black gasket and align with the edge of the groove in the top of the visor. Starting on
one side press the gasket firmly into the groove in small sections. Both gasket ribs should be fully
inserted into the groove (Fig. 20).
- Pull air inlet in back of headgear completely through small hole in back of the cover.
NOTE: After using the head, neck, and shoulder cover ensure a visor gasket (M-921) is re-installed on
M-Series Headgear prior to use.

M-972 Flame Resistant Headgear Cover

The headgear cover can be used to help keep dirt, debris, overspray, etc off the headgear shell. The two
slits in the headgear cover are to accommodate the optional M-985 Earmuff Kit on the M-100, M-200
and M-300 Headgear. If you are using the earmuff kit, follow the procedures in this section for installing
the headcover when using the M-985 kit.
To install the headgear cover on M-Series Headgear (when optional M-985 Earmuff Kit is not being used):
- Remove the black visor gasket by pulling straight out in small sections with the visor in the up (open)
position. Retain visor gasket.
- To install the headgear cover, grasp the black gasket and align with the edge of the groove in the top
of the visor. Starting on one side press the gasket firmly into the groove in small sections. Both gasket
ribs should be fully inserted into the groove (Fig. 20).
- Pull headgear cover over product and loop over air inlet in back of headgear. The air inlet goes
through the hole in the back of the cover.
To install the headgear cover on M-100/M-200/M-300 when the optional M-985 Earmuff Kit is attached
to the headgear shell:
- Start with the earmuffs in the "Parked" position. To move the cups to this position, ensure the wire
bands are pulled outwards and then rotate cups to the top of the headgear. Care should be taken to
ensure the earmuff cushions stay clean. Refer to the M-985 section of these User Instructions for
additional information on "Usage", "Standby", and "Parked" positions.
- Remove the black visor gasket by pulling straight out in small sections with the visor in the up (open)
position. Retain visor gasket.
- Hold the cover over headgear oriented with the bright orange panel and black gasket pointed towards
the visor and the hole for the air inlet pointed towards the rear of the headgear.

- Push the earmuffs through the slits in the headgear cover one at a time.
- Pull headgear cover over product and loop over air inlet in back of headgear. The air inlet goes
through the hole in the back of the cover.
- With the visor in the open position, grasp the black gasket on the headgear cover and align with the
edge of the groove in the top of the visor. Starting on one side press the gasket firmly into the groove
in small sections. Both gasket ribs should be fully inserted into the groove (Fig. 20).
NOTE: After using the headgear cover, ensure a visor gasket (M-921) is re-installed on M-Series
Headgear prior to use.

M-956 Size Reducing Ratchet Comfort Pad

The size reducing ratchet comfort pad is available to provide additional comfort for wearers. This comfort
pad also can be used to improve fit and stability for smaller head sizes. To install, peel off backing on
comfort pad and attach to ratchet back plate. Ensure back plate is clean and dry prior to installation. Hold
pad in place with hand pressure for at least 5-10 seconds to ensure adhesion (Fig. 21).
M-985 Headgear-Mounted Earmuff Assembly (for use with M-100/
M-200/M-300)
The earmuff kit is an optional accessory for the M-100, M-200 and M-300 Series Headgear. The earmuff
kit cannot be used with the M-400 Series Helmets. The earmuff kit is fully assembled. The orange cups
are attached to wires and the wires are attached to black plastic attachment mounts. A set of screws is
included to attach the mounts to the headgear shell.
To attach the earmuffs to the M-100, M-200 or M-300 Headgear:
- Inspect the black plastic earmuff mounts and locate the "X" and "O" molded into the plastic. There is a
left side and right side mount (earmuff). As worn, the mount with the "X" on it should be on the right side
of the headgear and the mount marked with an "O" should be on the left side (i.e. "X" on the right, "O"
on the left). Fig. 22a depicts the location of the "X" and "O" markings on the mount.
NOTE: On the M-100 and M-200 Series Headgear only, the "X" and "O" markings on the inside of the
headgear shell used to assist with installing the faceshield head inserts can also be used as in indicator
for earmuff attachment. Match the marking on the earmuff mount with the corresponding marking on the
M-100/M-200 shell (i.e. match "X" to "X"). See Fig. 22b. There are no "X" and "O" markings on the inside
of the M-300 Series Headgear.
- Locate the earmuff attachment points on the outside of the headgear shell (Figs. 22c & d). Note on
the M-300 Series Headgear there are visible indents on the outside of the shell where the earmuffs
attach. On the M-100 and M-200, the indents may not be as visible on the outside of the shell.
- Use a pen or a screwdriver to gently push on the screw attachment points to start the hole (i.e. make
an indent). This will make it easier to thread the screws into the shell.
- Insert a screw into one of the holes in the mount and thread into the indentation on the headgear
shell using a screwdriver. Tighten until screw is flush to the mount and threaded in tight. Repeat
procedure with second screw.
- Test the mount connection to the shell by trying to wiggle the mount. If it moves or wobbles, further
tighten screws. The mount should be snug to the headgear shell.
- Attach the second mount to the other side of the headgear following the same procedure.
