ENGLISH
Faceseal AS-101-10 and 102-10, Elastomeric:
The hook & loop fastener pieces should be joined and the protective backing film removed prior to
installation.
Wipe the inside of the visor surround with a mild cleaning solution as necessary to remove all dirt and
oil residue. When replacing an existing elastomeric faceseal, remove and discard the existing hook &
loop section from the visor surround. Place the exposed adhesive section on the inside of the flat
surface at the bottom of the visor surround (Fig. 15). Press the studs on the visor surround through
the corresponding holes in the faceseal (Fig. 16). Complete assembly and User Performance Check as
described in these User Instructions prior to use.
After donning, lower the visor until it snaps into place. The closing action should cause the faceseal
flaps to fold forward toward the users face. Do not pull the flaps out so they are folded outward
towards the neck and ears. Check for gaps between the rubber flaps and the face. If gaps are present
when using the AS-102-10 Medium/Large faceseal, switch to the AS-101-10 Small/Medium faceseal.
If gaps are present with the AS-101, do not use and select an alternative respirator system.
Visor Surround
Removal
Remove the faceseal as described above. Using a coin, rotate the quick-release visor pivots a quarter
turn in either direction to unlock the visor surround as shown (Fig. 18). Ease one side from the
headgear, releasing the pivot. Repeat this for the other side.
Replacement
Hold the visor surround in the raised position on the headgear. Press the pivots in and rotate them a
quarter turn in either direction using a coin. Ensure that the visor surround locks in the lowered position.

WARNING
Incorrect fitting of the visor will reduce face, eye and respiratory protection, and may result in
sickness or death.
Removal
Grip the upper edge of the visor surround at the center in one hand and the lower edge in the other
hand. Spread the edges apart and pop the visor from the center lugs of the visor surround. Gently push
the visor outward from the remaining lugs until it is completely released from the visor surround.
Replacement
Remove the protective covering from the new visor. With the longest edge toward the top of the
visor surround, slide the visor through lugs 1 and 2 as shown (Fig. 19). Continue sliding the visor so
that it rests in the three side lugs (3, 4 and 5) on the same side of the visor surround. Flex the visor
downward and insert under the upper, center lug (6) as shown (Fig. 20). Do not insert the visor under
the lower, center lug (12) yet. Flex the visor by pinching from top to bottom and insert under lugs 7 and
8 as shown (Fig. 21). Push the visor under lugs 9, 10 and 11 one at a time with your thumb as shown
(Fig. 22). Grip the lower edge of the visor surround at the center and twist downward until the visor
can be inserted under the lower, center lug (12) as shown (Fig. 23). Check that the visor is secured in
all 12 positions and there are no gaps at the visor periphery.
