Sizing and installing Headband

1. Size the 20TGE headband by squeezing the top and bottom edges of rear buckle
with your thumb and forefinger. Decrease the size of headband by sliding band
through buckle.
2. Squeeze the buckle to disengage sizing mechanism, and place headband on your
head. Continue squeezing buckle while pulling headband down over your head.
Headband automatically adjusts to your size and locks when you release your grip
(see Figure 3). Headband should feel comfortable and snug.

If using the optional 20RTE ratchet headband, adjust the

size by turning the ratchet knob at the back of the headband.

3. Remove tissue paper from lens of respirator hood.
4. With clear lens facing you, insert headband into hood with headband snaps facing
front.
5. Engage four headband snaps into corresponding snap studs mounted in lens (see
Figure 4).

adjusting Crown Straps for Vertical Fit

To improve the comfort of 20TGE, adjust the crown straps vertically by repositioning the
headband keys in the crown straps. Vertical adjustment makes headband ride higher or
lower on the wearer’s head. To adjust the crown strap:
1. Rotate crown strap 90° until key dislodges from keyhole (see Figure 5).
2. Move key to desired vertical position.
3. Rotate crown straps 90° to secure key in keyhole.
4. Repeat steps 2-4 for other crown strap keys.

if Using Optional 20nC Chin Strap:

For most wearers, the headband holds the CC20E hood in place without a chin strap.
To install the optional chin strap:
1. Remove headband from hood.
2. Snap chin strap stud buttons into the holes on each side of the headband, inserting
from the inside.
3. Align holes on chin strap to stud buttons and pull downward to lock in place (see
Figure 6).
4. Place headband on your head. Adjust chin strap length with the plastic slide.
5. Remove headband from your head, and install into respirator hood.

if Using Optional 20LCL Lens Covers:

1. Apply optional adhesive-backed lens covers designed to protect the respirator’s
plastic lens. Apply 2-3 lenses at a time.
2. When a lens cover becomes soiled, remove it by pulling tab at edge of lens cover to
clear your vision.
