Respirator Assembly - Bullard CC20E Manual Del Usuario

RESPIRATOR ASSEMBLY

1. Size the 20TGE headband by squeezing the top and bottom edges of rear buckle with your thumb and fore-
finger. 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 squeez-
ing 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.
NOTE: 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.
