The respirator headband must be adjusted to achieve a snug, comfortable, and balanced fit
prior to entering the work environment. Increase the headband circumference by pressing
the center button and turning the ratchet adjustment knob counter-clockwise as shown in
number. Reduce the headband circumference by rotating the ratchet knob clockwise. Take
care to not kink or distort the head strap while adjusting the headband circumference.
Improving the forward/backward balance of the respirator is accomplished by locating the
headband on either the front or rear set of tabs of the mounting bracket attached to the
respirator frame. Refer to 3.2.3 Illustration 2+3.
The respirator can be used in conjunction with corrective prescription spectacles and
compatible hearing protection. (Ear plugs or custom molded ear plugs)
CAUTION
Corrective prescription eye protection may transmit impacts from high-speed particles, thus
creating a hazard to the wearer.
Do not hold or suspend the respirator by the neck cape or headband.
Adjust the neck cape using the toggle fastener to tighten the drawstring and provide a
comfortable seal against the neck. See section 3.3.
Firmly close the visor and check that the neck cape inflates slightly, indicating positive
pressure within the helmet. If the neck cape does not inflate, perform step 7 again and also
check that the neck cape is correctly attached to the respirator chassis. See section 5.3 neck
cape replacement.
The neck capes are secured by fasteners (snaps). The boss side of the snap fastener attached
to the respirator frame are replaceable (refer to the Parts Order List at the end of this
document). The snaps installed on the neck cape are not replaceable, if they are damaged a
replacement neck cape. If new neck cape fasteners are required on the helmet, remove the
old self-tapping screws and cape, screw bosses, and install new parts.
WARNING
Penetration of ambient air!
Make sure that the neck cape is securely and firmly in place before each use.
