USE OF THE RESPIRATOR
The following information provides the basic steps for use of the AIR-PAK
X3 SNAP-CHANGE SCBA. Training and practice with the equipment are
required before use to assure that the user is completely familiar with
the operation of the respirator.
The AIR-PAK X3 SNAP-CHANGE SCBA must be worn over protective
garments such as fire fighting turnout gear, but may be worn under en-
capsulating protective garments such as hazardous material (haz-mat)
suits. Determine what other protective gear will be used and don the
SCBA and the facepiece accordingly.
The AV-3000 HT Facepiece is made of heat resistant materials. When us-
ing the AV-3000 HT Facepiece in applications where high heat may occur,
follow all training and operating procedures relating to heat exposure. To
avoid possible injury, the respirator user must understand the hazards of
heat exposure including temperature, duration and repeat exposure. If
respirator use is expected at temperatures near or below freezing, or if
respirator is to be used after being kept at temperatures near or below
freezing, refer to LOW TEMPERATURE OPERATION Section for additional
information and supplemental procedures.

manufacturer for placing arms through shoulder straps and freeing
the respirator from the bracket.

case on the ground or level surface and open the case. Secure the
regulator in the regulator holder. Proceed as shown in FIGURES* 9-A
thru 9-F.
a) Adjust the shoulder straps to their full outward (fully loose) posi-
tion.
b) Spread shoulder straps and fold open waist pad. Stand the res-
pirator on the cylinder valve with cylinder toward you and the
shoulder straps away from you.
