DONNING
4. Tighten the two lower
straps first by pulling
them straight back, not
out. Tighten the face-
piece until the mask is
snug against the face.
5. Tighten the two side
temple straps in the
same manner as
described in step 4.
Ensure that the face-
piece tabs are not
tucked under the face
seal.
6. Ensure the back of the
harness is centered on
the back of the head
and that the facepiece
seal provides uniform
pressure on the face at
all points. Readjust the
straps if needed.
FACEPIECE FIT CHECK
Note:
Check the inhalation valve by inhaling. If the face-
piece does not provide sufficient flow of air, do not use
facepiece. The facepiece must be repaired or replaced.
1. Check facepiece fit,
a. Detach the FireHawk Responder Regulator from the
intermediate pressure line.
b. Connect the regulator to facepice (See “Installing
the Push-to-Connect FireHawk Responder
Regulator” Section for instruction on installing
FireHawk Responder Regulator).
c. Take a deep breath and hold it for at least 10 sec-
onds. The facepiece should collapse and stay col-
lapsed against the face. Remove the regulator after
the test is performed. If it does not, readjust the
facepiece and test again.
If this does not correct
the leak, do not use the facepiece.
2. Test the exhalation valve.
a. Take a deep breath and hold it.
b. Connect the regulator to facepiece.
c. Exhale. If the exhalation valve is stuck, a heavy rush
of air around the facepiece may be noticed. A sharp
exhalation of air may be needed to open the valve.
Remove the regulator after the test is performed. If
this does not release the valve, do not use the face-
piece.
This device may not seal properly to the face if a
beard, gross sideburns or similar physical characteris-
tics (see NFPA-1500 and ANSI Z88.2) exist. An improp-
er facial seal may allow contaminants to leak into the
facepiece, reducing or eliminating respiratory protec-
tion. Do not use this device if such conditions exist.
The face-to-facepiece seal must be tested before
each use. Never remove the facepiece except in a
safe, non hazardous non-toxic atmosphere. Failure to
follow this warning can result in serious personal
injury or death.
3. Open the cylinder valve fully. Push in on the side buttons
of the Firehawk Responder Regulator to stop air flow.
4. Listen for any hissing or popping sounds from the
Audi-Larm Alarm. If heard, return the air mask to an
MSA trained or certified repairperson.
INSTALLING THE FIREHAWK RESPONDER
REGULATOR
1. Before installing the
FireHawk Responder
Regulator, be sure the
regulator is attached to
the intermediate pres-
sure line and the cylin-
der is turned on.
2. Grasp the FireHawk Responder regulator. Orient
bypass knob with pneumatic plug to the right. Insert
the regulator with pneumatic plug into the facepiece
by pushing inward.
DO NOT use the air mask unless the regulator is con-
nected properly. A regulator that is not installed cor-
rectly can separate from the facepiece unexpectedly.
Return the air mask to an MSA trained or certified
repairperson to correct the condition. Failure to follow
this warning can result in serious personal injury or
death.
