OPERATION
1. Check for facepiece fit
by holding the palm of
one hand over the inlet
connection and inhal-
ing. Hold breath at
least 10 seconds. The
facepiece should col-
lapse and stay col-
lapsed against the
face.
If it does not, adjust the facepiece and test again.
If adjustment does not provide a proper seal, do
not use the facepiece.
2. Test the exhalation
valve, take a deep
breath and hold it.
Block the inlet connec-
tion with the palm of
one hand and exhale. If
the exhalation valve is
stuck, a heavy rush of
air may be felt around
the facepiece.
Note:
It may be necessary to exhale sharply to open the
valve. If this does not release the valve, do not use the
facepiece.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see ANSI Z88.2). An improper face-to-
facepiece seal may allow contaminants to leak into
the facepiece, reducing or eliminating respiratory pro-
tection. Do not use this device if a proper face-to-
facepiece seal can not be achieved. The face-to-face-
piece 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.
CONNECTING THE AIR SUPPLY HOSE TO THE
ATTACHMENT HOSE
1. Verify that the cylinder valve knob is completely
closed (clockwise).
•
DO NOT open the cylinder valve knob unless in an
emergency escape application. Doing so while
connected to an air source could result in depleted
cylinder pressure and decreased escape time.
•
DO NOT enter any area which requires an escape
greater than the service life of the cylinder.
Cylinder life varies with the work rate of the indi-
vidual and may be shorter with heavy work loads.
Failure to follow these warnings can result in serious
personal injury or death.
2. Push the Firehawk
Regulator release but-
tons to shut off the reg-
ulator.
3. While pressing the release buttons, pull the regulator
out of the stand-by mount.
4. Connect the air supply
hose to the attachment
hose.
5. Pull on the quick-disconnect plug and socket to verify
that the hoses are securely attached.
6. Listen and inspect for
air leakage from the
Firehawk Regulator,
cylinder and valve
assembly, and hose
connections.
DO NOT use the respirator if it exhibits leakage.
Return the respirator to an MSA trained or certified
repairperson to correct the condition. Failure to follow
this warning can result in serious personal injury or
death.
