out the approval of the manufacturer. Such alterations will
voi the NIOSH approval.
NFPA 19 1, 2002 EDITION COMPLIANCE INSPECTION
DO NOT inspect the apparatus before cleaning if there
is a danger of contacting hazardous contaminants.
Clean and sanitize first, then inspect. Failure to follow
this warning can cause inhalation or skin absorption
of the contaminant and result in serious personal
injury or death.
An SCBA cannot be upgraded until the following
inspection and all required changes have been com-
pleted.
Inspect the entire air mask after it is cleane an sani-
tize . NFPA-1500, as well as ANSI Stan ar s Z88.2 an
Z88.5, escribe three levels of inspection proce ures that
are to be performe . Refer to these ocuments or to an
inspection program prepare by a health professional in
establishing an inspection program.
Note: An NFPA 1981, 2002 e ition compliant air mask
will have the URC fitting on the Au i-larm™ Au ible
Alarm, Hea s-Up-Display (HUD) Receiver an HUD
Transmitter or an ICM Tx or ICM TxR Integrate PASS.
Prior to installation of the FireHawk M7 Upgra e Kit, the
air mask must be upgra e to be compliant with the 2002

nificant wear. Some accessories an components may
not be approve for use on an NFPA 1981, 2007 e ition
compliant unit. Consult the NIOSH approval label
(P/N10083874) inclu e in the upgra e kit for a complete
list of approve components.
If any component of the air mask being upgraded is
missing or needs to be replaced due to wear or dam-
age, replace the affected component before installing
the FireHawk M7 Upgrade Kit. Used, worn, or dam-
aged parts can result in serious personal injury or
death.
INSPECTION AND FUNCTIONAL TEST OF THE NFPA
19 1, 2002 EDITION COMPLIANT AIR MASK
In a ition to the inspection of components require prior
to the up gra e, the following general inspection of the
apparatus must be performe before installing the
FireHawk M7 Upgra e Kit.
1. Don the air mask following the instruction proce-
ures. These steps make up the air mask
functional test.
2. If all steps are performe successfully, remove the air
mask an inspect it following the steps below.
3. Facepiece
a. Inspect the facepiece for rubber eterioration,
irt, cracks, tears, holes, or tackiness.
b. Check the harness hea straps for breaks, loss
of elasticity, or missing buckles or straps. Check
the straps for signs of wear.
c. Inspect the lens for cracks, scratches, an a tight
seal with the facepiece rubber.
. The exhalation valve must be clean an operate
easily. Reach into the facepiece. Push an
release the valve stem several times. The valve
must move off the seat an return when release .
e. Inspect the facepiece inlet regulator coupling for
amage. Also check to be sure that the spi er
gasket an valve isc are present, clean, an not
amage .
f. Inspect the facepiece rubber behin the
Nightfighter Hea s Up Display receiver bracket
or Clear Comman bracket for holes or tears.
4. Cylin er Gauge
a. Be sure that the gauge nee le an face is visible
through the lens.
b. Be sure the gauge stem is not bent.
5. Au ible Alarm with URC Assembly
a. Check that the alarm rings briefly when the
cylin er valve is opene .
b. Check that the bell is in the proper alignment an
is fastene securely.
c. If the bell is loose, remove the alarm from service.
. Unscrew the Au i-Larm Au ible Alarm with URC
Assembly coupling nut from the cylin er valve. In-
spect the coupling nut for threa amage. Also be
sure there is an o-ring, an that it is not amage .
Replace the insert o-ring if it is amage .
e. Check Au i-Larm Alarm with URC Assembly an
URC Assembly relief valve for any amage.
f. Check relief valve label for amage. Check for
missing or lose label. Ensure that relief valve
ports are showing. If any amage, remove air
mask from service an replace relief valve.
6. High Pressure Hoses
a. Check the high pressure hose between the Au i-
Larm Au ible Alarm an the first stage regulator.
Look for cuts or severe abrasions. If present,
replace the hose. The hose shoul be securely
attache to the first stage regulator an Au i-Larm.
b. Check the high pressure hose between the remote
gauge an the first stage regulator. Look for cuts or
severe abrasions. If present, replace the hose.
7. Interme iate Pressure Hose Inspection
a. Inspect the interme iate pressure hose between the
first stage regulator an the secon stage regulator.
The hose must be free of severe abrasions, wear,
cuts or amage.
b. Inspect the connection between the first stage inter
me iate pressure hose an the secon stage inter
me iate pressure hose. The hoses shoul swivel
easily. The connection shoul be free of amage.
c. Inspect rubber washer for eterioration, irt, cracks,
tears, or tackiness.(for quick connect hoses only)
8. Cylin er
a. Inspect the cylin er valve for signs of amage.
The valve may be opene slightly to be sure it
operates properly. Be sure to fully close the valve.
b. Inspect the cylin er bo y for cracks, ents,
weakene areas, or signs of heat-relate
amage. If the cylin er is amage , return it to
an MSA service Center. Call 1-800-MSA-2222
for instructions.
Note: Check the hy rostatic test ate on the cylin er
approval sticker locate on the cylin er neck. Composite
cylin ers must be teste every three years.
After all inspections have been complete successfully,
install the FireHawk M7 Upgra e Kit
Only MSA certified technicians are authorized to
install the NFPA 2007 Upgrade Kit.

UPGRADE INSTRUCTIONS

INSTALLATION OF FACEPIECE MODEL NUMBER
LABELS
If the facepiece has been upgra e or if it oes not have
the mo el number escribe below, a new mo el number
label must be applie to the facepiece. New CBRN compli
ant facepieces will have the new mo el number engrave
on them an a label will not be require .
I entify the facepiece mo el number label from the set of
three facepiece labels.
This table i entifies the proper mo el number label.
Apply the label to the
insi e of the facepiece at
the bottom left of the lens.
Discar the remaining
unuse labels. Ensure that
the mo el number is ori-
ente properly an can be
clearly seen from the out-
si e of the lens.
INSTALLING THE FIREHAWK M7 HUD
Note: Once the facepiece has been upgra e , an HUD
mounting bracket installe , the FireHawk M7 HUD is

locations on the battery cartri ge. Follow the notations
on the cartri ge to ensure proper battery orientation.
2. Insert the battery cartri ge into the battery tube on the
FireHawk M7 HUD.
3. Before installing the battery cap, verify that the o-ring
is in place an free of amage an ebris. If the o-ring
is missing or amage , replace o-ring. Failure to o so
may allow moisture or contaminants into the battery
tube an cause the evice to not function properly.
4. Threa the battery cap on to the battery tube of the
FireHawk M7 HUD (clockwise). Han -tighten cap until
snug. Do not over-tighten battery cap.
5. As the battery cap makes contact with the battery car-
tri ge, verify that the FireHawk M7 HUD isplay turns
on an goes through its start up sequence before
turning off. The yellow LED shoul not be flashing.
Use only Rayovac 24 LR03, Rayovac Ultrapro 4R03,
Energizer E92, Energizer Industrial EN92, Duracell
MN2400, or Duracell Pro Cell MN2400 alkaline batter-
ies in the FireHawk M7 HUD. Use of other batteries, or
acombination of batteries from different manufactur-
ers, will affect the performance of unit and void the
Intrinsic Safety Approval.
Attaching the FireHawk M7 HUD to the Mounting
Bracket
1. Align the metal tab on
the FireHawk M7 HUD
with the metal plate on
the front e ge of the
bracket.
2. Rotate the M7 HUD so
that the tab fits into the
slot behin the thumb-
screw.
3. Finger tighten the thumbscrew.
DO NOT use a screwdriver to tighten the thumbscrew.
REMOVING PRESSURE GAUGE OR INTEGRATED
