fied personnel.
UPGRADING FIRST STAGE REGULATOR
Do not tighten fittings or connectors when the system
is pressurized. Close the cylinder valve. Be sure noth-
ing blocks the regulator outlet. Relieve pressure from
the system by slowly opening the bypass valve. Failure
to follow this precaution may cause fittings or connec-
tors to rupture, resulting in serious personal injury or
death.
All repair procedures require that the regulator and Audi-
Larm is disassembled from the apparatus carrier. To do
this:
Wear eye protection throughout maintenance proce-
dures to avoid eye injury.
DISCONNECT AUDI-LARM FROM THE APPARATUS
CYLINDER
1. Be sure the cylinder valve is completely closed.
2. Be sure that nothing blocks the regulator outlet. Open
the bypass valve to relieve pressure in the system.
3. Close the bypass valve fully.
Do not disconnect the Audi-Larm coupling nut when
pressure is shown on the harness gauge. Always be
sure that you have released all pressure from the reg-
ulator. Removing the coupling nut with the regulator
pressurized may result in serious personal injury or
death.
4. Unscrew the Audi-Larm coupling nut from the cylinder
valve.
5. Leak-test after each repair.
REMOVING THE INTERMEDIATE PRESSURE HOSE
FROM THE FIRST STAGE REGULATOR CAP

and Instructions Manual supplied with the apparatus.
3. Ensure there are no leaks and the apparatus performs
properly. If the unit fails to meet any of the tests, the
condition(s) must be corrected before using the appa-
ratus.
Leak Testing should be performed if the SCBA fails any of
the inspection steps; following disassembly; or, as part of
a regularly scheduled maintenance procedure. The SCBA
must hold system pressure without leaks to provide ade-
quate protection. The component leak test procedure is
the first step in trouble-shooting. These tests ensure that
you do not have a leak. Leak testing quickly identifies
components which need repair or replacement.

DONNING THE APPARATUS
RECONNECT AUDI-LARM AND CHECK AIR MASK
FUNCTION
DONNING THE APPARATUS
1. Remove the facepiece from the case.
Do not use a cover lens in a high-temperature environ-
ment, such as firefighting. High temperatures may dis-
tort the cover lens. Or, moisture trapped between a
cover lens and the facepiece lens may condense and
distort vision. Always remove the cover lens before
donning the facepiece.
2. Check that the cylinder is fully pressurized.
If the cylinder is not full, the service time is reduced
accordingly & should not be used.
3. Reach inside the right shoulder straps and grasp the
redundant alarm and pressure gauge, slide left arm
through left shoulder straps.
4. Bend forward slightly, rest it on your back.
5. Attach the chest strap (optional).
6. Fasten the waist-strap and pull it tight for a snug fit.
7. As you straighten up, pull the shoulder strap tabs out.
Hike the unit up for a comfortable fit.
8. The shoulder straps and waist-strap ends must be
tucked in and lay flat across the body.
TESTING AND USING THE REDUNDANT ALARM, ICM
& AUDI-ALARM
1. Grasp the mask-mounted regulator and push the slide
button (top release button).
2. Check that the red
bypass knob is fully
closed (clockwise).
Note: To test the redundant alarm or ICM, see the
Redundant Alarm or ICM donning instruction. The alarm
should enter Test Mode.
3. Reach behind and
open the cylinder valve
fully. Listen for the
audible alarm to ring
briefly and redundant
alarm tones as pres-
sure in the system
increases.
4. As the pressure rises from 50 to 200 psig, both visible
and audible alarms activate automatically, indicating
that the alarms are functional and "cocked." When the
system is fully pressurized, the alarms enter the
Monitor (normal) mode.
If the alarm fails to ring, ICM or Redundant Alarm fails
to light and tone, do not use the apparatus. The SCBA
must be checked and corrected for proper operation
by an MSA trained or certified repairperson before
using. Failure to follow this precaution may result in
serious personal injury or death.
5. No air should flow from
the regulator. If it does,
repeat steps 1 and 2.
6. Check the Pressure Gauge, Redundant Alarm, ICM and
Cylinder Gauges. It should be within 110 psig for 2216
psig; 150 psig for 3000 psig; 225 psig for 4500 psig.
If your readings do not agree with these cylinder val-
ues, return the SCBA to an MSA trained or certified
repairperson.
7. Check for bypass oper-
ation. Grasp the red
knob and turn it
counter-clockwise.
Listen for airflow, then
turn it OFF. Close cylin-
der valve fully.

DONNING THE APPARATUS
8. Check for air leaks. Open cylinder valve fully to pres-
surize system, then close the cylinder valve and watch
the pressure gauge, Redundant alarm or ICM.
If the needle drops more than 100 psi in 10 seconds,
do not use the SCBA.
9. Crack the bypass valve slowly to bleed off pressure
until the Redundant alarm or ICM drops below:
530 psig - approximately (low-pressure system)
750 psig. approximately ( 3000psi System)
1175 psig – approximately (high-pressure system)
The Redundant alarm, ICM and audi-alarm will sound
and the gauge will illuminate until you turn the redun-
dant alarm OFF.
10. When the pressure falls below 200 psig, turn the alarm
off.
If the audi-alarm fails to ring, ICM or Redundant alarm
fails to light and tone, or fails to continuously ring to
200 psig, do not use the apparatus. The SCBA must be
checked and corrected for proper operation by an
MSA trained or certified repairperson before using.
Failure to follow this precaution may result in serious
personal injury or death.
Note: Before donning, check that the regulator sealing
ring is seated properly in its groove, and that it is not torn,
gouged, or nicked.
THE SPEED-ON HARNESS
Do not wear eye glasses under the facepiece. The
temples or sidebars on eye glasses will prevent an air-
tight seal. if you must wear glasses, install the specta-
cle kit. Failure to follow this precaution may cause
inhalation of contaminated air, resulting in serious res-
piratory injury or death.
1. Extend the facepiece
straps fully place neck-
strap around your neck
and don the facepiece
by inserting your chin
first.
2. Pull the head harness
completely over your
head and tighten the
lower (neck) straps.
3. Tighten the lower (neck) harness straps first, by pulling
them straight back, not out. Tighten the temple straps
the same way. Tuck in the ends of the straps so that
they lay flat across the head.
4. Push headband pad towards neck, tighten the front
strap for best visibility and fit. Tuck in the ends of the
straps so they flat across the head.
FACEPIECE FIT CHECK
Check the inhalation valve, inhale. If you do not
receive sufficient flow of air, do not use facepiece. The
facepiece must be repaired or replaced.
1. To check for facepiece
fit, hold the palm of
your hand over the inlet
facepiece adapter and
inhale. Hold your
breath at least 10 sec-
onds. The facepiece
should collapse and
stay collapsed against
your face. If it does
not, readjust the face-
piece and test again. If
this does not correct the leak, do not use the face-
piece.
2. Test the exhalation
valve, take a deep
breath and hold it.
Block the inlet face-
piece adapter with the
palm of your hand and
exhale. If the exhalation
valve is stuck, you may
feel a heavy rush of air
around the facepiece.
Note: You may need to exhale sharply to open the valve.
If this does not release the valve, do not use the face-
piece.
