IMPORTANT NOTICE
•
Note: A thorough understanding of the SCBA is essential
before attempting to service or maintain this SCBA. An
Operation and Instructions Manual is supplied with each
new SCBA. Refer to the Operation and Instructions for
specific user information, such as NIOSH Approval
Information, donning and doffing, or cleaning and disinfecting.

NOTE: SCBA CRITICAL REPAIR PARTS CONTAINED
WITHIN THE BLACK OUTLINED BOX MUST ONLY BE
INSTALLED BY C.A.R.E. TRAINED AND CERTIFIED
REPAIR TECHNICIANS AND TESTED WITH AN MSA
APPROVED DYNAMIC FLOW TESTER.
Follow the procedures and maintenance schedules given
in the apparatus instruction manual and as specified
below. If an apparatus does not pass all tests, remove it
from service until it has been repaired and passes all tests.
Do not attempt repairs beyond those specified in this
manual. Only trained or certified personnel, authorized
by MSA, are permitted to maintain and repair this
apparatus.
GENERAL NOTES
Breathing apparatus must not be repaired beyond the
manufacturer's recommendations. 29 CFR Part
1910.134, Par. (f) (4) makes these requirements clear:
Replacement or repairs shall be done only by experienced persons with parts designed for the respirator.
No attempt shall be made to replace components or to
make adjustment or repairs beyond the manufacturer's
recommendations. Reducing or admission valves or
regulators shall be returned to the manufacturer or to a
trained technician for adjustment or repair.
Some maintenance and repair procedures involve techniques and skills you will use over and over again.
Whenever you use them, follow the general notes below.
Since there are several models in the series, consult the
instruction manuals that come with your SCBA.
IMPORTANT
You must read and understand the General Notes,
Warnings, and Cautions below before performing
Disassembly and Repair. General Notes is a collection
of procedures common to many repairs.
Failure to follow this warning may result in serious
personal injury or death.
WARNING
This symbol identifies a potentially hazardous situation,
which if not avoided may cause serious injury or death.
Heed the warning. Follow its instructions exactly.
INTRODUCTION
CAUTION
This symbol identifies a potentially hazardous situation,
which if not avoided will result in major or minor injury. It
also may be used to alert against unsafe actions. Read
and understand the implications of the caution. Carefully
consider its relevance to your actions.
This C.A.R.E. Maintenance Binder contains all maintenance
procedures for this SCBA. You must be thoroughly familiar
with the SCBA before performing any maintenance.
• This SCBA will perform as designed only if used and
maintained according to the manufacturer's instructions. You must read and understand these instructions before trying to use or service this product. We
encourage our customers to call for information on
this product before using it.
• If the SCBA does not perform as specified in this
TAL 8001 (L) Rev. 9 - 10002263
manual, it must not be used until it has been repaired.
Do not alter, modify, or substitute any components
without the approval of the manufacturer. Such alterations will void the NIOSH approval.
Inspect the SCBA regularly and maintain it according
to the manufacturer's instructions. Repairs must be
made by properly trained personnel only, and according to the procedures in this Binder.
Test the performance of the entire apparatus as a unit
to ensure that all parts perform according to MSA
specifications. For example, if you are testing a QuickFill® System apparatus, test it as a Quick-Fill System
unit. If the apparatus is a dual-purpose apparatus, test
it as a dual-purpose unit.
Note
Notes provide additional information, useful tips, or
emphasize an important point.

INTRODUCTION
Details of repetitive procedures are listed below. Details
are not repeated each time the procedure is done.
Instead, a reference to the General Note appears in the
text.
Wear eye or face protection to avoid eye injury. Failure
to observe this warning may result in serious personal
injury.
Note 1: Lubricate all designated O-rings with a very thin
film of Christo-Lube™ lubricant (P/N 604070) before they
are installed. Christo-Lube lubricant is compatible with
brass and aluminum. Do not store parts after lubricating
them because Christo-Lube may collect dirt and contaminants.
We cannot over-emphasize how important it is for all
repair personnel to follow maintenance procedures to the
letter when working on MSA SCBA components. Why?
Failure to perform any part of any procedure, or doing
something contrary to the instructions in the maintenance
procedures, could have serious implications.
Note 2: Pipe-sealing tape is used on fittings with tapered
threads. Wrap 1 to 1-1/2 turns of tape in a clockwise
direction (looking into the threaded end of the fitting).
Start at the second thread. Do not put tape on the first
thread. Pieces of tape can break off and reduce air flow.
Apply a thin film of Christo-Lube lubricant to the outer
surface of the tape before threading the part into another
component.
Follow the C.A.R.E. Maintenance Procedures exactly, and
understand that any deviation from the written repair procedures in this C.A.R.E. Maintenance Procedures Binder
is absolutely unacceptable, unless approved by MSA corporate office personnel. Do not deviate from the written
instructions in any way. If you have any doubt about how
to address a repair or maintenance problem, contact MSA
at 1-800-MSA-2222.
Unless specified otherwise, torques are calculated for dry
threads. Applying any lubricant causes additional stress
on the threads when the component is tightened. This
additional stress could cause the threads to fail, causing
possible separation of components. Lubricants, adhesives, and sealants must be used only as stated in this
Binder. Any deviation from the written procedures must be
approved in writing by MSA corporate office personnel.
Do not over-tighten parts or you may damage the part
or the fitting threads.
Note 3: All repair procedures assume that the Audi-Larm
assembly is disconnected from the apparatus cylinder.
These procedures are intended for use with SCBA manufactured exclusively by MSA.
Be sure to calibrate your torque wrenches, gauges, and
other test instruments regularly. It’s good quality-assurance practice.
Do not use the procedures in this manual for maintaining airline regulators. Airline regulators are designed
for pressures up to 100psig. Their use with an air
source in excess of 100psig may result in airline regulator rupture, causing serious personal injury or death.
Follow torques specified in the detailed procedures in this
Binder. It’s good repair procedure. All torques are listed in
the following sections.
Test gauges and regulator tester are sold separately.
The self-contained breathing apparatus (SCBA), as well as
its dual-purpose breathing apparatus (DPBA) counterpart
from MSA, must be maintained and repaired carefully.
Only trained certified personnel, authorized by MSA, are
permitted to maintain and repair the apparatus, using
replacement parts from MSA only to assure proper performance.
When applying adhesives, keep in mind that more is not
better. Use adhesives sparingly. Although both adhesives
and sealants seal and hold parts in place, never interchange them. Use each adhesive and sealant only where
specified since each has properties uniquely suited to the
designated application.
All O-rings and gaskets which are removed must be
replaced with new ones.
Thorough understanding of all instructions, inspection
procedures, cautions, and warnings which originally
accompanied your breathing apparatus is a prerequisite.
Most repairs can be accomplished with standard tools.
However, certain special tools, tapes, and lubricants from
MSA are required.
When installing O-rings over threads, use transparent
tape, a thin piece of paper, or other thread protector to
avoid damage to the O-ring.

INTRODUCTION
•
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 may cause inhalation or skin absorption
of the contaminant and result in serious personal
injury or death.
The cylinder burst disc vents excess pressure if a full
cylinder is over-exposed to fire or heat. If the cylinder
is not full, it may be damaged before the burst disc
vents.
For maximum safety, cylinders should be stored either full
or empty (pressure above ambient, but less than 100psig).
Note: Check cylinder pressure weekly.
FLOW TEST AND OVERHAUL REQUIREMENTS:
REGULATORS AND AUDIBLE ALARMS
REQUIRED EQUIPMENT AND TOOLS
Note: The MSA apparatus inspecting tag contains a
checklist of the procedures that must be performed after
each use and monthly.
You must have the following equipment to perform the
test and repair procedures this binder:
• A complete SCBA or DPBA
• A fully-charged cylinder
• The PosiChek3
CYLINDERS
SPECIAL TOOLS
Breathing apparatus cylinders should be recharged as
soon as possible after use. Cylinders should not be stored
partially charged for two reasons:
• If used without recharge, the service time of the apparatus is reduced.
Special tools are devices MSA manufactures or has manufactured to its specifications for use in maintaining and
repairing MSA equipment. They are available only from
FLOW TEST AND OVERHAUL REQUIREMENTS
The Second Stage Regulator, First Stage Regulator and Audi-Larm Audible Alarm must be flow tested and overhauled at
the intervals determined by use. MSA air masks must be flow tested annually using an MSA-approved flow test device.
