MSA SAFETY REGULATIONS
AutoMaXX - series 5
1. Safety regulations
1.1. Correct use
The AutoMaXX is a lung governed demand valve for a compressed air breathing
apparatus or compressed airline breathing apparatus. It is connected between
compressed air supply and full face mask and controls the inhaled and
exhaled air.
The lung governed demand valve series are only permitted for specific system
components (exact allocation Chap. 6).
Warning!
The AutoMaXX is not an independent breathing apparatus. It must be
used exclusively mounted on a full face mask.
The AutoMaXX is not suitable for underwater diving.
It is imperative that this operating manual be read and observed when using the
AutoMaXX. In particular, the safety instructions, as well as the information for the
use and operation of the apparatus, must be carefully read and observed.
Furthermore, the national regulations applicable in the user's country must be
taken into account for a safe use.
Alternative use, or use outside these specifications will be considered as non-
compliance. This also applies especially to unauthorised alterations to the
apparatus and to commissioning work that has not been carried out by MSA or
authorised persons.
Danger!
This product supports life and health. Inappropriate use, maintenance
or servicing may affect the function of the device and thereby
seriously compromise the user’s life.
Before use, the product operability must be verified. The product must
not be used, if the function test is unsuccessful, it is damaged, a
competent servicing/maintenance has not been made, genuine MSA
spare parts have not been used.
1.2. Liability information
MSA accepts no liability in cases where the product has been used
inappropriately or not as intended. The selection and use of the product are the
exclusive responsibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect
to the product are voided, if it is not used, serviced or maintained in accordance
with the instructions in this manual.

OPERATION
MSA
10 AutoMaXX - series
3. Operation
3.1. Preparing the device
Warning!
The lung governed demand valve may only be put into use in a fully
maintained and tested condition. If malfunctions or defects are noticed
prior to use, do not use the lung governed demand valve under any
circumstances.
Get the apparatus checked and repaired by an authorised service
centre.
Switching off the device (only Positive pressure lung governed demand
valve)
Before connecting the device to medium pressure, in order to prevent accidental
air delivery, push the red operating button to switch off the AutoMaXX.
For AutoMaXX-AS / AutoMaXX-AS-C:
If a handwheel / connection adapter is provided, ensure that it is
screwed into the mask so that the AutoMaXX can be plugged in.
3.2. Connecting the AutoMaXX
(1) Insert plug-in nipple of AutoMaXX into the coupling of the medium pressure
line until it distinctly snaps into place.
(2) Don full face mask and perform tightness check (palm test)
(Mask operating manual).
(3) Open cylinder valve(s) fully.
(4) Screw AutoMaXX into the mask (AutoMaXX-AE, AutoMaXX-N) or insert it
into the adapter of the mask until it distinctly snaps into place
(AutoMaXX-AS).
Support during donning
The AutoMaXX must be attached to the mask and inspected by a second person.
3.3. Putting the AutoMaXX into operation (only Positive pressure lung
governed demand valve)
To activate, inhale once forcefully or push flush button.
Warning!
When using the flush button or bypass, the compressed air
consumption increases.

AutoMaXX - series 11
3.4. Switching off the AutoMaXX (only positive pressure lung governed
demand valve)
To switch off, push operating button until stopper.
3.5. Removing the AutoMaXX
For AutoMaXX-AE and AutoMaXX-N:
(1) Switch off AutoMaXX-AE by pushing the red operating button.
(2) Unscrew handwheel and separate AutoMaXX from the mask.
(3) Uncouple medium pressure line:
Push the plug-in nipple into the coupling of the medium pressure line
forcefully and pull back the coupling sleeve at the same time.
For AutoMaXX-AS and AutoMaXX-AS-C:
(1) Press both operating buttons simultaneously and separate AutoMaXX from
the mask.
Alternative for AutoMaXX-AS-C: Unscrew handwheel.
(2) Remove medium pressure line:
Push the plug-in nipple into the coupling of the medium pressure line
forcefully and pull back the coupling sleeve at the same time.
3.6. Bypass system (only for AutoMaXX-AS)
A bypass system is available for the AutoMaXX-AS.
It is a safety system that supplies the user with continuously flowing air
independent of the lung governed demand valve. By turning the red handwheel,
the bypass is opened and can be set individually.
Warning!
When using the bypass, the compressed air consumption increases.
3.7. Additional function
Warning!
When using the flush button, the compressed air consumption
increases.
To flush out smoke and gases from the mask, push the flush button.
