cylinder valve fully.
8. Check for air leaks. Open cylinder valve fully to
pressurize system, then close the cylinder valve and

there is a leak. Do not use the apparatus until the leak
is found and corrected.

until gauge needle drops below:
550 psig - approximately (low-pressure system) or,
1125 psig – approximately (high-pressure system)
The alarm will sound. The alarm must continue to
sound until pressure is less than 200 psig. Close the

The air mask must be checked and corrected for
proper operation by an MSA trained or certified
repairperson before using. Failure to follow this
warning may result 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.

temples or sidebars on eye glasses will prevent an
airtight seal. if you must wear glasses, install the
spectacle kit. Failure to follow this warning can cause
inhalation of contaminated air, resulting in serious
respiratory injury or death.
When using the Advantage 4000 Facepiece, ensure the
inhalation valve disc is laying flat against the adapter
orifice.

straps (if necessary) for best visibility and fit. Tuck in
the ends of the straps so they lie flat across the head.
