Precautions During Use - MSA AirHawk II Mode D'emploi

There must be a continuous flow of air when the
bypass knob is opened. If not, do not use the
apparatus. The respirator must be checked and the
condition corrected by an MSA trained or certified
repairperson before using it. Failure to follow this
warning can result in serious personal injury or death.
Note: If the Air Mask passes all tests, the unit is ready to
use. Remember, you must perform these tests every time
before you enter the hazardous atmosphere. If the unit
fails to meet any of the tests, the condition(s) must be
corrected before using the apparatus.
INSTALLING SLIDE MASK MOUNTED REGULATOR
1. Grasp regulator and orient regulator so that red
bypass knob is pointing to the right and slide button is
on top.
2. Slide regulator onto rail (fast track) of facepiece cover.
Slide regulator down the rail cover until regulator
stops.
3. Insert regulator into facepiece adapter by pushing
inward.
4. Ensure the regulator locks into facepiece.
5. Check proper engagement by pulling on the regulator
to ensure regulator is securely attached to facepiece.
Do not use the respirator unless the regulator is
connected properly. A regulator that is not installed
correctly can separate from the facepiece
unexpectedly. Return the respirator to an MSA trained
or certified repairperson to correct the condition.
Failure to follow this warning can result in serious
personal injury or death.
6. Inhale sharply to start the airflow.
a. Check the bypass again by turning the red knob
counter-clockwise until you feel increased airflow.
Close the bypass.

PRECAUTIONS DURING USE

Periodically check the pressure indicated on the remote
pressure gauge. It continually displays the cylinder
pressure. When the needle reaches the red zone, the
alarm
will begin sounding. When the alarm starts sounding or
when the pressure reaches approximately 25% of the
rated service pressure, return to fresh air.
The alarm activates when cylinder pressure drops below
approximate values:
550 psig approximately for low-pressure
1125 psig approximately for high pressure
when the alarm activates, immediately return to fresh air.
Note: Air mask service life is reduced greatly when the
bypass is used.
•
Reduced air flow:
•
Air mask free-flows: Immediately return to fresh air.
•
Audible alarm
sounds:
9
Immediately open the bypass.
Immediately return to fresh air.
