or certified repairperson to correct the condition.
Misuse can result in serious injury or death.

lose the bypass.
There must be a continuous flow of air when the
b
ypass knob is opened. If not, do not use the air
mask. The air mask must be checked and the condi-
tion corrected by an MSA trained or certified repair-
person before it can be used. Misuse can result in
serious injury or death.
NOTE: If the air mask passes all tests, it is ready for use.
These tests must be performed every time before entering
a hazardous atmosphere. If the air mask fails to meet any
of the tests, the condition(s) must be corrected before
using the air mask.

NOTE: There are two versions (slide-to-connect and
push-to-connect) of the Firehawk Regulator available for
the FireHawk M7 Air Mask. A slide-to-connect Firehawk
Regulator can be identified by examining the side buttons.

pronged fork protruding from it. If this “fork” is present,
refer to Installing the Slide-To-Connect Firehawk
Regulator section.
1. Grasp the Firehawk Regulator and insert the regulator
into the facepiece by pushing inward. Check proper
engagement by pulling on the regulator to ensure that
the regulator is securely attached to facepiece.
DO NOT use the air mask unless the regulator is con-
nected properly. A regulator that is not installed correct-
ly can separate from the facepiece unexpectedly. Return
the air mask to an MSA trained or certified repairperson
to correct the condition. Misuse can result in serious
injury or death.
2. Inhale sharply to start the airflow.
3. Check the bypass again by turning the red knob
counter-clockwise until increased air flow is felt. Close
the bypass.
There must be a continuous flow of air when the
