1. Don the facepiece properly (see donning procedures under USE
OF THE RESPIRATOR) or hold the facepiece tightly to the face
to effect a good seal. Inhale slightly and hold breath. A negative
pressure (suction) shall be created, pulling the facepiece toward
the face. Hold breath for 5 to 10 seconds. If leakage is noted,
remove the respirator from service and tag for repair by authorized
personnel.
2. Briefly remove the facepiece (see doffing procedures under TERMI-
NATION OF USE) to take a breath if necessary. Don the facepiece
or hold the facepiece tightly to the face. Depress the air-saver/
donning switch fully and release. Open the cylinder valve by turn-
ing the valve knob counterclockwise fully. The VIBRALERT will
actuate and the ELECTRONIC alarm will flash for approximately
five seconds to initialize. No air flow shall be detected at this time.
Inhale sharply to start the flow of air, then take one breath and
hold.
noTe
IF THE PURGE VALVE IS ADJUSTED TO PRODUCE A FLOW, IT
MAY NOT BE POSSIBLE TO RESET THE AIR-SAVER/DONNING
SWITCH BY INHALING; CLOSE THE PURGE VALVE AND REPEAT
THE TEST.
Air shall flow freely into the facepiece during inhalation and stop
when inhalation ceases. VIBRALERT shall actuate. Hold breath for
5 to 10 seconds. If airflow continues after inhalation has ceased,
recheck the fit of the facepiece (see Step 1). If airflow continues
after checking the fit, remove the respirator from service and tag
for repair by authorized personnel. Exhale into the facepiece and
take a second breath. Air shall leave the facepiece through the
exhalation valve during exhalation and fresh air shall flow into the
facepiece on inhalation. Depress the air saver switch fully and re-
lease. Doff the facepiece. No air shall flow from the facepiece.
3. With the cylinder valve open and the air-saver/donning switch
depressed, check the open end of the fitting on the airline con-
nection hose for any sign of leakage. If leakage or if airflow from
the airline connection hose can be detected from the fitting, DO
NOT USE THE Respirator; remove the respirator from service and
tag for repair by authorized personnel.
On respirators equipped with a dual airline connection hose, check
both plugs for leakage. If leakage or airflow can be detected from
the fitting, DO NOT USE THE RESPIRATOR; remove the respira-
tor from service and tag for repair by authorized personnel.
Close the cylinder valve by pushing in on the cylinder valve knob
while turning it fully clockwise. Vent any trapped air in the respi-
rator by opening the purge valve momentarily. Close the purge
valve when air flow and VIBRALERT stop. The ELECTRONIC
alarm shall flash until air is purged from the system. Check the
gauge on the air cylinder to be certain the cylinder still indicates
“FULL.”
