1. Place the palm of your hand over the AIR KLIC as
shown in Figure 19.
2. Inhale and hold your breath for a few seconds.
The facepiece should collapse on your face without
leaking.
3. If the facepiece leaks, reposition it, check the
straps, and repeat the leak check.
f. Pressurization
1. Remove the second stage regulator from the waist
strap-mounted regulator holder by pressing the two
release buttons simultaneously.
2. Fully depress the shutoff button on the second
stage regulator.
3. Verify that the red bypass knob is in the closed
position.
4. Fully open the cylinder valve. See Figure 20.
WARNING
In order to fully open the cylinder valve, the
handle must be rotated until it cannot rotate
further. Failure to comply with this warning
may lead to personal injury, illness, or death.
WARNING
Avoid impacts to the second stage regulator
when the cylinder valve is open. This may
inadvertently activate the First-Breath-On
mechanism, causing air to fl ow from the
regulator and depleting the air in the cylinder.
Failure to comply with this warning may lead
to personal injury, illness, or death.
a. Ensure that the needle on the chest-mounted
pressure gauge reads in the green (FULL) zone.
b. Check the Heads-Up Display (HUD) to ensure
that the display reads full cylinder pressure (all
four green LEDs lit).
vi. Perform a leak check as described in section
VI, E, page 14.
NOTE
When properly adjusted, the headnet should
be centered on the back of your head, and the
lower straps should be below your ears.
D. Exhalation Valve Test
WARNING
Do not use this SCBA in a contaminated
atmosphere if the exhalation valve is not
working properly. Failure to verify that the
exhalation valve is functioning properly
could result in diffi culty in exhaling from
the facepiece. Failure to comply with this
warning could lead to personal injury or
death.
1. To test the exhalation valve, take a deep breath
and hold it. Cover the AIR KLIC as shown in Figure
18 and exhale.
2. If the exhalation valve is stuck, it will be diffi cult to
exhale. If the exhalation valve is stuck, exhale sharply
to open the valve. If the valve still does not open,
clean the valve per the instructions in the repair table
in this manual.
E. Leak Check
WARNING
Do not use this SCBA in a contaminated
atmosphere if you do not obtain a satisfactory
seal during the leak check. If a seal was not
obtained, reposition the facepiece, check
the straps, and perform the leak check
again. Failure to obtain a satisfactory seal
could allow contaminants to leak into the
facepiece, causing illness or death.
