•±
Remove all necklaces and chains. Unbutton your shirt collar if it interferes with the hood
sealing around your neck.
•±
Remove the M52 from its pouch and remove its outer bag by tearing at the notch.
•±
Open the inner vacuum bag at its tear notch and remove the M52. If the protective
padding sticks to the front of the Flter housing, pull it off and throw it away.
•±
Unfold the hood so that the
black rubber neck dam and
nose cup are facing you. The
nose cup should slip into the
hood. If it doesn’t, push it
into the hood. If the nose cup
remains folded, unfold it to its
correct position.
•±
Turn the visor toward you,
placing the rubber neck dam
under your chin. Then pull the
neck dam up and over your
head in a single fluid motion.
•±
Push
long
hair
under
the
neck dam and away from the
sealing surface. Hold the front
of the Flter with one hand and
position the bottom of the nose
cup as low as possible under
your chin. Make sure the top of
the nose cup is positioned on
the bridge of your nose. If you
wear glasses, position the nose
cup just below them.
•±
Hold the Flter and smooth the top of the hood across the top of your head. Position the
visor close to your eyes to give the best possible view.
•±
Squeeze the hood with both hands so that the nose cup is moved slightly away from your
face. This removes excess air trapped inside the hood. You may need to do this several
times to get rid of as much of the air as possible.
•±
Adjust the strap tension so the
nose cup is snug on your face.
Hold the Flter with your left
hand while pulling the right-hand
strap straight back to tighten
the strap. Do the opposite to
tighten
the
left-hand
strap.
If you need to loosen the straps,
pull forward on the backside of
the buckles. If the nose cup is
uncomfortable or collapses on
your face, the straps are too tight.
•±
Shake your head gently side-to-side. If the nose cup moves out of place, tighten the straps.
If the hood inflates and deflates when you breathe, you need to reposition the nose
cup and tighten the straps.

Later…
if you’re not careful when
you put on the M52 mask,
the inside flap of the nose
cup can stick to itself.
That lets carbon
dioxide build up
inside the mask and
you get very
dizzy.
Here’s the
correct
way
to put on
the mask and
avoid the
