PREPARATION FOR USE
UNPACKING
Check apparatus is complete, undamaged and correctly
assembled
Inspection
The following inspection procedure is recommended before
use:
1. Check the face piece for cracks, tears and dirt. Be certain
the face piece, especially the face seal area, is not distorted.
The material must be pliable – not stiff.
2. Examine the inhalation valves for cracks or tears. Lift
valves and inspect valve seat for dirt or cracks.
3. Ensure that the head straps are intact and have good
elasticity.
4. Examine all plastic parts for signs of cracks or fatigue.
5. Remove the exhalation valve cover and examine the
exhalation valve and valve seat for signs of dirt, distortion,
cracks or tears. Replace the exhalation valve cover.
6. Examine filter sealing area (Figure 1) for distortion or
dirt/particulate that could prevent filters from sealing to the
respirator.
7. If present, ensure the speaking diaphragm is securely
inserted in the facepiece and the speaking diaphragm film is
intact.
ASSEMBLY INSTRUCTIONS
See appropriate user instructions for assembly instructions
(eg. 3M filter leaflet)
FITTING INSTRUCTIONS
1. Adjust head cradle size as needed to fit comfortably on
head.
2. Place the respirator over the nose and mouth, fitting it
comfortably on the bridge of the nose, then pull the head
harness over the crown of the head. See Fig. 2.
3. Take a bottom strap in each hand, place the straps at the
back of the neck and hook the straps together. See Fig. 3.
4. Pull the ends of the straps to adjust the tightness,
beginning with the adjustment points on the head cradle and
then moving to the adjustment points at the back of the neck.
Do not over-tighten to the point where the faceseal becomes
deformed. Head Harness/neck strap tension may be
decreased by squeezing the buckle tabs on the harness.
5. Perform a positive and/or negative pressure user seal
check each time the respirator is donned.
Seal Check
Negative Pressure User Seal Check
Lightly press the seal check button and inhale gently (Figure
4). If you feel the facepiece collapse slightly and pull closer to
your face with no leaks between the face and facepiece, a
proper seal has been obtained.
If faceseal air leakage is detected, reposition respirator on
face and/or readjust tension of straps to eliminate air leakage.
Repeat the user seal check until a proper seal is obtained.
Positive Pressure User Seal Check
Cover the opening in exhalation valve cover with hand and
exhale gently (Figure 5). If facepiece bulges slightly and no
air leaks are detected between your face and facepiece, a
proper seal has been obtained.
If faceseal air leakage is detected, reposition respirator on
face and/or readjust tension of straps to eliminate air leakage.
