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. Make sure all gaskets are properly seated.

ASSEMBLY INSTRUCTIONS
See appropriate user instructions for assembly
instructions. (e.g. 3M™ Filters / 3M™ Air supply unit).
FITTING INSTRUCTIONS
Fitting Instructions must be followed each time the product
is worn.
Select most appropriate size from the 3 sizes of the face
piece available (S / M / L).
1. 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. Figure 1.
2. Take a bottom strap in each hand, place the straps at the
back of the neck and hook the straps together. Figure 2.
3. Tighten the top head harness first by pulling on the
ends of the straps to achieve a comfortable and secure fit.
Tighten the bottom straps in a similar manner. (Strap
tension may be decreased by pushing out on the back
side of the buckles) Figure 3.
FIT CHECK
The Negative Pressure Fit Check is recommended when
using the 3M™ 6035 and 6038 or 2000 Series filters,
whereas the Positive Pressure Fit Check is recommended
when using other 3M filters.
1. Perform a Positive Pressure Fit Check.
Place palm of hand over exhalation valve cover and
exhale gently. If the face piece bulges slightly and no air
leaks between the face and the face piece are detected, a
proper fit has been achieved. Figure 4
2. Perform a Negative Pressure Fit Check.
Press your thumbs into the central indentation of the filters
(2000 Series), or press filter cover and filter body together
(6035/6038), inhale gently and hold your breath for ten
seconds
If the face piece collapses slightly a proper fit has been
achieved. If an air leak is detected, reposition the
respirator on the face and / or re-adjust the tension of the
elastic strap to eliminate the leakage. Repeat the above fit
check. For information regarding fit testing procedures,
please contact 3M.
^ If you CANNOT achieve a proper fit DO NOT enter
the hazardous area. See your supervisor.
