3) The lengths of the headbands are adjustable;
tighten or loosen by holding the respirator body
or headband yoke with one hand and pulling
on the elastic material in the appropriate
direction with the other hand (See Figure 6).
NOTE
4) Position the facepiece so that the nose section
rests as low on the bridge of the nose as is
comfortable, and tighten the upper headband
on both sides just tight enough so that the
respirator doesn’t slide down on the nose.
Do not over tighten. If the respirator pinches
the nose, loosen the upper headband
slightly (See Figure 7).
5) Then, tighten the lower headband on
both sides just tight enough to secure the
respirator under the chin (See Figure 8).
NOTE
6) If you previously removed your eyewear,
put it back on at this time.
For a proper positioning and com-
fort, the upper headband must
be adjusted first, then the lower
headband must be adjusted.
For a comfortable fit, the head-
bands must be adjusted equally
on both sides of the respirator.
