DONNING
Note: A nosecup accessory is available to reduce lens
fogging. If the respirator will be used in areas of high
humidity or at temperatures below 32°F, the nosecup
accessory may be installed.
DO NOT wear eyeglasses with a full facepiece. The
temples or sidebars on eyeglasses will prevent an air-
tight seal. If you must wear glasses, install the specta-
cle kit. Failure to follow this warning may cause
inhalation of contaminated air resulting in serious per-
sonal injury or death.
DONNING ADVANTAGE 3000(MODEL 3100)
RESPIRATOR WITH ADJUSTABLE RUBBER HARNESS
1. The mask may need to be initially donned more than
once to determine the correct adjustment of top
straps and obtain a proper fit.
2. Verify top straps are evenly located and loosen the
two bottom straps. Grip the straps by inserting
thumbs through the straps. Insert chin well into lower
part of facepiece and pull harness back over head.
3. Push the back of the harness downward toward the
neck until it is centered.
4. If necessary, hold the mask component housing with
one hand and position the harness with other hand until
obtaining a firm and comfortable fit against the face.
5. Tighten the two bottom straps so that the mask is
snug against the face. The top straps should be flat
against the top of the head.
6. If the mask does not feel snug against the face, remove
the mask, adjust the top straps and go to step 2.
To Adjust the Top Straps:
1. Remove the mask. The top straps should be adjusted
with the mask off.
2. Remove the strap from the fastener button, by pulling
the loose end of the strap away from the fastener but-
ton.
3. Move the slide away from the lens ring to allow the
strap to slide through the lens ring connection. Adjust
the length of the strap. Pull the straps to the next
hole. Secure the strap in position by pulling the strap
onto the button.
4. Smooth the straps so that they are flat. Move the
slide so that it is located at the lens ring connection.
DONNING THE RESPIRATOR WITH PLASTIC
ADVANTAGE HARNESS
Note: There are two recommended donning procedures.
Donning Procedure A:
1. Completely loosen the two bottom straps. Spread the
straps of the head harness with both hands and place
chin into the mask. Pull harness over head all the
way, until plastic cradle lies flat on back of head.
2. Tighten neck straps evenly so that the mask is snug
against face.
3. If necessary, adjust the mask and tighten harness by
pulling loop on the back of harness.
Donning Procedure B:
1. Completely loosen the two bottom straps, insert fin-
gers and hold the loop on the back of the harness.
2. Place chin into the mask.
3. Pull harness over head with the loop; pull harness
down to the back of the head, until plastic cradle lies
flat on back of head.
4. Tighten neck straps evenly so that the mask is snug
against your face.
FACEPIECE FIT CHECK
(Face-to-Facepiece Seal)
The Air-Tightness Test must be performed each time the
facepiece is donned. You must know the face-to-face-
piece seal is good
before you enter any hazardous area.
1. Block off the breathing tube with either the palm of
your hand or by placing your thumb over the opening
inside the coupling nut.
2. Breathe in and hold your breath for 10 seconds. If the
seal is good, the facepiece will collapse and remain
collapsed against your face.
3. If the facepiece does not remain collapsed or if you
notice any leakage, re-adjust the straps and test
again. If this does not correct the leak,
do not use the
facepiece.
4. If you cannot get a seal by adjusting the headstraps,
check the facepiece and breathing tube for leaks.
Locate the problem and correct it before using the
respirator.
This respirator may not provide a satisfactory seal
with certain facial characteristics, such as beards or
large sideburns, that prevent direct contact between
the skin and the sealing surface of the facepiece. Do
not use this respirator if such conditions exist. The
face-to-facepiece seal must be tested before each
use. DO NOT USE A FACEPIECE THAT DOES NOT
SEAL. Failure to follow this warning can result in seri-
ous personal injury or death.
