RESPIRATOR ASSEMBLY
ASSEMBLING THE MASK-
MOUNTED RESPIRATOR
1. If necessary,
remove the cou-
pling nut from the
facepiece inhala-
tion housing. The
coupling nut may
be used if the
facepiece is used on MSA respira-
tors. Check that the inhalation check
valve and spider gasket are in the
facepiece inhalation housing. The
gasket is needed so that the face-
piece and motor-blower will seal.
2. Thread the motor-
blower coupling
nut into the face-
piece until resist-
ance is encoun-
tered. Continue
tightening the
coupling nut an additional 60
degrees (the distance of two notch-
es on the coupling nut) into the
facepiece.
3. If attached, unthread the filter from
the motor-blower assembly.
4. Check that there
is a gasket in the
motor-blower
housing. The gas-
ket is necessary
so that the filter
and motor-blower
will seal.
Do not use the respirator if the spi-
der gasket in the facepiece inhala-
tion housing or the gasket in the
motor-blower housing is missing or
appears damaged. Failure to follow
this warning will permit the contami-
nant to be drawn into the respirator
and inhaled, resulting in serious res-
piratory injury or death.
5. Thread the filter
into the motor
blower and hand-
tighten.
6. Line up the key on
the battery cable
plug with the slot
in the female con-
nector on motor-
blower.
7. Push the plug into female connector
and turn to secure.
