1. Don the support belt. Adjust the motor-blower and fil-

ter assembly to a comfortable position toward your
back.

Do not drop the PAPR. The case can be damaged by
impact. The blower can be loosened or the motor
shaft can be bent. If the unit is dropped, check the
case for cracks. Listen closely to the sound of the
motor. If the blower sticks or rattles, or if air output is
reduced, the entire motor-blower must be returned to
MSA or an authorized MSA Service Center for repair.

2. Check for an O-ring on the end of the breathing tube

coupling nut.

The O-ring must be present to ensure an air-tight seal.
Failure to follow this warning can cause inhalation of
the contaminant, resulting in serious respiratory injury
or death.

3. Thread the breathing tube onto the motor-blower and

hand-tighten the coupling nut.

4. Turn the power switch on. Let air flow through the unit

for a few seconds.

5. Grip the hood and knit collar between your fingers

with both hands. Stretch the collar and pull the hood
down over your head.

6. Put the suspension on your head.
7. Secure the chin strap under your chin.
8. Straighten the knit collar for a good fit around your

neck.

9. Check the hood inlet to make sure it is straight and

not twisted.

Do not wear the hood with the neck seal or bibs under
your clothing. Failure to follow this warning can cause
reduced air flow below the required minimums. This
can reduce or eliminate the protection of the unit,
resulting in serious personal injury or death.
