REMOVING THE APPARATUS
11. Slip your right arm out of the shoulder pad first, then
remove the harness.
Note:
Be sure to replace the cylinder with a full one.
Complete Inspection and Cleaning and Disinfecting
Procedures outlines in this manual. Ensure complete
apparatus is clean and dry. Ensure that facepiece head
harness straps and harness adjustment straps are fully
extended. Place the complete apparatus in the storage
case or suitable storage location so it can be reached
easily for emergency use. (See storage instructions.)
CHANGING THE CYLINDER
REMOVING THE SHROUD
1. Unsnap the bottom two retaining straps.
2. Extend bottom left side of shroud and remove shroud
from first stage regulator.
3. Slide shroud off the cylinder valve handwheel.
4. Fold shroud over the
top of cylinder, expos-
ing the cylinder fully.
CYLINDER CHANGE OUT
Be careful not to drop cylinder or bump valve knob. An
unsecured cylinder can become an airborne projectile
under its own pressure if the valve is opened even
slightly.
1. Be sure there is no pressure in the system before
replacing a cylinder. Disconnect the coupling nut.
2. Lift over center buckle to loosen the cylinder strap.
3. Slide out the empty cylinder and install one that is fully
charged. Be sure that the adjustable cylinder buckle is
properly adjusted.
4. Slide the fully charged cylinder into the carrier, with
gauge facing out, pull the over center strap and buck-
le to tighten the cylinder strap.
5. To check that the cylinder is secure, place one hand
on the backplate and grasp the cylinder valve with the
other. Try to pull the cylinder and valve down and out
away from the carrier. Make sure that the strap and
buckle hold the cylinder securely in the carrier.
Note:
If the cylinder feels loose, re-check that the strap
and buckle are properly adjusted. Open cylinder buckle.
Tighten cylinder strap by pulling on top (outer) strap. It will
be necessary to reposition the black plastic slide during
adjustment. Tighten cylinder strap until cylinder buckle is
approximately 45 degrees from vertical. Close the cylinder
buckle. Do not use the air mask if the cylinder is not held
securely in the carrier.
Do NOT over-tighten the cylinder strap; otherwise it
will damage the center buckle assembly.
6. Check that the O-ring is inside the coupling nut. If the
O-ring is damaged it must be replaced before the
alarm is used.
7. Thread the coupling nut to the cylinder valve and
hand-tighten (no tools).
RE-ATTACHING THE SHROUD
1. Slide shroud down over cylinder.
2. Slide cylinder valve handwheel through the bottom
slot of shroud.
3. Extend bottom left side of shroud over first stage reg-
ulator.
4. Snap the bottom two retaining straps.
CHARGING CYLINDERS
1. Remove from service if cylinder shows evidence of
exposure to high heat or flame: e.g., paint turned
to a brown or black color, decals charred or miss-
ing, gauge lens melted, or elastomeric materials
distorted.
2. Use this device only after receiving proper training
in its use. Use in accordance with this label and
MSA apparatus instructions.
3. To maintain NIOSH approval, container must be
fully charged with respirable air meeting the
requirements of the Compressed Gas Association
specification G-7.1 1989 for Quality Verification
Level (grade) D air or equivalent specification.
4. Do not use unless the cylinder is filled to the full
pressure approved.
5. Do not alter, modify or substitute any components
without approval of the manufacturer.
6. Inspect frequently. Maintain according to manufac-
turer’s instructions. Repair only by properly trained
personnel.
Failure to comply with these warnings can result in
serious personal injury or death.
