5.7
Position the chin strap so it fits comfortably under
the chin.
5.8
Position the knit cuff on the inner collar so that it fits
snugly around the neck in turtleneck fashion, without any
interference from clothing such as shirt collars. When
correctly positioned the smaller elastic end of the collar
must face up.
WARNING
Correct placement of the inner collar is critical for
providing the protection for which the respirator
is designed. The collar must be positioned and
maintained without any interference from items
such as hair, facial hair, or shirt collars, between
the collar and user’s neck.
5.9
Pull the cape down to fully extend it and connect
the four elastic straps (two on each side) under the arms,
and tighten using the slides provided.
5.10
Put the belt and Constant-Flow Connector on over
the cape. Buckle the belt around the waist, and tighten it by
pulling the belt end through the buckle insert.
5.11
When finished blasting and with cleanup, remove
the respirator in a clean, non-hazardous environment
where the air is safe to breathe.
WARNING
Do not put the respirator on, or store it in a blast
contaminated environment. Do not remove the
respirator in a contaminated environment except
for emergency evacuation when the use of the
respirator hinders escape.
NOTE: The quick disconnect coupling on the end of the
respirator hose is not equipped with a shut-off. Therefore,
if the hose is disconnected from the respirator while the
pump is in operation, air will continue to flow freely from the
hose. After removing the respirator in a clean environ-
ment, the air pump should be shut off.
