down and non-drop down

LEVER REPLACEMENT
For removal or attachment of the lever, the catch on the lever must line

MAINTENANCE
This respirator must be kept in good condition to function properly. When a respirator
shows evidence of excessive wear or damage, it must be replaced immediately. (See
PREPARATIONS FOR USE for proper inspection procedures.) Store the respirator in a
clean, dry location. Do not distort the facepiece rubber during storage. Dispose of the
respirator or its components, in accordance with local, state, and federal regulations.
CLEANING AND DISINFECTING
Remove and discard cartridges before cleaning the facepiece. Clean and disinfect after every
use with MSA non-sudsing Confidence Plus® Cleaner (P/N 10009971). Rinse thoroughly in
plain warm water (never exceed 110ºF to avoid overheating and distortion of parts) and then
air dry. ANSI suggests that users should be trained in cleaning procedure.

of the strap through the back of the buckle. Gently pull the loose end.
3. Verify proper installation by connecting the buckles
as-worn
(See

twisted, remove the buckle, untwist it, and reattach the buckle.
