4.1 SERVICE LIFE

The service life of this respirator will vary depending on the work environment.
Replace the filter after eight hours of use, or more frequently if used in a dirty
environment or if breathing becomes difficult.
The entire respirator should be replaced when soiled or damaged.
TO TAKE OFF THE RESPIRATOR
Go to an area with uncontaminated breathable air.
Loosen the headbands and remove the facepiece.

TURNAROUND CHECKS

After each use, the respirator should be examined by trained personnel.
Check for worn, damaged or missing parts and replace the entire respirator if
worn, damaged or missing parts are observed.
The respirator facepiece should be wiped with a North 7002 respirator wipe
pad to remove facial oils and loose particulates.
If used for eight hours, the filter should be changed. (See FILTER REPLACE-
MENT).
Do not attempt to repair or disassemble the respirator except to replace
the filter. The respirator is intended to be discarded when it becomes
worn, soiled or damaged. Any other maintenance or substitution of
parts voids the NIOSH Approval and all North Warranties.

FILTER REPLACEMENT

The replacement of the filter must be done in a safe area containing uncon-
taminated breathable air.
