3-10. MAIN ENGINE AIR CLEANER.
WARNING
NBC contaminated filters must be handled using adequate precautions (refer to FM
21-40) and must be disposed of by trained personnel.
CAUTION
Main engine air cleaner is only source of air to the engine. It is your responsibility
to ensure it is properly maintained to avoid damage to engine. Maintenance
instructions are given for air intake screen, air cleaner dust cover, and filter
element.
a.
Air Intake Screen. Remove dirt or mud restricting airflow through air intake screen (1).
b.
Filter Element Replacement. A restriction indicator (1) is located above each air cleaner. It will read green
when air cleaner is working properly. As filter becomes restricted, a red sleeve (2) appears. When airflow
restriction is maximum, a red sleeve fully covers green and locks into place. When this happens, filter element
must be cleaned or replaced. To reset it, press top of restriction indicator.
