2. Use a light source to inspect the filter elements after
cleaning. Do not use a filter element with damaged
pleats, gaskets, or seals.
NOTE: If the filter element is damaged, have Unit
Maintenance replace the element.
3. Wrap and store the clean filter elements in a clean,
Cab Air System
If nuclear, biological, or chemical (NBC) exposure
is suspected, all filter media should be handled
by personnel wearing protective equipment.
Consult the unit NBC officer or NBC non-
commissioned officer for appropriate handling or
Service Filter Elements
Clean the filter elements when a significant reduction
in air circulation is noticed. Maximum performance can
not be achieved unless the filter is kept clean.
Before servicing the filters, switch off the blower, close
all windows, and forcibly close the door. The resulting
back pressure will dislodge most of the loose dirt from
the outside of the filters.
NOTE: In humid conditions, such as often occurs in
the early morning, do not switch on the blower prior to
servicing the filter. Damp particles drawn into the filter
may be difficult to remove when cleaning.
1. Open access door (1) on the right side of the cab.
2. Open latch (2) at the bottom of the filter bracket
and remove the bracket.
