Footnotes:
1 With increased air demand the air dryer cartridge needs to be replaced more often.
2 Use the drain valves to slowly drain all reservoirs to zero psi.
3 Allow the oil/water mixture to fully settle before measuring oil quantity.
4 To counter above normal temperatures at the air dryer inlet, (and resultant oil-vapor passing

upstream in the air system) replace the discharge line with one of a larger diameter and/or
longer length.  This helps reduce the air's temperature.  If sufficient cooling occurs, the oil-
vapor condenses and can be removed by the air dryer.  Discharge line upgrades are not
covered under warranty.  Note: To help prevent discharge line freeze-ups, shorter discharge
line lengths or insulation may be required in cold climates.  (See Bendix Bulletins TCH-08-21
and TCH-08-22, included in Appendix B, for more information.)

5 For certain vehicles/applications, where turbo-charged inlet air is used, a smaller size

compressor may be permissible.

e.g. Double/triple trailer, open

highway coach/RV,  (most)

pick-up & delivery, yard or

terminal jockey, off-highway,

construction, loggers, concrete

mixer, dump truck, fire truck.

e.g. Line haul single trailer

w/o air suspension, air over

hydraulic brakes.

e.g. Line haul single trailer

with air suspension,

school bus.

e.g. City transit bus, refuse,

bulk unloaders, low boys,

urban region coach, central

tire inflation.

Regularly scheduled maintenance is the single most important factor in maintaining the air brake charging system.

Note: Compressor and/or air dryer
upgrades are recommended in cases
where duty cycle is greater than the
normal range (for the examples above).
