Footnote 1: Note: Typical air dryer cartridge replacement schedule is every 3 yrs/300K miles for low air use vehicles and every year/100K miles for

high air use vehicles.

Footnote 2: To get an accurate reading for the amount of oil collected during a 30 day period, ask the customer not to drain the air tanks before

returning. (Note that 30-90 days is the recommended air tank drain schedule for vehicles equipped with a Bendix air dryer that are properly

maintained.) If, in cold weather conditions, the 30 day air tank drain schedule is longer than the customer's usual draining interval, the customer

must determine, based on its experience with the vehicle, whether to participate now, or wait for warmer weather. See the cold weather tips in

Bulletins TCH-008-21 and TCH-008-22 (included in Appendix B of the advanced troubleshooting guide).

Note for returning vehicles that are being

retested after a water/cloudy emulsion

mixture was found last time and the air

dryer cartridge replaced: If more than one

oil unit of water or a cloudy emulsion mixture

is found again, stop the BASIC

™

test and

consult the air dryer's Service Data sheet

troubleshooting section.

Note: A confirmed com-

plaint above does NOT mean

that the compressor must be

replaced.

The full BASIC

™

test below

will investigate the facts.
