IB26 Air Line Test (Restriction Check)

^ From the previous tests it has been determined that cause of the unable to inflate problem is due to a restriction in the air line or compressor assembly. In order to isolate the cause of this problem the following actions are required:

^ Disconnect any one of the air lines that are plugged into the air compressor drier assembly.

NOTE: As long as STAR test button remains in the up HOLD position the air compressor assembly will continue to pump air through the drier assembly.

^ The rate that air is coming out of drier assembly is:
