WARNING

DO NOT disconnect any air lines or fittings unless engine is shut down and air system pressure is relieved.

Failure to follow this warning could result in serious injury to personnel.

NOTE

Air system lines and fittings are color-coded for ease in matching proper diameter air line with a spe-

cific fitting. Each of various air line diameters is represented by a different color.

When replacing an air line, always replace with the same size, to ensure proper performance. Check

carefully for restrictions such as kinking or bending, and ensure that air lines are properly supported.

Some air lines use conventional compression fittings with tube nuts. Other air lines use plastic push-in

fittings. The following General Replacement Procedures apply to both type fittings.

GENERAL REPLACEMENT PROCEDURES

If replacing more than one air line at a time, tag lines to ensure correct installation.

NOTE

As required, to gain access to air lines routed into front of cab, remove front access panel (WP 0046 00).

Disconnect air line from component at each end of air line. Refer to Push-In Fitting Removal below for instructions on

disconnecting air lines and removing fittings that have push-in type fitting ends.
