Engine Air Cleaner Important: Failure to follow proper filter servicing instructions could result in catastrophic engine damage. The air cleaner assembly consists of an outer (primary) filter element and an inner (secondary) filter element. There is an electrical air filter restriction indicator for monitoring the condition of the elements. If the air filter becomes restricted, this indicator will trigger a lamp light in the left information center electronic display to warn the operator that the air cleaner requires service. For replacement elements, refer to the Replacement Parts chart (page 58). The outer element should be replaced only when the restriction indicator lamp lights. The inner element should be replaced every third time the outer element is replaced, unless the outer element is damaged or the inner element is visibly dirty. Along with a daily check of the restriction indicator, check that the air cleaner intake hose and clamps, and the mounting bracket hardware are properly secured. 4 2
