GENERAL

The main engine air cleaner is the only source of air to the main engine. It is the crew's responsibility to ensure

that it is properly maintained to avoid damaging the main engine. Maintenance instructions are given for air intake

screens, air cleaner dust cover, and the filter element.

AIR CLEANER RESTRICTION GAUGE

A restriction gauge (Figure 1, Item 1) is located above each air cleaner. It indicates when the air cleaners are

working properly. As the filter becomes restricted, a yellow sleeve (Figure 1, Item 2) begins to pull up into view.

The air flow restriction is at maximum when the yellow sleeve fully covers the red and locks into place. When this

happens, the filter element must be cleaned or replaced In Accordance With (IAW) this work package. To reset

the gauge, press the bottom of the restriction gauge (Figure 1, Item 1).
