Information:

Perform the Operation and Maintenance Manual, "Engine Air Cleaner Service Indicator-Inspect" procedure and perform the Operation and Maintenance Manual, "Engine Air Precleaner Check/Clean" procedure (if equipped) before performing the following procedure.
Never run the engine without an air cleaner element installed. Never run the engine with a damaged air cleaner element. Do not use air cleaner elements with damaged pleats, gaskets or seals. Dirt entering the engine causes premature wear and damage to engine components. Air cleaner elements help to prevent airborne debris from entering the air inlet.
Never service the air cleaner element with the engine running since this will allow dirt to enter the engine.
Servicing the Air Cleaner Elements
If the air cleaner element becomes plugged, the air can split the material of the air cleaner element. Unfiltered air will drastically accelerate internal engine wear. Your Caterpillar dealer has the proper air cleaner elements for your application. Consult your Caterpillar dealer for the correct air cleaner element.
Check the precleaner (if equipped) daily for accumulation of dirt and debris. Remove any dirt and debris, as needed.
Operating conditions (dust, dirt and debris) may require more frequent service of the air cleaner element.
The air cleaner element may be cleaned up to six times if the element has been properly cleaned and inspected.
The air cleaner element should be replaced at least one time per year. This replacement should be performed regardless of the number of cleanings.Replace the dirty paper air cleaner elements with clean air cleaner elements. Before installation, the air cleaner elements should be thoroughly checked for tears and/or holes in the filter material. Inspect the gasket or the seal of the air cleaner element for damage. Maintain a supply of suitable air cleaner elements for replacement purposes.Air Cleaners With Dual Elements
An air cleaner with a dual element contains a primary air cleaner element and a secondary air cleaner element. The primary air cleaner element can be used up to six times if the element has been properly cleaned and inspected. The primary air cleaner element should be replaced at least one time per year. This replacement should be performed regardless of the number of cleanings.The secondary air cleaner element is not serviceable or washable. The secondary air cleaner element should be removed and discarded for every three cleanings of the primary air cleaner element. When the engine is operating in environments that are dusty or dirty, air cleaner elements may require more frequent replacement.

The secondary air cleaner element should be removed and discarded for every third cleaning of the primary air cleaner element. Note: Refer to "Cleaning the Primary Air Cleaner Elements".

Clean the inside of the air cleaner cover and body with a clean, dry cl
