The engines that are listed above may be equipped with disposable paper air filters. Engines that are equipped with a disposable paper air filter must be stored indoors. If the engine is stored outdoors, a suitable plastic bag or covering must be used in order to prevent water contamination of the filter due to rain or other weather related moisture. Water can penetrate the air filter element if no protection is provided. This could lead to damage of the turbocharger or components of the engine.

Refer to Table 1 in order to determine the filters that need to be covered.

Refer to Special Instruction, SEHS9031, "Storage for Caterpillar Products" for more information.
