CLAMP AS 2935488 - Caterpillar

Service the primary filter element only when the alert indicator for the intake air filter is flashing. Do not open the filter compartment unless it is time for service. Opening the filter compartment can cause dirt to get into the clean side of the filter housing.
Extremely short air filter life can result if the precleaner system malfunctions. If air filter life is drastically reduced from typical for the operating conditions, consult your Caterpillar Dealer. The exhaust system dust ejector for the strata tube precleaner must pull a minimum vacuum of 508 mm (20 inch) of water.
Service the engine air filters with the engine stopped. Engine damage could result.
Always leave the secondary filter element in place while you clean the primary element, or while you clean the air cleaner housing.
Do not use the filter for longer than one year.
