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.
The filter should be kept in service for no longer than one year.
