CONTROL GP-JOYSTICK 5266695 - Caterpillar

Service the air cleaner only with the engine stopped. Engine damage could result.
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 you Cat dealer.
Service the engine air filter elements only when the alert indicator for the intake air filter is flashing. Do not open the filter compartment unless service is indicated. Opening the filter compartment can cause dirt to get into the clean side of the filter housing.
Do not use the air filter elements for longer than 1 year.
Service the air cleaner filter elements when the engine fault indicator is activated. The engine fault indicator is located inside the cab. The engine fault indicator will activate when there is an inlet air restriction, and the Information Display will provide a message regarding the specific problem. Refer to Operation and Maintenance Manual, "Monitoring System" for further information.Note: Replace the secondary element when you service the primary element for the third time. If a clean primary element has been installed and a warning for the air filter still occurs, replace the secondary element. Also, replace the secondary element if the exhaust smoke remains black after installation of a clean primary element.
