Brakes, Indicators and Gauges - Test
Check the operation of the Caterpillar Monitoring System. Observe the self test when you start the engine.
The system performs an automatic self test when you turn the engine start switch to the ON position.
The self test verifies that the monitoring panel and the display modules are operating properly.
The internal circuits, the indicators, and the gauges are automatically checked.
The operator must observe whether gauges (1), indicators (2), and displays (3) are operating properly. The self test lasts for approximately three seconds.
During the self test, all alert indicators flash.
The digital display shows the following readouts:
The monitoring panel is then in the normal operating mode.
If the above tests are not correctly completed, the system will not function in the normal operating mode. Consult your Caterpillar dealer for an electrical system check. Any repairs must be made before you start the engine.

Cutting Edges and End Bits - Inspect/Replace
Engine Air Filter Primary Element - Clean/Replace
NOTICE: Caterpillar recommends certified air filter cleaning ser- vices that are available at Caterpillar dealers. The Caterpillar cleaning process uses proven procedures to assure consistent quality and sufficient filter life.
Observe the following guidelines if you attempt to clean the filter element:
Cleaning Primary Air Filter Elements
The primary air filter element can be used up to three times if the element is properly cleaned and properly inspected. When the primary air filter element is cleaned, check for rips or tears in the filter material. The primary air filter element should be replaced at least one time per two year period. This replacement should be performed regardless of the number of cleanings.
NOTICE: Do not clean the air filter elements by bumping or tap- ping. This could damage the seals. Do not use ele- ments with damaged pleats, gaskets, or seals. Dam- aged elements will allow dirt to pass through. Engine damage could result.
Visually inspect the primary air filter elements before cleaning. Inspect the air filter elements for damage to the seal, the gaskets, and the outer cover. Discard any damaged air filter elements.
Pressurized air is the best method to clean primary air filter elements.
Engine Air Filter Secondary Element - Replace
NOTICE: Always replace the secondary element. Do not at- tempt to reuse it by cleaning. Engine damage could result.
Note: Replace the secondary filter element when you service the primary element for the third time. If a clean primary element has been installed and the filter element indicator still enters the red zone, replace the secondary filter element. Also if the exhaust smoke remains black and a clean primary filter element has been installed, replace the secondary filter element.
Note: Replace the secondary filter element when you service the primary element for the third time. If a clean primary element has been installed and the filter element indicator still enters the red zone, replace the secondary filter element. Also if the exhaust smoke remains black and a clean primary filter element has been installed, replace the secondary filter element.
