Axle Breathers - Clean/Replace
Battery - Recycle
Always recycle a battery. Never discard a battery.
Always return used batteries to one of the following locations:
Battery or Battery Cable - Inspect/Replace
Boom Telescoping Cylinder Air- Purge
Boom and Frame - Inspect
Retract the boom and raise the boom away from the main frame and support cradle (1). Support the boom with a suitable stand.
Inspect the complete main frame and the support cradle. Inspect the main frame and the support cradle particularly in welded structures.
Pay particular attention to the mounting points for the following parts:
Circuit Breakers - Test
The circuit breakers are located under the engine hood on the front right side of the engine compartment.
Reset the circuit breaker if the breaker trips. Push in the button in order to reset the circuit. If the button does not remain depressed or the circuit breaker trips soon after being reset, check the appropriate electrical circuit. Repair the electrical circuit, if necessary.
Cooling System Pressure Cap - Clean/Replace
Personal injury can result from hot coolant, steam and alkali.
At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.
Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand.
Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.
The cooling system pressure cap is located on the coolant tank inside the engine compartment.
Engine Air Filter Secondary Element - Replace
NOTICE: The filter should be kept in service no longer than six months or 500 service hours.
Fuel System - Prime
Note: If additional priming is necessary, refer to the appropriate Service Manual for additional information.
Fuel System - Prime
Fuel Tank Cap - Clean
The fuel filler cap is located behind protection cover (3) on the left side of the cab.
Note: Before the machine is refueled or before the fuel filler cap is cleaned, remove foreign material from the top of the fuel tank.
Fuses and Relays - Replace
Oil Filter - Inspect
Use a filter cutter to cut the filter element open. Spread apart the pleats and inspect the element for metal and for other debris. An excessive amount of debris in the filter element can indicate a possible failure.
If metals are found in the filter element, a magnet can be used to differentiate between ferrous metals and nonferrous metals.
Ferrous metals can indicate wear on steel parts and on cast iron parts.
Nonferrous metals can indicate wear on the aluminum parts of the engine such as main bearings, rod bearings, or turbocharger bearings.
Small amounts of debris may be found in the filter element. This could be caused by friction and by normal wear. Consult your Caterpillar dealer in order to arrange for further analysis if an excessive amount of debris is found.
Using an oil filter element that is not recommended by Caterpillar can result in severe engine damage to engine bearings, to the crankshaft, and to other parts. This can result in larger particles in unfiltered oil. The particles could enter the lubricating system and the particles could cause damage.
Parking Brake - Adjust
If the machine moves during the parking brake test, then perform the adjustment procedure again. If you run out of adjustment on the parking brake handle, refer to the appropriate Service Manual.
Radiator Core - Clean
Window Washer Reservoir -Fill
