ENGINE AR-CORE 3590425 - Caterpillar

Check the fuel level with the dipstick in the filler opening. Drain the water and sediment from the fuel tank at the start of a shift or after the fuel tank has been filled and allowed to stand for 5 to 10 minutes.After changing the fuel filters, always prime the fuel system to remove air bubbles from the system.Drain water and sediment from any fuel storage tank weekly, and before the tank is refilled. This will help prevent water or sediment being pumped from the storage tank into the machine fuel tank.Use only fuel as recommended in the "Coolant, Fuel and Lubricant Specifications" section of this guide.Hydraulic System
Make-up oil added to the hydraulic tank must mix with the oil already in the system. Use only petroleum products unless the system is equipped for use with special products.If the hydraulic oil becomes cloudy, water or air is entering the system. Water or air in the system will cause pump failure. Drain the fluid, retighten all hydraulic suction line clamps, purge and refill the system. Consult your Caterpillar dealer for purging instructions.
Air Inlet System
Check precleaner (1) daily for accumulation of dust and debris.Remove any dust and debris as needed.If indicator (2) shows red shortly after installing a cleaned primary element, install another clean element, or a new element.The primary element can be cleaned up to six times before replacement. The element, when cleaned, should be thoroughly checked for rips or tears in the filter material. Replace the primary element every year, even though it has not been cleaned six times.The secondary filter element should be replaced at the time the primary filter element is serviced for the third time.If the indicator shows red after installation of a clean primary element, or if the exhaust smoke is black, install a new secondary element.
Do not try to reuse the secondary element by cleaning it. Always use a new element.
Electrical System
When boost starting the machine, follow the instructions in the Operation Guide to properly start the machine.When using an external power source to start the machine, turn the disconnect switch off and remove the key before attaching the booster cables.This machine has a 24 volt starting system. Use only equal voltage for boost starting. Use of a welder or higher voltage will damage the electrical system.
An emergency starting kit is available for starting from an external power source. It provides a permanent receptacle on the machine to plug in a booster cable.Two different cable assemblies are available for auxiliary starting. One for starting from an operating machine (with a receptacle) and one for starting from an auxiliary power pack. Your Caterpillar dealer can provide you with the correct cable assemblies for your operation.Engines installed without engine-to-frame ground straps can be damaged by electrical discharge.To prevent electrical discharge damage, check to make sure the machine's electrical system has an engine-to-frame ground strap. For machines which have the alternator connected to an engine component, the ground strap must connect that component to the frame.Some machines
