Fuel System
Fill the fuel tank at the end of each day of operation to drive out moist air and to prevent condensation. Do not fill the tank to the top. Fuel expands as it gets warm and may overflow.Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to the fuel system parts.
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 the precleaner screen daily for accumulation of dust and debris.Remove any dust and debris as needed. If the indicator 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
The machine is equipped with a diagnostic connector, shown above, for use in preventive maintenance and test analysis of the starting and charging circuits.A 6V2150 Starting/Charging Analyzer Group is available from your Caterpillar dealer.The 6V2150 Group is a diagnostic tool that mates with the diagnostic connector on the machine. This connector locates all pertinent test points in the starting and charging circuits in one location.This one-man test requires no electrical circuit experience. When the analyzer is plugged into the diagnostic connector, the multi-channel voltmeter lights simply read out a "GO," "NO GO" indication.Consult your Caterpillar dealer for more complete information.Scheduled Oil Sampling (S O S)
Use Scheduled Oil Sampling (S O S) to monitor the condition and maintenance requirements of your equipment. Each
