Check the fuel level on the level gauge. 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 bowl daily for accumulation of dust and debris.Remove the wingnut cover and bowl to clean as needed. If the air filter light is ON immediately after installing the 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.The air filter light in the cab is ON, 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.
Air Conditioner System (If Equipped)
Even in off-seasons, the air conditioner should be kept ready for operation all the year round.Regardless of the season, operate the air conditioner for a few minutes at least once a week and rotate the compressor: this prevents freon leakage caused by a dry shaft seal on the compressor.Scheduled Oil Sampling (S O S)
Use Scheduled Oil Sampling (S O S) to monitor the condition and maintenance requirements of your equipment. Each oil sample should be taken when the oil is warm and well mixed, to ensure that the sample is representative of the oil in the compartment. When using the drain stream to obtain the oil sample, do not collect the sample from the first or final draining. Consult your Caterpillar dealer for complete information and assistance in establishing a Scheduled Oil Sampling program for your equipment.General
Accumulated grease and oil on a machine is a fire hazard. Remove this debris with steam cleaning or high pressure water, at least every 1000 hours or each time any significant quantity of oil is spilled
