HOSE 1592974 - Caterpillar

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 the fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to the fuel system parts.
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.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 manual.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
If the air filter element is contaminated, not only is the engine output reduced but fuel consumption is increased, leading to detrimental exhaust emisson and black smoke.If the air filter indicator piston moves into the red zone, clean or replace the primary element. The primary element can be cleaned up to four times before replacement. The element, when cleaned, should be thoroughly checked for rips or tears in the filter materials. Replace the primary element every year, even though it has not been cleaned four times.The secondary filter element should be replaced at the time the primary filter element is serviced for the third time.If the piston moves into the red zone or the exhaust smoke is still black immediately after installing a cleaned element, replace the secondary element with a new one.
Do not try to reuse the secondary element by cleaning it. Always use a new element.After servicing the air filter, push the reset button to reset the filter indicator.
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
