LIFTING GP 1905227 - Caterpillar

Coolant should be drained and replaced "Every 2000 Service Hours or 1 Year." However, when Coolant Conditioner Maintenance Elements are replaced every 250 service hours as recommended, the drain period can be extended to "4000 Service Hours or 2 Years."Premix antifreeze coolant solution to provide protection to the lowest expected outside temperature. Pure undiluted antifreeze will freeze at -23°C (-10°F).Use clean water that is low in scale forming mineral. Do not use softened water.Filling at over 20 liters (5 U.S. gallons) per minute can cause air pockets in the cooling system.After draining and refilling the cooling system, start and operate the engine with the fill cap off until the coolant level stabilizes. Add coolant as necessary to fill the system.When the engine is shipped from the factory, its cooling system is protected to -28°C (-20°F) with a permanent-type antifreeze.Operate with a thermostat in the cooling system year-round. Overheating will occur without a thermostat.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. The 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 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 bleed 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 from 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. Water or air can cause pump failure. If the hydraulic oil becomes cloudy, water or air is entering the system. Drain the fluid, retighten hydraulic suction line clamps, and purge and refill the system. Consult your Caterpillar dealer for purging instructions.
Air Intake System
Check the precleaner screen daily for accumulation of dust and debris. Service the air cleaner when the YELLOW piston in the indicator reaches the RED zone. The indicator is marked in 5 inch of H2O increments to show the amount of air cleaner restriction at any time.The primary filter element can be cleaned up to 6 times before replacement. The element, when cleaned, should be thoroughly checked for rips or tears in the filter material. Replace the primary filter element every year even though it has not been cleaned 6 times.The secondary filter element should be replaced at the time the primary filter element is
