Cooling System
Never add coolant to an overheated engine; allow the engine to cool first.Check the specific gravity of the antifreeze coolant solution frequently in cold weather to ensure adequate protection.If the machine is to be stored in, or shipped to, an area with below freezing temperatures; the cooling system must be protected against freezing to the lowest expected outside temperature.All water is corrosive at engine operating temperature. The cooling system should be protected with conditioner at all times regardless of the concentration of antifreeze. This can be done by using Caterpillar coolant conditioner elements. Use a precharge element when filling the system or changing coolant. Install a new maintenance element every 250 service hours during operation.Do not use Caterpillar coolant conditioner elements with Dowtherm 209 Full-Fill coolant. Follow the instructions provided with the Dowtherm 209 Full-Fill coolant.
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 permanent-type antifreeze.Operate with a thermostat in the cooling system year-round. Overheating will occur without a thermostat.Electrical System
When boost starting machine, follow the instructions in the Operation Guide to properly start the machine.When using external electrical source to start machine, turn disconnect switch off and remove key before attaching booster cables.This machine has a 24 Volt starting system. Use only equal voltage for boost starting. Use of welder or higher voltage will damage electrical system.
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.
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
