Cooling
Never add coolant to an overheated engine; allow engine to cool first. Check specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.When permanent antifreeze and water solutions are used in the cooling system, the solution should be drained and replaced "EVERY 2000 SERVICE HOURS OR 1 YEAR".However, when additions of inhibitor are made to the cooling system "EVERY 500 SERVICE HOURS OR 3 MONTHS", it is not necessary to drain and refill yearly. The antifreeze change period can be extended to 4000 service hours or 2 years.Do not use Caterpillar Corrosion Inhibitor with Dowtherm 209 Coolant.
If machine is to be stored in, or shipped to, an area with below freezing temperatures; the cooling system must either be protected to the lowest expected ambient temperature, or drained completely. The engine cooling system is protected to -20°F (-29°C), with permanent-type antifreeze, when shipped from the factory.Use clean water that is low in scale forming minerals, not softened water. Add Caterpillar Corrosion Inhibitor or equivalent to the water to provide corrosion protection. Follow the recommendations on the container for the quantity required.1 pint (.5 litre) of Caterpillar Cooling System Inhibitor per 4 U.S. gallons (15 litres) of coolant will give the 3% concentration.Whenever draining and refilling cooling system, always recheck the coolant level when the engine reaches normal operating temperature.Filling at over 5 U.S. gallons (19 litres) per minute can cause air pockets in the cooling system.Premix antifreeze solution to provide protection to the lowest expected ambient temperature. Pure undiluted antifreeze will freeze at -10°F (-23°C).Operate with a thermostat in the cooling system all year-round. Cooling system problems can arise without a thermostat.Electrical
When using jumper cables be sure to connect in parallel: POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-). When using external electrical source to start machine, turn disconnect switch off and remove key before attaching jumper cables.
Hydraulic
Make-up oil added to the hydraulic system must mix with the oil already in the tank. Use only petroleum products unless system is equipped for use with special products. Water or air can cause pump failure. If hydraulic oil becomes cloudy, then water or air is entering the system. Drain fluid, retighten hydraulic suction line clamps, purge and refill system. See your Caterpillar dealer for purging instructions.
Fuel
Fill fuel tank at the end of each day of operation to drive out moisture laden air and to prevent condensation. Do not fill the tank to the brim. The fuel expands when it gets warm and may overflow.
Check fuel level with dipstick in filler opening.Water and sediment should be drained from the fuel tank at the start of each shift or after the fuel tank has been filled and allowed to stand for 5 to 10 minutes.Drain fuel tank of moisture and sediment as required by prevailing conditions.After changing fuel filters, always bleed fuel system to remove air bubbles from system.Drain water and sediment from the main fuel storage tank weekly, and before the tank is refilled.
