TRUNNION 1U3582 - Caterpillar

Cooling System
Never add coolant to an overheated engine; allow the engine to cool first.Measure the specific gravity of antifreeze solution frequently in cold weather to ensure 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.When additions of cooling system conditioner are made Every 500 Service Hours Or 3 Months, the cooling system drain and refill period can be extended to 4000 service hours or 2 years.The cooling system should contain a 3% to 6% concentration of conditioner at all times, regardless of the concentration of antifreeze.If the machine is to be shipped to, or stored in, an area with freezing temperatures, the cooling system must either be protected to the lowest expected outside temperature with antifreeze, or drained completely.Do not use Caterpillar Cooling System Conditioner with Dowtherm 209 coolant.
The engine cooling system is protected to -20°F (-29°C), with permanent-type antifreeze, when shipped from the factory, unless otherwise specified. Pure undiluted antifreeze will freeze at -10°F (-23°C).Use clean water that is low in scale forming minerals-not softened water. Add Caterpillar Cooling System Conditioner, or equivalent, to the coolant to provide corrosion protection.When draining and refilling the cooling system, always measure the coolant level when the engine reaches normal operating temperature.Filling the cooling system at over a 5 gpm (19 liters/min) rate can cause air pockets in the cooling system.When measuring the coolant level, inspect the radiator cap gasket. Replace the gasket if it is damaged.Premix antifreeze solution to provide protection to the lowest expected outside temperature.Operate with a thermostat in the cooling system all year-round. Cooling system problems can arise without a thermostat.Fuel System
Fill the fuel tank at the end of each day of operation to drive out moisture laden air and to prevent condensation.
Measure the fuel level with the dipstick in the filler opening.Water and sediment should be drained from the fuel tank at the start of each shift, or after the tank has been filled and allowed to stand for 5 to 10 minutes.Drain moisture and sediment from the fuel tank as often as required by prevailing conditions.Drain water and sediment from the main fuel storage tank weekly, and before the tank is refilled. This will help prevent water and sediment from being pumped from the tank into the machine fuel tank.After changing fuel filters, always bleed the fuel system.Engine Air Cleaner
Inspect the air cleaner precleaner daily for accumulation of dirt and debris.Service the air cleaner when the red band is visible in the air cleaner indicator.Electrical System
When using an external electrical source for starting, turn the disconnect switch off and remove the key before attaching the cable to the emergency starting receptacle.When using jumper cables, be sure to connect them in parallel: POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-).
Hydraulic System
Make-up hydraulic fluid must mix with fluid in the tank. Use only petroleum products unless the machine is equipped for use with special products.Water or
