Operation & Maintenance Manual
Charge Air Cooler Pipework
Foreign particles can damage the engine and turbocharger. Maintain internal cleanliness and
integrity of the air filtration, intake piping, and charge air cooler piping to help avoid damage.
Regularly inspect systems for leaks and verify hoses, clamps, and connections are sealed.
Check for damaged or deteriorated components. Pay careful attention to keep the internal
surfaces clean, particularly when parts are removed for inspection or service.
Hoses
All components of the fuel, engine cooling, and air intake system should be checked
periodically to keep the engine at peak efficiency.
At the recommended intervals, (see the Maintenance Schedule), inspect all of the intake lines
to the air filter and all flexible hoses used for air lines, oil lines, and fuel lines.
Periodically inspect all pipework for cracks, leaks, etc. and replace immediately if damaged.
Electrical System
Disconnect the battery cables before performing any maintenance or
service.
Check the security of electrical devices and sensors to ensure terminals and/or connectors are
tight. Loose connections may cause local hot spot oxidation.
When removing connectors from electrical devices and sensors, inspect the terminals to
ensure they have electrical grease on them. If electrical grease is not present or very minimal,
then add a small amount of Doosan Part No. 22409114 electrical grease to the terminals.
Dirty and/or corroded electrical terminals can be cleaned using electrical contact cleaner.
Inspect the components and wiring for signs of overheating (i.e. discoloration, charring of
cables, deformation of parts, acrid smells, and blistered paint).
Battery
Keep the battery terminals and cable clamps clean and lightly coated with petroleum jelly to
prevent corrosion. The battery restraint should be kept tight enough to prevent the battery from
moving.
