DL06 Operation and Maintenance 2.3.20. Turbo charger z The turbocharger needs not any specific maintenance. z Every time of engine replacement, a leakage or clogging of oil pipes should be inspected. z Air cleaner should be maintained carefully for nut or foreign material not to get in. Periodic inspection should be applied on the compressed air and exhaust gas pipes, For leaking air will bring the overheat engine, an immediate repair must be done. z During the operation that is surrounded by the dust and oil mixed air, frequent cleaning must be done on the impellers. Tear down the impeller casing (attention: be careful not to bend) and must clean with non-acid solvent solution.
