Take great care if a cock, plug or engine coolant line must be removed from a hot engine. Open the coolant filler cap carefully and slowly to release pressure before removing the cap completely. Avoid opening the filler cap for engine coolant system (freshwater cooled engines) when the engine is still hot. The starter element may cause an explosion in the inlet manifold.
Never use start spray or similar to start the engi- ne. Foreign objects entering the intake ducts can also cause mechanical da- mage. The rota- ting compressor in the turbocharger can cause serious personal injury. Engine with turbocharger: Never start the engine without installing the air cleaner (ACL). Replace decals that have been damaged or painted over. Check that the warning or information decals on the product are always clearly visible. Reinstall all protecti- ve parts removed during service operations be- fore starting the engine. Take precautions to avoid hot surfaces (exhausts, turbochargers, charge air pipes and starter elements etc.) and liquids in supply lines and hoses when the engi- ne is running or has been turned off immediately prior to starting work on it. If working in proximity to a running engine, care- less movements or a dropped tool can result in personal injury. Loose clothing or long hair can fasten in rotating parts and cause serious personal injury. Approaching a running engine is dangerous. Some work (carry- ing out certain adjustments for example) requi- res the engine to be running. Generally, all servicing should be carried out with the engine switched off. Set up a warning notice at the engine control point or helm. Immobilize the engine by turning off the power supply to the engine at the main switch (-swit- ches) and lock it (them) in the OFF position be- fore starting work. Below is a summary of the risks and safety precau- tions you should always observe or carry out when operating or servicing the engine. NOTE!
