Safety instructions D Only open coolant circuit once the engine has cooled down. Follow the instructions given under “Care and Maintenance” in the Operating Man- ual exactly if it is not possible to avoid opening the coolant circuit with the engine at operating temperature. D Do not tighten or undo pipes and hoses under pressure (lubricating oil circuit, coolant circuit and any downstream hydraulic oil circuits). Danger of injury caused by liquids escaping under pressure! D Do not hold hands under the fuel jet when checking injection nozzles. Do not inhale fuel mist D Always disconnect battery when working on the electrical system D Do not use rapid charger to start the engine.
Rapid charging of bat- teries is only permitted with the positive and negative leads discon- nected! D Disconnect batteries only with the “ignition” turned off D Observe manufacturer’s instructions for handling batteries. Caution: Battery acid is toxic and corrosive. Battery gasses are explosive D Only use suitable measuring instruments to measure voltages ! The minimum input resistance of a measuring instrument should be 10 M W D Only disconnect or connect wiring harness connectors on electronic control units only with the “ignition” turned off !
Disconnect batteries and connect the positive lead to the negative lead such that they are electrically conductive before carrying out any electric welding work. Earth the welding set as close to the weld as possible. Do not route cable of welding apparatus parallel to electric lines on board the ship. Refer to the “Welders’ Code of Practice” for further accident prevention measures. D When carrying out repaint jobs , electronic components may be sub- ject to high temperatures (max. 95 ° C) for only very short periods; a period of up to approx. 2 hours is permissible at a max. temperature of 85 ° C, disconnect batteries 5
