Starting and running Starting the engine Starting at low temperatures and at high altitudes Take the local environmental requirements into account. Use a fuel heater and engine heater to avoid starting problems and white smoke. For environmental reasons the Scania engine has been developed to be started with a low fuel feed. Using unnecessarily large amounts of fuel when starting the engine always results in emissions of unburnt fuel. 1. Open the fuel cock if fitted. Scania recommends that an engine heater should be used if the engine will be used at temperatures below -10°C or at an altitude of more than 2,000 metres. 2. Disengage the engine. 3. If the engine has a battery master switch:
Switch on the power by means of the battery master switch. A low engine speed and a moderate load on a cold engine limits white smoke, gives better combustion and warms up the engine more quickly than warming it up with no load. 4. Start the engine. If the fuel tank has been run dry or if the engine has not been used for a long time, bleed the fuel system. Avoid running it longer than necessary at idling speed. WARNING! Never use starter gas or similar agents to help start the engine. An explosion may occur in the intake manifold with a risk of personal injury. Only start the engine in a well ventilated area.
When the engine is run in an enclosed space, there must be effective devices to extract exhaust gases and crankcase gases. IMPORTANT! The starter motor must only be cranked twice for 30 seconds at a time. After that, it must rest for at least 5 minutes before the next attempt to start it. OPM 100 en-GB 25 © Scania CV AB 2015, Sweden
