1. Add a substantial amount of fuel to the tank, approximately 2 to 5 gal (8L to 19L). 2. Three priming cycles must be completed. Turn ignition to the RUN position and wait approximately 30 seconds. This will activate the in tank fuel pump. Turn the ignition switch to the off position, and leave off for at least 30 seconds. Repeat this procedure three times before cranking the engine. 3. Start the engine using the “Normal Starting” 4. Once the engine starts, allow the engine to idle for a minimum of 30 seconds. NOTE: The engine may run rough until the air is forced from all the fuel lines. NOTE: A maximum blend of 5% biodiesel, meeting ASTM specification D-975 may be used with your Cummins diesel engine. (Chassis Cab models not configured with B20 capability.) A maximum blend of 20% biodiesel, meeting ASTM specification D-7467 may be used with your Cummins diesel engine. (Pickup models and Chassis Cab models configured with B20 capability.) WARNING! Do not open the high pressure fuel system with the engine running. Engine operation causes high fuel pressure. High pressure fuel spray can cause serious injury or death. CAUTION! Do not engage the starter motor for more than 15 seconds at a time. Allow two minutes between the cranking intervals. WARNING! Do not use alcohol or gasoline as a fuel blending agent. They can be unstable under certain conditions and be hazardous or explosive when mixed with diesel fuel. CAUTION! Due to lack of lubricants in alcohol or gasoline, the use of these fuels can cause damage to the fuel system. |
