OPERATING INSTRUCTIONS FOR STARTING THE ENGINE Authorized Detroit Diesel service outlets are properly equipped and have the trained technicians to perform this service. Priming the Fuel System Prime the fuel system as follows: 1. If equipped with a hand pump on the fuel filter or fuel/water separator, work the hand pump until resistance is felt. Priming is not normally required if the filter elements are filled with clean fuel when installed and the lines are not drained of fuel. If priming is required refer to section Priming the Fuel System 2. Crank the engine for 30 seconds at a time, but no longer. Before cranking the engine again, wait at least two minutes.
The engine should start within four 30-second attempts. If the engine is equipped with a fuel/water separator, drain off any water that has accumulated. Water in fuel can seriously affect engine performance and may cause engine damage. Detroit Diesel recommends installation of a fuel/water separator wherever water contamination is a concern. Other Checks Make sure the transmission is filled to the proper level with the fluid recommended by the manufacturer. Do not overfill. Adding Fuel — Note the following when adding fuel: Add winter or summer grade fuel according to the season of the year. Work in the cleanest conditions possible. Prevent water from entering the fuel tank.
