OPERATING INSTRUCTIONS FOR A FIRST TIME START NOTICE: NOTICE: Failure to eliminate water-diluted lubricating oil may lead to serious engine damage at startup. Under no circumstances should a starting aid such as ether be used to run the engine until the fuel system is primed. Injector damage will result if this method is used. Lube oil diluted by water cannot provide adequate bearing protection at engine startup. For this reason, Detroit Diesel recommends replacing the engine lubricating oil and filters after extended storage. If an external starting aid is used, the heat generated by the external fuel source will cause the injector tips to be damaged when the fuel cools them.
The injector plunger and bushing can be scored from running without lubrication. Fuel System Checks Fill the tanks with the recommended fuel. Keeping tanks full reduces water condensation and helps keep fuel cool, which is important to engine performance. Full tanks also reduce the chance for microbe (black slime) growth. For fuel recommendations, refer to How to Select Fuel Oil in the HOW-TO SECTION of this guide. Make sure the fuel shutoff valve (if used) is open. NOTICE: Engines equipped with starting devices dependent on compressed air or gas reservoirs should always be primed before initial startup.
Otherwise, reserve pressure can be exhausted and injectors may be damaged from lack of lubrication and cooling. NOTICE: Prolonged use of the starting motor and engine fuel pump to prime the fuel system can result in damage to the starter, fuel pump and injectors. To insure prompt starting and even running, the fuel system must be primed if air has entered the fuel system. Priming is done by connecting a manual or electric priming pump to the secondary fuel filter adaptor. This may cause erratic engine operation due to the amount of air in the lines and filters from the fuel supply tank to the cylinder head 16 All information subject to change without notice.
