Page 24: Safety Precautions
SAFETY PRECAUTIONS SAFETY PRECAUTIONS The following safety precautions must be observed when working on a Detroit Diesel engine: PERSONAL INJURY To avoid injury from accidental engine startup while servicing the engine, disconnect/disable the starting system. All engine installations, especially those within enclosed spaces, should be equipped with an exhaust discharge pipe so that exhaust gases are delivered into the outside air.
Page 25 To avoid personal injury, spray the ﬂuid from the bottom of the valve into an appropriate container. The engine starting ﬂuid used in DDEC Ether Start Systems contains extremely ﬂammable and toxic substances. All information subject to change without notice. Copyright © 2007 DETROIT DIESEL CORPORATION...
Page 26 To avoid injury from ﬂying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure. All information subject to change without notice. Copyright © 2007 DETROIT DIESEL CORPORATION...
Page 27 □ Do not place gas cylinders on their sides, but stand them upright when in use. □ Do not drop, drag, roll, or strike a cylinder forcefully. □ Always close valves completely when ﬁnished welding or cutting.

Page 51: Detecting Internal Fuel Leaks
Used lube oil analysis can identify a potential source of engine trouble before it occurs. A program such as the Detroit Diesel Oil Analysis Program is recommended for monitoring crankcase oil in all engines. One of the most serious conditions used oil analysis can uncover is the presence of excessive fuel in the lube oil which should not exceed 2.5% maximum of oil...
Page 52 Since there is no known fuel leak tester available in the commercial market today, one must be fabricated. Use the following guidelines to help in fabricating: □ Although test fuel can be pressurized by variety of methods, Detroit Diesel recommends an air/fuel accumulator design capable of safely withstanding a minimum pressure of 345 kPa (50 psi).
