Electric Starting
The diesel engine electric starter can be used successfully at altitudes below 2500 feet in temperatures of 15° F. (-9° C.) or above with the use of ether as a starting aid. Without the use of the ether starting aid attachment, electric starting can be used successfully in temperatures of 32° F. (0° C.) or above. In altitudes above 2500 feet, successful use of electric starting can be expected in temperatures above 25° F. (-4° C.) when ether aids are used and 45° F. (7° C.) without the use of ether aids. In temperatures below 60° F. (16°C.), it is recommended that the glow plugs be used to assist starting. When starting in temperatures below 32° F. (0° C.), it is advisable to use crankcase lubricating oil of a lower viscosity in the engine crankcase to reduce the cranking effort. See the topic, OPERATING STARTING AIDS and STARTING IN COLD WEATHER.The engine must be kept in the best mechanical condition possible, the batteries kept fully charged and all terminals kept clean and tight for satisfactory performance of the starting system. Position Controls for Starting: Before attempting to start the diesel engine the controls should be correctly positioned. See the topic, BEFORE STARTING.1. Normally, the compression release remains in the run position unless it is desired to turn the engine for some purpose other than starting.2. Depress the accelerator (1) until it snaps over the detent to turn on the fuel injection pumps, and on compactors move also the governor hand control to about half engine speed position.
An oil pressure actuated stop inside the governor limits movement of the governor control linkage in a direction to increase engine speed until normal oil pressure is reached to prevent damage from excessive engine speed when starting. Do not attempt to force the governor control linkage past the stop.
Starting the Diesel Engine: After positioning the controls correctly, the diesel engine may be started as follows:1. Move the HEAT-START switch (4) to the START position. If the engine does not start in a few seconds, continue to crank the diesel engine but shut off the fuel supply by lifting the accelerator past the shut off position for about ten seconds to clear the cylinders of raw fuel.If the diesel engine fails to start within thirty seconds, release the switch and wait two minutes to allow the engine starter to cool before using it again.If the electric starter pinion disengages for any reason before the engine starts, release the switch and wait until the electric starter stops rotating and the diesel engine stops "rocking" before again turning the switch to the START position.2. As soon as the engine starts release the HEAT-START switch.3. Refer to the topic, AFTER STARTING, for information about engine warming and gauge readings.Gasoline Starting Engine
The starting engine, if so equipped, may be started by means of the starting engine electric starter or manually.Helpful suggestions for starting the starting engine in cold weather are in the topic, STARTING IN COLD
