0115597 JOHNSON OIL RAG

CONTROLS
1-Tractor engine accelerator pedal.
2-Scraper engine accelerator pedal.
3-Brake control pedal. 4-Accelerator locking lever.3. Lock the accelerator pedals at this engine speed with lever (4) located to the right of the transmission control console. The lever can be released by depressing brake control pedal (3). Starting the Diesel Engine at 60° F. and Above: After positioning the controls correctly, the scraper engine may be started as follows:1. Press hydraulic starting motor control button (2).2. As soon as the engine starts, immediately release the control button.
CONTROL LEVER
1-Governor manual control lever.
CONTROL BUTTON
2-Hydraulic starting motor control button.After the engine starts, move governor manual control lever (1) upward to the low idle engine speed position, until the oil pressure gauge indicates normal oil pressure. (The governor manual control lever will override the scraper engine accelerator pedal.) When the gauge indicates normal oil pressure, the engine should be allowed to run for five minutes with the accelerator at approximately half engine speed position before applying the load. During this period the engine gauges should be observed for proper readings as explained in the topic, GAUGES. Avoid unnecessary accelerating of the engine speed before operating temperatures are obtained.If the diesel engine is thoroughly heated but does not start, see that everything is correctly set for starting. If smoke has been coming from the diesel engine exhaust pipe, fuel has been reaching the cylinders. If no smoke has been evident when the accelerator is in the half engine speed position, check the fuel supply. If the diesel fuel tank is empty, or if the fuel tank valve was closed, it will be necessary to prime the system as outlined under the topic, PRIMING THE FUEL SYSTEM. In case there may be water or dirt in the fuel system, or if the fuel injection equipment is suspected, see the topic, FUEL INJECTION EQUIPMENT. Starting Below 60° F. Using Glow Plugs: After positioning the controls correctly, the scraper engine may be started as follows. See the topic, GLOW PLUGS.1. Move governor manual control lever (1) upward to shut off position. (The governor manual control lever will override the scraper engine accelerator pedal.)
CONTROL LEVER
1-Governor manual control lever.2. Press in hydraulic starting motor control button (2) allowing the hydraulic motor to crank the diesel engine against compression for a few revolutions.This will add heat to the diesel engine before starting it. Actual experience will determine the length of time necessary to crank the diesel engine to warm it sufficiently to assure easy starting. Cold temperatures will require longer periods of cranking against compression before injecting fuel.
CONTROL BUTTON
2-Hydraulic starting motor control button.
HEAT BUTTON
3-Heat button.3. Release the hydraulic starting motor control button and move the governor manual control lever downward to open the fuel injection pumps.4. Press in heat button (3) for the length of time required as indicated in the starting aid chart.5. Press in the control button for the hydraulic starting motor and continue to press the heat button until the diesel engine is started and running smoothly. As soon as the engine starts, immediately release the control button.After the engine starts, move the governor manual control lever (1) upward to the low idle engine speed position until the oil pressure gauge indicates normal oil pressure. When the gauge indicates normal oil pressure, the engine should be allowed to run for five minutes with the accelerator at approximately half engine speed position before applying the load. During this period the engine gauges should be observed for proper readings as explained in the topic, GAUGES. Avoid unnecessary accelerating of the engine speed before operating temperatures are obtained. Do not press the heat button while the engine is warm and running.
