Step Three: Drain any preservative oil from the engine and replace the drain plug. Fill with a proper grade of lubricating oil. Fill the fuel tank with proper grade Diesel fuel.
Step Four: With all of the drain cocks closed, fill unit with soft water or soft water with anti-freeze, depending on whether you live in a colder area.
Step Five: Install the battery
Step Six: Blow out any dust or debris from the air intake, and make sure that it is not wet, to prevent water from mixing with the fuel.
Step Seven: Set the air shut-off valveto the open or reset position. Place circuit breaker to off position. Press the throttle button and turn the throttle control counterclockwise to a position between run and stop.
Step Eight: Press starting switch. Make sure to wait and allow the engine to cool if it did not start within 30 seconds. Do not press the starter switch again while the starter motor is rotating.

Step Two: Clean any dirt or debris from the rocker cover and remove it. Then rotate the crankshaft until the injector follower is completely depressed on the cylinder you are inspecting.
Step Three: Loosen the exhaust valve rocker arm. Place a 0.026 feeler gauge between the end of one valve stem and the rocker arm bridge.
Step Four: Adjust the push rod to get a smooth pull with the feeler gauge.
Step Five: After taking the feeler gauge out, hold the push rod with a 5/16 th inch wrench. Tighten the lock nut with a half inch wrench.
Step Six: Recheck the clearance and adjust if needed.
Step Seven: Start the engine and allow it to get to normal operating temperature, which is between 160 and 185 degrees Fahrenheit. If the clearance is correct, the 0.24 inch gage should pass between the end of one valve stem and the rocker arm bridge.
