Walk-Around Inspection
Perform required Daily and other periodic maintenance before starting the engine. Make a walk-around inspection of the installation. It only takes a few minutes to make minor corrections. This can prevent major repairs at a later date.* For maximum service life of your engine, make a thorough inspection before starting the engine. Look for items such as oil or coolant leaks, loose bolts, and trash build-up. Remove trash build-up and have repairs made as needed.* Inspect the radiator hoses for cracks and loose clamps.* Inspect the fan belts and accessory drive belts for cracks, breaks, and other damage.* Inspect the wiring for loose connections and for worn or frayed wires.* Check the fuel supply. Drain water from the water separator (if equipped). Open the fuel supply valve.
All valves in fuel return line must be open before and during engine operation to prevent high fuel pressure. High fuel pressure may cause filter housing failure or other damage.
If the engine has not been run for several weeks, fuel may have drained and allowed air into the filter housing. Also, when fuel filters have been changed, some air space will be left in the housing. In these instances, prime the fuel system. Refer to Priming the Fuel System in this publication for more information.
Diesel engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well-ventilated area and, if in an enclosed area, vent the exhaust to the outside.
* Do not start the engine or move any of the controls if there is a DO NOT OPERATE or similar warning tag attached to the start switch or controls.* The operator must be satisfied that no one will be endangered before starting the engine.* Disconnect the battery charger (if equipped).* Reset any shutoff or alarm components (if equipped): Low Oil Pressure, Overspeed, Air Shutoff.* Check for damaged or missing guards. Repair or replace any damaged or missing guards.
Oil Level Gauge (Dipstick): ENGINE STOPPED side (1), LOW IDLE side (2), ADD mark, and FULL mark.* Check the oil level. The ENGINE STOPPED side of the dipstick is marked to read when the engine is stopped. The LOW IDLE side of the dipstick is marked to read when the engine is at low idle. Maintain the oil level between the ADD and FULL marks.* Check the coolant level. Make sure the engine is cool. Remove the radiator or expansion tank filler cap slowly to relieve any pressure. Maintain the coolant to within 13mm (1/2 inch) of the bottom of the fill pipe.* Observe the air cleaner service indicator (if equipped). Service the air cleaner when the yellow diaphragm enters the red zone, or the red piston locks in the visible position.Starting, Operating and Stopping Engines Equipped with Control Panels
For information regarding the generator control panel used for starting, operating and stopping the engine, refer to Caterpillar SR4B Generators and Control Panels, SEBU6918 or Caterpillar SR4 Generators and Control Panels, SEBU6150. Additional information and programming instructions are provided in the Service Manual for your specific control panel.Glow Plugs
Precombustion Chamber Engines
Never use the glow plugs when the engine is warm and running.
HEAT/START switch: HEAT (1), OFF (2), AND START (3) positions.1. Push the HEAT/START switch and turn the switch to the HEAT position. Maintain the switch in the HEAT position for the appropriate time shown in the Starting Aid Chart.2. Turn the HEAT/START switch to the START position.3. If the engine runs rough after starting, turn the HEAT/START switch to the HEAT position. Maintain the position until the engine runs smoothly. Electric Starting
Startability will be improved at temperatures below 12°C (55°F) by the use of a starting aid. A jacket water (coolant) heater or other means can be used to heat the crankcase oil.
Do not crank the engine for more than 30 seconds. Allow the starter motor to cool for two minutes before cranking again.
If the engine does not start within ten seconds, move the governor control lever to the FUEL OFF position. Crank the engine for another ten seconds to clear the cylinders of unburned fuel.Start the engine using the following procedure:Manual Starting For EPG Engines
If the Engine Control Switch is in the AUTO position, the engine will automatically start when a remote start/stop contact is closed. The engine will operate within a programmed warm-up cycle.1. Perform all prestart checks.2. Open the main electrical circuit breaker.3. Turn the Manual Speed Potentiometer fully counterclockwise. This will allow the engine to run at a low speed. The GSC will allow the engine to be run at rated speed when the oil pressure sensors indicate sufficient pressure for that speed.
Engine Control Switch (ECS), shown at the MAN. START position.4. Depending on your type of starting controls:* turn the starter to START position, or* turn the ECS to the MAN. START position.Industrial Engines
1. Perform all prestart checks.2. Place the transmission in NEUTRAL. Disengage the flywheel clutch (if equipped).3. Move throttle to approximately half engine speed to get the fuel rack to move to the FUEL ON position.4. Depending on your type of starting controls:* turn the battery disconnect switch to the ON position, or* Turn the starter switch to START position, or* Turn the Engine Control Switch (ECS) to the MAN. START position.Release the start switch immediately after the engine starts.5. Reduce speed to low idle. Allow the engine to idle for 3 to 5 minutes, or until the water temperature gauge indicator has begun to rise. The engine should run at low idle smoothly until speed is gradually increased to high idle.6. Allow white smoke to clear up and proceed with normal operation. Do not apply load to the engine or increase engine speed until the oil pressure gauge indicates normal. Oil pressure should raise within 15 seconds after the engine starts.For starting in cold weather, to minimize white smoke: start the engine and allow the engine to idle for 30 seconds. Increase rpm until engine speed reaches 1200 rpm. Then allow the engine to return to
