  4. Move the control levers to the HOLD position.


    Illustration 5g00556385

  5. Turn the key start switch to the ON position. The engine oil pressure, and the alternator indicator light on the EMS panel should come on.

  6. Turn the key start switch to START. Crank the engine. Release the key switch when the engine starts.


NOTICE

Do not crank the engine for more than 30 seconds. Allow the starter to cool for two minutes before cranking again. Turbocharger damage can result if the engine rpm is not kept low until the oil gauge display verifies that the oil pressure is sufficient.


Engine Starting with Air Inlet Heater

This machine is equipped with an 3116 AVSpare engine with an automatic electric air inlet heater. The automatic electric air inlet heater is an aid in cold weather starting. The automatic electric air inlet heater also reduces white smoke emissions at start-up. The grid for the air inlet heater is located in the air inlet manifold. The air inlet heater activates automatically whenever the temperature of the engine coolant is 0°C (32°F) or a colder temperature. The heater preheats the air that is mixed with fuel in order to provide proper fuel ignition and improved engine start-up. Heated air in cold temperatures results in the following improvements:

  • Improved starting

  • Less white smoke at start-up

  • Less white smoke after start-up

  • Smoother operation with a cold engine

The air inlet heater is a system that is designed to provide a specified amount of heat. The amount of heat that is provided is based on the following factors:

  • Engine coolant temperature prior to engine start-up

  • Engine coolant temperature during cranking

  • Engine coolant temperature after engine start-up


Illustration 6g00556383

A control in the system activates the grid in the heater when the temperature of the coolant is below the preset value and the ignition switch is turned to the ON position. The indicator lamp on the AVSpare Monitoring System will flash in order to indicate that the air inlet heater is in operation.

------ WARNING! ------

DO NOT USE ETHER (starting fluids) unless specifically instructed to do so. This diesel engine is equipped with an electric air heater system to aid in cold weather starting and to reduce white smoke. DO NOT spray ether into the air intake as it will come in contact with heater element and could result in an explosion or fire. Use ether ONLY if the vehicle is equipped with the optional automatic ether starting aid group or immediate engine damage and personal injury may occur.


Engine Starting Procedure

  1. Turn the battery disconnect switch to the ON position. The switch is located on the right side of the machine in the engine compartment.


    Illustration 8g00556384

  2. Move the transmission direction control lever to the PARK position and then pull the transmission lock lever up to the LOCK position.

  3. Make sure that the governor control lever is in the LOW IDLE position.

  4. Move the control levers to the HOLD position.


    Illustration 11g00556385

  5. Turn the engine start switch key to the ON position. The action light and the alert indicators on the AVSpare Monitoring System should come on.


    Illustration 12g00556383

  6. Observe the indicator light for the air inlet heater. When the indicator light is on, the air inlet heater is in the ON or “preheat cycle”. Do not attempt to start or crank the engine until the light turns off. The indicator light shows that the air inlet heater is in operation. Air is being preheated in order to be used initially for combustion.

  7. Within 5 seconds after the indicator light turns off, turn the key switch to the START position. Crank the engine. The engine should start within 3 and 5 seconds. If the engine does not start within 3 and 5 seconds, continue to crank the engine. While the engine is cranking, quickly move the governor control lever from LOW IDLE to HIGH IDLE, back to LOW IDLE, and then to 1/3 throttle. This will cause the governor to provide additional fuel for start-up. When the engine starts release the key switch.


    NOTICE

    If the engine start key switch is turned to the OFF position before the engine is started, or if the engine does not start, allow the air inlet heater to cool for two minutes before the next attempt to start the engine.

    Do not crank the engine for more than 30 seconds. Allow the starter to cool for two minutes before cranking the engine again. Turbocharger damage can result if the engine speed is not kept low until the engine oil indicator light or the engine oil gauge verifies that there is sufficient oil pressure.


  8. After starting the engine, move the governor control lever to the LOW IDLE position.

    Note: Once the engine starts, the indicator light for the air inlet heater may turn on again. The indicator light may stay on as long as 120 seconds. The engine coolant temperature determines the length of time that the indicator light will remain on. In addition, the air inlet heater is provided with a “post heat cycle”. The “post heat cycle” provides heated air in the intake. The heated air helps maintain good combustion which helps reduce white smoke to a minimum. The heated air also helps the engine idle more smoothly.



    Illustration 13g00556378

  9. If the engine is not idling smoothly, you can push the switch for the air inlet heater in order to provide additional “post heat cycles”. The switch must be pushed within 10 seconds after the indicator light turns off. When the switch is pushed the air inlet heater is turned on for an additional 30 seconds. You can push the switch more than one time in order to maintain a smooth engine idle.

    Your machine may be equipped with an optional ether starting aid. The ether starting aid provides improved startability in severe cold weather at temperatures of −18°C (0°F). Use the ether starting aid ONLY if the normal start procedure fails to start the engine.

    The AVSpare ether starting aid is optional. The ether starting aid can be used in conjunction with the air inlet heater because the ether starting aid sprays fluid downstream from the air inlet heater.


NOTICE

When starting the engine with ether, follow these starting procedure instructions carefully.

Use ether sparingly and spray it ONLY WHILE CRANKING THE ENGINE. Excessive ether use can cause piston and ring damage. Ether should be used only for cold weather starting.


------ WARNING! ------

This machine is equipped with an air inlet heater (AIH) for cold weather starting. Do not use aerosol can types of starting aids such as ether. Such use could result in an explosion and personal injury.




Illustration 14g00556379

If the machine is equipped with an ether starting aid, begin cranking the engine. Push the switch and then release the switch. When the switch is released, a premeasured amount of ether is injected into the air intake. Use only enough ether to start the engine. Ether over use can result in damage to the engine.

Note: An ether starting aid switch is provided on all machines. If you are not sure that your machine is equipped with the ether starting aid, see the Operation and Maintenance Manual, "Ether Starting Aid" in order to determine the location of the ether bottle.

When the temperature is below −23°C (−10°F), see Operation and Maintenance Manual, SEBU5898, "Cold Weather Recommendations" for the recommended engine starting procedure or consult your AVSpare dealer before you operate the machine.
