Move all hydraulic controls to the HOLD position before starting the engine. Move the transmission control to NEUTRAL position.
Engage the parking brake switch.
Diesel engine exhaust contains products of combustion. These products can be harmful to your health. Always start the engine and always operate the engine in a well ventilated area. If you are in an enclosed area, vent the exhaust to the outside.
Use the following procedure to start the engine.
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. |
An air inlet heater is installed in the air inlet manifold. The air inlet heater is an electrical device which provides heated inlet air for cold weather starting.
Note: Startability is improved at temperatures below 16°C (60°F) with the air inlet heater. This helps reduce white smoke and misfire during start-up in cold weather.
The operation of the air inlet heater is fully automatic on the 3126B Engine that is installed in the D6N Track-Type Tractor. The Engine ECM controls the inputs according to the prevailing condition.
- Turn the battery disconnect switch to the ON position. The battery disconnect switch is inside the access door that is on the left side of the machine.

NOTICE Do not engage the starting motor when flywheel is turning. Do not start the engine under load.
If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
- Turn the engine start switch key to the ON position. The system performs an automatic self-diagnosis. When you turn on the engine start switch key the test is performed. If the test is complete without any faults, proceed to the next step. If the system detects a fault, check the electrical system. Complete all of the necessary repairs before you start the engine.

- The indicator for the air inlet heater is positioned on the upper digital display window. The indicator for the air inlet heater will come on during the next cycle before engine start-up.
- 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.
- When the indicator light goes off, turn the engine start switch key to the start position in order to start the engine.
- Turn the engine start switch key to the START position. Crank the engine. When the engine starts, release the engine start switch key.

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.
- Allow the engine to idle for three to five minutes, or allow the engine to idle until the water temperature indicator begins to rise. The engine should run at low idle smoothly before increasing to high idle. Allow the white smoke to disperse before proceeding with normal operation.
- Operate the engine at low load until all systems reach operating temperature. Check the gauges during the warm-up period.
