Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury.

Starting an Electronically Controlled Engine

Note: Do not adjust the engine speed control during start-up. The electronic control module (ECM) will control the engine speed during start-up.

1. Disengage any equipment that is driven by the engine.

2. Turn the keyswitch to the RUN position and check the multi-function lamp.

3. If the lamp flashes once only, the engine can be started normally. If the lamp flashes again, then a fault has been detected. Refer to this Operation and Maintenance Manual, "Diagnostic Flash Code Retrieval" for more information.

4. During cold weather the keyswitch will need to be in the heat position for a time period to allow the glow plug operation. Some systems will have a wait to start lamp.

5. The wait to start lamp must be extinguished before starting the engine. Refer to the original equipment manufacture for information on how to start an engine in cold weather.

   Note: The ambient weather condition will determine the amount of time the glow plugs will require. If the engine is warm, heat from the glow plugs will not be required to start the engine.

6. Turn the engine start switch to the HEAT position. Hold the engine start switch in the HEAT position for time shown in illustration 1.
