Starting the Engine
Disengage any equipment that is driven by the engine.
Turn the keyswitch to the RUN position. Leave the keyswitch in the RUN position until the warning light for the glow plugs is extinguished. Note: During the key on, the indicator lamps will be illuminated for 2 seconds in order to check lamp operation. If any of the lamps do not illuminate, check the bulb. If any indicator lamps stay illuminated or flash, refer to Troubleshooting, "Indicator Lamp Circuit - Test".
When the warning light for the glow plugs is extinguished cycle the keyswitch. Turn the keyswitch to the OFF position and then to the START position in order to engage the electric starting motor and crank the engine. Note: The operating period of the warning light for the glow plugs will change due to the temperature of the engine.
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.
Allow the keyswitch to return to the RUN position after the engine starts.
Repeat step 2 through step 4 if the engine fails to start.
After starting, the engine may be held at low speed for a duration between 1 and 25 seconds to allow engine systems to stabilize. The duration will depend on ambient temperature, time since last run and other factors. The glow plug warning light will flash in order to indicate that the engine is been held at low speed.
