3176C and 3196 Industrial Engines Starting the Engine Caterpillar

This start procedure may be used for all engines that are not equipped with an Air Inlet Heater regardless of ambient temperature.

Refer to the Owner's Manual of the OEM for your type of controls. Use the following procedure to start the engine.

1. Place the transmission in NEUTRAL. Disengage the flywheel clutch in order to allow the engine to start faster. This also reduces the draining of the battery.

2. Turn the keyswitch to the ON position.

   The "CHECK ENGINE/DIAGNOSTIC" lamp will flash while the engine is cranking. The lamp should turn off after proper engine oil pressure is achieved. If the lamp fails to flash, notify your authorized AVSpare dealer. If the lamp continues to flash, the Electronic Control Module (ECM) has detected a problem in the system. Refer to the Operation and Maintenance Manual, "Diagnostic Flash Code Retrival" (Operation Section) for more information.

3. Push the start button or turn the keyswitch to the START position in order to crank the engine.

   Do not push down or hold the throttle down while the engine is cranked. The system will automatically provide the correct amount of fuel that is needed to start the engine.

4. If the engine fails to start within 30 seconds, release the start button, or the keyswitch. Wait for two minutes in order to allow the starting motor to cool before attempting to start the engine again.

   Note: The "CHECK ENGINE/DIAGNOSTIC" lamp may come on after the engine is started. If this occurs, the ECM has detected a problem with the system. Refer to the Operation and Maintenance Manual, "Diagnostic Flash Code Retrival" (Operation Section) for more information.

   NOTICE
   Oil pressure should rise within 15 seconds after the engine starts. Do not increase engine rpm until the oil pressure gauge indicates normal. If oil pressure is not indicated on the gauge within 15 seconds, DO NOT operate the engine. STOP the engine, investigate and correct the cause.

5. Allow the engine to idle for approximately three minutes. Idle the engine until the water temperature gauge has begun to rise. Check all gauges during the warm-up period.

   Note: Oil pressures and fuel pressures should be in the normal range on the instrument panel. Do not apply a load to the engine or increase engine rpm until the oil pressure gauge indicates at least normal pressure. Inspect the engine for leaks and/or unusual noises.
