Starting
Set the parking brake.
1.
Place the transmission in neutral.
2. Turn the key to the ON position.
3. Wait a minimum of 10 seconds. If the “Wait-to-Start” lamp is still illuminated after 10 seconds,
continue to wait until the lamp is no longer illuminated. The wait to start lamp may stay
illuminated for up to 30 seconds depending on ambient temperature.
4. Start the engine.
5. NOTE: See the Cummins Operation and Maintenance Manual for detailed information on
starting procedures.
Cold-Weather Starting
Turn the ignition switch to the on position. If the Wait-To-Start lamp is illuminated, wait until it goes
out before trying to start the engine. The Wait-To-Start lamp will stay on for up to 30 seconds.
The length of time it remains illuminated depends on the ambient temperature. Once the Wait-To-Start
lamp goes off, turn the key to the start position. If the engine doesn’t start after 30 seconds of cranking,
turn the key to the off position and wait two minutes; then repeat the starting procedure. Once the
engine is started, let it run at idle for 3 to 5 minutes before driving. If normal engine oil pressure doesn’t
show on the gauge within 15 seconds of starting, shut the engine off and contact you nearest Cummins
authorized repair location for assistance.
If the unit is equipped with a block heater, start the block heater 2 to 4 hours before travel.
Engine Braking
Important:
The engine brake is a vehicle slowing device, not a vehicle stopping device. It is not a
substitute for the vehicle service brakes. Use of the engine brake for vehicle downhill control, and
slowing down on level terrain will help the service brakes to remain cool and ready for an emergency.
Engine braking is covered thoroughly in section 3.
