Notice: If a vehicle does not start on the first attempt, make sure that the engine has completely stopped rotating before reapplying the starter switch. Failure to do so can cause the pinion to release and re-engage, which could cause ring gear and starter pinion damage.
Moving a vehicle with the starter and/or using the starter to bump the engine for maintenance procedures is strictly prohibited. Use of these methods to bump the engine over or move the vehicle can cause the pinion to release and re-engage, which could cause ring gear and starter pinion damage.
Notice: Never attempt to start any Cummins IS series electronic engine (ISB, ISC, ISL) using ether or any other starting fluid. Serious engine damage could result.
- Set the parking brake.
- Turn the ignition switch to the ON position.The low air pressure and low oil pressure warning lights (or messages) and buzzer operate until the engine is started and pressure is built up.The amber wait to start indicator illuminates with the ignition switch in the ON position prior to engine start-up. To avoid generating a system fault code, do not crank the engine until the wait to start indicator goes out.
- Make sure that the transmission shift control is in Neutral (N), or if so equipped, the Park (P) or Park Brake (PB) position.
- Turn the ignition switch to the START position. After the engine starts, release the key.
- Bring the engine up to operating speed gradually as it warms up and develops stable oil pressure.
Warning: Never start the engine unless the parking brake is applied. Accidental movement of the vehicle could result in property damage, personal injury, or death.
Important: Do not depress the throttle pedal while starting the engine.
Notice: Do not crank the engine for more than 30 seconds at a time. Wait two minutes after each try to allow the starter to cool. Failure to do so could cause starter damage.
