4. Operating Instructions
The DB Electrical 410-48316 Starter operates as an integral part of your vehicle's starting system. Its function is to crank the engine to initiate combustion.
4.1 Normal Operation
- Ensure the vehicle's transmission is in Park (P) or Neutral (N).
- Insert the ignition key and turn it to the 'START' position.
- The starter motor will engage the engine's flywheel, causing the engine to crank.
- Once the engine starts, release the key, and the starter will disengage.
4.2 Important Considerations
- Avoid prolonged cranking (more than 10-15 seconds) to prevent overheating the starter motor. If the engine does not start, wait a few minutes before attempting again.
- Do not attempt to start the engine if it is already running.
