Pre-reset Checks

Before resetting your Onan generator, perform these essential pre-reset checks. These checks ensure your generator operates smoothly post-reset. Follow these steps for a hassle-free process.

Inspect Fuel Level

Check the fuel level first. Ensure the fuel tank is at least half full. Low fuel can prevent the generator from starting. Use a fuel gauge to measure accurately.

If the fuel is low, fill it up. Use the recommended fuel type for your Onan generator. This prevents engine damage and ensures optimal performance.

Check Oil Level

Next, check the oil level. Locate the oil dipstick on your generator. Remove the dipstick and wipe it clean with a cloth.

Reinsert the dipstick, then remove it again to check the oil level. Ensure the oil level is between the minimum and maximum marks. If the oil level is low, add the recommended oil type.

Use a funnel to pour the oil. This avoids spills and keeps your generator clean. Check for any oil leaks around the engine area. Address any leaks before proceeding with the reset.

Performing The Reset

Resetting your Onan generator is a straightforward task. This guide will make it simple. Follow these steps carefully. This ensures your generator works properly. Below are the detailed instructions and troubleshooting tips.

Step-by-step Instructions

  1. Turn Off the Generator: Ensure the generator is off. This prevents any accidents.
  2. Disconnect the Battery: Remove the negative cable first. Then remove the positive cable.
  3. Wait for a Few Minutes: Allow the generator to rest. This helps in resetting the internal settings.
  4. Reconnect the Battery: Attach the positive cable first. Then attach the negative cable.
  5. Turn On the Generator: Start the generator. Check if it operates normally.

Troubleshooting Tips

  • Check the Fuel Level: Ensure the tank is not empty.
  • Inspect the Oil Level: Low oil can prevent the generator from starting.
  • Examine the Battery: Make sure the battery is fully charged.
  • Look for Error Codes: Modern generators display error codes. Refer to the manual for solutions.
