How to Reset Your Oil and Hydro Lights: A Simple Guide

Resetting the oil and hydro lights on machinery is a crucial maintenance task, often needed after changes in hydraulic oil or engine oil as part of routine services. This guide provides a clear, step-by-step approach to reset these indicators, ensuring your machine continues to operate efficiently without unnecessary service interruptions.

Understanding the Reset Process

The reset process is straightforward but requires precision to ensure it is done correctly. For both the oil and hydro light resets, the procedure involves a sequence of key turns and lever manipulations while seated on the machine.

Resetting the Oil Light

To initiate the oil light reset, you must be seated on the machine with the brake engaged. Follow these steps to reset your oil light:

  1. Turn the key to the 'On' position and then back to 'Off'. Repeat this sequence four times.
  2. After the fourth cycle, pull one handle inwards.

Once this is done, the display should indicate a reset, typically showing "100" with a wrench icon. This confirms that the oil light reset has been successful.

Resetting the Hydro Light

Resetting the hydro light involves a similar process, though it requires six cycles of the key switch:

  1. Ensure you are seated with the brake engaged.
  2. Turn the key on and off six times.
  3. On the sixth cycle, pull one handle inward.

Following these steps will reset the hydro light, usually displaying "500" on the screen to indicate the reset is complete.

Practical Tips

  • Ensure Safety: Always make sure the machine is in a stable position and that all safety measures are in place before starting the reset process.
  • Accurate Key Cycles: Be precise with the on-off cycles of the key. Miscounts can lead to unsuccessful resets.
  • Confirmation: Always look for the confirmation signal on the display screen to ensure the reset was successful.


Regular maintenance, including resetting oil and hydro lights, is essential for the longevity and efficient performance of your machinery. By following the straightforward steps outlined above, operators can ensure their equipment operates reliably and continues to perform at its best. Remember, keeping a consistent maintenance schedule not only extends the life of the machine but also prevents costly repairs and downtime. If you have any further questions about these procedures, feel free to reach out to a professional or refer back to your machine’s user manual. Thank you for ensuring the proper care and maintenance of your equipment.
