Hitachi ZH210 Hybrid Grease System Reset Guide

[MikePhua]

The Hitachi ZH210 is a highly regarded hydraulic excavator widely used in construction and mining sectors. As a powerful machine, it is equipped with a Hybrid Grease System that ensures continuous lubrication for critical components, extending the lifespan of the equipment. However, at times, the hybrid grease system may encounter issues or require a reset. This article provides a detailed guide on how to reset the Hybrid Grease System of the Hitachi ZH210 excavator.
Function and Importance of the Hybrid Grease System
The Hybrid Grease System in the Hitachi ZH210 is an automated lubrication system designed to provide continuous grease supply to essential parts of the machine. It regularly supplies grease to components like bearings, chains, and slides, ensuring they stay well-lubricated during operation. This system reduces friction, helps maintain high operational efficiency, and minimizes the risk of equipment failure.
Over time, the lubrication system may face issues such as grease supply interruptions, sensor malfunctions, or the need for recalibration. In such cases, resetting the grease system is a crucial step to restoring its normal operation.
Common Reasons for Hybrid Grease System Reset

1. Sensor Malfunction: If the system’s sensors fail, the system may stop functioning properly. When sensors malfunction, recalibration or resetting may be necessary to restore normal operation.
   
2. Inadequate Grease Supply: The system may trigger a reset request if it detects insufficient grease supply. Resetting the lubrication system ensures a smooth and continuous grease flow.
   
3. System Alarm: If the machine triggers an alarm indicating a lubrication system fault, a manual reset may be required to clear the error and restart the system.
   

Steps to Reset the Hybrid Grease System

1. Preparation:
   • Ensure the machine is in a safe condition, powered off, and disconnected from any electrical sources.
     
   • Inspect the lubrication system for visible physical damage, such as grease leaks or clogged pipes. If any issues are found, repair or replace the damaged components.
     
2. Access the Control Panel:
   • Open the operator’s panel and navigate to the lubrication system section. This is typically found under the settings or diagnostic menu on the machine’s display.
     
   • Use the touchscreen or buttons to locate the system status options.
     
3. Select the Reset Option:
   • In the control panel, select the reset option, and the system will prompt you to confirm the reset operation.
     
   • Once confirmed, the system will automatically initiate the reset process and restart the lubrication system.
     
4. Check the Lubrication System’s Status:
   • After the reset is completed, verify whether the lubrication system is functioning properly. You can monitor the system’s display for information regarding grease flow to confirm that it is being supplied properly.
     
   • If the system still indicates a fault, further investigation may be required, or you may need to contact a technician for assistance.
     

Common Issues and Solutions

1. System Does Not Respond to Reset Command:
   If the system does not respond, it could be due to insufficient power supply to the machine. Check the battery level or power connections to ensure that the equipment has adequate electrical supply.
   
2. Inadequate Grease Supply:
   If, after resetting, the grease still does not flow properly, it may indicate a fault with the grease pump or a blockage in the supply lines. Inspect the grease pump and piping to ensure there are no clogs or leaks.
   
3. Control Panel Displays a Fault:
   If the control panel still shows fault messages after resetting, verify the wiring and sensors. Sensor failure may affect the reset functionality of the system.
   

Conclusion
The Hybrid Grease System in the Hitachi ZH210 plays a vital role in providing continuous lubrication, extending the machine’s lifespan, and enhancing operational efficiency. When lubrication issues arise, performing a reset is an important method for restoring normal functionality. By following the correct steps, operators can resolve most grease system problems and ensure the machine operates efficiently during work.
