The Hitachi EX-100 is a reliable and widely used mini-excavator known for its efficiency and versatility. However, some operators may prefer to switch the machine’s control system to a CAT (Caterpillar) control configuration for reasons such as personal preference or ease of operation. This article provides a detailed guide on how to change the control system on a Hitachi EX-100 to a CAT control system, outlining the necessary steps and key considerations for a successful conversion.
Why Switch to CAT Control?
The decision to switch to a CAT control system often comes down to operator comfort and familiarity. Many operators are accustomed to the smooth, intuitive controls found on CAT equipment. Additionally, CAT controls may offer enhanced precision, better ergonomics, or compatibility with certain attachments and functions. By converting to a CAT control system, operators can standardize their machine experience across various equipment models.
Key Considerations Before Switching
Switching the control system of a Hitachi EX-100 to a CAT configuration is a detailed process that can greatly improve the operator’s experience and machine performance. While the conversion requires expertise and careful planning, it can result in smoother control, enhanced comfort, and better compatibility with other equipment. By following the steps outlined in this article and ensuring proper testing and calibration, you can successfully convert to a CAT control system and improve the efficiency of your machine.

Key Considerations Before Switching
- Compatibility
Before proceeding with the conversion, it’s important to verify that the CAT control system is compatible with the Hitachi EX-100. This includes checking the hydraulic systems, electronic interfaces, and any other components that interact with the control system. Incompatibilities could lead to operational issues or the need for additional modifications.
- Cost of Conversion
Converting to a CAT control system may involve additional costs for parts, labor, and any necessary adjustments to the machine’s hydraulic or electrical systems. Ensure that the costs are justified by the expected benefits in terms of operator performance and comfort.
- Expertise Required
Switching control systems on an excavator is a complex process that requires expertise in hydraulic systems, wiring, and machine operation. It is recommended to consult with a professional technician or service provider with experience in control system conversions to ensure that the work is done properly.
- Disconnect the Battery and Power Down the Machine
Begin by ensuring that the machine is powered off. Disconnect the battery to avoid any electrical hazards during the conversion process. Make sure the area is safe and free of any hazards.
- Remove the Existing Control Components
To switch to the CAT control system, you will need to remove the existing control components, including joysticks, wiring harnesses, and other interface systems. Carefully document the wiring connections and components removed, as you will need to replace them with the new parts.
- Install CAT Control Joysticks and Components
Next, install the CAT control joysticks and associated components. This may include the joystick handles, switches, and any new wiring harnesses required for the system. Make sure that all components are securely fitted and that the wiring is correctly routed to avoid damage or interference.
- Update the Hydraulic Control Valves
The hydraulic system is a critical part of the control system. You may need to replace or adjust the hydraulic control valves to ensure that they are compatible with the new CAT controls. This could involve recalibrating the hydraulic pressure or replacing certain valves to match the new control requirements.
- Integrate the CAT Electronic Control System
The new CAT control system may include an electronic interface for managing functions such as boom, bucket, and arm movements. You will need to connect the new system to the machine’s ECU (electronic control unit) and ensure that the interface is properly configured for all hydraulic functions.
- Test the New Control System
Once the new components are installed, it’s time to test the control system. Power up the machine and check the responsiveness of the new controls. Make sure that all functions operate smoothly, including the movement of the boom, arm, and bucket, as well as any other hydraulic attachments.
- Calibrate the System
After installation, you may need to calibrate the control system to ensure optimal performance. This includes adjusting sensitivity, response time, and precision to match the operator's preferences and the machine’s capabilities.
- Check for Leaks and System Integrity
After the conversion, regularly inspect the hydraulic system and control components for any leaks or issues with system integrity. Ensure that all connections are tight and that there is no loss of hydraulic fluid or pressure.
- Operator Training
If the conversion significantly changes the machine’s operation, it may be necessary to train operators on how to use the new control system effectively. Familiarity with CAT controls can enhance performance and reduce operator fatigue.
- Regular System Checks
As with any conversion, perform regular maintenance checks on the new control system. Monitor its performance and address any issues promptly to prevent wear or malfunction.
