Proper throttle calibration is essential for ensuring the efficient performance of the Hitachi EX 60-2 excavator. A miscalibrated throttle can lead to various operational issues, such as poor engine performance, sluggish response, and unoptimized fuel consumption. This guide will walk through the process of diagnosing and calibrating the throttle on the Hitachi EX 60-2, as well as troubleshooting common issues related to the throttle system.
Why Throttle Calibration Matters
Throttle calibration ensures that the engine speed corresponds accurately to the operator’s input, allowing for smooth acceleration and deceleration. In excavators, precise throttle control is vital for operating heavy machinery efficiently, providing the necessary power without overloading the engine. If the throttle is not calibrated properly, the machine may experience:

• Unresponsive throttle: The engine might not rev up when the throttle is increased or decrease too abruptly.
  
• Erratic engine speed: The engine might fluctuate in speed, leading to unpredictable operation.
  
• Increased fuel consumption: Improper throttle calibration can result in the engine using more fuel than necessary, reducing efficiency.
  

1. Slow Response: When you press the accelerator pedal or increase the throttle, the engine takes time to react, or there’s no increase in RPM.
   
2. Uneven RPM: The engine speed fluctuates or doesn’t maintain a steady RPM, even when the throttle is kept at a constant position.
   
3. Inconsistent Power: The excavator may struggle to maintain power or acceleration during heavy tasks, such as lifting or digging.
   
4. Error Codes: Modern excavators, including the Hitachi EX 60-2, often display error codes related to throttle malfunctions, which can indicate calibration issues.
   

1. Turn Off the Machine: Before working on any part of the throttle system, ensure the excavator is powered down and the key is removed to prevent accidental engagement.
   
2. Locate the Throttle Position Sensor: The throttle position sensor (TPS) is the component that communicates the throttle input to the engine control unit (ECU). On the Hitachi EX 60-2, it’s usually located near the throttle pedal or the throttle body. Ensure the sensor is clean and free from debris or damage.
   
3. Check for Loose Connections: Inspect all wiring and connections leading to the throttle position sensor. Loose or corroded connections can cause faulty throttle readings, leading to incorrect calibration.
   
4. Use the Diagnostic Tool: Many modern machines, including the Hitachi EX 60-2, allow for throttle calibration through a diagnostic tool or software. Connect the diagnostic tool to the machine’s diagnostic port and follow the on-screen prompts to perform the throttle calibration procedure.
   
5. Calibration Procedure: Using the diagnostic tool, enter the throttle calibration mode. The machine will instruct you to adjust the throttle pedal to its minimum and maximum positions. The ECU will then record these values and adjust the sensor accordingly to match the operator’s input.
   
6. Verify Calibration: After the calibration process is complete, verify that the throttle response is smooth and consistent. Start the engine, test the throttle input, and observe if the RPM increases smoothly when the throttle is depressed and decreases without hesitation when released.
   
7. Test Under Load: To ensure proper calibration, test the machine under load by performing tasks like digging or lifting. The throttle should respond appropriately without delays or erratic behavior.
   

1. Check the Throttle Cable: The throttle cable may be stretched or damaged, preventing proper throttle input. Inspect the cable for wear and replace it if necessary.
   
2. Inspect the Throttle Pedal: The pedal itself may be binding or malfunctioning. Ensure that it moves freely and does not stick or cause delayed input.
   
3. Examine the Throttle Position Sensor (TPS): If the TPS is faulty or damaged, it may not send the correct signal to the ECU, even after calibration. In this case, replacing the TPS is necessary.
   
4. Check for ECU Issues: If all hardware components seem fine, the issue may lie with the ECU itself. A malfunctioning ECU may not be processing throttle input correctly. Diagnostic codes or a manual ECU check can help identify such problems.
