However, like all machines with electronic and hydraulic systems, the EX135 uses a series of warning lights to keep the operator informed of the machine’s condition. These lights provide an early warning for issues that may affect performance, safety, or operational efficiency.
Understanding the Warning Lights on the Fiat Hitachi EX135
The Fiat Hitachi EX135 is equipped with a range of warning lights on the dashboard, each designed to indicate a specific issue with the machine. Common warning lights include:
While warning lights are designed to alert operators to immediate issues, many of these problems can be prevented with regular maintenance. Following the manufacturer’s recommended maintenance schedule helps ensure the long-term reliability and performance of the Fiat Hitachi EX135. Key maintenance tasks include:
Real-World Example: Handling a Warning Light on a Hitachi Excavator
A construction company operating a fleet of Fiat Hitachi EX135 excavators encountered a situation where one of the machines kept triggering the hydraulic oil temperature warning light. Initially, they suspected a faulty sensor, but after further inspection, they discovered that the hydraulic fluid had become contaminated with debris, causing the system to overheat. The company performed a thorough flush of the hydraulic system, replaced the filters, and topped up the oil with the correct grade of fluid. Once these steps were completed, the warning light went off, and the machine resumed normal operation.
Conclusion
Warning lights on the Fiat Hitachi EX135 serve as a valuable tool for diagnosing potential problems before they lead to more serious and expensive repairs. Understanding the meaning behind each light, the common causes of the issues, and the steps to troubleshoot and resolve them is essential for maintaining the machine's health and ensuring maximum uptime. Regular maintenance and prompt attention to warning lights are critical in extending the life of the equipment and preventing costly breakdowns. By staying proactive and vigilant, operators can keep their Fiat Hitachi EX135 running smoothly for years to come.

However, like all machines with electronic and hydraulic systems, the EX135 uses a series of warning lights to keep the operator informed of the machine’s condition. These lights provide an early warning for issues that may affect performance, safety, or operational efficiency.
Understanding the Warning Lights on the Fiat Hitachi EX135
The Fiat Hitachi EX135 is equipped with a range of warning lights on the dashboard, each designed to indicate a specific issue with the machine. Common warning lights include:
- Engine Oil Pressure Warning Light:
This light illuminates when the engine oil pressure drops below safe levels. A drop in oil pressure can lead to serious engine damage, as it affects lubrication. Ignoring this warning can result in engine overheating, wear, or even complete failure.
- Coolant Temperature Warning Light:
When the engine coolant temperature rises beyond the normal operating range, this warning light will turn on. Overheating can damage internal components, leading to costly repairs if not addressed immediately.
- Hydraulic Oil Temperature Warning Light:
This light appears when the hydraulic system overheats. Hydraulic fluid is critical for smooth operation, and if the system gets too hot, it can lead to premature wear on components such as pumps, valves, and hoses.
- Fuel Level Warning Light:
A low fuel warning light is common on most machines, and the EX135 is no exception. This light activates when the fuel level in the tank is dangerously low, prompting the operator to refuel before the machine runs out of power.
- Battery Warning Light:
If there’s a problem with the charging system, such as a malfunctioning alternator or battery, this light will turn on. A dead or faulty battery can cause the machine to stop working altogether.
- Air Filter Warning Light:
This light indicates a blockage or restriction in the air intake system, often due to a dirty or clogged air filter. This can reduce engine efficiency and cause performance issues.
- Brake System Warning Light:
The brake system warning light comes on when there is an issue with the braking system, such as low brake fluid levels or hydraulic pressure loss. Operating a machine with faulty brakes is dangerous and should be addressed immediately.
- Engine Malfunction Light:
This light may appear if the engine control unit (ECU) detects a malfunction in the engine system. It’s often associated with a problem in the electrical or fuel system, and immediate diagnosis is required to prevent further damage.
- Transmission Warning Light:
When there is a problem with the transmission, such as low fluid levels or overheating, this light will illuminate. Transmission issues can severely affect performance and may lead to costly repairs if not resolved.
- Engine Oil Pressure Drop:
- Cause: Low oil levels, oil pump failure, or a clogged oil filter.
- Solution: Check the oil level immediately and top up if necessary. If the oil level is fine, inspect the oil pump and filter for blockages or damage. If the issue persists, the oil pressure sensor might need replacement.
- Cause: Low oil levels, oil pump failure, or a clogged oil filter.
- Engine Overheating:
- Cause: Low coolant levels, radiator blockage, or a malfunctioning thermostat.
- Solution: Start by checking the coolant level and topping it up if low. Inspect the radiator for blockages and clean it if needed. If the problem continues, the thermostat may need replacement.
- Cause: Low coolant levels, radiator blockage, or a malfunctioning thermostat.
- Hydraulic System Overheating:
- Cause: Low hydraulic oil levels, poor-quality hydraulic fluid, or a clogged hydraulic filter.
- Solution: Check the hydraulic fluid levels and refill if necessary. Replace the hydraulic fluid with the recommended type if it appears dirty or degraded. Inspect and clean the hydraulic filters.
- Cause: Low hydraulic oil levels, poor-quality hydraulic fluid, or a clogged hydraulic filter.
- Low Fuel Warning:
- Cause: Fuel tank nearing empty.
- Solution: Refuel the machine to avoid running out of power during operation. Regularly monitor fuel levels and avoid letting the tank run too low, as it can lead to air entering the fuel system.
- Cause: Fuel tank nearing empty.
- Battery or Charging System Issues:
- Cause: Faulty alternator, corroded battery terminals, or low battery charge.
- Solution: Inspect the alternator and check the battery charge. Clean the battery terminals of any corrosion and test the battery voltage. If the alternator is malfunctioning, it may need to be replaced.
- Cause: Faulty alternator, corroded battery terminals, or low battery charge.
- Clogged Air Filter:
- Cause: Dust or debris accumulation in the air filter.
- Solution: Remove and clean or replace the air filter. In dusty environments, it is recommended to inspect the air filter regularly to ensure optimal engine performance.
- Cause: Dust or debris accumulation in the air filter.
- Brake System Malfunction:
- Cause: Low brake fluid levels or hydraulic issues.
- Solution: Check brake fluid levels and top up as needed. Inspect the brake lines for leaks or damage and ensure proper hydraulic pressure. If the issue persists, the brake system may need to be bled or repaired.
- Cause: Low brake fluid levels or hydraulic issues.
- Transmission Problems:
- Cause: Low transmission fluid levels or overheating.
- Solution: Check the transmission fluid level and top it up if low. Inspect for leaks and ensure that the fluid is in good condition. If overheating is the cause, inspect the cooler for blockages.
- Cause: Low transmission fluid levels or overheating.
While warning lights are designed to alert operators to immediate issues, many of these problems can be prevented with regular maintenance. Following the manufacturer’s recommended maintenance schedule helps ensure the long-term reliability and performance of the Fiat Hitachi EX135. Key maintenance tasks include:
- Daily checks on fluid levels (oil, coolant, hydraulic fluid, and fuel) before operation.
- Periodic cleaning of the air filters and radiator to prevent blockages and ensure proper airflow.
- Inspection of hydraulic systems to check for leaks and maintain fluid levels.
- Regularly testing the brake system and checking for fluid leaks or wear on components.
