Despite its excellent design, the Hitachi EX200LC can experience several issues over time. Below are some of the most common problems reported by operators:
1. Hydraulic System Issues
Problem: One of the most common issues faced by EX200LC operators is related to the hydraulic system. Problems such as hydraulic fluid leaks, loss of hydraulic power, or sluggish operation can occur.
- Cause: Leaks may develop in hydraulic hoses or seals, reducing the system’s efficiency. Additionally, the hydraulic pump or valves could wear out with prolonged use, leading to reduced performance.
- Solution: Regularly inspect hydraulic hoses and fittings for signs of wear or leaks. If a leak is found, replace the damaged component immediately. If the hydraulic pump or valve is faulty, it may need to be repaired or replaced. Regular maintenance and cleaning of the hydraulic system can prevent many issues.
Problem: Another common issue is engine performance, where the EX200LC may experience a decrease in power, difficulty starting, or excessive exhaust emissions.
- Cause: A clogged fuel filter, malfunctioning fuel pump, or air intake problems can lead to poor engine performance. Additionally, a worn-out engine or a malfunctioning turbocharger can cause a drop in power.
- Solution: Inspect the fuel filter and fuel pump regularly and replace them if they are clogged or damaged. Ensure the air intake system is free from debris. If the engine is showing signs of wear, it may need a professional inspection to check the pistons, turbocharger, and other critical components.
Problem: Electrical issues are another common problem with the EX200LC. These issues include faulty sensors, issues with the battery charging system, and problems with the machine’s electrical connections.
