Common Problems

When you’re operating heavy machinery like the Hitachi EX1200-7B, it’s essential to be aware of potential issues that can arise. While this excavator is built to last, no machine is perfect. Here, we’ll dive into some common problems you might encounter and how to tackle them head-on.

Hydraulic System Issues

The hydraulic system is the lifeblood of any excavator, and the EX1200-7B is no different. While it generally performs well, there are a few issues that operators should keep an eye on:

• Leaks: Hydraulic fluid leaks can occur due to wear and tear on hoses and seals. Regularly inspect for any signs of fluid on the ground or around components.
• Slow Response: If you notice that the controls are sluggish, it could indicate low hydraulic fluid levels or a failing pump. Check the fluid levels and top them off if necessary.
• Overheating: The hydraulic system can overheat if it’s working too hard or if the fluid is contaminated. Monitor the temperature and ensure regular fluid changes to keep the system running smoothly.

Engine Performance Problems

The engine is another critical component that can present issues over time. Here are some common engine-related problems:

• Starting Issues: If the excavator struggles to start, it could be due to a weak battery or faulty starter. Regularly check the battery connections and replace the battery as needed.
• Loss of Power: If you notice a drop in power, it could be a sign of fuel delivery issues or air filter blockages. Inspect the fuel lines and replace the air filter regularly to maintain optimal performance.
• Excessive Smoke: Black or blue smoke can indicate incomplete combustion or oil leaks. If you see this, it’s time to have a mechanic take a closer look.

Electrical System Glitches

The electrical system in the EX1200-7B can sometimes be a source of frustration. Here are a few issues you might face:

• Faulty Sensors: If you receive warning lights or error codes, it could be due to faulty sensors. Regular diagnostics can help identify and replace any malfunctioning components.
• Wiring Problems: Damaged or corroded wiring can lead to intermittent issues. Inspect wiring regularly and replace any damaged sections to prevent further problems.
• Battery Drain: If the battery drains quickly, it could be due to parasitic draw from electrical components. Check for any devices that may be drawing power when the machine is off.

Track and Undercarriage Wear

The undercarriage is where the rubber meets the road, so to speak. It’s crucial to keep an eye on this area to avoid costly repairs:

• Track Wear: Over time, tracks can wear unevenly, leading to poor performance. Regularly inspect the tracks for signs of wear and replace them when necessary.
• Track Tension: Improper track tension can lead to premature wear. Make sure to adjust the tension according to the manufacturer’s guidelines.
• Roller and Idler Issues: The rollers and idlers can wear out, causing the tracks to slip or become misaligned. Regularly check these components and replace them as needed.

Operator Comfort and Ergonomics

While not a mechanical issue, operator comfort is crucial for productivity. Here are some common complaints:

• Poor Visibility: Some operators may find visibility lacking in certain positions. Adjust the seat and mirrors to maximize your view, and consider adding additional lighting if working in low-light conditions.
• Seat Comfort: The operator’s seat can become uncomfortable during long shifts. Consider investing in a seat cushion or replacement seat that offers better support.
• Control Layout: If you find the controls awkward, take the time to familiarize yourself with their layout. Some operators may benefit from additional training to improve efficiency.

Maintenance Challenges

Finally, maintenance can be a double-edged sword. While regular upkeep is essential, some aspects can be a hassle:

• Accessing Components: Some parts of the EX1200-7B can be tough to reach for routine checks. It’s crucial to have the right tools and a solid understanding of the machine to make maintenance easier.
• Parts Availability: Depending on your location, sourcing replacement parts can be a challenge. Establish a good relationship with local suppliers or consider online options for hard-to-find components.
• Time-Consuming Repairs: Some repairs can take longer than expected, leading to downtime. Always budget extra time for repairs and maintenance to keep your projects on track.
