Common Issues and Solutions for Mini Excavators (Part 2)

In addition to starting difficulties, slow movements, and engine overheating, mini excavators may also encounter problems like track wear, hydraulic leaks, and electrical system faults during long-term use. This article continues to explore these issues and their solutions.

 

In addition to starting difficulties, slow movements, and engine overheating, mini excavators may also encounter problems like track wear, hydraulic leaks, and electrical system faults during long-term use. This article continues to explore these issues and their solutions.

 

4. Severe Track Wear

Issue:

Frequent operation on rough terrain can lead to track wear, affecting the machine’s stability.

 

Solution:

• Check track tension: Regularly adjust the tension of the tracks to avoid excessive wear.
• Replace worn-out tracks: When the tracks are heavily worn, replace them promptly.
• Operate on level ground when possible: Try to operate on flatter terrain to reduce track wear.

 

 

5. Hydraulic Leaks

Issue:

Hydraulic system leaks can affect the normal operation of the machine and may lead to more severe mechanical failures.

 

Solution:

• Inspect seals: Regularly replace aging or damaged seals.
• Check hydraulic lines: Ensure the hydraulic lines are free of cracks or looseness, and keep the system tightly secured.

 

 

6. Electrical Faults

Issue:

Electrical system problems may cause issues with the lights, displays, or starting system.

 

Solution:

• Inspect electrical wiring: Ensure the wiring is free from wear or loose connections.
• Replace fuses: If a fuse blows, replace it promptly to restore functionality.
• Ensure waterproofing: Prevent water from entering the electrical system, especially when operating in rainy or damp conditions.
