[MikePhua]

The TB035 is a popular model of mini excavator known for its compact size and versatile capabilities, ideal for work in tight spaces. However, like all machinery, it can encounter issues over time. This article provides insights into common problems and troubleshooting tips for the TB035 mini excavator to ensure it remains in peak working condition.
Common Issues with the TB035 Mini Excavator
While the TB035 is generally reliable, users have reported several common issues that may arise during operation. Here are some of the most frequently encountered problems:

1. Hydraulic System Issues:
   • A common concern for operators is the hydraulic system, which can suffer from leaks, low pressure, or contamination.
     
   • These problems often manifest as reduced performance or slow response when operating the boom, arm, or bucket.
     
   • To troubleshoot hydraulic issues, check for visible leaks around the hydraulic lines, cylinder seals, and pumps. Also, monitor the hydraulic fluid levels and ensure that the fluid is clean and at the proper level.
     
2. Electrical Problems:
   • Electrical issues in the TB035 can include faulty wiring, malfunctioning sensors, or issues with the ignition or starting system.
     
   • Users often experience intermittent power or failure to start the engine, which can be traced to loose connections, a bad battery, or a malfunctioning starter motor.
     
   • To resolve electrical problems, inspect the battery, wiring harness, and connectors for damage or corrosion. Ensure that the battery is properly charged and test the ignition system.
     
3. Engine Performance Issues:
   • Over time, the engine may suffer from poor performance, such as rough idling or difficulty starting.
     
   • These symptoms may be caused by clogged air filters, dirty fuel injectors, or issues with the fuel system.
     
   • Check the air filter and fuel system for blockages or contamination. Replacing the fuel filter and cleaning the injectors can help restore engine performance.
     
4. Track and Undercarriage Wear:
   • Given the compact design of the TB035, the undercarriage and tracks are subject to wear, especially when used on rough or uneven surfaces.
     
   • Operators may notice slack in the tracks, uneven wear, or difficulty in maneuvering the excavator.
     
   • Inspect the tracks for tightness and wear, and check for any damaged rollers or sprockets. Lubricate the rollers and adjust the track tension as needed to maintain proper operation.
     

Routine Maintenance to Prevent Issues
Regular maintenance is essential to ensure the longevity of the TB035 mini excavator and prevent potential issues. The following routine maintenance tasks should be performed to keep the machine in optimal condition:

1. Engine Maintenance:
   • Change the engine oil and oil filter at the recommended intervals to ensure proper lubrication and prevent engine wear.
     
   • Regularly inspect the cooling system for leaks or damage to prevent overheating during operation.
     
   • Replace the air filter periodically, especially if the excavator is used in dusty environments.
     
2. Hydraulic System Maintenance:
   • Check the hydraulic fluid regularly and top it off as needed. Make sure to use the recommended type of hydraulic fluid for the TB035.
     
   • Inspect hydraulic hoses and seals for wear or leaks. Replace any damaged parts immediately to avoid further damage to the system.
     
   • Clean the hydraulic filter regularly to maintain fluid cleanliness and prevent contamination.
     
3. Track and Undercarriage Care:
   • Inspect the tracks regularly for signs of wear, tension issues, or damage. Adjust the track tension if necessary to prevent uneven wear.
     
   • Lubricate the undercarriage components, including the rollers and sprockets, to reduce friction and extend their lifespan.
     
4. Electrical System Checks:
   • Regularly inspect the battery and wiring system to ensure proper function. Clean any corrosion from the battery terminals and check the voltage regularly.
     
   • If the machine is showing electrical issues, inspect fuses, sensors, and the ignition system for potential failures.
     
5. Greasing:
   • Use grease to lubricate the pivot points and other moving parts. This helps to reduce wear and friction, preventing issues like squeaky joints or stiff movements.
     

Troubleshooting Tips for the TB035 Mini Excavator
If you’re experiencing specific issues with your TB035 mini excavator, here are some additional troubleshooting tips:

1. Problem: Machine Won’t Start:
   • Check the battery for charge and condition. If the battery is old or low on charge, replace it or recharge it.
     
   • Inspect the starter motor and ignition system for any issues, such as faulty connections or worn-out parts.
     
2. Problem: Reduced Hydraulic Power:
   • If the machine is experiencing slow or weak hydraulic movements, check for hydraulic fluid leaks and ensure the hydraulic pump is functioning properly.
     
   • If the fluid is low or dirty, replace it and check the filter to ensure it's not clogged.
     
3. Problem: Uneven Track Wear:
   • If the tracks are showing uneven wear, check the track tension and adjust it as needed. Inspect the rollers and sprockets for damage or wear, and replace any faulty parts.
     

Conclusion: Keeping Your TB035 Mini Excavator in Top Shape
The TB035 mini excavator is a reliable machine, but like any equipment, it requires regular maintenance and occasional troubleshooting to remain in peak condition. By performing routine checks and addressing common issues such as hydraulic leaks, engine performance, and track wear, you can extend the lifespan of your machine and reduce the likelihood of costly repairs. If you encounter specific problems, following the tips in this guide will help you identify and resolve them quickly, ensuring that your TB035 continues to perform at its best.
