Common Issues with the Takeuchi TB 125
Despite its generally solid performance, some operators report occasional issues with the TB 125. Here are a few of the most common:

1. Hydraulic System Leaks
   Like many compact excavators, the TB 125’s hydraulic system can be prone to leaks over time, especially in areas where the hydraulic hoses and fittings are under pressure.
   • Symptoms: Slow or unresponsive hydraulic movements, oil stains on the ground near the machine, reduced lifting power.
     
   • Solution: Regularly check hoses, seals, and fittings for signs of wear. If leaks are detected, replace the damaged parts and ensure the system is properly bled to remove air from the lines.
     
2. Engine Starting Issues
   Some owners have noted starting difficulties with the TB 125, often related to the fuel system or battery.
   • Symptoms: Difficulty starting, cranking without ignition, or a weak engine turnover.
     
   • Solution: Check the battery condition and ensure it's properly charged. Inspect the fuel filter for blockages and replace it if necessary. If the fuel system has air or debris, it may require purging or cleaning.
     
3. Undercarriage Wear
   The undercarriage on the TB 125 can experience wear and tear, particularly if used on rough terrain or without regular maintenance. Worn tracks or rollers can affect the machine’s stability and mobility.
   • Symptoms: Reduced traction, uneven movement, or grinding sounds.
     
   • Solution: Inspect the tracks, rollers, and sprockets for signs of wear. Regularly clean the undercarriage to remove dirt and debris. Replace any worn components to maintain optimal performance.
     
4. Electrical System Failures
   Electrical issues can sometimes affect the TB 125, with common problems such as faulty wiring, blown fuses, or malfunctioning switches.
   • Symptoms: Lights not functioning, electrical controls unresponsive, or error codes on the display.
     
   • Solution: Inspect the wiring for damage, especially near connections. Check the fuses and relays and replace them if needed. If there’s an issue with the wiring, seek professional assistance to avoid further damage.
