Takeuchi TB125, TB135, TB145 Crawler Excavator Operators Manual (AG4E029)

On these Takeuchi TB125, TB135 and TB145 minis, you’re usually trenching, loading trucks, or working around foundations on tight, uneven jobsites. This operators manual is what I’d keep handy to explain what every control does, how the machine should feel under load, and what to check each day before you start swinging over trenches or traffic. If, for example, the machine feels jerky when you slew on a slope, this is the book I’d use to walk you through proper operating technique and basic checks before we assume something is wrong with the hydraulics.

Applications & Use Cases

• Teach new operators how to run the controls smoothly so they don’t shock-load the boom or tracks.
• Set up safe work habits for digging near utilities, foundations, or tight property lines.
• Guide daily inspections of fluids, tracks, and attachment pins to catch wear before it becomes downtime.
• Explain machine behavior on slopes, helping you position the upperstructure and blade for better stability.
• Reduce premature wear by showing proper warm‑up, cool‑down, and travel practices on rough ground.

FAQ

Q: Can I keep this manual on a tablet in the cab?

A: Yes, it’s handy to have a digital copy so you can zoom diagrams and search terms while you’re on site.

Q: Is it worth printing parts of this manual?

A: Many techs print the daily checks and control layouts so operators can reference them quickly in the container or workshop.

Safety Note

Always use the manual to verify safe operating positions and limits before working on slopes, near edges, or around other workers.
