Adjusting crawler tension, doing the pre-shift walkaround, or chaining a compact excavator down for a trailer haul: that is the work this 263-page Takeuchi TB125, TB135, TB145 operator manual PDF (OEM ID AG4E022) is written to sit beside. Maintenance and specifications fill the largest share of the book, from service data and interval schedules to dimensions and operating range, while the safety chapter covers precautions from starting to transport. Lifting capacity tables let you check a load before the arm leaves the ground, and the options chapter covers the telescopic arm and air conditioner. Change the hydraulic oil return filter after the first 50 hours, then every 500, and torque the crawler tension grease discharge valve to 177 N·m (130 ft.lb.). One missing number can park a crew for a morning. Bookmarks jump straight to each chapter and the text layer finds service data fast, so the filters and fluids you order match your machine the first time.
