Takeuchi printed this 303-page operator manual for the TB290 hydraulic excavator under its own document number, AM3E004. In this Takeuchi TB290 owner's manual PDF, roughly a quarter of the book goes to maintenance, from the 10-hour daily inspection through the 4500-hour and two-year services, plus the fuel and lubricant table, tightening torque list, and safety-critical parts you replace on schedule. The controls chapter explains every warning lamp and indicator on the multi-information display, troubleshooting lists vehicle and engine error codes, and the specifications end with lifting capacities. Change the fuel filter every 500 hours, and hold the air between 294 and 490 kPa (43 to 71 psi) when you blow out the primary air cleaner element. On a remote job, there is nobody to ask. Chapter bookmarks and a searchable text layer take you straight to the interval or code you need.

Takeuchi TB290 Common Problems This Manual Covers
Takeuchi TB290 coolant temperature warning lamp lit and engine running hot during operation
Inspect the fan belt for slack or damage first. Check the coolant level after the engine has cooled down. Clean packed dirt and debris out of the radiator fins, then work through the rest of the cooling system for leaks following the Engine Overheating remedy procedure before putting the machine back to work.
Manual Section: Engine OverheatingAir cleaner warning lamp stays lit on the dash after startup and during digging
Check the air cleaner entry in Warning Lamp Troubleshooting, then remove the primary (outer) element. Clean it with dry compressed air at 294 to 490 kPa (43 to 71 psi) following page 186. Replace the element every 1000 hours or after 6 cleanings, whichever comes first, per page 155.
Manual Section: Maintenance p. 186Fuel filter warning lamp or water separator warning lamp lit on the monitor panel
Check which lamp is lit. Inspect the water separator and replace the fuel filter, which is due every 500 hours per page 155. On serial 185100001 or later, torque the fuel filter to 19.6 to 23.5 N·m following page 192; on serial 190200001 or later, torque the main fuel filter case to 29.4 N·m per page 193.
Manual Section: Maintenance p. 155Engine cranks but will not restart after running the fuel tank dry and refueling
Fill the tank first; capacity is 128 L per page 153. Bleed air from the fuel system before cranking again, following the Fuel System Troubleshooting steps for restarting after adding fuel. Verify the fuel level warning lamp is out before you try the starter again.
Manual Section: Fuel System TroubleshootingRubber track sagging, lugs worn down, or cracks showing in the crawler belt
Measure lug height and replace the rubber crawler when lugs reach 5 mm (0.2 in.), and check any cracks against the 60 mm (2.4 in.) repair limit on page 217. Check track tension at gap (A); a rubber crawler should sit at 160 to 180 mm (6.3 to 7.1 in.) per page 219.
Manual Section: Maintenance p. 217ECM error warning lamp lit with an engine error code showing on the display
Check the display and write down the SPN and FMI numbers, then match them in the Engine Error Code List on page 237. Check the Vehicle Error Code List on page 235 for any machine-side code shown alongside it. Write both codes on the work order before calling for service; the next tech needs them.
Manual Section: Engine Error Code List p. 237Frequently Asked Questions
How do I reset the Takeuchi TB290 radio?
To reset the radio, press the "4" button while simultaneously pressing the AST and AUX buttons. The display will show "JP" and the clock, indicating the radio is turned off and the memory in the preset buttons has been cleared. p. 103
How do I release residual auxiliary hydraulic pressure on a TB290?
Within 10 minutes of stopping the engine, turn the starter switch to the ON position. Then, press the auxiliary hydraulic switches several times to release the residual pressure in the auxiliary hydraulic circuitry. p. 106
How do I lower the boom when the TB290 engine is stopped?
For machines with an accumulator, perform this within 10 minutes of stopping the engine. Sit in the operator's seat, turn the starter switch to the ON position, lower the safety lock lever to the unlock position, and slowly push the operating lever forward to lower the boom. p. 109
