Takeuchi TB230 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | On the TB230, this red stop light illuminates when a critical fault is detected, such as engine overheating or low oil pressure. | Stop the machine immediately, check the display for the specific fault, and do not restart until resolved. | |
| Master Caution | AMBER | This amber light on the Takeuchi dash signals a non-critical issue like a clogged air filter or a service reminder. | Review the monitor for details and schedule maintenance soon; operation may continue with caution. | |
| Check Engine (MIL) | AMBER | The check engine light on TB230 indicates an engine emission or sensor fault, often related to the DPF or fuel system. | Contact your dealer to read fault codes; avoid prolonged use if the light flashes. | |
| Engine Oil Pressure | RED | When this red lamp glows on the TB230, oil pressure has dropped dangerously low, risking engine damage. | Shut off the engine immediately, check oil level and leaks, and tow to service. | |
| Battery / Charging | RED | The battery light on the TB230 warns of charging system failure, such as a broken alternator belt or faulty regulator. | Stop the engine and inspect the alternator and battery connections; the machine may run on battery power briefly. | |
| Coolant Temperature | RED | This red indicator on the Takeuchi TB230 signals engine coolant overheating, often from a blocked radiator or low coolant. | Stop the engine, let it cool, check coolant level and radiator fins, and clean debris. | |
| Hydraulic System | AMBER | The amber hydraulic light on the TB230 indicates low hydraulic oil level, high temperature, or a clogged filter. | Check hydraulic oil level and for leaks; clean or replace the filter and allow system to cool. | |
| Air Filter | AMBER | When the air filter light shows on a TB230, the engine air intake restriction has reached the limit. | Replace or clean the air filter element soon to maintain engine performance. | |
| Water in Fuel / Fuel Filter | AMBER | This warning on the TB230 means water has accumulated in the fuel filter/water separator. | Drain the water separator immediately; if light stays on, replace the filter. | |
| Glow Plug / Preheat | AMBER | The amber preheat light on the TB230 illuminates during cold starts to warm the intake air. | Wait for the light to turn off before cranking the engine; if it stays on, check glow plug relay. | |
| Seat Belt | RED | The seat belt reminder on the TB230 flashes red if the operator's belt is not fastened while the engine runs. | Fasten your seat belt immediately; the alarm will stop and safe operation is ensured. | |
| Low Fuel | AMBER | The low fuel light on the TB230 comes on when the tank has approximately 10% remaining. | Refuel as soon as possible to avoid running out and introducing air into the fuel system. | |
| Service / Hour Meter | GREEN | The green hour meter on the TB230 displays total operating hours and flashes when service is due. | Refer to the maintenance schedule; reset after performing required service. | |
| Work Lights | BLUE | The blue work light indicator on the TB230 shows that the auxiliary work lights are switched on. | No action needed; these lights improve visibility in dark conditions. | |
| Beacon / Rotating Light | BLUE | The blue beacon symbol on the TB230 confirms the rotating or strobe warning light is active. | Use the beacon when operating near pedestrians or traffic for safety. | |
| Swing / Slew Lock | AMBER | The amber swing lock light on the TB230 indicates that the upper structure swing is mechanically locked. | Ensure the lock pin is engaged before transport; disengage before normal operation. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Blocked radiator or hydraulic oil cooler
- Faulty thermostat or water pump
What to do
On the TB230, stop the engine immediately, clean debris from the radiator fins, check coolant level, and inspect the fan belt. If overheating persists, have the cooling system serviced by a dealer.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Clogged hydraulic filter
- Aeration or overheating of hydraulic fluid
What to do
Check the hydraulic oil sight gauge on the TB230; add recommended oil if low. Replace hydraulic filter and inspect hoses for leaks. Allow the system to cool before resuming work.
Battery/Charging System Issue
Common causes
- Worn alternator belt
- Failed alternator or voltage regulator
- Corroded battery terminals
What to do
On the TB230, inspect the alternator belt tension and check battery connections. If the red battery light stays on, have the charging system tested; the machine may run on battery power for a limited time.
Fuel Contamination
Common causes
- Water in fuel
- Dirty fuel filters
- Low-quality diesel
What to do
Drain the water separator on the TB230 daily; replace fuel filters if the water-in-fuel light remains. Use clean, high-quality diesel to prevent injector damage.
Seat Belt Not Fastened
Common causes
- Operator forgets to buckle up
- Faulty seat belt buckle sensor
- Seat belt retractor jam
What to do
Fasten the seat belt in the TB230; if the warning persists, inspect the buckle and wiring harness for damage. Do not bypass the system.
Frequently Asked Questions
What does the red stop light on my Takeuchi TB230 mean?
The red master warning (stop) light indicates a critical fault, such as low oil pressure or overheating. You must stop the engine immediately and diagnose the issue before restarting.
How do I reset the service hour meter on the TB230?
After performing scheduled maintenance, turn the key to ON, press and hold the dimmer/volume button for 5 seconds until the hour meter resets. Consult the operator's manual for exact steps.
Can I continue operating if the hydraulic light is on?
No, if the amber hydraulic light stays on, stop work and check the hydraulic oil level and temperature. Operating with low or overheated hydraulic fluid can damage pumps and motors.
Why does the glow plug light stay on after starting?
If the amber preheat light remains on after the engine starts, the glow plug relay or timer may be faulty. Have the system inspected by a dealer to ensure proper cold-weather starting.
What should I do if the water in fuel light comes on?
Drain the fuel filter/water separator immediately by opening the drain valve at the bottom. If the light doesn't go out, replace the filter element to prevent fuel contamination.
Is it safe to operate the excavator with the swing lock light on?
No, the swing lock indicator means the upper structure is mechanically locked. You must unlock it before attempting to swing; otherwise, severe damage can occur.
