The Takeuchi TB260 is a compact excavator equipped with an advanced instrument cluster that provides real-time status of engine, hydraulic, and electrical systems. Understanding these indicators is crucial for safe operation and preventing costly downtime.
Takeuchi TB260 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | When illuminated on the TB260, this indicates a critical system failure that requires immediate engine shutdown. | Stop the engine safely; investigate the cause or contact service. | |
| Master Caution | AMBER | This light signals that a non-critical system requires attention; the TB260 can continue operation but schedule inspection. | Check the display for specific fault codes and plan service soon. | |
| Check Engine (MIL) | AMBER | On the TB260, this indicates an engine control system fault that may affect emissions or performance. | Have the diagnostic codes read by a dealer as soon as possible. | |
| Engine Oil Pressure | RED | When lit in the TB260, engine oil pressure has dropped below safe operating level, risking severe engine damage. | Stop the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | This indicates the TB260's alternator is not charging the battery properly or the voltage is too low. | Check alternator belt tension and battery connections; recharge or replace as needed. | |
| Coolant Temperature | RED | Engine coolant in the TB260 has exceeded normal temperature, risking overheating and engine failure. | Stop engine, allow cooling, check coolant level and radiator for blockages. | |
| Hydraulic Oil | RED | Hydraulic oil temperature in the TB260 is too high, which can damage pumps and seals. | Reduce engine load and allow hydraulic system to cool; check oil level and cooler. | |
| Water in Fuel | AMBER | The TB260's fuel filter/water separator has detected water accumulation that can affect engine performance. | Drain water from the fuel filter bowl as soon as possible. | |
| Glow Plug / Preheat | AMBER | This indicator shows the TB260's preheat system is active; wait for it to turn off before starting the engine. | Turn the key to the preheat position and wait for the light to extinguish before cranking. | |
| Fuel Filter / Water Separator | AMBER | The TB260's fuel filter requires replacement or the water separator needs draining to maintain fuel flow. | Replace fuel filter and drain water separator per maintenance schedule. | |
| Air Filter | AMBER | The engine air filter on the TB260 is clogged, restricting airflow and reducing power. | Clean or replace the air filter element to prevent engine damage. | |
| Seat Belt | RED | In the TB260, this warns that the operator's seat belt is not fastened; safety system detects unbuckled status. | Fasten your seat belt before operating the excavator. | |
| Work Lights | GREEN | The TB260's auxiliary work lights are switched on, improving visibility in low-light conditions. | No action needed; turn off when not required to save battery. | |
| Swing / Slew Lock | AMBER | The swing lock on the TB260 is engaged, preventing the upper structure from rotating. | Release the swing lock before operating the excavator. | |
| Overload / Capacity | RED | The TB260 is approaching or has exceeded its lifting capacity, risking tip-over or structural damage. | Reduce load immediately and relocate to safer ground. | |
| Service / Hour Meter | AMBER | This indicates that the TB260 has reached a scheduled maintenance interval based on engine hours. | Perform the required service as outlined in the operator's manual. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Faulty cooling fan
What to do
Stop the engine and let it cool. For the TB260, check coolant level in the recovery tank and inspect the radiator for debris; clean fins with compressed air or water.
Hydraulic Oil Overheating
Common causes
- Low hydraulic oil level
- Blocked oil cooler
- Excessive continuous use
What to do
Reduce engine load and allow the hydraulic system to cool. On the TB260, verify hydraulic oil level and clean the oil cooler core located behind the radiator.
Water in Fuel System
Common causes
- Condensation in fuel tank
- Contaminated fuel supply
- Faulty water separator
What to do
Drain water from the fuel filter/water separator bowl on the TB260. If the light persists, replace the fuel filter to prevent injector damage.
Engine Oil Pressure Loss
Common causes
- Low oil level
- Oil pump failure
- Oil leak
What to do
Immediately stop the engine. For the TB260, check the oil level on the dipstick; if low, add recommended oil and inspect for visible leaks.
Electrical Charging System Failure
Common causes
- Alternator belt slippage
- Faulty alternator
- Loose battery connections
What to do
Check alternator belt tension on the TB260; tighten or replace if loose. Clean and tighten battery terminals; if still lit, alternator or voltage regulator may need replacement.
Frequently Asked Questions
What should I do if the Master Warning light comes on while operating my TB260?
Stop the engine immediately and investigate the cause. Check for simultaneous warning lights (e.g., oil pressure, coolant temp). Refer to the operator's manual for specific shutdown procedures.
How often should the fuel filter be changed on the Takeuchi TB260?
The fuel filter should be replaced every 500 hours or annually, whichever comes first. However, if the fuel filter warning light illuminates, replace it sooner and drain any water from the separator.
Why does the glow plug light stay on for a long time in cold weather?
The TB260's preheat system cycles longer in cold temperatures to ensure proper starting. Wait until the light turns off before cranking; if it stays on more than 30 seconds, have the glow plugs and relay checked.
Can I continue working if the Hydraulic Oil light comes on?
No. Stop work immediately and allow the hydraulic system to cool. Continued operation with high hydraulic oil temperature can damage pumps and seals. Check oil level and cooler cleanliness.
What does the Swing Lock indicator mean?
It means the swing lock is engaged to prevent the upper structure from rotating during transport or parking. Release it before operating the excavator; if it doesn't disengage, check the lock mechanism.
How do I reset the service hour reminder on the TB260?
After performing the required maintenance, turn the key to the ON position without starting, then press and hold the hour meter reset button for 5 seconds until the light turns off. Refer to your manual for exact steps.
