Takeuchi TB216 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | Appears when a critical system failure occurs on your TB216, such as engine or hydraulic failure, demanding immediate action. | Stop the machine immediately, identify the accompanying warning light, and contact service. | |
| Master Caution | AMBER | Lights up for non-critical issues like low fuel or regenerative filter status on the TB216, signaling a need for attention soon. | Check the message center and address the underlying issue before continuing work. | |
| Check Engine (MIL) | AMBER | Indicates an engine management or emission control malfunction specific to the TB216's Yanmar engine. | Reduce load and have the engine diagnostics checked by a dealer. | |
| Engine Oil Pressure | RED | Warns of low engine oil pressure in the TB216, which can cause severe engine damage if ignored. | Shut off the engine immediately and check oil level and pressure. | |
| Battery / Charging | RED | Signals a charging system fault or low battery voltage on the TB216, often due to alternator or wiring issues. | Check battery connections and alternator output; charge or replace battery as needed. | |
| Coolant Temperature | RED | Lights when the TB216's engine coolant exceeds safe operating temperature, typically from heavy use or low coolant. | Stop the engine, let it cool, and check coolant level and radiator fins. | |
| Hydraulic System | RED | Alerts to a hydraulic system fault on the TB216, such as high oil temperature or low pressure, affecting excavator performance. | Stop work and inspect hydraulic oil level, filter, and for leaks. | |
| Parking Brake | RED | Reminds that the parking brake is engaged on the TB216; flashing may indicate a brake system fault. | Release the parking brake before moving, or inspect brake system if flashing. | |
| Glow Plug / Preheat | AMBER | Illuminates during cold start preheating on the TB216's diesel engine; goes out when ready. | Wait for the light to turn off before starting the engine. | |
| Water in Fuel | AMBER | Indicates water has accumulated in the TB216's fuel filter/water separator, which can cause injector damage. | Drain the water separator immediately and replace the fuel filter if necessary. | |
| Low Fuel | AMBER | Warns that the TB216's fuel level is low; continue operation may cause air ingestion in the fuel system. | Refuel as soon as possible to avoid fuel system issues. | |
| High Beam | BLUE | Indicates the high beam headlights are activated on the TB216 for improved visibility. | No action needed; dim when approaching other machines or people. | |
| Work Lights | GREEN | Shows that the auxiliary work lights on the TB216 are turned on, typically for low-light digging operations. | Turn off when not needed to conserve battery. | |
| Beacon / Rotating Light | BLUE | Confirms the rotating beacon on top of the TB216 is active, increasing visibility on job sites. | Ensure beacon is used according to site safety rules. | |
| Swing / Slew Lock | AMBER | Indicates the swing lock pin is engaged on the TB216, preventing upper structure rotation during transport. | Release the swing lock before operating the excavator. | |
| Service / Hour Meter | AMBER | Displays accumulated engine hours and triggers a warning when scheduled maintenance is due on the TB216. | Perform the required service per the TB216's maintenance schedule. | |
| Air Filter | AMBER | Alerts that the engine air filter on the TB216 is clogged, reducing engine power and fuel efficiency. | Clean or replace the air filter element. | |
| Engine Oil Temperature | RED | Warns of excessively high engine oil temperature in the TB216, which can degrade lubrication and cause engine wear. | Reduce engine load and check oil level, cooler, and fan belt. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Blocked radiator fins
- Faulty cooling fan
What to do
Stop the TB216 immediately and let the engine cool. Check coolant level and radiator cleanliness; clean or refill as needed. If persistent, inspect the fan and water pump.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic filter clogging
- Internal pump wear
What to do
Shut down the TB216 and check hydraulic oil level and condition. Replace the hydraulic filter if dirty. For continued issues, have the pump and valves tested by a dealer.
Low Engine Oil Pressure
Common causes
- Insufficient oil level
- Oil pump failure
- Worn engine bearings
What to do
Stop the engine immediately on the TB216. Check oil level and add if low. If pressure remains low, do not restart; call for service to inspect oil pump and internal components.
Charging System Failure
Common causes
- Loose or corroded battery terminals
- Failed alternator
- Broken serpentine belt
What to do
On the TB216, check battery connections for tightness and corrosion. Test alternator output and replace if below 13.5V. Inspect belt tension and condition.
Water in Fuel
Common causes
- Condensation in fuel tank
- Contaminated fuel delivery
- Faulty fuel cap seal
What to do
Drain the fuel/water separator on the TB216 immediately. Replace the fuel filter if water is present. Use fuel additives to prevent future water accumulation.
Frequently Asked Questions
What should I do if the master warning (red) light comes on my TB216?
Stop the machine immediately and check the accompanying symbol (e.g., engine oil, coolant). Refer to the manual for the specific fault and contact your Takeuchi dealer if needed.
How do I reset the service hour meter on a TB216?
The service interval light is reset by a dealer using diagnostic software. Do not attempt manual reset; follow the maintenance schedule to clear the warning.
Why is my TB216's hydraulic warning light on but no loss of power?
It may indicate a high hydraulic oil temperature or a minor sensor fault. Check hydraulic oil level and clean the cooler fins. If light stays on, have the system scanned.
Can I continue working if the amber caution light is on?
Yes, but only if the associated symbol indicates a non-critical issue like low fuel or air filter. Monitor the situation and address the cause during the next break.
What does the swing lock light mean on my TB216?
It shows that the swing lock pin is engaged, preventing the upper structure from rotating. Disengage the lock before operating to avoid damage.
How often should I check the water separator on the TB216?
Inspect daily for water accumulation, especially after refueling or in humid conditions. Drain as needed to prevent injector damage.
