| Low Fuel | AMBER | Fuel level in the DX140LCR-5 tank is low, which can lead to air in the fuel system if ignored. | Refuel as soon as possible to avoid priming issues. | |
| Glow Plug / Preheat | AMBER | This indicator stays on briefly during cold starts on the DX140LCR-5 to preheat the combustion chamber. | Wait for the light to turn off before cranking the engine. | |
| Hydraulic System | RED | A serious hydraulic system fault on the DX140LCR-5 may cause loss of digging or travel functions. | Immediately stop operation and check hydraulic fluid level and for leaks. | |
| Parking Brake | RED | Indicates the parking brake on the DX140LCR-5 is engaged or malfunctioning. | Release the brake before moving; if light stays on, service the brake system. | |
| Swing / Slew Lock | BLUE | On the DX140LCR-5, this blue light shows the upper structure swing lock is engaged for transport or service. | Release the swing lock before operating the excavator. | |
| Work Lights | BLUE | Illuminates when the auxiliary work lights on your DX140LCR-5 are switched on. | Turn off work lights when not needed to save battery. | |
| Beacon / Rotating Light | BLUE | Indicates the rotating beacon on the DX140LCR-5 is active, warning nearby personnel. | Use beacon in low-visibility or job site conditions. | |
| Service / Hour Meter | AMBER | On the DX140LCR-5, this light reminds you that scheduled maintenance is due based on engine hours. | Perform the required service within the next 10 hours. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system of your DX140LCR-5, which can damage injectors. | Drain the water separator immediately and replace the fuel filter. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on the DX140LCR-5 needs regeneration to clear accumulated soot. | If safe, perform a parked regeneration following the machine procedure. | |
| Air Filter | AMBER | The air intake filter on the DX140LCR-5 is clogged, reducing engine power and efficiency. | Replace or clean the air filter element. | |
| Hydraulic Oil | RED | Hydraulic oil temperature or level on the DX140LCR-5 is critical, risking system failure. | Stop operation, check oil level and temperature; allow to cool if hot. | |
| Reduced Power (Limp Mode) | AMBER | The DX140LCR-5 has entered limp mode to protect the engine, limiting speed and load. | Identify the cause via diagnostic code and address the underlying fault. | |
| Engine Oil Temperature | RED | Engine oil temperature on the DX140LCR-5 is too high, risking oil breakdown and engine damage. | Reduce engine load and check cooling system and oil level. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Faulty thermostat or water pump
- Radiator blockage
What to do
On the DX140LCR-5, immediately stop the engine and allow it to cool. Check coolant level in the recovery tank and inspect for leaks. Clean radiator fins and ensure fan belt tension is correct.
Low Engine Oil Pressure
Common causes
- Insufficient oil level
- Oil pump failure
- Clogged oil filter
What to do
Shut down the DX140LCR-5 engine and check oil level with the dipstick. If low, add recommended oil. If light persists, inspect oil filter and pressure switch; consult dealer for internal issues.
Hydraulic System Failure
Common causes
- Low hydraulic fluid
- Contaminated fluid or filter
- Pump or valve malfunction
What to do
Stop the DX140LCR-5 and check hydraulic oil level in the sight glass. Look for external leaks. Replace hydraulic filter if clogged. Persistent issues require professional hydraulic diagnostics.
Battery Charging Failure
Common causes
- Faulty alternator
- Loose or corroded battery cables
- Failed battery
What to do
On the DX140LCR-5, verify alternator belt tension and condition. Tighten battery connections and clean corrosion. If light remains, test alternator output and replace if needed.
DPF Regeneration Required
Common causes
- Excessive idling or light load
- Engine not reaching operating temperature
- Clogged DPF due to soot buildup
What to do
Operate the DX140LCR-5 under load or perform a parked regeneration using the DPF switch. Ensure the machine is in a well-ventilated area. If regeneration fails, clean or replace DPF.
Frequently Asked Questions
What does the amber master caution light mean on the DX140LCR-5?
It indicates a non-critical issue such as low washer fluid or a service reminder. Check the multifunction display for specific warnings and address accordingly.
How do I reset the service hour meter on my Doosan DX140LCR-5?
After performing the required maintenance, access the service menu via the display buttons and select 'Reset Service Interval'. Confirm to clear the reminder.
The check engine light is on; can I continue working?
You may continue with reduced load, but avoid prolonged operation. Have the engine diagnosed as soon as possible to prevent emissions system damage or performance issues.
Why does the glow plug light stay on longer in cold weather?
The preheat system on the DX140LCR-5 requires more time to warm the combustion chamber in low temps. Wait for the light to turn off before cranking to ensure easy starting.
What should I do if the water in fuel light comes on?
Immediately drain the water separator located near the fuel tank. Replace the fuel filter to prevent injector damage. Check for contaminated fuel sources.
The reduced power light is flashing; what does it mean?
The engine control unit has detected a fault and is limiting power to protect the system. Reduce throttle and check for error codes in the display. Common causes include sensor failures or fuel issues.
