| Master Caution | AMBER | A non-critical fault is present in the HX140L's systems, requiring attention soon to prevent escalation. | Check the monitor for specific fault codes and schedule service accordingly. | |
| Check Engine (MIL) | AMBER | The HX140L's engine management system has detected an emissions-related or performance issue. | Read diagnostic trouble codes using the service tool and address the underlying cause. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low on your HX140L, risking severe engine damage. | Stop engine immediately; check oil level and for leaks. Do not restart until resolved. | |
| Battery / Charging | RED | The HX140L's charging system is malfunctioning, battery voltage is low, or alternator is faulty. | Check battery terminals and alternator belt; charge or replace battery as needed. | |
| Coolant Temperature | RED | Engine coolant temperature in your HX140L has exceeded safe limits, risking overheating. | Stop engine, let it cool, check coolant level and radiator for blockages. | |
| Hydraulic System | AMBER | Hydraulic system temperature, pressure, or oil level is abnormal on the HX140L. | Check hydraulic oil level and temperature; inspect for leaks or overheating. | |
| Glow Plug / Preheat | AMBER | The HX140L's glow plugs are active during cold starts; it will turn off when preheating is complete. | Wait for the light to extinguish before starting the engine. | |
| Water in Fuel | AMBER | Water has been detected in the HX140L's fuel system, which can cause injector damage. | Drain the water from the fuel filter/separator as per the manual. | |
| Low Fuel | AMBER | Fuel level is low in the HX140L's tank; refuel soon to avoid engine stall. | Refill with clean diesel of the recommended grade. | |
| Air Filter | AMBER | The HX140L's engine air filter is restricted, reducing performance and fuel economy. | Clean or replace the air filter element according to the maintenance schedule. | |
| Service / Hour Meter | GREEN | Indicates that the HX140L is due for scheduled maintenance based on operating hours. | Perform the required maintenance as listed in the operator's manual. | |
| Work Lights | GREEN | The work lights on the HX140L are switched on, providing illumination for low-light operation. | No action needed; switch off when not required to save battery. | |
| Swing / Slew Lock | AMBER | The HX140L's swing lock is engaged, preventing upper structure rotation during transport or parking. | Release the swing lock before operating the excavator. | |
| Battery Discharge (BDI) | AMBER | Battery discharge indicator warns that the HX140L's battery is discharging faster than charging, often due to excessive electrical load. | Reduce electrical loads and check alternator performance. | |
| Overload / Capacity | RED | The HX140L has exceeded its rated load capacity, risking tipping or structural damage. | Immediately reduce the load; do not operate until within safe limits. | |
| Low Oil Level | AMBER | Engine oil level is low in the HX140L; continued operation may cause damage. | Check oil level and add recommended oil to the proper level. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on your HX140L is clogged and requires regeneration to clear soot. | Allow active regeneration by running the engine at high idle as per manual, or perform parked regeneration. | |
| Door Open | AMBER | The cab door of the HX140L is not fully closed; secure it for safety and noise reduction. | Close the door firmly and ensure the latch is engaged. |

Most Important Warning Lights
Master Warning (Stop) Light
Common causes
- Low engine oil pressure
- Engine coolant overheat
- Critical hydraulic system failure
What to do
Immediately shut down the HX140L's engine and consult the fault code display. Check oil and coolant levels, and inspect for leaks. Do not restart until the cause is identified and resolved; contact your Hyundai dealer if needed.
Engine Oil Pressure Light
Common causes
- Low oil level or oil pump failure
- Clogged oil filter
- Oil viscosity too thin
What to do
Stop the HX140L's engine at once. Verify oil level and top up with correct grade. If light remains, inspect for leaks or replace oil filter. If still on, do not operate and seek service.
Coolant Temperature Light
Common causes
- Low coolant level or leak
- Radiator blockage or fan failure
- Thermostat stuck closed
What to do
Turn off the HX140L's engine and let it cool. Check coolant level and top off with approved mixture. Clean radiator fins and check fan operation. If persists, have cooling system inspected.
Battery/Charging Light
Common causes
- Alternator belt loose or broken
- Faulty alternator
- Battery terminal corrosion
What to do
Check alternator belt tension and condition on your HX140L. Clean battery terminals and tighten connections. If light remains, have the charging system tested.
Overload Warning
Common causes
- Lifting beyond rated capacity
- Improper load distribution
- Sensors out of calibration
What to do
Reduce the load immediately on the HX140L. Ensure load is within specified limits and properly positioned. If light persists without overload, recalibrate the overload sensor system.
Frequently Asked Questions
What does the master warning red light on my HX140L mean?
It signals a critical fault such as low oil pressure or overheating; stop the engine and check the fault codes on the monitor. Do not operate until resolved.
Why is the hydraulic indicator amber on my HX140L?
The hydraulic system has an issue like high temperature or low oil level. Check the hydraulic oil level and temperature; reduce workload if overheating.
How do I reset the service hour meter on the HX140L?
The service reminder resets automatically after maintenance is performed using the diagnostic tool. Follow the manual for proper reset procedure.
Can I continue operating with the DPF regeneration light on?
No, you should allow regeneration to prevent filter damage. Run the engine at high idle or perform parked regeneration as described in the HX140L manual.
What does the swing lock light indicate?
The swing brake is engaged; release it before slewing the upper structure. This is normal when parking or transporting the HX140L.
Why does my HX140L show a water-in-fuel warning?
Water has accumulated in the fuel filter/separator. Drain it using the valve at the bottom of the separator to prevent injector damage.
