| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe level in the HX220L; possible oil leak or pump failure. | Stop engine immediately and check oil level and pressure sensor. | |
| Battery / Charging | RED | The HX220L's charging system is not providing sufficient voltage; alternator or battery fault. | Inspect alternator belt and connections; test battery voltage. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded normal range in the HX220L; risk of overheating. | Stop engine, check coolant level and radiator fan operation. | |
| Hydraulic System | RED | A serious fault in the HX220L's hydraulic system, such as high temperature or low pressure. | Stop work and inspect hydraulic oil level and cooler. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature is high or filter restriction detected on the HX220L. | Check hydraulic oil level, condition, and clean the cooler. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is above normal but not critical; may be due to heavy load on the HX220L. | Reduce load and allow engine to cool; check oil level. | |
| Air Filter | AMBER | Air filter restriction detected in the HX220L; reduced engine performance may occur. | Inspect and replace air filter element. | |
| Fuel Filter / Water Separator | AMBER | Water has accumulated in the fuel filter or water separator of the HX220L. | Drain water from the separator and replace fuel filter if needed. | |
| DPF / Regeneration | AMBER | The HX220L's diesel particulate filter requires regeneration; exhaust temperature will rise. | Operate machine under load or initiate parked regeneration per manual. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust temperature is elevated during DPF regeneration on the HX220L; normal but avoid flammable areas. | Continue operation but keep machine away from combustibles. | |
| Low Fuel | AMBER | Fuel level in the HX220L's tank is low; refuel soon to avoid air in the system. | Refuel with clean diesel. | |
| Swing / Slew Lock | GREEN | The swing lock pin is engaged on the HX220L, preventing upper structure rotation. | Release swing lock before operating. | |
| Work Lights | BLUE | Work lights are turned on; visible on the HX220L for night operations. | No action needed; indicates lights are active. | |
| Beacon / Rotating Light | GREEN | The rotating beacon on the HX220L is active, warning nearby personnel. | No action needed; beacon is operational. | |
| Fasten Seat Belt | RED | The operator's seat belt is not fastened while the HX220L is in motion. | Stop machine and fasten seat belt. | |
| Reduced Power (Limp Mode) | AMBER | The HX220L has entered limp mode due to a detected fault in engine or drivetrain. | Finish current task and have the machine diagnosed. | |
| Service / Hour Meter | AMBER | Scheduled maintenance interval has been reached on the HX220L; service is due. | Perform required maintenance as per Hyundai's schedule. | |
| Low Oil Level | AMBER | Engine oil level is low on the HX220L; top up to prevent damage. | Check and add recommended engine oil. | |
| Door Open | AMBER | The cab door of the HX220L is not fully closed while machine is running. | Close and latch the door securely. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Radiator fan failure
- Blocked radiator fins
What to do
Stop engine immediately. Check coolant level after cooling. Clean radiator and test fan operation on the HX220L.
Hydraulic System Failure
Common causes
- Low hydraulic oil
- Pump cavitation
- Filter clogging
What to do
Shut down the HX220L. Inspect hydraulic oil level and add if low. Replace hydraulic filter and prime pump before restart.
DPF Clogged
Common causes
- Extended idling
- Low load operation
- Failed regeneration cycles
What to do
Perform a parked regeneration using the HX220L's control panel. If unsuccessful, consult a Hyundai dealer for forced regen or replacement.
Fuel System Air
Common causes
- Running out of fuel
- Loose fuel line connections
- Dirty fuel filter
What to do
Prime the fuel system using the HX220L's hand primer pump. Bleed air at the injection pump and replace the fuel filter if contaminated.
Swing Brake Malfunction
Common causes
- Worn brake pads
- Hydraulic pressure loss
- Sensor misalignment
What to do
Check swing brake pressure and adjust sensor on the HX220L. Replace brake pads if thickness is below spec.
Frequently Asked Questions
Why is the master warning light on while the engine is running?
On the HX220L, the master warning indicates a serious fault. Use the cluster display to identify the specific system; common causes include low oil pressure or high coolant temperature.
How do I initiate DPF regeneration on the HX220L?
Press and hold the regeneration button on the right console until the amber DPF light blinks. Ensure the machine is parked and away from combustibles; the process takes 20-40 minutes.
What does the swing lock indicator mean?
The green swing lock light means the mechanical lock pin is engaged, preventing upper structure rotation. Always disengage it before operating the excavator.
How often should I replace the air filter on the HX220L?
Replace the air filter when the indicator light illuminates or after every 500 hours of operation, whichever comes first. Clean the pre-cleaner daily in dusty conditions.
Can I operate with the hydraulic oil temperature light on?
No, the amber light warns of high temperature. Stop work and allow the hydraulic oil to cool. Check oil level and clean the cooler to prevent damage.
What does the fasten seat belt light indicate?
It alerts that the operator's seat belt is not fastened while the machine is in motion. The HX220L requires seat belt use for safety; stop and buckle up.
