| Engine Oil Pressure | RED | Warns that engine oil pressure has dropped below safe limits in the ZX210LC-6. | Shut down the engine immediately and inspect oil level and condition before restarting. | |
| Battery / Charging | RED | Shows the alternator is not charging the battery, risking power loss in the ZX210LC-6. | Stop operation and check alternator belt, wiring, and battery connections. | |
| Coolant Temperature | RED | Signals engine coolant temperature is critically high in the ZX210LC-6. | Turn off the engine to prevent overheating and inspect coolant level and radiator. | |
| Hydraulic System | AMBER | Indicates abnormal hydraulic system pressure or temperature in the ZX210LC-6. | Inspect hydraulic fluid level and filters, and check for leaks before continuing. | |
| Hydraulic Oil | AMBER | Warns that hydraulic oil level is low or oil temperature is high in the ZX210LC-6. | Top up hydraulic oil and check for possible leaks or contamination. | |
| Low Fuel | AMBER | Alerts that the ZX210LC-6's fuel level is nearing empty. | Refuel as soon as possible to avoid unplanned shutdown. | |
| DEF / AdBlue | AMBER | Indicates low DEF/AdBlue level or system malfunction on the ZX210LC-6. | Refill DEF tank and check for system faults to maintain emissions compliance. | |
| DPF / Regeneration | AMBER | Notifies the operator that the Diesel Particulate Filter is regenerating or requires regeneration on the ZX210LC-6. | Follow on-screen prompts to allow or initiate regeneration as instructed. | |
| Water in Fuel | AMBER | Warns of detected water in the ZX210LC-6's fuel system, risking engine damage. | Drain water separator promptly to protect the fuel injectors. | |
| Fuel Filter / Water Separator | AMBER | Indicates the fuel filter is clogged or the water separator needs attention in the ZX210LC-6. | Replace the filter or drain water as indicated in the maintenance manual. | |
| Air Filter | AMBER | Shows the air filter is restricted, reducing engine efficiency in the ZX210LC-6. | Inspect and clean or replace the air filter element. | |
| Engine Oil Temperature | AMBER | Alerts that engine oil temperature is higher than normal in the ZX210LC-6. | Pause operation to let the engine cool and check for possible causes. | |
| Service / Hour Meter | AMBER | Reminds the operator that scheduled maintenance is due based on the ZX210LC-6's hour meter. | Perform the recommended service to maintain machine reliability. | |
| Parking Brake | RED | Shows the ZX210LC-6's parking brake is engaged, preventing movement. | Release the parking brake before attempting to travel. | |
| Work Lights | BLUE | Indicates the work lights are switched on for enhanced visibility on the ZX210LC-6. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | BLUE | Shows the beacon light is active, warning others of the ZX210LC-6's presence. | Ensure beacon is used as required on job sites. | |
| Swing / Slew Lock | AMBER | Indicates the swing lock is engaged, restricting upper structure rotation on the ZX210LC-6. | Disengage the lock before rotating the upper structure. | |
| Overload / Capacity | RED | Warns that the ZX210LC-6 is operating beyond its rated lifting capacity. | Reduce load immediately to prevent tipping or structural damage. |

Most Important Warning Lights
Engine Oil Pressure Low
Common causes
- Insufficient engine oil
- Oil pump failure
- Faulty oil pressure sensor
What to do
Check engine oil level and top up if needed, inspect for leaks, and have the oil pump and sensor checked by a Hitachi technician.
Coolant Temperature High
Common causes
- Low coolant level
- Radiator blockage
- Failed thermostat
What to do
Let the ZX210LC-6 cool, check coolant level and refill if low, inspect the radiator for debris, and test the thermostat for proper operation.
Hydraulic System Warning
Common causes
- Low hydraulic oil
- Clogged hydraulic filter
- Hydraulic pump malfunction
What to do
Top up hydraulic oil, replace the filter if necessary, and have a technician inspect the pump and system for faults.
DEF/AdBlue System Fault
Common causes
- DEF tank empty
- Contaminated DEF fluid
- DEF injection system failure
What to do
Refill with correct DEF fluid, flush contaminated fluid if needed, and have the DEF system diagnosed and repaired by authorized service.
Overload Warning
Common causes
- Lifting beyond rated capacity
- Incorrect load chart usage
- Unstable ground conditions
What to do
Lower the load to within rated limits, verify load charts, and reposition the ZX210LC-6 on stable ground before resuming work.
Frequently Asked Questions
What should I do if the master warning light comes on while operating my ZX210LC-6?
Immediately stop the machine, check the monitor for details, and address any critical faults before restarting.
How do I reset the service/hour meter reminder on my ZX210LC-6?
After completing scheduled maintenance, use the monitor panel to access the service menu and follow prompts to reset the interval.
Why does the DPF regeneration light keep appearing?
The DPF may not be completing its regeneration cycle; follow the on-screen instructions to perform a parked or manual regeneration as needed.
Can I continue working if only the master caution light is on?
You may continue working briefly, but check the monitor for the specific issue and arrange repairs or maintenance soon.
What causes the hydraulic oil warning on my ZX210LC-6?
This can result from low hydraulic oil, high oil temperature, or a clogged filter; inspect the system and top up or replace components as necessary.
How do I check for water in the fuel system?
Monitor the instrument cluster for the water in fuel light, and if illuminated, drain the water separator at the next safe opportunity.
