Hitachi ZX180LC-6 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system malfunction has been detected on the ZX180LC-6, such as severe engine or hydraulic failure. | Shut down the excavator immediately and investigate the fault via the display panel. | |
| Master Caution | AMBER | A non-critical fault or system irregularity has occurred, which may affect performance if not addressed. | Review the monitor for details and resolve the indicated issue at the next safe opportunity. | |
| Check Engine (MIL) | AMBER | The engine control system has logged a malfunction specific to the ZX180LC-6’s Isuzu engine management. | Check for diagnostic codes and schedule service as soon as possible. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped dangerously low, risking severe engine damage. | Stop the engine immediately and inspect oil level and system for leaks or pump failure. | |
| Battery / Charging | RED | The charging system is not maintaining voltage, possibly due to alternator or wiring issues. | Turn off unnecessary electrical loads and check the charging circuit promptly. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits for the ZX180LC-6. | Stop operation, allow the engine to cool, and check coolant level and radiator. | |
| Low Fuel | AMBER | Fuel level is low and the ZX180LC-6 will soon require refueling to avoid downtime. | Refuel at the next available opportunity to prevent engine stoppage. | |
| Hydraulic System | AMBER | A fault or abnormality has been detected in the hydraulic circuit, such as low pressure or high temperature. | Inspect hydraulic fluid level and check for leaks or filter blockages. | |
| Hydraulic Oil | AMBER | Hydraulic oil level is below the recommended range for safe operation. | Top up with approved hydraulic oil after checking for leaks. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is higher than normal, indicating possible overloading or cooling issues. | Reduce load and monitor temperature; investigate if warning persists. | |
| Air Filter | AMBER | The air filter is clogged, restricting airflow to the ZX180LC-6’s engine. | Clean or replace the air filter element promptly. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter is blocked or water has accumulated in the separator. | Drain water and replace the filter element as needed. | |
| Service / Hour Meter | AMBER | Scheduled maintenance interval has been reached based on engine hours. | Perform maintenance as per the ZX180LC-6 service schedule. | |
| Work Lights | BLUE | Work lights are currently switched on for improved visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active to warn others of machine operation. | Ensure beacon is functioning when operating in public or shared work zones. | |
| Swing / Slew Lock | AMBER | Swing lock is engaged, preventing upperstructure rotation on the ZX180LC-6. | Disengage swing lock before attempting to rotate the upperstructure. | |
| Overload / Capacity | RED | The machine has detected a lifting overload condition, exceeding safe capacity. | Lower the load immediately and reassess lifting plan. | |
| Door Open | AMBER | A cab or engine compartment door is not fully closed. | Secure all doors before continuing operation. | |
| Washer Fluid Low | AMBER | Windshield washer fluid reservoir is nearly empty. | Refill washer fluid to maintain clear visibility. | |
| DEF / AdBlue | AMBER | DEF (AdBlue) level is low, risking engine derate if not refilled. | Top up DEF tank with the correct fluid soon. | |
| DPF / Regeneration | AMBER | Diesel Particulate Filter requires regeneration to burn off soot. | Follow the regeneration procedure as indicated on the monitor. | |
| Water in Fuel | AMBER | Sensor has detected water in the fuel system, which can harm injectors. | Drain water from the fuel separator promptly. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Faulty oil pump
- Oil filter blockage
What to do
Stop the ZX180LC-6 immediately, check oil level and condition, and inspect the oil pump and filter before restarting.
Coolant Temperature Warning
Common causes
- Coolant leak
- Radiator blockage
- Failed thermostat
What to do
Let the engine cool, inspect for coolant leaks or blockages, and ensure the radiator and thermostat are functioning properly.
Overload / Capacity Warning
Common causes
- Attempting to lift a load above rated capacity
- Incorrect attachment use
- Malfunctioning load sensor
What to do
Lower the load immediately, verify attachment suitability, and check load-sensing components for faults.
Hydraulic System Warning
Common causes
- Low hydraulic fluid
- Leaking hoses or fittings
- Clogged hydraulic filter
What to do
Inspect and refill hydraulic fluid, check for visible leaks, and replace the hydraulic filter if necessary.
DEF / AdBlue Warning
Common causes
- DEF tank empty
- Incorrect DEF fluid
- DEF dosing system fault
What to do
Refill with approved DEF fluid and check the dosing system for errors; use only high-quality DEF to avoid system issues.
Frequently Asked Questions
What should I do if the DPF regeneration light comes on?
Initiate the regeneration process as instructed on the display, ensuring the ZX180LC-6 is in a safe location and following all on-screen prompts.
Is it safe to operate with the master caution light on?
You may continue working briefly, but check the monitor for the specific issue and address it at the earliest opportunity to prevent escalation.
How do I reset the service/hour meter reminder?
After completing scheduled maintenance, use the monitor’s menu to acknowledge and reset the service interval as outlined in the ZX180LC-6 manual.
Why does the swing lock light stay on?
The swing lock may still be engaged; ensure the lock lever or switch is fully disengaged before attempting to rotate the upperstructure.
What happens if I ignore the DEF/AdBlue warning?
If DEF levels run too low, the engine will eventually reduce power or may not start until the tank is refilled, so always replenish promptly.
