Hitachi ZX160LC-6 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault or severe abnormality has been detected in the ZX160LC-6, requiring the machine to be stopped immediately. | Safely park and shut down the excavator; consult the monitor for more details and arrange for diagnosis. | |
| Master Caution | AMBER | A non-critical malfunction or warning has been detected by the ZX160LC-6 monitoring system. | Check monitor messages and address the issue as soon as possible to avoid escalation. | |
| Check Engine (MIL) | AMBER | The ZX160LC-6 engine control system has logged a fault that could impact emissions or performance. | Inspect engine codes using the monitor and schedule maintenance. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low, risking severe engine damage in the ZX160LC-6. | Shut off the engine immediately and check oil level and leaks before restarting. | |
| Battery / Charging | RED | The charging system is not maintaining battery voltage in the ZX160LC-6. | Stop operation and inspect the alternator, wiring, and battery connections. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high, risking overheating damage to the ZX160LC-6. | Idle the engine to cool down, check coolant level and radiator, and stop if temperature does not drop. | |
| Hydraulic System | AMBER | The ZX160LC-6 hydraulic system has detected abnormal pressure or temperature. | Check hydraulic fluid level and filters; reduce workload and investigate further if the issue persists. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or quality is below specification in the ZX160LC-6. | Top up hydraulic oil and inspect for leaks or contamination. | |
| Low Fuel | AMBER | The ZX160LC-6 fuel tank is approaching empty and requires refueling soon. | Plan to refuel at the next opportunity to avoid machine downtime. | |
| DEF / AdBlue | AMBER | The DEF tank is low or there is an issue with the AdBlue system on the ZX160LC-6. | Refill DEF tank and check for system faults to maintain emissions compliance. | |
| DPF / Regeneration | AMBER | The diesel particulate filter requires regeneration to maintain exhaust flow on the ZX160LC-6. | Initiate parked regeneration as instructed on the monitor or continue operating at high load if possible. | |
| Water in Fuel | AMBER | Water contamination has been detected in the ZX160LC-6 fuel system. | Drain the water separator immediately to prevent injector or pump damage. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is clogged or the water separator needs service on the ZX160LC-6. | Replace the fuel filter and drain water as needed. | |
| Air Filter | AMBER | The engine air filter is restricted, reducing airflow in the ZX160LC-6. | Clean or replace the air filter to restore normal engine performance. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is elevated in the ZX160LC-6, increasing risk of wear. | Operate at reduced load and check oil cooler for obstruction. | |
| Parking Brake | RED | The parking brake is engaged while the ZX160LC-6 is in operation. | Disengage the parking brake before moving the machine. | |
| Work Lights | BLUE | The ZX160LC-6 work lights are switched on for better visibility. | No action needed; turn off when not required to save battery. | |
| Beacon / Rotating Light | AMBER | The beacon is active to alert others of ZX160LC-6 operation in the area. | No action needed unless working in a non-restricted area. | |
| Swing / Slew Lock | AMBER | The swing lock is engaged, restricting upperstructure rotation on the ZX160LC-6. | Release the swing lock before attempting to rotate the upperstructure. | |
| Service / Hour Meter | AMBER | Scheduled service or inspection is due based on ZX160LC-6 operating hours. | Plan maintenance as indicated in the service manual. | |
| Overload / Capacity | RED | The ZX160LC-6 is exceeding safe lifting or operational limits. | Reduce load immediately to prevent tipping or structural damage. |

Frequently Asked Questions
What should I do if the DPF regeneration light comes on?
Follow the monitor instructions to perform a parked regeneration or operate the ZX160LC-6 at high load to allow automatic regeneration.
Can I continue working if the master caution light is on?
You may continue with caution, but check the monitor for details and address the issue promptly to avoid escalation.
How do I reset a service/hour meter reminder?
After performing scheduled maintenance on the ZX160LC-6, use the monitor menu to reset the service interval according to the manual.
What causes the hydraulic oil warning to activate?
Low oil level, dirty hydraulic filters, or leaks in the hydraulic system can cause this warning on the ZX160LC-6.
Is it safe to operate with the swing lock engaged?
No, you must release the swing lock before rotating the upperstructure to avoid damaging the ZX160LC-6.
