| Master Caution | AMBER | A non-critical fault has occurred in one of the ZX130-6’s monitored systems. | Check the monitoring panel for details and plan maintenance soon. | |
| Check Engine (MIL) | AMBER | The engine management system has detected an issue affecting performance or emissions in the ZX130-6. | Schedule diagnostic checks with a Hitachi technician at the next opportunity. | |
| Engine Oil Pressure | RED | Oil pressure has dropped below safe levels, risking engine damage in the ZX130-6. | Shut down the engine immediately and inspect oil level and leaks. | |
| Battery / Charging | RED | The alternator is not charging the ZX130-6’s battery, risking electrical failure. | Stop the machine and inspect the charging system before restarting. | |
| Coolant Temperature | RED | Coolant temperature has exceeded safe limits, indicating overheating in the ZX130-6. | Turn off the engine and allow it to cool; check coolant level and radiator. | |
| Low Fuel | AMBER | Fuel level is running low, risking unplanned shutdown during operations. | Plan to refuel the ZX130-6 as soon as possible. | |
| Hydraulic System | AMBER | A problem has been detected in the hydraulic system, which may affect boom or arm movement. | Inspect hydraulic fluid level and look for leaks or abnormal noises. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature or pressure is outside the recommended range on the ZX130-6. | Pause operation and check oil level and condition. | |
| Fuel Filter / Water Separator | AMBER | Water or contamination has been detected in the ZX130-6’s fuel filter assembly. | Drain the water separator and replace the filter if needed. | |
| DPF / Regeneration | AMBER | The diesel particulate filter needs regeneration to prevent engine restriction. | Follow the on-screen instructions to perform a parked or automatic regeneration. | |
| DEF / AdBlue | AMBER | The DEF/AdBlue tank is low or system fault detected, which may limit engine output. | Refill the DEF tank and check for system warnings. | |
| Water in Fuel | AMBER | Water contamination in the ZX130-6’s fuel system could harm injectors or engine. | Drain the water separator promptly. | |
| Air Filter | AMBER | The air filter is clogged, reducing engine efficiency in the ZX130-6. | Inspect and replace the air filter as soon as possible. | |
| Engine Oil Temperature | RED | Engine oil temperature is excessively high, risking lubrication breakdown. | Stop the engine and allow it to cool before checking oil and cooling systems. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the ZX130-6’s operating hours. | Arrange for the recommended service interval to be completed. | |
| Work Lights | BLUE | Work lights are switched on, improving visibility around the ZX130-6. | No action required unless lights are not needed. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active, alerting others to the ZX130-6’s presence. | No action needed unless beacon use is not required. | |
| Swing / Slew Lock | AMBER | The swing lock is engaged, restricting upperstructure rotation. | Disengage the swing lock before rotating the upperstructure. | |
| Overload / Capacity | RED | The ZX130-6 is operating beyond its rated lifting capacity. | Reduce load immediately to avoid structural or hydraulic damage. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low oil level
- Oil pump malfunction
- Blocked oil filter
What to do
Stop the ZX130-6’s engine right away, check the oil level and condition, and contact Hitachi service if pressure does not return after topping up.
Coolant Temperature Warning
Common causes
- Coolant leak
- Radiator blockage
- Faulty thermostat
What to do
Turn off the ZX130-6, let it cool down, inspect for visible leaks or obstructions, and refill coolant if necessary before restarting.
Overload / Capacity Warning
Common causes
- Lifting load exceeding rated capacity
- Incorrect use of attachments
- Improper load distribution
What to do
Lower the load to within the ZX130-6’s safe limits, re-evaluate lifting techniques, and consult the load chart in the operator’s manual.
Battery / Charging Warning
Common causes
- Alternator failure
- Loose or corroded battery terminals
- Broken drive belt
What to do
Inspect the alternator and battery connections on the ZX130-6, and repair or replace faulty components before resuming work.
Hydraulic System Warning
Common causes
- Low hydraulic oil level
- Hydraulic leak
- Contaminated oil
What to do
Check the hydraulic reservoir, inspect hoses and fittings for leaks, and replace oil or filters as specified for the ZX130-6.
Frequently Asked Questions
What should I do if the DPF regeneration light stays on?
Follow the instructions on the ZX130-6 display to initiate a parked regeneration; if the light remains, contact Hitachi service.
How often should I check the hydraulic oil level?
Check the hydraulic oil level daily before starting the ZX130-6 to ensure safe operation.
Why does the DEF/AdBlue warning light come on even after refilling?
The ZX130-6 may require a few minutes of operation to reset the DEF sensor; if the warning persists, there could be a sensor or system fault.
Can I continue working if the air filter warning is on?
It is best to replace or clean the air filter promptly on the ZX130-6 to avoid engine power loss and increased fuel consumption.
What does it mean if the swing lock light is illuminated?
The swing lock is engaged, preventing the upperstructure from rotating; disengage it before attempting to slew the ZX130-6.
Is it safe to ignore the hour meter/service light?
No, following scheduled maintenance is essential to keep the ZX130-6 running reliably and to prevent unexpected breakdowns.
