Komatsu Forklift FG25T-16 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A severe fault has been detected in a core system of the FG25T-16, such as engine, transmission, or hydraulics. | Stop the forklift immediately and consult a Komatsu technician. | |
| Check Engine (MIL) | AMBER | The engine management system has identified a malfunction affecting engine performance or emissions. | Schedule diagnostic service soon; avoid heavy loads until checked. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped dangerously low, risking engine damage on the FG25T-16. | Shut off the engine immediately and check oil level before restarting. | |
| Battery / Charging | RED | The charging system is not maintaining voltage, risking battery depletion during operation. | Inspect alternator belt and battery terminals; do not continue use if unresolved. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits, indicating possible overheating. | Turn off the forklift and allow it to cool before checking coolant level. | |
| Brake System | RED | A failure or significant drop in hydraulic brake pressure has been detected. | Stop operation and inspect brake fluid and system for leaks. | |
| Parking Brake | AMBER | The parking brake is engaged or not fully released on the FG25T-16. | Release the parking brake before driving. | |
| Seat Belt | AMBER | The operator seat belt is not fastened while the forklift is in use. | Buckle the seat belt before operating. | |
| Low Fuel | AMBER | The LPG fuel level is low, risking engine shutdown if not refilled soon. | Refuel with LPG at the next opportunity. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below normal operating range. | Check for leaks and top up hydraulic oil if needed. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours logged by the FG25T-16. | Arrange for routine service per Komatsu maintenance schedule. | |
| Work Lights | GREEN | The work lights are switched on to improve visibility around the forklift. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The warning beacon is activated to alert nearby personnel of forklift movement. | Ensure beacon is functioning during operation in pedestrian areas. | |
| Overload / Capacity | RED | The forklift's load exceeds its rated lifting capacity, risking instability. | Lower the load immediately and verify weight before continuing. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Oil pump failure
- Oil filter blockage
What to do
Stop the FG25T-16 immediately, check oil level, and inspect for leaks or pump issues before restarting.
Coolant Temperature Warning
Common causes

Frequently Asked Questions
What should I do if the master warning light appears on my FG25T-16?
Stop the forklift immediately and contact a qualified Komatsu technician to diagnose the issue before continuing operation.
How often should I service my Komatsu FG25T-16 based on the hour meter?
Follow the maintenance intervals in the operator's manual, typically every 250 hours for routine service, or as indicated by the hour meter warning.
Can I drive with the check engine light on if the forklift seems to run normally?
It's best to schedule a service as soon as possible, as continued use could lead to further engine damage or increased emissions.
What does it mean if the overload light comes on even with a light load?
This may indicate a faulty load sensor or uneven load distribution; have the system inspected if the warning persists.
Why does the parking brake light stay on after releasing the lever?
The sensor may be misaligned or the brake may not be fully disengaged; ensure the lever is fully released and have the system checked if needed.
