Komatsu Forklift FD25T-16 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major fault or safety issue has been detected in the FD25T-16 that could cause damage or unsafe operation. | Stop the forklift immediately and investigate the specific warning shown. | |
| Check Engine (MIL) | AMBER | The engine control system of the FD25T-16 has identified a malfunction that may affect performance or emissions. | Schedule service to diagnose and repair the engine system; avoid heavy loads. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine damage on the FD25T-16. | Shut down the engine immediately and check oil level and possible leaks. | |
| Battery / Charging | RED | The alternator is not charging the battery, or battery voltage is critically low on this forklift. | Stop operation and inspect the charging system and battery connections. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits on the FD25T-16, risking overheating. | Turn off the engine and allow it to cool; check coolant level and radiator. | |
| Low Fuel | AMBER | Diesel fuel level is low and the FD25T-16 will soon run out if not refueled. | Refuel the forklift at the next opportunity. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below recommended range, which may impair lift or tilt functions. | Inspect hydraulic oil reservoir and refill or check for leaks. | |
| Brake System | RED | A fault has been detected in the FD25T-16's brake system, reducing braking effectiveness. | Cease operation and have the brake system inspected immediately. | |
| Parking Brake | AMBER | The parking brake is engaged while the forklift is running. | Release the parking brake before driving. | |
| Fasten Seat Belt | AMBER | The operator seat belt is not fastened, which is a safety requirement for the FD25T-16. | Secure the seat belt before operating the forklift. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the FD25T-16's engine hours. | Arrange for routine service to maintain optimal performance. | |
| Work Lights | GREEN | Work lights are switched on to illuminate the forklift's operating area. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active to alert others of forklift operation. | Ensure beacon is functioning in high-traffic or low-visibility areas. | |
| Overload / Capacity | RED | The FD25T-16 is carrying a load above its rated capacity, risking tipping or structural damage. | Lower the load immediately and verify weight before continuing. | |
| Air Filter | AMBER | The engine air filter is clogged or restricted, reducing engine efficiency. | Inspect and clean or replace the air filter promptly. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is clogged or water has accumulated in the separator. | Drain water and replace the filter as needed. |

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 FD25T-16 immediately, check oil level and top up if needed. If the warning persists, arrange professional inspection before restarting.
Coolant Temperature Warning
Common causes
- Coolant leak or low coolant
- Radiator or fan malfunction
- Thermostat failure
What to do
Shut down the engine, allow it to cool, and inspect coolant level and hoses. Address any leaks or mechanical faults before resuming operation.
Overload / Capacity Warning
Common causes
- Attempting to lift loads beyond rated capacity
- Incorrect load positioning
- Unbalanced or shifting loads
What to do
Immediately lower the load and verify its weight. Always check load charts and ensure proper positioning to prevent equipment damage or accidents.
Brake System Warning
Common causes
- Brake fluid leak
- Worn brake pads or shoes
- Hydraulic brake failure
What to do
Do not continue using the forklift. Inspect the brake system for leaks or wear, and repair components as needed before returning to service.
Frequently Asked Questions
What should I do if the master warning light comes on while operating the FD25T-16?
Stop the forklift in a safe location, do not continue operation, and check the instrument panel for other warning lights to help identify the issue.
How often should I check the hydraulic oil level?
Inspect the hydraulic oil level daily before starting the FD25T-16, and top up as necessary to ensure smooth lifting and tilting.
Why does the fuel filter warning appear on my Komatsu FD25T-16?
This indicates the fuel filter is clogged or water has collected in the separator; drain the water and replace the filter to prevent engine issues.
Can I operate the forklift if the check engine light is on but the machine runs normally?
It is best to have the FD25T-16 checked by a technician soon, as continued use could lead to more serious problems or reduced performance.
What does the overload warning mean on the FD25T-16?
This means the forklift is lifting more than its rated capacity, which could cause tipping or mechanical failure; immediately lower the load and check the weight.
