Komatsu Forklift FD30T-16 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A severe malfunction or unsafe condition has developed on the FD30T-16, demanding you halt operation immediately. | Safely stop the forklift, switch off the engine, and investigate the cause before resuming. | |
| Master Caution | AMBER | A non-critical issue or system alert has been detected on the FD30T-16 that could affect performance if ignored. | Check the cluster for further details and address the indicated issue at the next safe opportunity. | |
| Check Engine (MIL) | AMBER | The engine management system has identified a fault affecting the FD30T-16's emissions or performance. | Continue with caution and schedule a diagnostic check as soon as possible. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped dangerously low, risking severe engine damage on the FD30T-16. | Shut down the engine immediately and inspect oil level and system for leaks or faults. | |
| Battery / Charging | RED | The charging system is not maintaining battery voltage, which may soon prevent the FD30T-16 from starting. | Check alternator belt and connections; avoid stopping the engine until resolved. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe limits, putting the FD30T-16 at risk of overheating. | Stop the forklift, allow the engine to cool, and inspect coolant level and radiator. | |
| Transmission Temp | RED | Transmission fluid temperature is excessively high, which can damage the FD30T-16's gearbox. | Cease operation and let the transmission cool before investigating fluid level and cooling system. | |
| Brake System | RED | A fault in the brake system has been detected, compromising the stopping ability of the FD30T-16. | Do not operate until the brake system has been thoroughly checked and repaired. | |
| Parking Brake | RED | The parking brake is engaged or not fully released while the FD30T-16 is in motion. | Fully release the parking brake before driving. | |
| Low Fuel | AMBER | Fuel level is low and the FD30T-16 will soon run out if not refueled. | Refuel at the next available opportunity to avoid work interruptions. | |
| Hydraulic System | AMBER | A hydraulic system fault or low fluid level has been detected on the FD30T-16. | Inspect hydraulic fluid level and check for leaks before resuming heavy lifting. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature is rising or oil level is insufficient, which can affect lifting performance. | Allow the system to cool and check oil level; top up or service if needed. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is clogged or water has accumulated in the separator on the FD30T-16. | Drain water and replace the fuel filter to maintain engine reliability. | |
| Service / Hour Meter | AMBER | The FD30T-16 is due for scheduled maintenance based on engine hours. | Arrange for service according to the maintenance schedule. | |
| Work Lights | BLUE | The work lights are switched on, improving visibility for the FD30T-16 operator. | No action needed unless lights are unintentionally left on. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active, alerting others to the FD30T-16's presence. | Ensure beacon is functioning when operating in shared or low-visibility areas. | |
| Overload / Capacity | RED | A load exceeding the rated capacity is being lifted, risking damage or tip-over of the FD30T-16. | Lower the load immediately and verify weight before proceeding. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum safe lifting height on the FD30T-16. | Do not attempt to raise the forks further; operate within specified limits. | |
| Battery Discharge (BDI) | AMBER | Battery charge level is low, indicating the FD30T-16 may soon lose electrical power. | Plan to recharge or replace the battery promptly. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Oil pump failure
- Blocked oil filter
What to do
Stop the FD30T-16 immediately and check engine oil level. If oil is sufficient, arrange for a qualified technician to inspect the lubrication system before further use.
Brake System Fault
Common causes
- Brake fluid leak
- Worn brake pads or shoes
- Hydraulic brake failure
What to do
Do not operate the forklift; have the brake system thoroughly inspected and repaired to restore safe operation.
Coolant Temperature Warning
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Shut down the engine and allow it to cool. Check coolant level and radiator for obstructions, and have the cooling system serviced if the problem persists.
Overload / Capacity Warning
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load distribution
- Faulty load sensor
What to do
Lower the load immediately and confirm its weight is within the FD30T-16's rated capacity. Inspect the load sensor if the warning persists without an actual overload.
Frequently Asked Questions
What should I do if the Master Warning (Stop) light comes on while operating the FD30T-16?
Immediately stop the forklift in a safe location, turn off the engine, and investigate the cause using the operator's manual or contact a qualified technician.
How often should I check hydraulic oil levels on the FD30T-16?
Hydraulic oil should be checked daily before operation to ensure proper function and to prevent system damage.
Can I continue working if the Check Engine (MIL) light appears?
You may continue operating with caution, but arrange for a diagnostic inspection as soon as possible to avoid potential engine damage.
What does the Overload / Capacity warning mean on my Komatsu FD30T-16?
This indicates you are attempting to lift a load exceeding the forklift's rated capacity, which can cause tipping or equipment failure; reduce the load immediately.
Why does the work lights indicator stay on after I turn off the ignition?
Work lights may remain on if manually switched; always ensure all auxiliary lighting is off before leaving the FD30T-16 to prevent battery drain.
