| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major fault has been detected on the FG30T-16, such as severe engine or hydraulic trouble, requiring an immediate stop. | Safely bring the forklift to a halt and investigate the cause before restarting. | |
| Check Engine (MIL) | AMBER | The engine control system has identified a malfunction affecting the FG30T-16's performance or emissions. | Schedule diagnostic service soon to prevent further engine issues. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe limits, risking severe engine damage in the FG30T-16. | Shut off the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The alternator is not charging the battery, which could lead to starting problems or loss of electrical power. | Inspect the alternator belt and charging system before continuing use. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high, putting the FG30T-16 at risk of overheating. | Stop the forklift, allow the engine to cool, and check coolant levels. | |
| Transmission Temp | RED | Transmission fluid temperature is above normal, which may damage the FG30T-16’s transmission. | Pause operation and allow the transmission to cool before resuming. | |
| Brake System | RED | A fault has been detected in the brake system, affecting stopping ability. | Cease operation and have the brake system inspected immediately. | |
| Parking Brake | AMBER | The parking brake is engaged, preventing the FG30T-16 from moving. | Release the parking brake before attempting to drive. | |
| Seat Belt | AMBER | The seat belt is not fastened while the operator is seated, reducing safety in the FG30T-16. | Fasten the seat belt before operating the forklift. | |
| Low Fuel | AMBER | The LPG fuel level is low and the FG30T-16 will soon require refueling. | Refill the LPG tank at the next opportunity to avoid work interruption. | |
| Hydraulic System | AMBER | A hydraulic system fault or low hydraulic fluid has been detected. | Inspect hydraulic fluid levels and check for leaks before further use. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the FG30T-16’s operating hours. | Arrange for routine service to maintain performance and warranty. | |
| Overload / Capacity | RED | The FG30T-16 is lifting a load that exceeds its rated capacity, risking tip-over or damage. | Lower the load immediately and ensure future lifts are within capacity limits. |
