Mitsubishi Forklift FG30N Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system malfunction has been detected on the FG30N, such as severe engine or hydraulic failure. | Stop operation immediately and consult service support. | |
| Master Caution | AMBER | A non-critical fault or maintenance reminder has occurred, such as a minor sensor error or service interval. | Inspect the forklift soon and address any minor issues. | |
| Check Engine (MIL) | AMBER | The FG30N's engine management system has detected an electronic or emission-related fault. | Schedule diagnostic service to prevent performance loss. | |
| Engine Oil Pressure | RED | Oil pressure in the FG30N's engine is dangerously low, risking internal damage. | Shut off engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The alternator is not charging the battery or battery voltage is low in the FG30N. | Inspect the charging system and battery connections before resuming work. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe limits on your FG30N. | Stop the forklift, allow the engine to cool, and check coolant level. | |
| Brake System | RED | A fault in the FG30N's brake system or critically low brake fluid has been detected. | Do not operate; inspect brakes and fluid before use. | |
| ABS | AMBER | The anti-lock braking system has a fault and may not function as intended on the FG30N. | Use caution while braking and arrange for ABS service. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the FG30N. | Release the parking brake before driving. | |
| Low Fuel | AMBER | LPG fuel level is approaching empty in the FG30N's tank. | Plan to refuel soon to avoid unexpected downtime. | |
| Seat Belt | AMBER | The operator seat belt is not fastened while the FG30N is in use. | Buckle the seat belt before operating the forklift. | |
| Hydraulic System | AMBER | A hydraulic system issue such as low fluid or filter clog has been detected on the FG30N. | Check hydraulic fluid level and inspect for leaks or filter restrictions. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below recommended values in your FG30N. | Top up hydraulic oil and check for system leaks. | |
| Fuel Filter / Water Separator | AMBER | The FG30N's fuel filter is clogged or water is detected in the separator. | Replace the fuel filter and drain any water accumulation. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours logged on the FG30N. | Arrange for routine service to maintain reliability. | |
| Work Lights | BLUE | The FG30N's work lights are switched on for better visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active to alert others of FG30N movement. | Ensure the beacon is functioning in busy areas. | |
| Overload / Capacity | RED | The FG30N is attempting to lift a load above its rated capacity. | Lower the load immediately and verify load weight. | |
| Mast / Lift Limit | AMBER | Mast or lift height limit has been reached or a mast-related sensor is triggered on the FG30N. | Do not attempt to lift higher; check for obstructions or system faults. |

Frequently Asked Questions
What should I do if the master warning light appears on my FG30N?
Stop the forklift immediately and contact your service provider, as this indicates a critical fault requiring urgent attention.
Can I keep working if the check engine light is on but the forklift runs normally?
You may continue short-term, but schedule a diagnostic check soon to avoid possible long-term engine or emissions problems.
How often should I check the hydraulic oil level?
Inspect the hydraulic oil level at the start of each shift or daily, as low oil can cause performance and safety issues.
Why does the overload light come on even when I think the load is within limits?
Check the load center and verify the actual weight; uneven or improperly positioned loads can trigger the overload sensor.
What does it mean if the hour meter service light is on?
This means your FG30N has reached a scheduled maintenance interval and should be serviced soon to maintain warranty and performance.
