Toyota Forklift 8FGCU20 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major fault has been detected in the forklift's critical systems and operation must be stopped immediately. | Safely park the forklift, turn off the engine, and investigate the cause before using the machine again. | |
| Master Caution | AMBER | A non-critical fault or maintenance issue has been identified that requires attention soon. | Check the display for additional details and schedule service at the earliest opportunity. | |
| Check Engine (MIL) | AMBER | The engine control system has detected a malfunction specific to the forklift's fuel or emission system. | Continue operation if safe, but arrange for diagnostic service as soon as possible. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below the safe limit, risking severe engine damage. | Shut down the engine immediately and check oil level; do not restart until the issue is resolved. | |
| Battery / Charging | RED | The charging system is not supplying power to the forklift's battery, risking a stall or no-start. | Stop operation and inspect the alternator, battery, and connections before proceeding. | |
| Coolant Temperature | RED | Engine coolant temperature is above the safe range, putting the engine at risk of overheating. | Stop the forklift, allow the engine to cool, and check coolant level and radiator for problems. | |
| Brake System | RED | A failure has been detected in the forklift's primary braking system, compromising stopping ability. | Cease operation immediately and have the brake system inspected and repaired. | |
| Parking Brake | RED | The parking brake is engaged while the forklift is running or in gear. | Release the parking brake before driving to prevent damage to the brake components. | |
| Low Fuel | AMBER | Fuel level is approaching empty, and the forklift will soon be unable to operate. | Refuel the forklift at the next opportunity to avoid unplanned downtime. | |
| Hydraulic System | AMBER | A fault or low fluid condition has been detected in the hydraulic system. | Inspect hydraulic fluid level and look for leaks; service as needed. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below normal, which can affect lifting performance. | Check and top up hydraulic oil; address any visible leaks promptly. | |
| Air Filter | AMBER | The forklift's air filter is clogged or restricted, reducing engine efficiency. | Inspect and clean or replace the air filter to maintain optimal engine operation. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is clogged or contains excess water, risking engine performance issues. | Drain water and replace the fuel filter as soon as possible. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the forklift's operating hours. | Arrange for routine service according to the maintenance schedule. | |
| Work Lights | GREEN | Work lights are switched on to illuminate the forklift's operating area. | No action needed unless lights are not functioning as expected. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active, signaling forklift operation in the area. | Ensure beacon is working for safety compliance. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum safe lifting height or load limit. | Lower the mast or reduce load to stay within safe operating parameters. | |
| Overload / Capacity | RED | The forklift is carrying a load exceeding its rated capacity, risking tip-over or damage. | Lower the load immediately and ensure future loads are within rated limits. |
