Komatsu Forklift FG50T-7 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major malfunction or hazardous condition has been detected in the FG50T-7, requiring you to stop operation immediately. | Cease forklift use and investigate the specific fault shown in the display panel. | |
| Check Engine (MIL) | AMBER | The engine management system has detected an abnormality in the FG50T-7's LPG engine operation. | Schedule inspection with a Komatsu technician and avoid heavy loads until checked. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe limits, risking severe engine damage in the FG50T-7. | Shut down the engine and check oil level and possible leaks immediately. | |
| Battery / Charging | RED | The charging system is not maintaining voltage, indicating possible alternator or battery issues on the FG50T-7. | Inspect battery terminals and alternator; do not continue operation if the issue persists. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high, risking overheating on the FG50T-7. | Stop the forklift, allow the engine to cool, and inspect coolant levels and radiator. | |
| Brake System | RED | A malfunction or fluid loss has been detected in the FG50T-7's braking system. | Do not operate; check brake fluid and system integrity before resuming use. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the FG50T-7. | Release the parking brake completely before driving. | |
| Low Fuel | AMBER | The LPG fuel level is nearing empty, risking unexpected shutdown of the FG50T-7. | Refill the LPG tank at the next safe opportunity. | |
| Seat Belt | AMBER | The operator seat belt is not fastened while the FG50T-7 is in use. | Secure the seat belt before continuing operation. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours logged in the FG50T-7. | Arrange for required service to maintain optimal performance. | |
| Hydraulic System | AMBER | A fault or low fluid condition has been detected in the FG50T-7's hydraulic circuit. | Inspect hydraulic fluid level and check for leaks or abnormal noises. | |
| Overload / Capacity | RED | The FG50T-7 is lifting a load beyond its rated capacity, compromising safety. | Lower the load immediately and check load weight against the forklift's capacity chart. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum lift height or a limit switch has been triggered on the FG50T-7. | Do not attempt to raise the forks further; lower the mast if necessary. | |
| Air Filter | AMBER | The air filter is clogged, reducing engine efficiency in the FG50T-7. | Inspect and clean or replace the air filter at the next service interval. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or water has accumulated, affecting fuel delivery in the FG50T-7. | Drain water from the separator and replace the filter if needed. | |
| Work Lights | BLUE | The FG50T-7's work lights are currently switched on for improved visibility. | Turn off the work lights when not needed to conserve battery power. | |
| Beacon / Rotating Light | AMBER | The overhead warning beacon is active, signaling forklift operation in the area. | Keep the beacon on during operation in shared or pedestrian zones. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Oil pump malfunction
- Oil filter blockage
What to do
Check and top up engine oil to the correct level, inspect for leaks, and replace the oil filter if needed. If the warning persists, have the oil pump inspected by a Komatsu service technician.
Coolant Temperature Warning
Common causes
- Coolant level is low
- Radiator or cooling fan failure
- Thermostat malfunction
What to do
Allow the engine to cool, check coolant level and refill as necessary, and inspect the radiator and fan for obstructions or faults. Persistent overheating should be addressed by a qualified technician.
Brake System Warning
Common causes
- Brake fluid leakage
- Worn brake pads or shoes
- Malfunctioning master cylinder
What to do
Inspect the brake fluid reservoir and top up if low, check for leaks and worn components, and do not operate the FG50T-7 until the braking system is fully functional.
Overload / Capacity Warning
Common causes
- Attempting to lift a load exceeding rated capacity
- Incorrect load distribution
- Faulty load sensor
What to do
Lower the load immediately, verify the weight and distribution, and ensure the load sensor is functioning correctly before resuming operation.
Frequently Asked Questions
What should I do if the Master Warning (Stop) light appears while operating the FG50T-7?
Immediately stop the forklift in a safe location and consult the instrument display for specific fault codes or messages. Do not continue operation until the issue is resolved.
How often should I check the hydraulic fluid on the FG50T-7?
Inspect the hydraulic fluid level daily before starting work, and top up as needed using the recommended hydraulic oil type for the FG50T-7.
Can I continue working if the air filter warning light is on?
You should address the air filter warning at the next available opportunity, as a clogged filter can reduce engine performance and increase fuel consumption.
What does it mean when the hour meter service light comes on?
The hour meter service light indicates that scheduled maintenance is due; arrange for servicing according to the FG50T-7's maintenance schedule to avoid potential breakdowns.
Is it safe to operate the FG50T-7 with the parking brake light on?
No, always ensure the parking brake is fully released before moving the forklift to prevent damage to the braking system and ensure safe operation.
