Mitsubishi Forklift FGC20N Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has been detected by the FGC20N's control system, requiring an immediate stop to prevent equipment damage. | Safely stop the forklift and investigate the cause before restarting. | |
| Master Caution | AMBER | A non-critical fault or system alert has been registered, signaling that attention is needed soon. | Check the display for further details and plan corrective action. | |
| Check Engine (MIL) | AMBER | The FGC20N's engine management system has detected a malfunction affecting performance or emissions. | Schedule a diagnostic check to pinpoint and address the issue. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped dangerously low, risking severe engine damage. | Shut off the engine immediately and check oil level and system. | |
| Battery / Charging | RED | The battery is not charging properly, which may cause the FGC20N to lose electrical power. | Inspect the alternator, battery connections, and drive belt. | |
| Coolant Temperature | RED | The engine coolant temperature is excessively high, indicating overheating. | Stop the forklift, allow it to cool, and check coolant levels. | |
| Transmission Temp | AMBER | Transmission fluid temperature is above normal, which could lead to transmission issues. | Pause operation to let the transmission cool down. | |
| Brake System | RED | A fault in the braking system has been detected, reducing safe stopping ability. | Do not operate until the brake system is inspected and repaired. | |
| ABS | AMBER | The anti-lock brake system is malfunctioning on the FGC20N. | Proceed with caution and have the ABS system checked soon. | |
| Parking Brake | RED | The parking brake is engaged or not fully released. | Ensure the parking brake is fully disengaged before driving. | |
| Low Fuel | AMBER | The LPG fuel level is running low, risking unplanned shutdown. | Refuel with the correct LPG cylinder as soon as possible. | |
| Hydraulic System | AMBER | A hydraulic system issue has been detected, potentially affecting lift or tilt functions. | Inspect hydraulic fluid level and look for leaks. | |
| Fasten Seat Belt | RED | The operator seat belt is not fastened, disabling safe operation. | Buckle the seat belt before using the forklift. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on accumulated operating hours. | Arrange for routine service according to the hour meter reading. | |
| Work Lights | BLUE | The work lights are switched on, improving visibility for the operator. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The rotating beacon is active, alerting others to forklift movement. | Confirm beacon operation in high-traffic areas. | |
| Overload / Capacity | RED | The FGC20N has detected a load exceeding its rated capacity, risking tip-over. | Reduce the load immediately and operate within specified limits. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below optimal range. | Top up hydraulic oil and inspect for leaks. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is higher than normal, which may lead to engine wear. | Allow engine to cool and check for proper oil level. | |
| Air Filter | AMBER | The air filter is clogged, reducing engine efficiency. | Inspect and replace the air filter as needed. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or water is detected in the separator. | Drain water and replace the filter promptly. | |
| Mast / Lift Limit | AMBER | The mast has reached its lift height limit or a related sensor has triggered. | Do not attempt to lift higher; lower the mast if necessary. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Oil filter blockage
What to do
Check the oil level and refill if needed. If the warning persists, have a qualified technician inspect the oil system on the FGC20N before further use.
Coolant Temperature
Common causes
- Low coolant level
- Faulty radiator or fan
- Thermostat malfunction
What to do
Allow the engine to cool, then check coolant level and inspect for leaks. Replace faulty cooling components as necessary for the FGC20N.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Improper load distribution
- Faulty load sensor
What to do
Immediately reduce the load to within the FGC20N's rated limits and ensure proper load placement. If the warning remains, have the load sensor checked.
Brake System
Common causes
- Worn brake pads or shoes
- Brake fluid leak
- Hydraulic brake failure
What to do
Do not operate the FGC20N until the brake system has been thoroughly inspected and repaired by a qualified technician.
Battery / Charging
Common causes
- Loose or corroded battery terminals
- Alternator failure
- Drive belt slippage
What to do
Check and clean battery terminals, inspect the alternator, and ensure the drive belt is properly tensioned on the FGC20N.
Frequently Asked Questions
What should I do if the Master Warning (Stop) light comes on during operation?
Immediately stop the FGC20N in a safe location and investigate the cause, as this signals a critical system fault.
How often should the hydraulic oil be checked on the FGC20N?
Inspect hydraulic oil levels daily before use and top up as needed to prevent system issues.
Why does the Overload/Capacity light activate even when the load seems within limits?
Ensure the load is properly centered and secured; if the warning persists, the load sensor may need inspection.
Is it safe to operate the FGC20N with the ABS light on?
While basic braking remains, you should have the ABS system checked soon, as anti-lock functionality may be compromised.
What maintenance is triggered by the Service/Hour Meter indicator?
This light signals scheduled maintenance such as oil changes, filter replacements, and safety checks based on engine hours.
What does it mean if the Air Filter warning appears?
A clogged air filter is restricting airflow; replace it promptly to maintain engine performance on your FGC20N.
