Mitsubishi Forklift FG25N Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A severe malfunction or unsafe condition has been detected that could damage the FG25N or endanger the operator. | Cease operation immediately and check the display for further details. | |
| Master Caution | AMBER | A non-critical fault or maintenance issue is present that may affect forklift performance if ignored. | Review the cluster for more information and address the issue at the next opportunity. | |
| Check Engine (MIL) | AMBER | The engine management system on the FG25N has detected a fault affecting emissions or performance. | Schedule service soon and avoid heavy loads until inspected. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine damage. | Shut down the engine immediately and check oil level before restarting. | |
| Battery / Charging | RED | The alternator is not charging the FG25N's battery, risking electrical failure. | Stop using electrical accessories and inspect the charging system promptly. | |
| Coolant Temperature | RED | The engine coolant temperature is dangerously high, threatening engine damage. | Turn off the engine and allow it to cool before checking coolant level. | |
| Transmission Temp | RED | Transmission fluid temperature has exceeded safe limits, which can damage the transmission. | Stop operation and let the transmission cool down before proceeding. | |
| Brake System | RED | A brake system malfunction or low brake fluid has been detected on the FG25N. | Do not operate until the brake system has been checked and repaired. | |
| Parking Brake | RED | The parking brake is engaged, preventing the FG25N from moving safely. | Release the parking brake before attempting to drive. | |
| Seat Belt | RED | The operator's seatbelt is not fastened, which is a safety violation on the FG25N. | Secure your seatbelt before operating the forklift. | |
| Low Fuel | AMBER | The LPG fuel level is nearing empty, risking engine shutdown during operation. | Refuel the LPG tank at the next safe opportunity. | |
| Hydraulic System | AMBER | A hydraulic system issue has been detected that could affect lifting or steering functions. | Inspect hydraulic fluid levels and look for leaks before continuing. | |
| Service / Hour Meter | AMBER | The FG25N is due for scheduled maintenance based on engine run hours. | Arrange for service as soon as possible to maintain reliability. | |
| Work Lights | GREEN | The FG25N's work lights are switched on for improved visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The overhead beacon is active, signaling forklift movement to nearby personnel. | Ensure the beacon is functioning in pedestrian areas for safety. | |
| Overload / Capacity | RED | The load on the FG25N exceeds the rated lifting capacity, risking tip-over. | Lower the load immediately and reduce to within safe limits. | |
| Air Filter | AMBER | The engine air filter is clogged, reducing performance and efficiency. | Inspect and replace the air filter at the earliest convenience. | |
| Fuel Filter / Water Separator | AMBER | Water or debris has been detected in the fuel filter, which can harm the engine. | Drain or replace the fuel filter promptly to prevent engine issues. | |
| Hydraulic Oil | AMBER | Hydraulic oil level is low or oil quality is poor, affecting lift and tilt functions. | Top up or change hydraulic oil as needed before heavy use. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum lift height or limit switch is engaged. | Do not attempt to lift further; lower the forks if necessary. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Oil pump failure
- Blocked oil filter
What to do
Stop the FG25N immediately, check oil level, and refill if needed. If the light remains on, arrange for a technician to inspect the lubrication system.
Coolant Temperature Warning
Common causes
- Low coolant level
- Radiator blockage
- Failed thermostat
What to do
Turn off the engine and allow it to cool. Inspect and top up coolant, check for leaks, and clean the radiator before restarting.
Overload / Capacity Warning
Common causes
- Attempting to lift a load over the rated capacity
- Incorrect load positioning
- Mast or forks damaged
What to do
Lower the load and ensure it is within the FG25N's capacity chart. Inspect for damage and avoid exceeding limits.
Brake System Warning
Common causes
- Low brake fluid
- Worn brake pads or shoes
- Brake line leak
What to do
Stop operation, check brake fluid, and inspect the brake system for leaks or wear before using the forklift again.
Battery Charging Warning
Common causes
- Loose or corroded battery terminals
- Alternator failure
- Broken drive belt
What to do
Inspect battery connections and alternator belt; if the issue persists, have the charging system serviced before further use.
Frequently Asked Questions
What should I do if the Master Warning (Stop) light comes on?
Immediately stop the FG25N, check for additional messages on the display, and do not operate until the cause is resolved.
How often does the FG25N require scheduled maintenance?
Maintenance intervals are based on the hour meter; check your operator’s manual but typically service is due every 250 hours.
Can I continue operating if the Check Engine light is on?
You may continue working for a short period, but arrange for service soon to prevent further issues or reduced performance.
Why does the Overload light activate even with a moderate load?
The mast angle or fork position may affect load sensing; ensure the load is centered and within the rated capacity.
What does the hydraulic oil warning mean?
It indicates low hydraulic oil level or degraded oil; check and top up or change the oil to maintain smooth lifting and steering.
