Komatsu Forklift forklift Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical malfunction has been detected in the Komatsu Forklift system, which may compromise safety or machine integrity. | Safely stop the forklift immediately and consult service support. | |
| Master Caution | AMBER | A non-critical system issue has been identified on your Komatsu Forklift, requiring prompt attention. | Inspect the cluster for additional warnings and schedule service soon. | |
| Check Engine (MIL) | AMBER | The engine control system has detected a fault specific to the Komatsu Forklift's powertrain. | Continue operation with caution; arrange diagnostic inspection at the next opportunity. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low, threatening severe engine damage in your Komatsu Forklift. | Shut down the engine at once and check oil level and leaks. | |
| Battery / Charging | RED | The charging system is not supplying power, risking battery depletion on the Komatsu Forklift. | Stop operation and inspect alternator, wiring, and battery connections. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded the safe limit for your Komatsu Forklift. | Turn off the engine to allow cooling and check coolant level and radiator. | |
| Transmission Temp | RED | Transmission fluid has overheated, which may cause damage to the Komatsu Forklift's drivetrain. | Stop using the forklift and allow the transmission to cool; inspect fluid levels. | |
| Brake System | RED | A malfunction in the braking system has been detected, affecting safe stopping on the Komatsu Forklift. | Cease operation and have the brake system inspected immediately. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the Komatsu Forklift. | Release the parking brake before moving the forklift. | |
| Low Fuel | AMBER | Fuel level is nearing empty, risking unexpected shutdown during Komatsu Forklift operation. | Refuel at the next available opportunity. | |
| Hydraulic System | AMBER | A hydraulic system fault or low fluid has been detected in your Komatsu Forklift. | Check hydraulic fluid and inspect for leaks or malfunctions. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below normal for the Komatsu Forklift's lifting system. | Top up hydraulic oil and inspect for possible leaks. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is higher than recommended for your Komatsu Forklift. | Pause operation to let the engine cool and check oil levels. | |
| Air Filter | AMBER | The air filter is clogged, restricting airflow to the Komatsu Forklift's engine. | Replace or clean the air filter promptly. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter or water separator requires attention due to clogging or water accumulation in the Komatsu Forklift. | Drain water and replace the fuel filter as soon as possible. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the Komatsu Forklift's operating hours. | Arrange for routine service according to the maintenance schedule. | |
| Work Lights | BLUE | The work lights are switched on to illuminate the Komatsu Forklift's operating area. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active on the Komatsu Forklift to alert nearby personnel. | Ensure beacon is functioning during forklift operation in active areas. | |
| Overload / Capacity | RED | The load exceeds the rated lifting capacity of the Komatsu Forklift, risking tip-over. | Lower the load immediately and verify weight before proceeding. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum lift height or a lift limit switch has been triggered on the Komatsu Forklift. | Do not attempt to raise the forks further; lower as needed. | |
| Battery Discharge (BDI) | AMBER | The battery discharge indicator shows that battery charge is low on the Komatsu electric forklift. | Recharge the battery soon to avoid operational interruptions. | |
| Fasten Seat Belt | AMBER | The operator seatbelt is not fastened, which is required for safe Komatsu Forklift operation. | Secure the seatbelt before starting or moving the forklift. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Blocked oil filter
What to do
Immediately stop the Komatsu Forklift, check and replenish oil if needed, and inspect for leaks or faulty components before restarting.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Failed thermostat
What to do
Turn off the engine to prevent overheating, allow to cool, then inspect coolant system for obstructions or leaks and top up coolant.
Overload / Capacity
Common causes
- Attempting to lift too much weight
- Incorrect load distribution
- Faulty load sensor
What to do
Lower the load to within rated capacity, verify load placement, and have sensors checked if warnings persist on the Komatsu Forklift.
Brake System
Common causes
- Hydraulic fluid loss
- Worn brake pads
- Brake line damage
What to do
Cease operation, check brake fluid and components, and arrange for immediate repair to ensure safe forklift operation.
Battery / Charging
Common causes
- Broken alternator belt
- Faulty alternator
- Loose battery terminals
What to do
Stop the forklift, inspect the charging system, and repair or replace faulty parts to restore proper battery charging.
Frequently Asked Questions
What should I do if the master warning light comes on in my Komatsu Forklift?
Stop the forklift immediately, check for additional warning indicators, and contact a qualified Komatsu technician for diagnosis.
Can I keep working if the hydraulic system light is amber?
You may continue operation briefly, but check hydraulic fluid levels and inspect for leaks as soon as possible to avoid damage.
Why does the overload indicator activate even with light loads?
This may be caused by a faulty load sensor—have it inspected and recalibrated by Komatsu service personnel.
How do I reset the service/hour meter reminder?
After completing scheduled maintenance, follow the procedure in the Komatsu Forklift's operator manual to reset the service reminder.
What does the BDI battery discharge light mean on my electric Komatsu forklift?
It signals that the battery is low; recharge it soon to prevent the forklift from shutting down during use.
Is it safe to operate with the air filter warning illuminated?
It's best to clean or replace the air filter promptly, as restricted airflow can reduce engine performance and lifespan.
