Komatsu Forklift FG35T-16 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A severe malfunction or critical safety issue has been detected in the Komatsu FG35T-16, requiring immediate shutdown. | Safely park the forklift and switch off the engine; investigate the cause before restarting. | |
| Master Caution | AMBER | A non-critical fault or cautionary condition has arisen, possibly affecting forklift performance. | Inspect the display for further details and address the issue as soon as possible. | |
| Check Engine (MIL) | AMBER | The engine management system has detected a fault specific to the Komatsu FG35T-16’s LPG engine. | Schedule a diagnostic check with a qualified technician to prevent further engine issues. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine damage. | Stop the engine immediately and check oil level and leaks before restarting. | |
| Battery / Charging | RED | The alternator is not charging the battery, risking electrical failure during operation. | Turn off non-essential electrical loads and have the charging system inspected. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe operating limits for the FG35T-16. | Shut down the engine and allow it to cool; check coolant level and radiator for blockages. | |
| Transmission Temp | RED | The transmission fluid temperature is abnormally high, threatening drivetrain integrity. | Stop operation and let the transmission cool down; inspect fluid levels and condition. | |
| Brake System | RED | A significant fault in the braking system has been detected, compromising safe stopping. | Cease operation and have the brake system checked before using the forklift again. | |
| Parking Brake | RED | The parking brake is engaged, preventing forward or reverse movement. | Release the parking brake before attempting to drive. | |
| Seat Belt | AMBER | The operator seatbelt is not fastened, which is a safety requirement on the FG35T-16. | Buckle the seatbelt before proceeding with forklift operation. | |
| Low Fuel | AMBER | The LPG fuel level is nearing empty, risking engine shutdown during operation. | Refill or replace the LPG tank at the next opportunity. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours logged on the FG35T-16. | Arrange for maintenance per the service schedule to maintain optimal performance. | |
| Work Lights | GREEN | The forklift’s work lights are currently switched on for improved visibility. | No action needed; turn off lights when not required to save battery. | |
| Beacon / Rotating Light | AMBER | The safety beacon is activated, alerting others to forklift movement. | No action needed; ensure beacon remains active in busy or low-visibility areas. | |
| Overload / Capacity | RED | The load on the forks exceeds the safe rated capacity of the FG35T-16. | Lower the load immediately and reduce weight to within specified limits. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level due to leaks or consumption
- Oil pump failure
- Blocked oil filter
What to do
Check the engine oil level and refill if needed; inspect for leaks and replace the oil filter if clogged. If pressure does not recover, contact a Komatsu service technician.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Thermostat malfunction
What to do
Allow the engine to cool, then check coolant level and radiator for obstructions. Top up coolant as necessary and have the thermostat inspected if overheating persists.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load distribution
- Faulty load sensor
What to do
Lower the load and verify it is within the FG35T-16’s rated lifting capacity. Reposition the load for balance and check for sensor faults if the warning continues.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads or shoes
- Hydraulic brake failure
What to do
Do not operate the forklift until the brakes are inspected and repaired. Check fluid level and replace worn components as needed.
Battery / Charging
Common causes
- Faulty alternator
- Loose or corroded battery terminals
- Worn drive belt
What to do
Inspect battery connections and alternator operation. Replace or tighten components as necessary and have the charging system tested.
Frequently Asked Questions
What should I do if the master warning light comes on while operating the FG35T-16?
Immediately stop operation, park the forklift in a safe area, and shut off the engine. Investigate the cause using the display or consult your supervisor before restarting.
How often should I service my Komatsu FG35T-16 based on the hour meter?
Follow the service intervals in the operator’s manual, typically every 250 hours for routine maintenance, or as indicated by the hour meter warning.
Can I continue to operate if the check engine light is on but the forklift seems to run normally?
It is not recommended; continued operation could worsen the underlying issue. Schedule a diagnostic check to identify and resolve the problem.
What does the overload warning mean?
This indicates the current load exceeds the forklift’s rated capacity. Lower the load immediately to avoid equipment damage or safety hazards.
Why does the seat belt warning stay on even when I am buckled in?
There may be an issue with the seat belt sensor or its wiring. Inspect the buckle and consult maintenance if the warning persists.
