| Battery / Charging | RED | The H80FT's charging system is not maintaining battery voltage. | Inspect alternator, connections, and battery condition before resuming use. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high in the H80FT. | Turn off the engine and allow it to cool; check coolant level and radiator. | |
| Transmission Temp | RED | Transmission fluid temperature has reached a critical level in the H80FT. | Stop the forklift and allow the transmission to cool before continuing. | |
| Brake System | RED | A malfunction has been detected in the H80FT's primary brake system. | Inspect brake fluid level and system integrity; do not operate until repaired. | |
| ABS | AMBER | The anti-lock braking system on the H80FT is not functioning correctly. | Operate with caution and have ABS serviced at the next opportunity. | |
| Parking Brake | RED | The parking brake is engaged on the H80FT. | Release the brake before attempting to drive. | |
| Seat Belt | RED | The operator's seat belt is not fastened while the H80FT is powered. | Securely fasten the seat belt before operating. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on the H80FT requires regeneration to maintain emissions compliance. | Complete a parked regeneration cycle as soon as possible. | |
| DEF / AdBlue | AMBER | DEF fluid level is low in the H80FT, risking emissions system faults. | Refill with the correct DEF fluid to avoid power reduction. | |
| Water in Fuel | AMBER | Water contamination detected in the H80FT's fuel system. | Drain the water separator promptly to prevent engine damage. | |
| Low Fuel | AMBER | The H80FT's fuel tank is nearing empty. | Refuel soon to avoid unexpected shutdown. | |
| Hydraulic System | AMBER | A fault or low pressure has been detected in the H80FT's hydraulic system. | Check hydraulic fluid level and look for leaks before further use. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or quality is below recommended limits in the H80FT. | Top up or replace hydraulic oil as specified in the manual. | |
| Engine Oil Temperature | AMBER | The engine oil temperature is higher than normal in the H80FT. | Monitor the temperature and reduce load if necessary. | |
| Air Filter | AMBER | The H80FT's air filter is restricted and airflow to the engine is limited. | Inspect and replace the air filter to restore performance. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter or water separator on the H80FT needs attention. | Service or replace the filter to prevent fuel delivery issues. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the H80FT's operating hours. | Arrange for required service to maintain reliability. | |
| Work Lights | GREEN | The H80FT's work lights are currently switched on. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The beacon is active, signaling forklift operation in the area. | Ensure beacon is used as needed for workplace safety. | |
| Overload / Capacity | RED | The H80FT is lifting a load that exceeds its rated capacity. | Lower the load immediately and verify weight before proceeding. | |
| Low Oil Level | AMBER | Engine oil level in the H80FT is below the minimum mark. | Add oil to the correct level before further operation. | |
| Brake Fluid Level | AMBER | Brake fluid is low in the H80FT's reservoir. | Fill with approved brake fluid and check for possible leaks. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Oil level too low
- Oil pump failure
- Blocked oil filter
What to do
Stop the H80FT immediately, check oil level, and inspect for leaks. If the issue persists after topping up oil, arrange for service to inspect the lubrication system.
Overload / Capacity
Common causes
- Attempting to lift excessive weight
- Incorrect load placement
- Faulty load sensor
What to do
Lower the load safely, confirm the weight is within the H80FT's capacity, and check load sensors if the warning recurs.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Thermostat failure
What to do
Turn off the H80FT, allow it to cool, check coolant level, and inspect the cooling system for obstructions or leaks before resuming use.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads
- Hydraulic brake failure
What to do
Do not operate the H80FT until the brake system is inspected and repaired by qualified personnel to ensure safety.
Battery / Charging
Common causes
- Faulty alternator
- Loose battery connections
- Aging battery
What to do
Inspect the charging system and battery terminals on the H80FT, and replace components as needed to restore reliable starting and operation.
Frequently Asked Questions
What should I do if the DPF regeneration light stays on?
For the H80FT, perform a parked regeneration as instructed in the operator manual; continued driving without regeneration can cause engine derate.
Why does the hydraulic system warning appear during operation?
This can indicate low hydraulic fluid, a leak, or filter clogging in the H80FT—stop and inspect the system before continuing.
Can I drive the H80FT with the ABS light on?
You can operate the forklift, but anti-lock braking is disabled, so use extra caution and schedule ABS service soon.
How do I reset the service/hour meter light?
After completing scheduled maintenance on the H80FT, reset the hour meter light using the cluster buttons as described in the manual.
What does the DEF/AdBlue warning mean?
The H80FT's DEF tank is low; refill with the correct grade DEF fluid to avoid emission system faults and engine derate.
