UniCarriers/Nissan CF80 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical malfunction has been detected by the CF80’s systems, potentially risking engine or hydraulic failure. | Safely stop the forklift immediately and investigate the source of the alert. | |
| Master Caution | AMBER | A non-critical fault has been identified by the CF80, such as a sensor error or minor system issue. | Check the display for further details and schedule service as soon as possible. | |
| Check Engine (MIL) | AMBER | The engine control module on your CF80 has detected a fault affecting emissions or performance. | Continue operation if safe, but arrange diagnostic service soon. | |
| Engine Oil Pressure | RED | The engine oil pressure has dropped dangerously low, risking severe engine damage in the CF80. | Stop the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The CF80 is not charging its battery, possibly due to alternator or wiring problems. | Shut down non-essential systems and have the charging system inspected. | |
| Coolant Temperature | RED | Engine coolant temperature is too high, indicating possible overheating in the CF80. | Stop operation immediately and allow the engine to cool before checking coolant level. | |
| Transmission Temp | RED | Transmission fluid temperature has exceeded safe limits, risking damage to the CF80’s transmission. | Pause operation and let the transmission cool; check fluid levels. | |
| Brake System | RED | A fault in the hydraulic brake system has been detected, reducing braking effectiveness. | Cease operation and inspect the brake fluid and system immediately. | |
| ABS | AMBER | The anti-lock braking system is malfunctioning, so the CF80 may not prevent wheel lockup. | Drive cautiously and arrange ABS repair. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the CF80. | Release the parking brake before moving the forklift. | |
| Low Fuel | AMBER | Fuel level is low, and the CF80 will soon require refueling to avoid stalling. | Plan to refuel at the next opportunity. | |
| DPF / Regeneration | AMBER | The diesel particulate filter needs regeneration due to soot buildup in the CF80. | Perform a DPF regeneration cycle as outlined in the operator manual. | |
| DEF / AdBlue | AMBER | DEF/AdBlue fluid is running low, which will affect emissions control on the CF80. | Refill the DEF/AdBlue tank promptly. | |
| Water in Fuel | AMBER | Water contamination has been detected in the diesel fuel system of the CF80. | Drain the water separator and check fuel quality. | |
| Hydraulic System | AMBER | A hydraulic system issue has been detected, possibly affecting lift or tilt functions. | Inspect hydraulic fluid levels and check for leaks. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is low in the CF80, risking poor lift performance. | Top up hydraulic oil and inspect for leaks. | |
| Engine Oil Temperature | RED | Engine oil temperature is excessive, threatening engine lubrication in the CF80. | Shut down the engine and allow it to cool before resuming work. | |
| Air Filter | AMBER | The air filter is clogged, reducing airflow to the CF80’s engine. | Replace or clean the air filter to restore performance. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or the water separator is full on the CF80. | Service or replace the fuel filter and drain separator. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on operating hours logged by the CF80. | Perform maintenance tasks as indicated in the service schedule. | |
| Work Lights | GREEN | Work lights are currently switched on to improve visibility around the CF80. | No action needed; turn off when not required. | |
| Beacon / Rotating Light | AMBER | The warning beacon is activated to alert nearby personnel to CF80 operation. | No action required unless beacon is malfunctioning. | |
| Overload / Capacity | RED | The CF80 has detected a load that exceeds its rated lifting capacity. | Lower the load immediately to prevent tipping or damage. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum lift height on the CF80. | Do not attempt to raise the mast further. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low oil level
- Oil pump failure
- Blocked oil filter
What to do
Stop the CF80 immediately, check and replenish oil if needed, and inspect for leaks or filter blockage before restarting.
Coolant Temperature Warning
Common causes
- Low coolant level
- Radiator obstruction
- Thermostat failure
What to do
Allow the engine to cool, check coolant level and radiator for obstructions, and consult service if the warning persists.
Overload / Capacity Warning
Common causes
- Attempting to lift a load above rated capacity
- Improper load distribution
- Faulty load sensor
What to do
Lower the load immediately, verify the weight and distribution, and inspect the load sensor for faults.
Hydraulic System Warning
Common causes
- Low hydraulic fluid
- Hydraulic leak
- Pump or valve malfunction
What to do
Check and top off hydraulic fluid, inspect for leaks, and have the hydraulic system serviced if issues continue.
Battery / Charging Warning
Common causes
- Alternator failure
- Loose or corroded battery connections
- Broken drive belt
What to do
Inspect the alternator, battery terminals, and drive belt; repair or replace faulty components to restore charging.
Frequently Asked Questions
What should I do if the DPF regeneration light stays on?
If the DPF light stays on, perform a parked regeneration following the CF80 operator manual, and service the filter if the light does not clear.
Why does the water-in-fuel light appear on my CF80?
This means water has accumulated in the fuel separator; drain the separator promptly to avoid injector or pump damage.
Can I continue working if the DEF/AdBlue warning is displayed?
You may continue briefly, but refill the DEF/AdBlue tank soon to prevent the engine from entering reduced power mode.
How often should I check the hydraulic oil on the CF80?
Check the hydraulic oil level daily before operation, especially after extended or heavy use.
What does the hour meter symbol mean on the CF80?
It indicates that scheduled maintenance or inspection is due based on your forklift’s operating hours.
