The UniCarriers/Nissan PF60 forklift is a rugged, diesel-powered material handling machine designed for demanding industrial environments. Its instrument cluster provides clear visual alerts to help operators maintain safe and efficient operation, ensuring long-term reliability and performance.
UniCarriers/Nissan PF60 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major fault or hazardous condition has been detected in the PF60 that requires the forklift to be stopped immediately. | Safely park the forklift and shut off the engine; investigate the cause before restarting. | |
| Check Engine (MIL) | AMBER | The PF60’s engine control system has identified a malfunction that may affect performance or emissions. | Schedule diagnostic service to prevent further engine issues. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped dangerously low, risking severe engine damage in the PF60. | Shut down the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The alternator is not charging the battery, so the PF60 may soon lose electrical power. | Stop operation and inspect the charging system and battery connections. | |
| Coolant Temperature | RED | The engine coolant temperature is excessively high, which can cause the PF60 to overheat. | Turn off the engine and allow it to cool before checking coolant level. | |
| Brake System | RED | A critical brake fault has been detected, compromising the PF60’s braking ability. | Stop using the forklift and have the brake system inspected immediately. | |
| Parking Brake | AMBER | The parking brake is engaged or not fully released on the PF60. | Release the parking brake fully before driving. | |
| Low Fuel | AMBER | The PF60’s fuel level is low and will soon require refueling to avoid engine shutdown. | Refuel the forklift at the next opportunity. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on the PF60 needs regeneration to prevent clogging. | Follow the regeneration procedure as outlined in the operator’s manual. | |
| DEF / AdBlue | AMBER | The DEF/AdBlue tank is nearly empty, which may restrict engine power in the PF60. | Refill the DEF/AdBlue tank promptly to maintain normal operation. | |
| Hydraulic System | AMBER | A hydraulic system issue has been detected, potentially affecting mast or steering functions on the PF60. | Inspect for hydraulic leaks or low fluid and address before further use. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the PF60’s hour meter reading. | Arrange for routine service as recommended in the maintenance schedule. | |
| Overload / Capacity | RED | The PF60 is lifting a load that exceeds its rated capacity, risking structural or tip-over hazards. | Lower the load immediately and ensure it is within the forklift’s safe limits. | |
| Seat Belt | AMBER | The seat belt is not fastened while the PF60 is operating. | Fasten the seat belt before proceeding. | |
| Air Filter | AMBER | The air filter is clogged, restricting airflow to the PF60’s engine. | Inspect and replace the air filter as needed. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter or water separator requires attention, which may affect engine performance on the PF60. | Drain water and replace the filter if necessary. | |
| Work Lights | GREEN | The PF60’s work lights are switched on for better visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The PF60’s beacon light is active to alert others of forklift operation. | No action needed; ensure beacon is functioning in required areas. | |
| Battery Discharge (BDI) | AMBER | The battery discharge indicator shows the PF60’s battery is nearly depleted. | Recharge or replace the battery as soon as possible. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum safe lift height on the PF60. | Do not attempt to raise the mast further. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Faulty oil pump
- Leaking oil lines
What to do
Immediately stop the PF60, check oil level and for visible leaks, and do not restart until the cause is corrected.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load positioning
- Worn or damaged forks
What to do
Lower the load to within the PF60's rated capacity, verify load placement, and inspect forks for damage before resuming work.
Coolant Temperature
Common causes
- Low coolant level
- Blocked radiator
- Malfunctioning cooling fan
What to do
Turn off the PF60 and allow it to cool, check coolant level and radiator for obstructions, and repair any cooling system faults.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads or shoes
- Hydraulic brake failure
What to do
Do not operate the PF60 until the brake system has been thoroughly inspected and repaired by qualified personnel.
Frequently Asked Questions
What should I do if the DPF regeneration light comes on while operating my PF60?
Follow the on-screen instructions or operator’s manual to initiate regeneration; avoid interrupting the process to prevent filter clogging.
Can I continue using the PF60 if the DEF/AdBlue light is on?
You can operate briefly, but refill the DEF/AdBlue tank as soon as possible to avoid reduced engine power or shutdown.
Why does the seat belt warning light remain on after buckling up?
Check for a fully latched belt and inspect the seat switch or buckle sensor for faults.
How do I reset the service/hour meter indicator on my PF60?
After completing scheduled maintenance, follow the reset procedure in the PF60’s service manual or consult your dealer.
What action should I take if the hydraulic system warning appears?
Inspect for hydraulic fluid leaks or low levels, and do not operate the PF60 until the issue is resolved.
