UniCarriers/Nissan PF60 Dash Warning Lights: Symbols and Meanings

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.

How to read the colors: Red indicators demand immediate attention and usually signal critical issues, while amber lights suggest caution or required maintenance. Green and blue lights indicate normal operating conditions or active features.

UniCarriers/Nissan PF60 Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDA 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)AMBERThe 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 PressureREDEngine 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 / ChargingREDThe 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 TemperatureREDThe 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 SystemREDA critical brake fault has been detected, compromising the PF60’s braking ability.Stop using the forklift and have the brake system inspected immediately.
PParking BrakeAMBERThe parking brake is engaged or not fully released on the PF60.Release the parking brake fully before driving.
Low FuelAMBERThe PF60’s fuel level is low and will soon require refueling to avoid engine shutdown.Refuel the forklift at the next opportunity.
DPF / RegenerationAMBERThe diesel particulate filter on the PF60 needs regeneration to prevent clogging.Follow the regeneration procedure as outlined in the operator’s manual.
DEF / AdBlueAMBERThe 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 SystemAMBERA 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 MeterAMBERScheduled maintenance is due based on the PF60’s hour meter reading.Arrange for routine service as recommended in the maintenance schedule.
Overload / CapacityREDThe 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 BeltAMBERThe seat belt is not fastened while the PF60 is operating.Fasten the seat belt before proceeding.
Air FilterAMBERThe air filter is clogged, restricting airflow to the PF60’s engine.Inspect and replace the air filter as needed.
Fuel Filter / Water SeparatorAMBERThe fuel filter or water separator requires attention, which may affect engine performance on the PF60.Drain water and replace the filter if necessary.
Work LightsGREENThe PF60’s work lights are switched on for better visibility.No action needed unless lights are not required.
Beacon / Rotating LightAMBERThe 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)AMBERThe battery discharge indicator shows the PF60’s battery is nearly depleted.Recharge or replace the battery as soon as possible.
Mast / Lift LimitAMBERThe 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.
