UniCarriers/Nissan PF80 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A severe malfunction or unsafe condition has been detected on the PF80, requiring the forklift to be stopped immediately. | Safely park the forklift and do not operate until the cause is diagnosed. | |
| Master Caution | AMBER | A non-critical issue or fault has been identified in one of the PF80's monitored systems. | Inspect the display for additional warnings and schedule maintenance soon. | |
| Check Engine (MIL) | AMBER | The engine management system has detected a fault specific to the PF80’s LPG or gasoline engine. | Continue operation cautiously and arrange for engine diagnostics. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low, risking severe engine damage in the PF80. | Shut down the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The alternator is not charging the PF80's battery, risking loss of electrical power. | Stop operation and inspect the charging system and belt. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high, indicating possible overheating in the PF80. | Turn off the engine and allow it to cool before checking coolant levels. | |
| Brake System | RED | A fault or low fluid level has been detected in the PF80’s brake system. | Cease operation and inspect the brake fluid and components. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the PF80. | Release the parking brake fully before moving. | |
| Low Fuel | AMBER | The PF80’s fuel tank is nearing empty, risking engine shutdown during operation. | Refuel the forklift as soon as possible. | |
| Hydraulic System | AMBER | A hydraulic system issue, such as low fluid or filter clog, is present on the PF80. | Check hydraulic fluid and filters, and address leaks or faults. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or quality is below recommended levels for safe PF80 operation. | Top up or replace hydraulic oil after verifying for leaks. | |
| Air Filter | AMBER | The PF80's engine air filter is restricted, reducing performance and efficiency. | Inspect and clean or replace the air filter. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter or water separator on the PF80 needs attention due to clogging or water accumulation. | Drain water and replace the filter as needed. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the PF80’s operating hours. | Arrange for service in accordance with the maintenance schedule. | |
| Work Lights | GREEN | The PF80’s work lights are currently switched on for improved visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The PF80’s beacon light is active to alert nearby personnel. | No action required; ensure beacon is functioning as needed. | |
| Overload / Capacity | RED | The PF80 is currently overloaded beyond its rated lifting capacity. | Lower the load immediately and verify weight limits. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level
- Faulty oil pump
- Oil leak
What to do
Stop the PF80 immediately, check the oil level and top up if low. If the light remains on, inspect for leaks and contact a qualified technician.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Thermostat failure
What to do
Turn off the PF80 and allow the engine to cool. Check coolant level and radiator for obstructions; do not continue operation until the issue is resolved.
Brake System
Common causes
- Low brake fluid
- Worn brake pads
- Hydraulic brake failure
What to do

Overload / Capacity
Common causes
- Exceeding rated load
- Incorrect load distribution
- Faulty load sensor
What to do
Reduce the load to within PF80 specifications and confirm proper load placement before operating further.
Battery / Charging
Common causes
- Alternator failure
- Loose or damaged belt
- Faulty battery
What to do
Inspect the alternator, belt, and battery connections on the PF80; replace or repair faulty components as needed.
Frequently Asked Questions
What should I do if the hydraulic warning light comes on while operating the PF80?
Stop operation, check the hydraulic fluid level, and inspect for leaks or filter clogs before continuing.
Is it safe to drive the PF80 when the check engine light is on?
You may continue operating briefly, but arrange for diagnostics soon, as unresolved engine issues can worsen.
How often should I service the PF80 when the hour meter light is on?
Follow the service intervals in the PF80’s manual, typically every 250 operating hours or as indicated.
Why does the air filter light come on frequently?
Dusty work environments may clog the PF80’s air filter faster; inspect and clean or replace the filter more regularly.
What does the overload light mean on my PF80 forklift?
The overload light indicates you are lifting more than the rated capacity; lower the load to prevent damage or accidents.
