Heli Warning Lights and Symbols: Complete Guide

HELI forklifts are widely used in industrial and warehouse environments, offering robust performance and reliability. The instrument cluster on a HELI forklift provides essential feedback about the machine's status, alerting operators to operational and safety issues in real time.

How to read the colors: Red lights indicate urgent problems requiring immediate attention, amber warns of cautionary or pending maintenance issues, while green and blue signify normal operational states or active functions.

Heli forklift Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDA major fault has been detected in a critical HELI forklift system, such as engine or hydraulics.Stop operation safely and investigate the source of the warning immediately.
Check Engine (MIL)AMBERThe engine control unit has identified a fault code affecting engine performance on this HELI forklift.Schedule a diagnostic check with a qualified technician at the earliest opportunity.
Engine Oil PressureREDEngine oil pressure has dropped below safe levels, risking severe engine damage in your HELI forklift.Shut down the engine immediately and check oil level and for leaks.
Battery / ChargingREDThe forklift's alternator is not charging the battery, or battery voltage is critically low.Stop operation and inspect the battery connections and alternator belt.
Coolant TemperatureREDThe engine coolant temperature has exceeded safe limits, risking engine overheating in your HELI forklift.Turn off the engine and allow it to cool before checking coolant level.
Brake SystemREDA malfunction or loss of pressure has been detected in the HELI forklift's brake system.Do not drive; inspect the brake fluid and system for leaks or faults.
ABSABSAMBERThe Anti-lock Braking System is not functioning, reverting brakes to standard operation.Operate with caution and have the ABS system checked soon.
PParking BrakeREDThe parking brake is engaged or has not been fully released.Release the parking brake before driving.
Low FuelAMBERThe fuel tank level is low and the HELI forklift will soon run out of fuel.Refuel at the next safe opportunity.
Hydraulic SystemAMBERA problem has been detected with the hydraulic system, such as low fluid or high temperature.Inspect hydraulic fluid level and look for leaks or overheating.
Hydraulic OilAMBERHydraulic oil level or pressure is below the required threshold for safe operation.Top up hydraulic oil and check for system leaks.
Engine Oil TemperatureREDEngine oil temperature is too high, risking engine damage in your HELI forklift.Stop the engine and allow it to cool before investigating the cause.
Air FilterAMBERThe air filter is clogged or dirty, reducing engine efficiency.Clean or replace the air filter as soon as possible.
Fuel Filter / Water SeparatorAMBERThe fuel filter is restricted or water has accumulated in the separator.Drain water and/or replace the fuel filter.
Service / Hour MeterAMBERScheduled maintenance is due based on engine hours recorded on your HELI forklift.Arrange for scheduled maintenance to avoid breakdowns.
Work LightsBLUEWork lights are switched on for improved visibility during operation.No action needed unless lights are not required.
Beacon / Rotating LightAMBERThe beacon or rotating warning light is active, signaling forklift movement.No action required unless the beacon is not functioning when needed.
Overload / CapacityREDThe forklift has detected a load exceeding its rated lifting capacity.Lower the load immediately and ensure compliance with load limits.
Mast / Lift LimitAMBERThe mast has reached its maximum safe height or a limit switch has been triggered.Lower the forks to a safe level before continuing.
Seat BeltREDThe seat belt is not fastened while the HELI forklift is in use.Fasten the seat belt before operating.
Fasten Seat BeltREDOperator seat belt reminder is active, indicating it is not buckled.Ensure the seat belt is properly fastened.
Battery Discharge (BDI)AMBERThe battery discharge indicator shows that battery charge is low on your electric HELI forklift.Recharge the battery soon to avoid shutdown.

Most Important Warning Lights

Engine Oil Pressure

Common causes

  • Low oil level
  • Oil pump failure
  • Blocked oil filter

What to do

Immediately shut down the HELI forklift, check the oil level, and inspect for leaks or a faulty oil pump before restarting.

Coolant Temperature

Common causes

  • Low coolant level
  • Radiator blockage
  • Faulty thermostat

What to do

Turn off the engine, let it cool completely, then check coolant level and inspect for blockages or a malfunctioning thermostat specific to your HELI model.

Overload / Capacity

Common causes

  • Attempting to lift an overweight load
  • Incorrect load positioning
  • Faulty load sensor

What to do

Lower the load immediately, verify it is within the rated capacity for your HELI forklift, and adjust placement if necessary.

Brake System

Common causes

  • Brake fluid leak
  • Worn brake pads
  • Damaged brake line

What to do

Do not operate the HELI forklift until the brake system is inspected and repaired by a qualified technician.

Battery / Charging

Common causes

  • Loose or corroded battery terminals
  • Alternator failure
  • Old or faulty battery

What to do

Check battery connections, ensure terminals are clean, and replace the battery or alternator if required for continued safe operation.

Frequently Asked Questions

What should I do if the hydraulic system light comes on during operation?

Stop the HELI forklift, check the hydraulic fluid level, and inspect for leaks or unusual noises before continuing work.

Why is the overload warning light on even with a small load?

This may indicate a malfunctioning load sensor or improper load positioning; have the system checked by a service technician.

How often should I check the air and fuel filters on my HELI forklift?

Inspect both filters during every scheduled maintenance interval and replace them if they appear dirty or clogged.

Can I operate the forklift if the ABS light is on?

You can operate the HELI forklift, but be aware that braking may not be as effective on slippery surfaces; arrange for ABS service promptly.

What does the BDI battery light mean on my electric HELI forklift?

It signals that the battery charge is running low and the forklift should be recharged soon to prevent unexpected shutdown.
