Clark GEX25 Dashboard Symbols and Warning Lights Explained

The Clark GEX25 is a robust electric forklift designed for demanding warehouse and industrial environments. Its instrument cluster provides vital feedback on the status and health of key vehicle systems, ensuring safe and efficient operation. Understanding each warning and indicator light is essential for maintaining optimal performance and operator safety.

How to read the colors: Red lights on the GEX25 signal immediate hazards or system failures that require stopping the forklift. Amber lights indicate caution or maintenance needs, while green and blue lights show normal operation or active functions.

Clark GEX25 Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDA critical system failure or dangerous condition has been detected on the GEX25, such as severe electrical or hydraulic issues.Stop the forklift immediately and investigate the warning source before continuing.
Master CautionAMBERA non-critical fault or maintenance reminder is present, such as scheduled service due or minor sensor alerts.Check the display for detailed information and address the issue at the next safe opportunity.
Check Engine (MIL)AMBERThe GEX25’s onboard diagnostics have detected an engine or drive system fault, possibly affecting electric motor performance.Schedule inspection with maintenance to diagnose and resolve the fault.
Battery / ChargingREDThe main traction battery is critically low or not charging correctly, risking unexpected shutdown.Cease operation and connect the forklift to a charger as soon as possible.
Brake SystemREDA fault has been detected in the GEX25’s braking system, such as low brake fluid or hydraulic failure.Do not operate—inspect brakes and fluid levels before resuming use.
ABSABSAMBERThe anti-lock braking system is malfunctioning, which may reduce brake stability on slippery floors.Drive with caution and arrange ABS system inspection.
PParking BrakeREDThe parking brake is engaged or not fully released, preventing normal driving.Release the parking brake before moving the forklift.
Seat BeltAMBERThe operator’s seat belt is not fastened while the GEX25 is powered on.Buckle the seat belt to ensure operator safety.
Hydraulic SystemAMBERA hydraulic system issue, such as low pressure or overheating, has been detected.Reduce hydraulic use and have the system checked soon.
Service / Hour MeterAMBERThe forklift is due for scheduled maintenance based on hours of operation.Arrange for servicing to maintain warranty and performance.
Work LightsGREENThe GEX25’s work lights are currently switched on for improved visibility.No action needed unless lights are not required.
Beacon / Rotating LightAMBERThe warning beacon is active, signaling the forklift is operating in the area.No action needed unless beacon is malfunctioning.
Battery Discharge (BDI)AMBERThe battery discharge indicator shows the battery is approaching its minimum charge threshold.Plan to recharge soon to avoid automatic power cut-off.
Overload / CapacityREDThe load on the forks exceeds the GEX25’s rated capacity, risking tip-over or damage.Immediately lower the load and reduce weight to within safe limits.
Mast / Lift LimitAMBERThe mast or lift has reached its maximum height or a lift limit switch is engaged.Lower the forks before attempting further lifting.

Most Important Warning Lights

Master Warning (Stop)

Common causes

  • Serious electrical system failure
  • Critical hydraulic leak
  • Major drive system malfunction

What to do

Immediately stop the GEX25, turn off the power, and have a qualified technician inspect the forklift before further use.

Battery / Charging

Common causes

  • Battery deeply discharged
  • Charging circuit fault
  • Loose battery connections

What to do

Connect the forklift to the charger and inspect battery terminals for tightness; if the issue persists, call for service.

Overload / Capacity

Common causes

  • Load exceeds rated lifting capacity
  • Incorrect load distribution
  • Faulty load sensor

What to do

Lower the load immediately, verify the load weight, and ensure proper load placement; if warning remains, have the system checked.

Brake System

Common causes

  • Low brake fluid
  • Hydraulic brake leak
  • Brake actuator fault

What to do

Inspect the brake fluid reservoir and lines for leaks; replenish fluid if low and repair any leaks before operating.

Hydraulic System

Common causes

  • Low hydraulic oil level
  • Hydraulic pump overheating
  • Clogged hydraulic filter

What to do

Check hydraulic oil level and top up if necessary; if overheating or filter issues persist, schedule maintenance.

Frequently Asked Questions

What should I do if the Battery / Charging light comes on during use?

Stop at a safe location and connect the GEX25 to its charger as soon as possible to avoid automatic shutdown.

Why is the Overload light illuminated when lifting a pallet?

The forklift’s sensors have detected that the load is too heavy or improperly placed; lower the pallet and check the weight before retrying.

How often does the Service / Hour Meter light indicate maintenance is needed?

The interval depends on usage, but typically the GEX25 requires servicing every 250 operating hours or as specified in the maintenance schedule.

Can I drive with the ABS warning light on?

You may continue operating, but braking performance may be reduced on slick surfaces; have the ABS inspected soon.

What does it mean if the Mast / Lift Limit light is on?

This means the mast has reached its maximum safe height or a limit switch is engaged; lower the forks before continuing.
