| Check Engine (MIL) | AMBER | The GEX30’s controller has detected an engine or drive system issue that could impact operation. | Note any performance changes and arrange for a technician to diagnose the fault. | |
| Battery / Charging | RED | The traction battery voltage is critically low or the charging system is malfunctioning on the GEX30. | Stop operation and recharge or inspect the battery system. | |
| Brake System | RED | A malfunction or low fluid level in the GEX30's hydraulic brake system has been detected. | Do not continue driving; inspect the brakes and repair before use. | |
| ABS | AMBER | The Anti-lock Braking System is not functioning properly on the GEX30. | Drive cautiously and have the ABS checked at the next opportunity. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the GEX30. | Release the parking brake before attempting to move. | |
| Seat Belt | AMBER | The operator’s seat belt is not fastened while the GEX30 is powered on. | Securely fasten the seat belt before operating. | |
| Low Fuel | AMBER | The GEX30’s battery charge is approaching minimum safe levels for operation. | Plan to recharge the battery soon to avoid downtime. | |
| Hydraulic System | AMBER | A hydraulic system fault or low fluid is affecting lift or tilt functions on the GEX30. | Inspect hydraulic fluid level and check for leaks or malfunctions. | |
| Service / Hour Meter | AMBER | The GEX30 has reached a scheduled service interval based on operating hours. | Arrange for routine maintenance as indicated in the service schedule. | |
| Work Lights | BLUE | The GEX30’s work lights are currently switched on for enhanced visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The warning beacon is active, signaling the GEX30 is in operation. | Ensure beacon is functioning in busy areas for safety. | |
| Overload / Capacity | RED | The GEX30’s load exceeds its rated capacity and may trigger safety interlocks. | Lower the load immediately and verify weight before proceeding. | |
| Battery Discharge (BDI) | AMBER | The battery discharge indicator shows the GEX30’s battery is nearing full depletion. | Recharge the battery soon to avoid automatic shutdown. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum lift height or a limit switch has been activated on the GEX30. | Do not attempt to lift further; lower or reposition the load. |

Most Important Warning Lights
Battery / Charging
Common causes
- Traction battery near empty
- Charger malfunction
- Loose or corroded battery terminals
What to do
Stop using the GEX30 and connect to a charger. Inspect battery connections and ensure the charger is operating correctly.
Brake System
Common causes
- Low hydraulic brake fluid
- Brake line leak
- Worn brake pads or components
What to do
Check the brake fluid reservoir and top up if low. Inspect for leaks or worn parts and repair before returning to service.
Overload / Capacity
Common causes
- Load exceeds rated forklift capacity
- Incorrect load positioning
- Faulty load sensor
What to do
Remove excess weight and ensure the load is within the GEX30’s rated capacity. If warning persists, have the load sensor checked.
Hydraulic System
Common causes
- Low hydraulic fluid level
- Hydraulic leak
- Pump or valve malfunction
What to do
Inspect and refill hydraulic fluid as needed. Examine hoses and fittings for leaks, and service the hydraulic pump or valves if necessary.
Master Warning (Stop)
Common causes
- Major electrical fault
- Critical system failure
- Severe overheating
What to do
Immediately stop the GEX30, switch off the power, and contact a Clark service technician to diagnose the fault.
Frequently Asked Questions
What should I do if the battery discharge indicator lights up during a shift?
Plan to finish your current task and drive the GEX30 to a charging station as soon as possible to prevent an automatic shutdown.
Why does the overload light come on even when the load seems within limits?
Check that the load is properly centered and not exceeding the rated capacity; if the warning persists, the load sensor may need calibration.
Can I continue operating if only the master caution light is on?
You may continue working for a short period, but review the display for details and schedule maintenance without delay.
How often should I service the hydraulic system?
Follow the Clark GEX30 maintenance schedule, but always check fluid levels and inspect for leaks before each shift.
What does it mean when the mast limit light is illuminated?
This means the mast has reached its maximum height or a safety limit; lower the mast before continuing.
