| Battery / Charging | RED | The H30 is not charging properly or battery voltage is critically low. | Inspect alternator belt and battery connections before restarting. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe levels, risking overheating. | Stop the forklift, allow engine to cool, and check coolant level. | |
| Brake System | RED | A brake system malfunction has been detected, which could affect stopping ability. | Do not operate the H30 until brakes are inspected and repaired. | |
| ABS | AMBER | The anti-lock braking function is inactive due to a detected fault. | Drive cautiously and arrange for ABS diagnosis soon. | |
| Parking Brake | RED | The parking brake on the H30 is engaged or not fully released. | Release the parking brake before moving. | |
| Seat Belt | AMBER | The seat belt is not fastened while the H30 is powered on. | Fasten your seat belt before operating. | |
| Glow Plug / Preheat | AMBER | Engine preheating is active to aid cold starting in the H30’s diesel engine. | Wait for the light to turn off before starting the engine. | |
| DPF / Regeneration | AMBER | The diesel particulate filter is regenerating or requires regeneration soon. | Allow the regeneration cycle to complete or initiate parked regen as instructed. | |
| DEF / AdBlue | AMBER | DEF/AdBlue fluid level is low or there is a system fault, affecting emissions control. | Refill DEF/AdBlue tank and check for leaks. | |
| Water in Fuel | AMBER | Water has accumulated in the H30’s fuel filter, risking injector damage. | Drain the water separator promptly. | |
| Low Fuel | AMBER | The fuel level is approaching empty, risking engine shutdown. | Refuel at the next opportunity. | |
| High Beam | BLUE | The headlamp high beams are activated for improved visibility. | Switch off if not needed to avoid dazzling others. | |
| Hydraulic System | AMBER | A hydraulic system fault or low hydraulic fluid has been detected. | Inspect hydraulic fluid level and check for leaks. | |
| Reduced Power (Limp Mode) | AMBER | The engine has entered limp mode to protect itself from damage. | Operate at reduced speed and arrange for service. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature is high or level is low in the H30. | Let the system cool and check oil level. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is above normal operating range. | Pause operation and allow engine to cool. | |
| Air Filter | AMBER | The air filter is clogged, reducing engine performance. | Replace or clean the air filter. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter is restricted or water separator needs draining. | Service the fuel filter and drain water. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours. | Arrange for required service as indicated. | |
| Work Lights | GREEN | Work lights are switched on for improved area illumination. | Turn off when not needed. | |
| Beacon / Rotating Light | AMBER | The beacon is active to warn nearby personnel of forklift operation. | Ensure beacon is functional in active zones. | |
| Overload / Capacity | RED | The H30’s load exceeds safe lifting capacity, risking tip-over. | Lower the load immediately and reduce weight. | |
| Brake Fluid Level | RED | Brake fluid is below minimum safe level, compromising braking performance. | Do not use the forklift until brake fluid is topped up and leaks checked. | |
| Door Open | AMBER | A cab door is not fully closed while the H30 is powered on. | Secure all doors before operation. | |
| Washer Fluid Low | AMBER | Windshield washer fluid is low. | Refill washer fluid reservoir. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Blocked oil filter
What to do
Stop the H30 engine, check oil level, and inspect for leaks or filter blockages before restarting. Seek Linde service if pressure does not recover.
Coolant Temperature
Common causes
- Low coolant
- Faulty thermostat
- Radiator blockage
What to do
Turn off the engine and allow it to cool, then inspect coolant level and radiator. Top up coolant and clear obstructions; contact Linde support if overheating persists.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads
- Hydraulic failure
What to do
Inspect the H30’s brake fluid reservoir and lines for leaks, and check pad wear. Do not resume operation until repairs are made.
Overload / Capacity
Common causes
- Attempting to lift excessive weight
- Incorrect load positioning
- Faulty load sensor
What to do
Lower the load immediately, verify the load chart, and ensure weight is within the H30’s rated capacity. Service the sensor if warning persists.
Battery / Charging
Common causes
- Loose alternator belt
- Battery failure
- Faulty alternator
What to do
Check the alternator belt tension and battery terminals on the H30. Replace faulty parts as needed to restore charging function.
Frequently Asked Questions
What should I do if the DPF regeneration light stays on in my H30?
If the DPF light remains illuminated, follow the regeneration procedure in your operator’s manual or contact Linde service for assistance.
Can I operate the H30 if the ABS light is on?
You may operate the forklift, but braking performance could be affected, so drive cautiously and schedule a repair.
How often should I check hydraulic oil on the H30?
Check hydraulic oil levels daily before operation to prevent system damage and maintain lift performance.
Why does the seat belt light stay on even when buckled?
The seat belt sensor or wiring may be faulty; have it inspected to ensure compliance with safety regulations.
What does it mean if the overload warning appears with a light load?
This could indicate a malfunction in the load sensor—have it calibrated or repaired by a qualified technician.
