Linde H25 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault has been detected by the Linde H25's onboard diagnostics, requiring an immediate stop. | Safely park the forklift and switch off the engine; contact service support before further use. | |
| Check Engine (MIL) | AMBER | The engine control unit has registered a malfunction specific to the H25's fuel or emission systems. | Schedule a diagnostic check with a Linde technician as soon as possible. | |
| Engine Oil Pressure | RED | The engine oil pressure has dropped below safe levels, risking severe engine damage in the H25. | Shut down the engine immediately and check oil level; do not restart until resolved. | |
| Battery / Charging | RED | The alternator is not charging the battery, which can quickly drain power on the H25. | Inspect the alternator belt and connections; avoid shutting off the engine until issue is resolved. | |
| Coolant Temperature | RED | Engine coolant temperature is dangerously high, risking overheating and damage to the H25's engine. | Stop the forklift, allow the engine to cool, and check coolant level before proceeding. | |
| Brake System | RED | A malfunction in the H25's braking system has been detected, compromising stopping ability. | Do not continue operation; arrange for immediate inspection and repair. | |
| Parking Brake | RED | The parking brake is engaged, preventing the H25 from moving. | Release the parking brake before attempting to drive. | |
| Low Fuel | AMBER | The fuel level in the H25's tank is approaching empty, which can cause stalling. | Refuel at the next opportunity to avoid work interruption. | |
| Glow Plug / Preheat | AMBER | The engine preheat system is active, aiding cold starts on the H25's diesel engine. | Wait for the indicator to turn off before starting the engine. | |
| DPF / Regeneration | AMBER | The diesel particulate filter requires regeneration to clear soot buildup in the H25. | Follow the H25's regeneration procedure as outlined in the operator's manual. | |
| DEF / AdBlue | AMBER | The AdBlue/DEF tank is low, which is essential for emissions control on the H25. | Top up the DEF tank promptly to avoid power reduction or engine shutdown. | |
| Water in Fuel | AMBER | Water contamination has been detected in the H25's fuel system. | Drain the water separator before further operation. | |
| Hydraulic System | AMBER | The hydraulic system has detected a pressure or fluid level issue on the H25. | Inspect hydraulic fluid level and check for leaks or malfunctions. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or temperature is out of range, affecting lift performance on the H25. | Check oil level and allow system to cool if overheated. | |
| Air Filter | AMBER | The air filter is clogged, reducing engine efficiency on the H25. | Replace or clean the air filter to restore performance. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or water separator is full on the H25. | Replace the filter and drain any accumulated water. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours logged by the H25. | Arrange for service according to the maintenance schedule. | |
| Work Lights | GREEN | The H25's work lights are currently switched on for better visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The warning beacon is active, signaling forklift operation in the area. | Verify beacon is functioning in required zones. | |
| Overload / Capacity | RED | The H25 is attempting to lift a load that exceeds its rated capacity, risking tip-over. | Lower the load immediately and re-evaluate load weight. | |
| Seat Belt | RED | The operator's seat belt is not fastened, disabling safe operation on the H25. | Secure the seat belt before driving. | |
| Fasten Seat Belt | RED | The H25 detects the seat is occupied but the belt is not fastened. | Buckle the seat belt to clear the warning. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Blocked oil filter
What to do
For the Linde H25, immediately check the engine oil level and top up if needed. If the warning persists, arrange for a qualified technician to inspect the oil pump and filter.
Coolant Temperature
Common causes
- Coolant leak
- Faulty thermostat
- Radiator blockage
What to do
Stop the H25 and allow the engine to cool down. Inspect for visible leaks or low coolant, and have the cooling system checked if overheating continues.
Overload / Capacity
Common causes
- Attempting to lift excessive weight
- Incorrect load center
- Load positioned too far forward
What to do
Lower the load immediately and verify it does not exceed the H25's rated capacity. Adjust load placement and ensure proper technique before continuing.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads
- Hydraulic failure
What to do
Cease operation and inspect brake fluid and visible components. Do not use the H25 until repairs are completed by a certified technician.
Battery / Charging
Common causes
- Broken alternator belt
- Faulty alternator
- Loose battery terminals
What to do
Check the alternator belt and battery connections on the H25. If the issue is not obvious, have the charging system tested by a service professional.
Frequently Asked Questions
What should I do if the DPF regeneration light comes on in my Linde H25?
Follow the regeneration process as described in your H25 operator's manual; this may involve running the engine at higher RPMs or parking for a stationary regen.
Why does my H25 show the hydraulic warning light?
This indicates a hydraulic fluid level or pressure issue; check for leaks and top up fluid if necessary.
How often does the H25 require scheduled maintenance?
Service intervals depend on engine hours; check the hour meter and follow the maintenance schedule in your H25 manual.
Can I continue operating if the check engine light is on?
You may continue short-term if no other symptoms are present, but arrange for diagnostic service soon to prevent further issues.
What does it mean when the DEF/AdBlue light is illuminated?
The DEF/AdBlue tank is low; refill as soon as possible to avoid reduced engine power or shutdown.
Is it safe to operate the H25 with the air filter warning light on?
Prolonged operation with a clogged air filter can reduce performance and damage the engine; clean or replace the filter promptly.
