Claas AXION 800 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | On the AXION 800, this red stop sign indicates a critical system fault requiring immediate engine shutdown. | Stop the tractor safely and check the display for the associated warning code. | |
| Master Caution | AMBER | An amber caution symbol in your AXION 800 signals a non-critical but attention-worthy condition from another system. | Refer to the information display for the specific alerting system and take appropriate action. | |
| Check Engine (MIL) | AMBER | This amber engine symbol on the AXION 800 indicates a fault in the engine management or emission control system. | Have the engine diagnostics checked by a Claas dealer as soon as possible to avoid performance loss. | |
| Engine Oil Pressure | RED | If this red oil can appears while the engine is running, the AXION 800 has dangerously low oil pressure. | Immediately stop the engine and check oil level; do not restart until the issue is resolved. | |
| Battery / Charging | RED | This red battery indicates a charging system failure on your AXION 800, such as a faulty alternator or broken belt. | Stop the engine and inspect the alternator belt and connections; contact a technician if needed. | |
| Coolant Temperature | RED | A red thermometer shows the AXION 800 engine coolant is overheating, risking severe damage. | Reduce load immediately, let the engine idle, and check coolant level after cooling. | |
| Transmission Temp | AMBER | An amber transmission icon warns that the AXION 800's gearbox oil is running hot, often under heavy load. | Shift to a lower gear or reduce engine speed to allow the transmission to cool. | |
| Brake System | RED | This red brake circle indicates a fault in the AXION 800's service brake system, such as low fluid or wear. | Do not operate; check brake fluid level and have the system inspected immediately. | |
| Parking Brake | RED | The red (P) symbol reminds you the AXION 800 parking brake is engaged; it may also flash if a fault exists. | Release the parking brake before moving; if flashing, check the brake system for issues. | |
| Glow Plug / Preheat | AMBER | An amber coil indicates the AXION 800's glow plugs are preheating the intake air for cold starts. | Wait for the light to go out before cranking the engine. | |
| DPF / Regeneration | AMBER | This amber filter icon signals that the AXION 800's diesel particulate filter is performing a regeneration cycle. | Keep the engine running at operating temperature until the light turns off; do not interrupt. | |
| DEF / AdBlue | AMBER | An amber DEF symbol warns that the AXION 800's AdBlue level is low or the system has a fault. | Refill AdBlue soon; if the light stays on after refill, consult your Claas dealer. | |
| Air Filter | AMBER | An amber air filter icon means the AXION 800's engine air intake is restricted and needs service. | Clean or replace the air filter to prevent power loss and increased fuel consumption. | |
| Hydraulic Oil | AMBER | This amber oil can with a drop indicates low hydraulic oil level or a system fault on the AXION 800. | Check hydraulic fluid level and top up if necessary; inspect for leaks. | |
| PTO Engaged | AMBER | An amber PTO symbol shows the power take-off is engaged on your AXION 800. | Disengage PTO before working near the driveline or entering the cab. | |
| Differential Lock | AMBER | An amber differential icon indicates the AXION 800's diff lock is active, providing increased traction. | Disengage on firm ground to avoid driveline damage. | |
| Service / Hour Meter | AMBER | An amber wrench symbol reminds you that scheduled maintenance is due on your AXION 800. | Refer to the operator's manual and perform the required service promptly. | |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator or fan drive
- Faulty thermostat or water pump
What to do
For the AXION 800, stop the engine immediately, allow it to cool, then check coolant level and clean the radiator fins. If recurring, have the cooling system tested by a Claas technician.
Low Oil Pressure
Common causes
- Insufficient engine oil level
- Oil pump failure or worn bearings
- Oil viscosity too thin or wrong grade
What to do
On your AXION 800, shut down the engine and verify oil level with the dipstick. If level is correct but light remains, do not restart—contact Claas dealer for internal inspection.
Hydraulic System Failure
Common causes
- Low hydraulic oil level or leak
- Clogged hydraulic filter
- Faulty hydraulic pump or relief valve
What to do
Check hydraulic fluid sight glass on the AXION 800; top up with recommended oil. Inspect hoses and cylinders for leaks. If system pressure is low, replace filters and seek dealer assistance.
Transmission Overheating
Common causes
- Continuous heavy load or high ambient temperature
- Low transmission oil level
- Clogged oil cooler or faulty fan
What to do
For the AXION 800, reduce engine load and shift to a lower gear. Check transmission oil level and allow the cooler to ventilate. If light persists, clean the cooler and consult Claas service.
Brake System Malfunction
Common causes
- Low brake fluid level
- Worn brake pads or shoes
- Leak in brake lines or caliper
What to do
On your AXION 800, check brake fluid reservoir under the hood. If low, fill with DOT 4 fluid and inspect for leaks. Do not operate; have brakes serviced by a qualified technician.
Frequently Asked Questions
Why does my AXION 800 show a red stop light but no other warnings?
The red master warning may illuminate for a critical system fault not listed individually. Always check the on-board display for the specific error code, then refer to your operator's manual or call Claas support.
How do I start a regeneration manually on the AXION 800?
The AXION 800 can initiate parked regeneration via the display menu under 'DPF Regen'. Ensure the tractor is parked, PTO off, engine at operating temperature, and follow on-screen prompts.
The amber caution light stays on while driving—is it safe?
An amber caution on the AXION 800 means a non-critical issue. You can continue driving but should check the display to identify the cause (e.g., low AdBlue, service reminder) and address it soon.
What does it mean if the hydraulic oil light comes on intermittently?
Intermittent hydraulic oil warnings on the AXION 800 often indicate a low fluid level during heavy use or a slight leak. Check fluid level when cold and inspect hoses for weeping; if persistent, have system pressure tested.
My glow plug light flashes then goes out—should I wait?
If the glow plug light flashes briefly, it may be a self-test. On the AXION 800, wait until the light turns off solid before cranking. If it stays off, start normally. Consult manual if flashing persists.
Can I clear the service reminder myself on the AXION 800?
Yes, after performing the required maintenance, you can reset the service interval via the instrument cluster menu or with a diagnostic tool. Follow the steps in your operator's manual to avoid false reminders.
