Manitou MT 625 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red stop symbol illuminates for critical faults like engine shutdown or brake failure on your MT 625, requiring immediate action. | Stop the engine safely and consult the operator's manual for the specific fault code. | |
| Master Caution | AMBER | Amber caution indicates a non-critical but important concern, such as low hydraulic oil or a clogged air filter on the MT 625. | Check the secondary warning display and address the identified system before continuing work. | |
| Check Engine (MIL) | AMBER | This amber engine symbol warns of emissions or performance issues in your MT 625's diesel engine, possibly from a faulty sensor. | Have the engine diagnosed by a Manitou dealer; you may continue at reduced power if no drivability issues. | |
| Engine Oil Pressure | RED | Red oil can means low engine oil pressure in the MT 625, risking severe engine damage if not addressed. | Stop the engine immediately, check oil level, and inspect for leaks before restarting. | |
| Battery / Charging | RED | This red battery light signals a charging system fault, like a failed alternator or loose belt in the MT 625. | Park the telehandler safely and check battery connections; if light stays on, replace the alternator. | |
| Coolant Temperature | RED | Red thermometer warns of engine overheating in your MT 625, often due to a blocked radiator or low coolant. | Stop and let the engine cool; check coolant level and radiator fins for debris. | |
| Brake System | RED | Red brake alert indicates a hydraulic brake fault, such as low fluid or worn pads on the MT 625. | Do not operate; inspect brake fluid reservoir and brake lines for leaks. | |
| Parking Brake | AMBER | Amber P symbol shows the parking brake is engaged; it should be off before driving your MT 625. | Release the parking brake before moving; if light stays on, check the brake switch. | |
| Seat Belt | RED | Red seat belt icon warns the operator's belt is unbuckled; the MT 625 requires it for safe operation. | Fasten your seat belt immediately to continue operation. | |
| Glow Plug / Preheat | AMBER | Amber coil indicates glow plugs are heating for cold starts; wait for it to turn off before cranking the MT 625. | Turn the key to preheat position and wait until the light extinguishes, then start the engine. | |
| Low Fuel | AMBER | Amber fuel pump warns of low diesel level in the MT 625's tank; refuel soon to avoid air in the system. | Add diesel fuel; do not run completely dry to prevent injection pump damage. | |
| High Beam | BLUE | Blue headlight symbol shows the high beams are active on your MT 625 for better visibility in low light. | Use high beams only when no oncoming traffic; dim when needed. | |
| Hydraulic System | RED | Red hydraulic symbol indicates a system fault, such as low oil or a filter blockage in the MT 625's hydraulics. | Stop machine; check hydraulic oil level and inspect for leaks. | |
| Reduced Power (Limp Mode) | AMBER | Amber turtle/tortoise indicates the MT 625's ECU has limited engine power to prevent damage from an underlying issue. | Drive carefully to a safe area and diagnose the fault with a scanner. | |
| Hydraulic Oil | AMBER | Amber oil can with drip warns of low hydraulic oil level in the MT 625, affecting lift and steering performance. | Check hydraulic reservoir and add correct oil type as specified in the manual. | |
| Air Filter | AMBER | Amber filter icon signals a clogged engine air filter on the MT 625, reducing power and fuel efficiency. | Inspect and replace the air filter element if necessary; check restriction gauge. | |
| Service / Hour Meter | AMBER | Amber wrench indicates scheduled maintenance is due based on engine hours for the MT 625. | Perform the recommended service as per the maintenance schedule in the operator's manual. | |
| Work Lights | GREEN | Green light symbol confirms the work lights are turned on for nighttime or low-visibility jobs with the MT 625. | Use as needed; turn off when not required to save battery. | |
| Beacon / Rotating Light | GREEN | Green beacon symbol shows the rotating warning light is active on the MT 625 for site safety. | Ensure beacon is on when operating in areas with pedestrian traffic. | |
| Differential Lock | AMBER | Amber diff lock icon indicates the differential is engaged for better traction on slippery ground in the MT 625. | Disengage on hard surfaces to prevent driveline damage. | |
| Overload / Capacity | RED | Red overload warning flashes if the MT 625's load exceeds rated capacity, risking instability. | Immediately lower the load and reposition to reduce moment; check load chart. | |
| Low Oil Level | AMBER | Amber oil level warning indicates the engine oil is low in the MT 625; add oil soon. | Check dipstick and top up with recommended oil grade. | |
| Brake Fluid Level | RED | Red brake fluid icon warns of low fluid in the hydraulic braking system of the MT 625. | Stop and check reservoir; fill to max line; inspect for leaks. | |
| Door Open | RED | Red door symbol alerts that the cab door is not fully closed on the MT 625, a safety hazard. | Close the door securely before moving the machine. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Blocked radiator fins with debris
- Faulty thermostat or water pump
What to do
Stop the MT 625 immediately, let the engine cool, then check coolant level and clean the radiator. If recurring, replace the thermostat or water pump.
Brake System Failure
Common causes
- Low brake fluid due to leaks
- Worn brake pads or shoes
- Air in hydraulic brake lines
What to do
Do not operate; inspect brake lines and reservoir. Bleed the system or replace pads as needed. Contact Manitou service for hydraulic brake issues.
Overload Condition
Common causes
- Exceeding rated load capacity on the forks
- Load too far forward on forks
- Operating on a slope with heavy load
What to do
Immediately lower the load and reposition. Refer to the load chart for the MT 625's rated capacity and ensure the load center is within limits.
Hydraulic System Malfunction
Common causes
- Low hydraulic oil level
- Contaminated or old hydraulic fluid
- Clogged hydraulic filter
What to do
Check hydraulic reservoir and add correct fluid; replace filter if past service interval. Look for leaks in hoses and cylinders.
Low Engine Oil Pressure
Common causes
- Low oil level or dirty oil
- Oil pump failure
- Worn engine bearings
What to do
Stop engine immediately; check oil level and add if low. If light persists, have the oil pump and pressure sensor inspected by a technician.
Frequently Asked Questions
What should I do if the red master warning light comes on while operating my MT 625?
Stop the telehandler safely as soon as possible, shut off the engine, and refer to the fault code in the instrument cluster. Do not restart until the issue is resolved, as it indicates a critical failure.
Why is the amber check engine light on and can I continue working?
The amber check engine light on your MT 625 indicates an emissions or sensor issue. You may continue at reduced power, but have it diagnosed soon to avoid performance loss or further damage.
How do I reset the service hour meter light on my MT 625?
The service light is reset by a dealer after performing the required maintenance. Attempting to reset it yourself may not clear the code unless the service interval is properly completed.
What does the overload warning mean and how do I avoid it?
The overload warning means you have exceeded the MT 625's load capacity or reach limits. Check the load chart and reposition the load closer to the machine. Always respect rated capacities to prevent tipping.
Can I drive with the amber differential lock light on?
No, the diff lock should only be engaged on loose or slippery surfaces. Driving on hard pavement with it engaged can damage the drivetrain. Disengage it as soon as traction improves.
Why does my battery light come on intermittently?
Intermittent battery light on the MT 625 often indicates a loose alternator belt or a failing alternator. Check the belt tension and connections; if the light persists, the alternator may need replacement.
