| DEF / AdBlue | AMBER | DEF (AdBlue) level is low on your MRT 2550, or system fault detected. | Refill DEF tank; if light persists, have the system checked by a dealer. | |
| Water in Fuel | AMBER | Water has been detected in the fuel filter/water separator of your MRT 2550. | Drain the fuel filter/water separator immediately to prevent injector damage. | |
| Low Fuel | AMBER | Fuel level is low on your MRT 2550; refuel soon to avoid engine starvation. | Refuel the telehandler as soon as possible. | |
| High Beam | BLUE | High beam headlights are activated on your MRT 2550. | Use low beams when other vehicles are near. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or temperature is abnormal on your MRT 2550. | Check hydraulic oil level and temperature; inspect for leaks. | |
| Air Filter | AMBER | Engine air filter is restricted on your MRT 2550, reducing performance. | Replace or clean the air filter as per maintenance schedule. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter or water separator requires service on your MRT 2550. | Replace the fuel filter and drain water separator. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours on your MRT 2550. | Perform the required service as per Manitou maintenance schedule. | |
| Work Lights | GREEN | Work lights are turned on for improved visibility on your MRT 2550. | Turn off when not needed to save battery. | |
| Beacon / Rotating Light | GREEN | The yellow rotating beacon is active on your MRT 2550 for safety. | Ensure beacon is on when operating in areas with pedestrian traffic. | |
| Differential Lock | AMBER | Differential lock is engaged on your MRT 2550 for increased traction. | Disengage when on solid surfaces to avoid driveline damage. | |
| PTO Engaged | GREEN | Power take-off is engaged on your MRT 2550, e.g., for hydraulic functions. | Ensure safe operation; disengage PTO when not needed. | |
| Overload / Capacity | RED | The MRT 2550’s rated load capacity has been exceeded, risking tip-over. | Reduce the load or reposition to within safe limits immediately. | |
| Low Oil Level | RED | Engine oil level is low on your MRT 2550, risking lubrication failure. | Stop engine and add oil to the correct level. | |
| Brake Fluid Level | RED | Brake fluid level is low on your MRT 2550, which may reduce braking effectiveness. | Check for leaks and top up brake fluid; service brakes if needed. | |
| Door Open | AMBER | The cab door or rear access door is open on your MRT 2550. | Close the door securely before moving the machine. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator clogged with debris
- Faulty cooling fan or thermostat
- Hydraulic oil overheating affecting engine
What to do
Stop the MRT 2550 immediately, let the engine idle to cool, then check coolant level and radiator cleanliness. If the problem persists, contact Manitou service.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated oil (water or debris)
- Worn pump or valve seals
- Overloaded boom operation
What to do
Park the machine, lower the boom, and check hydraulic oil level and quality. Look for leaks and avoid operating until the system is serviced by a qualified technician.
Overload Condition
Common causes
- Lifting beyond rated capacity
- Load shift while moving
- Extended boom reach with heavy load
- Uneven terrain causing instability
What to do
Immediately lower the load and retract the boom. Redistribute or reduce the load to stay within the load chart. Ensure outriggers are deployed on soft ground.
Battery/Charging System Fault
Common causes
- Loose or corroded battery terminals
- Failed alternator or voltage regulator
- Broken alternator belt
- Parasitic electrical drain
What to do
Check battery connections and alternator belt tension. If the light stays on after starting, have the charging system tested by a Manitou dealer.
Transmission Over Temperature
Common causes
- Prolonged heavy load in low gears
- Low transmission fluid level
- Blocked cooler or oil lines
- Slipping clutch or torque converter
What to do
Shift to neutral and let the transmission cool at idle. Check fluid level and inspect for leaks. Avoid heavy use until the issue is resolved.
Frequently Asked Questions
Why does the overload light keep flashing even when I'm not lifting heavy loads?
On the MRT 2550, the overload sensor may be triggered by boom extension, load swing, or unstable ground. Ensure the load is within the chart for your configuration, and check that the machine is level and outriggers are set.
What should I do if the DPF regeneration light stays on for a long time?
If the light remains on, the MRT 2550 needs a parked regeneration. Park on level ground, apply parking brake, and follow the procedure in the manual (usually a button press). If it fails, contact your dealer—it may need manual cleaning.
The check engine light is on; can I still operate the telehandler?
You may continue but with caution. The MRT 2550 will likely limit engine power to protect emissions components. Check for diagnostic codes and schedule service soon to prevent further issues.
How do I know when to change the hydraulic oil on my MRT 2550?
The hour meter light or service indicator will alert you at the recommended interval (typically 500-1000 hours). Also check oil color and odor; if it smells burnt or looks milky, change it immediately.
What does it mean when the transmission temperature light comes on while operating on a slope?
The MRT 2550’s transmission works harder on inclines. The light indicates oil is too hot. Reduce load, shift to a lower gear, or stop and let it cool. Check fluid level if it happens frequently.
Why is my seatbelt light on even though I'm buckled in?
The sensor in the seat may be faulty or the buckle not fully engaged. Unbuckle and rebuckle firmly. If light persists, have the seatbelt sensor inspected by Manitou service.
