| Fasten Seat Belt | RED | Operator must fasten seat belt on the RTH 5.25 before operating. | Fasten the seat belt; the interlock may prevent movement until done. | |
| Reduced Power (Limp Mode) | AMBER | Engine power is limited to protect components on the RTH 5.25. | Reduce load; drive at low speed to a safe location for service. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature is high or level low on the RTH 5.25. | Check oil level and temperature; allow system to cool if hot. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is above normal operating range on the RTH 5.25. | Reduce engine load; if persists, stop and inspect oil level and cooling system. | |
| Air Filter | AMBER | Air intake filter is clogged on the RTH 5.25, restricting airflow. | Clean or replace the air filter element. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter requires maintenance on the RTH 5.25. | Replace the fuel filter and drain water separator. | |
| Service / Hour Meter | AMBER | Scheduled maintenance interval reached on the RTH 5.25. | Refer to operator's manual for required service. | |
| Work Lights | GREEN | Work lights are activated on the RTH 5.25. | No action needed unless desired. | |
| Beacon / Rotating Light | GREEN | Warning beacon is active on the RTH 5.25. | Ensure beacon is working for visibility. | |
| Swing / Slew Lock | AMBER | Swing lock is engaged on the RTH 5.25, preventing rotation. | Release swing lock before operating boom rotation. | |
| Differential Lock | AMBER | Differential lock is engaged on the RTH 5.25 for traction. | Engage only on slippery surfaces; disengage for normal driving. | |
| Overload / Capacity | RED | Load on the RTH 5.25 exceeds rated capacity. | Reduce load immediately and reposition if necessary. | |
| Low Oil Level | AMBER | Engine oil level is low on the RTH 5.25. | Add oil to the correct level. | |
| Brake Fluid Level | RED | Brake fluid level is low on the RTH 5.25. | Check for leaks and add DOT 4 brake fluid; service brakes if necessary. | |
| Door Open | AMBER | Cab door is open on the RTH 5.25. | Close door securely before moving. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust temperature is high on the RTH 5.25, often during DPF regeneration. | Avoid parking near dry grass or combustibles. | |
| Washer Fluid Low | AMBER | Windshield washer fluid level is low on the RTH 5.25. | Top up washer fluid. |

Most Important Warning Lights
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated or overheated oil
- Faulty pump or relief valve
What to do
Stop the RTH 5.25 immediately, check hydraulic oil level and cleanliness, inspect for leaks, and top up with Magni-recommended oil. If light persists, contact a Magni service center.
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Malfunctioning thermostat or fan
What to do
Let the engine idle for 5 minutes on the RTH 5.25, then shut off. Check coolant level and add 50/50 mix if low. Clean radiator with compressed air; if issue recurs, service the cooling system.
Brake System Fault
Common causes
- Brake fluid leak
- Worn brake pads
- Air in brake lines
What to do
Park the RTH 5.25 on level ground and apply parking brake. Check brake fluid reservoir and add DOT 4 fluid. If light stays on, do not operate until brakes are bled or serviced.
Transmission Over-Temperature
Common causes
- Overloading the telehandler
- Low transmission fluid level
- Clogged transmission cooler
What to do
Reduce load and shift to a lower gear on the RTH 5.25. Allow transmission to cool at idle. Check fluid level with engine running; top up with Dexron VI. Clean cooler fins if needed.
Overload Condition
Common causes
- Exceeding rated load capacity
- Uneven load distribution
- Using boom at too high an angle
What to do
Immediately lower the load and reposition it on the RTH 5.25. Refer to load chart; never exceed limits. The overload warning will sound continuously until corrected.
Frequently Asked Questions
What does the Master Warning light mean on my Magni RTH 5.25?
The red Master Warning light signals a critical fault that requires immediate engine shutdown and attention, such as a hydraulic system failure or engine overspeed.
Can I operate the RTH 5.25 with the amber Master Caution light on?
Yes, but only briefly and with caution. The amber light indicates a non-critical issue; check the display for the specific warning and have it serviced as soon as possible.
My DPF regeneration light stays on for a long time. What should I do?
On the RTH 5.25, DPF regeneration typically lasts 20-30 minutes. If it persists, ensure the engine is at operating temperature and drive at moderate load. If light remains, consult a dealer for forced regeneration.
What does the swing lock indicator mean?
The amber swing lock light indicates the boom rotation lock is engaged on the RTH 5.25. Release it from the cab before slewing to avoid damage.
How do I reset the service hour meter on my RTH 5.25?
The service hour meter warning cannot be reset by the operator; it indicates that scheduled maintenance is due. Perform the required service, then a technician must reset it using the diagnostic tool.
What should I do if the hydraulic oil temperature warning lights up?
Reduce the workload and allow the hydraulics to cool by running at idle. Check oil level and cleanliness on the RTH 5.25; if the light persists, inspect the oil cooler for obstruction.
