Magni RTH 7.26 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | On the Magni RTH 7.26, a red master warning indicates a critical system failure that requires you to safely stop the machine and consult the manual. | Immediately stop all operations, lower the load, and shut off the engine. Do not restart until the fault is resolved. | |
| Master Caution | AMBER | An amber caution light on the RTH 7.26 signals a non-critical but important system alert that needs attention soon. | Check the display for additional codes and plan to service the machine as soon as possible. | |
| Check Engine (MIL) | AMBER | This light indicates an engine management fault on the Magni RTH 7.26 that may affect emissions or performance. | Have the engine diagnosed with a scan tool; continued operation may reduce power or damage components. | |
| Engine Oil Pressure | RED | Low oil pressure can cause severe engine damage in the Magni RTH 7.26; often due to low oil level or pump failure. | Shut down the engine immediately and check oil level. Do not restart until pressure is restored. | |
| Battery / Charging | RED | The Magni RTH 7.26's charging system is not functioning, which will quickly drain the battery and cause electrical failures. | Check alternator belt and battery connections. If light stays on, service charging system before further use. | |
| Coolant Temperature | RED | Engine coolant temperature is too high on the RTH 7.26, risking overheating and engine damage. | Stop the engine, let it cool, and check coolant level. Inspect for leaks or fan issues. | |
| Transmission Temp | AMBER | Transmission oil temperature is elevated on the Magni RTH 7.26; heavy usage or low fluid may be the cause. | Reduce load and allow the transmission to cool. Check fluid level and condition. | |
| Brake System | RED | A fault in the brake system of the RTH 7.26 has been detected, which could compromise stopping ability. | Do not operate the machine. Have brakes inspected immediately by a qualified technician. | |
| Parking Brake | GREEN | The parking brake on the Magni RTH 7.26 is engaged, which prevents the machine from moving. | Release the parking brake before driving. If it stays on once released, service the system. | |
| Glow Plug / Preheat | AMBER | The glow plugs are heating in the RTH 7.26's diesel engine; wait for the light to turn off before starting. | Turn the key to the preheat position and wait until the light extinguishes. Then crank the engine. | |
| Water in Fuel | AMBER | Water has accumulated in the fuel filter/water separator on the Magni RTH 7.26, which can damage injectors. | Drain the water from the separator as soon as possible. Check for contaminated fuel. | |
| Low Fuel | AMBER | The fuel level in the RTH 7.26 is low, risking engine shutdown if not refueled soon. | Refuel with clean diesel as soon as possible to avoid air in the system. | |
| Hydraulic System | RED | A hydraulic system fault on the Magni RTH 7.26 may affect lifting and steering functions. | Stop all operations and check hydraulic oil level and for leaks. Do not use if light remains on. | |
| Overload / Capacity | RED | The load on the Magni RTH 7.26 exceeds the rated capacity or load chart area, risking instability. | Immediately lower the load and reduce weight or reposition. Check load chart and retry. | |
| Seat Belt | GREEN | Indicates that the seat belt on the RTH 7.26 is fastened, which is required for operation. | Ensure belt is properly fastened before driving. If light stays off when buckled, check sensor. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Blocked radiator or debris in cooling fins
- Faulty cooling fan or thermostat
What to do
On the Magni RTH 7.26, stop the engine and allow it to cool. Check coolant reservoir and add proper mixture. Clean radiator fins and ensure fan belt is intact. If issue persists, inspect thermostat and fan clutch.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated oil (water or debris)
- Leaking hose or cylinder seal
What to do
For the RTH 7.26, visually inspect hydraulic hoses and cylinders for leaks. Check oil level and top up with Magni-approved fluid. Change hydraulic filter if oil is dirty. Do not operate until system is sealed.
Overload Condition
Common causes
- Load exceeds maximum capacity
- Improper load placement (far from boom pivot)
- Operating on a slope beyond rating
What to do
Immediately lower the load and retract boom. Refer to the Magni RTH 7.26 load chart for the current configuration. Reposition the machine on level ground and select a smaller load or extend outriggers.
Brake System Warning
Common causes
- Low brake fluid level
- Worn brake pads or linings
- Air in hydraulic brake circuit
What to do
On the Magni RTH 7.26, check brake fluid reservoir and top off with DOT 4 fluid. Inspect brake pads for wear. If pedal feels spongy, bleed the brakes. Do not operate until brakes are certified safe.
Engine Low Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure or pickup blockage
- Excessive oil contamination or thinning
What to do
Stop the engine on the RTH 7.26 immediately. Check oil level using dipstick and add approved viscosity oil. If level is normal, do not restart; have oil pressure tested by a technician. Towing may be required.
Frequently Asked Questions
What does the red master warning light mean on my Magni RTH 7.26?
It signals a critical system failure that requires you to stop the machine immediately, lower the load, and shut down the engine. Do not operate until the specific fault is resolved.
How do I reset the service interval indicator?
On the RTH 7.26, the service reminder can usually be reset through the dashboard menu: navigate to 'Service' and follow prompts, or consult the operator's manual for specific button sequence. It may require entering a code.
Why is the hydraulic caution light on while operating?
The amber hydraulic light on your Magni RTH 7.26 indicates a potential issue like low oil level, high temperature, or filter restriction. Check the hydraulic oil level and temperature gauge. If light persists, inspect for leaks or contaminated oil.
Can I continue to use the telehandler if the glow plug light stays on?
No. If the glow plug indicator remains on after starting, the preheat system may be faulty. Continued operation may cause hard starting. Have the glow plugs and relay inspected by a dealer.
What does the overload alarm sound mean?
The overload alarm on the RTH 7.26 warns that the load is exceeding the rated capacity for the current boom angle and extension. Immediately lower the load and reposition to a safer configuration. Check the load chart.
How often should I check the water-in-fuel separator?
For the Magni RTH 7.26, drain the fuel/water separator daily or every 10 hours of operation, especially in humid conditions. If the water-in-fuel light comes on, drain immediately to prevent injector damage.
