The Magni RTH 6.46 instrument cluster displays vital warnings for this rotating telehandler, ensuring safe operation on job sites. Red lights demand immediate shutdown, amber signals caution, and green/blue indicates active systems.
Magni RTH 6.46 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has occurred on the RTH 6.46, such as engine shutdown or hydraulic system failure. | Stop the machine immediately and investigate the primary warning message. | |
| Master Caution | AMBER | The RTH 6.46 requires operator attention for a non-critical system issue, like low fluid level or minor fault. | Check the information display for details and address within the shift. | |
| Overload / Capacity | RED | The load on the RTH 6.46 exceeds the rated capacity for the current boom angle and extension. | Immediately lower or retract the boom until the overload symbol extinguishes. | |
| Hydraulic System | AMBER | Hydraulic pressure or temperature is outside normal range for the RTH 6.46, risking performance. | Check hydraulic fluid level and inspect for leaks; reduce load if overheated. | |
| Mast / Lift Limit | AMBER | The boom or mast of the RTH 6.46 is nearing its maximum extension or angle limit. | Retract or lower the boom slightly to stay within safe envelope. | |
| Brake System | RED | A fault in the RTH 6.46 braking system, such as low brake fluid or worn pads, reduces stopping power. | Stop the machine safely and inspect brake fluid level and condition. | |
| Parking Brake | AMBER | The parking brake is engaged on the RTH 6.46; release before moving. | Disengage the parking brake before driving. | |
| Check Engine (MIL) | AMBER | The engine control module has detected a fault in the RTH 6.46’s diesel engine, such as a sensor or emissions issue. | Schedule diagnostic service soon; if flashing, reduce load and stop. | |
| Engine Oil Pressure | RED | Engine oil pressure is critically low on the RTH 6.46, risking engine damage. | Stop the engine immediately and check oil level and filter. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits on the RTH 6.46. | Stop and let engine idle to cool; check coolant level and fan operation. | |
| Battery / Charging | AMBER | The alternator is not charging the battery on the RTH 6.46, or battery voltage is low. | Check alternator belt and connections; if persists, replace battery. | |
| Low Fuel | AMBER | Fuel level in the RTH 6.46 tank is low; refuel soon to avoid air in system. | Refuel with clean diesel as soon as possible. | |
| Seat Belt | AMBER | Seat belt is not fastened on the RTH 6.46; machine operation is allowed but strongly advised. | Fasten seat belt before moving the telehandler. | |
| Work Lights | GREEN | Work lights on the RTH 6.46 are activated for improved visibility. | No action needed; switch off when not required to conserve battery. |

Most Important Warning Lights
Overload
Common causes
- Load exceeds rated capacity for boom angle
- Outriggers not properly set
- Moving with extended boom and heavy load
What to do
Immediately lower or retract the boom to reduce load. Refer to the RTH 6.46 load chart and reposition the machine if needed. Do not continue until the warning clears.
Engine Overheating
Common causes
- Low coolant level
- Blocked radiator or debris build-up
- Failed cooling fan or thermostat
What to do
Stop the engine and allow it to cool. Check coolant reservoir and add if low. Clean radiator fins from debris. If persists, inspect fan and thermostat.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic hose leak or burst
- Worn hydraulic pump
What to do
Stop the machine and check hydraulic oil sight glass. Add oil if low; do not operate if leaking. Contact service for pump or hose replacement.
Brake System Failure
Common causes
- Low brake fluid level
- Worn brake pads or discs
- Air in hydraulic brake lines
What to do
Park the RTH 6.46 on level ground and chock wheels. Check brake fluid reservoir; top up if low. If pedal feels spongy, bleed brakes or replace pads.
Frequently Asked Questions
What does the flashing red overload symbol mean on the RTH 6.46?
A flashing red overload indicates a critical overload condition—immediately retract or lower the boom to prevent tipping or structural damage.
How do I reset the service hour meter on the Magni RTH 6.46?
The service hour meter resets automatically after maintenance; if not, use the instrument cluster menu to clear it after performing required service.
Why is my amber hydraulic warning on while the machine is cold?
In cold weather, hydraulic oil may be thick, causing temporary low pressure. Warm up the engine at low RPM for 5 minutes; if light stays on, check oil level.
Can I drive the RTH 6.46 with the check engine light on?
If the light is solid, you can drive but reduce load and schedule diagnostics. If flashing, stop immediately to avoid engine damage.
Where is the DPF regeneration switch on the Magni RTH 6.46?
The DPF regen is automatic; if a manual regen is needed, use the switch located on the dashboard near the ignition key.
