Magni Warning Lights and Symbols: Complete Guide

The Magni aerial lift (telehandler) uses a comprehensive warning system to ensure safe operation at height. Familiarize yourself with these lights to prevent overloads, hydraulic failures, or engine damage. Always refer to your Magni operator's manual for exact interpretations.

How to read the colors: Red lights indicate immediate stop conditions, amber warns of impending issues, and green/blue confirm active systems like work lights or beacon.

Magni aerial lift Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDThis red light appears when a critical fault is detected, such as engine shutdown or hydraulic pressure loss, requiring immediate action on your Magni aerial lift.Stop the lift safely, lower the boom, and turn off the engine. Consult the display for the specific fault code.
Master CautionAMBERAn amber master caution signals a non-critical issue that needs attention soon, like a pending regeneration or low fluid level on your Magni.Check the cluster for secondary warnings and plan service soon. Avoid heavy operation until resolved.
Check Engine (MIL)AMBERThis light indicates an engine performance issue, often related to emissions controls on your Magni's Deutz engine, such as a sensor fault.Have the engine diagnosed by a Magni dealer. Continued use may cause power loss.
Engine Oil PressureREDLow oil pressure can cause severe engine damage; on your Magni, this often results from low oil level or a faulty pump.Stop engine immediately. Check oil level and inspect for leaks. Do not restart until fixed.
Battery / ChargingREDIf illuminated while running, the alternator is not charging the battery, risking electrical failure on your Magni.Check alternator belt and connections. You may have limited run time before battery dies.
Coolant TemperatureREDEngine overheating is indicated; on a Magni aerial lift, this can occur during heavy lifting in hot environments.Stop and let engine idle to cool. Check coolant level and radiator for debris.
Hydraulic SystemREDThis red light warns of hydraulic system failure, such as low pressure or high temperature, critical for your Magni's boom and stabilizers.Lower boom to ground and stop. Check hydraulic oil level and temperature. Do not operate until resolved.
PParking BrakeREDIndicates the parking brake is engaged; on Magni lifts, it also flashes if the brake is not fully released when driving.Ensure brake is fully released before moving. If light stays on, brake system may need service.
Seat BeltREDThis light reminds the operator to fasten their seatbelt; on Magni aerial lifts, the machine may not operate unless buckled.Fasten seatbelt immediately. The lift will not function without it.
Glow Plug / PreheatAMBERAmber light during preheat cycle on cold starts; for Magni's Deutz diesel, wait until it turns off before cranking.Wait for light to extinguish, then start the engine. Do not crank while light is on.
DPF / RegenerationAMBERIndicates the diesel particulate filter needs regeneration; on your Magni, this can happen automatically while working or may require parked regen.Allow regen to complete. If light flashes, initiate parked regen per manual instructions.
DEF / AdBlueAMBERLow diesel exhaust fluid level; on Magni lifts, this will eventually derate power if not refilled.Add DEF/AdBlue as soon as possible. Use only approved fluid.
Water in FuelAMBERWater detected in the fuel/water separator; on your Magni, this can cause injector damage if ignored.Drain water from the separator bowl. If light persists, replace fuel filter.
Low FuelAMBERFuel level is low; on a Magni telehandler, running out can introduce air in the fuel system, requiring bleeding.Refuel as soon as possible. Do not run tank dry.
Overload / CapacityREDThe load moment indicator (LMI) detects an overload condition on your Magni aerial lift; this can cause tipping.Lower the load immediately and redistribute or reduce the load. Override is not recommended.
Swing / Slew LockGREENGreen light indicates the swing/slew lock is disengaged, allowing rotation; on Magni lifts, this is active when driving or lifting.Ensure lock is released before slewing. Green means normal operation.
Work LightsBLUEBlue light indicates the work lights are on, illuminating the work area for your Magni.No action needed. Use as needed for visibility.
Beacon / Rotating LightBLUEBlue light confirms the warning beacon is active, alerting others to your Magni's movement.Ensure beacon is on when operating in public areas. No maintenance required.

Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Radiator blocked with debris
  • Coolant fan failure

What to do

On your Magni aerial lift, immediately stop and idle engine to cool. Check coolant level and clean radiator grille. If problem persists, consult a dealer.

Hydraulic System Failure

Common causes

  • Low hydraulic oil level
  • Hydraulic hose rupture
  • Filter blockage

What to do

Lower boom and stabilizers to safe position. Check hydraulic oil level and look for leaks. Use only Magni-approved hydraulic fluid. Do not operate until repaired.

Overload Condition

Common causes

  • Exceeding rated capacity
  • Uneven load distribution
  • Operating on slope beyond limits

What to do

Slowly lower the load and redistribute. The Magni LMI will prevent further lifting. Review load chart and reposition.

Engine Low Oil Pressure

Common causes

  • Low engine oil level
  • Oil pump failure
  • Oil filter clogged

What to do

Shut down engine immediately on your Magni. Check oil level and add if low. If light remains, do not restart; call for service.

Parking Brake Malfunction

Common causes

  • Brake worn
  • Low brake fluid
  • Electrical fault

What to do

If parking brake light stays on while driving, stop safely. Check brake fluid level and inspect brakes. Have a Magni technician diagnose electrical issues.

Frequently Asked Questions

What does the flashing amber 'DPF' light mean on my Magni?

Flashing amber indicates the diesel particulate filter is nearly full and requires a stationary regeneration. Park the machine on level ground, engage parking brake, and follow the regen procedure in your manual.

Can I override the overload warning on my Magni aerial lift?

No, overriding the LMI is not recommended and may void warranty. The system is designed to prevent tip-overs. Reduce or reposition the load instead.

Why does my Magni not start when the seatbelt is unfastened?

Magni aerial lifts have a seatbelt interlock that prevents engine start if the operator is unbuckled. Fasten the seatbelt and turn the key again.

How often should I regenerate the DPF on my Magni?

Regeneration occurs automatically during normal operation. If you frequently see the regen light, you may need to perform a parked regen every 50-100 hours, depending on usage.

What type of hydraulic oil does my Magni use?

Magni recommends using a high-grade ISO 46 hydraulic oil. Always check the operator's manual or contact a dealer for the exact specification.

The 'swing lock' light stays red, what should I do?

A red swing lock light indicates the swing brake is engaged. Ensure the control is in neutral; if it persists, there may be a sensor fault. Contact Magni service.
