Snorkel 400S Warning Light Symbols and What They Mean

The Snorkel 400S telehandler instrument cluster provides essential operational feedback to ensure safe and efficient material handling. Designed for rough terrain, it monitors critical systems including engine, hydraulics, and load capacity, with intuitive warning lights and gauges.

How to read the colors: Red indicates immediate stop and fix; amber signals caution and prompt attention; green/blue confirms normal operation or active functions.

Snorkel 400S Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDA critical system fault requires immediate shutdown to prevent damage or injury.Stop the engine and consult the operator's manual for fault codes.
Master CautionAMBERA non-critical fault is present but does not require immediate shutdown.Check the display for additional warning lights and address as needed.
Check Engine (MIL)AMBEREngine management has detected a fault that may affect emissions or performance.Service the engine and clear the code with a diagnostic tool.
Engine Oil PressureREDOil pressure is below safe level, risking engine damage.Stop engine immediately, check oil level and for leaks.
Battery / ChargingREDCharging system voltage is out of range, battery not charging properly.Check alternator belt, connections, and battery condition.
Coolant TemperatureREDEngine coolant is overheating, can cause engine failure.Stop engine, let cool, check coolant level and fan operation.
Hydraulic SystemAMBERHydraulic system temperature or pressure is above normal range.Reduce load and allow system to cool; check hydraulic oil level.
PParking BrakeREDParking brake is engaged or fault detected; do not operate unless confirmed.Release parking brake; if light remains, service brake system.
Fasten Seat BeltREDOperator seat belt is not fastened; machine operation restricted.Fasten seat belt to enable machine functions.
High BeamBLUEHigh beam headlights are activated for enhanced visibility.No action needed; switch to low beam when approaching other vehicles.
Work LightsGREENWork lights are on for low-light conditions.No action unless desired to turn off.
Overload / CapacityREDLoad exceeds maximum rated capacity; stability at risk.Reduce load immediately to prevent tipping.
Service / Hour MeterAMBERScheduled maintenance interval has been reached.Perform required service per operator's manual.
Hydraulic OilAMBERHydraulic oil level low or filter restriction detected.Check hydraulic fluid level and replace filter if needed.
Air FilterAMBEREngine air filter is restricted, causing reduced power and fuel efficiency.Clean or replace air filter element.
Low FuelAMBERFuel level is low; refuel soon to avoid running out on site.Add diesel fuel; ensure proper fuel type.

Most Important Warning Lights

Overload Warning

Common causes

  • Excessive load weight
  • Improper load distribution
  • Faulty load sensor

What to do

Immediately lower and reduce load to within rated capacity. If light persists, inspect the load sensing system and recalibrate per Snorkel service manual.

Engine Overheating

Common causes

  • Low coolant level
  • Faulty radiator fan
  • Blocked radiator fins

What to do

Stop engine, let cool, then check coolant level and add 50/50 mix. Clean debris from radiator and ensure fan belt tension is correct.

Hydraulic Overheat

Common causes

  • Continuous heavy operation
  • Low hydraulic oil
  • Clogged oil cooler

What to do

Shift to less demanding work, allow system to cool, check hydraulic oil level and top up with recommended fluid. Clean the oil cooler fins.

Low Oil Pressure

Common causes

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

What to do

Stop engine immediately, check oil level with dipstick. If low, add oil; if light stays, do not restart – call for service.

Master Warning (Stop)

Common causes

  • Multiple system faults
  • Critical engine or hydraulic issue
  • ECU fault

What to do

Stop machine, note any other illuminated lights, and consult the manual. Reset after fixing underlying causes or contact Snorkel support.

Frequently Asked Questions

What does the amber Master Caution light mean on my Snorkel 400S?

It indicates a non-critical fault that needs attention soon. Check the display for which specific system is warning, such as low fuel or hydraulic temperature.

Why does my Snorkel 400S show overload even with a light load?

Possible sensor misalignment or calibration error. Ensure the load is centered and within rated capacity. If light persists, recalibrate the load moment indicator per the service manual.

How often should I service the air filter on the Snorkel 400S?

Inspect every 50 hours in dusty conditions; replace when the restriction indicator shows red or at scheduled intervals per the operator's manual.

Can I operate the Snorkel 400S with the seatbelt warning light on?

No. The machine will restrict travel and lift functions until the seat belt is fastened. Always buckle up before operating.

What should I do if the hydraulic oil temperature warning comes on?

Reduce load and idle the engine to allow oil to cool. Check hydraulic oil level and cooler cleanliness. If it persists, avoid heavy use until serviced.

How do I reset the service hour meter reminder on the Snorkel 400S?

The reminder resets after performing the service and entering the reset procedure via the instrument panel menu. See your dealer if unsure.
