Snorkel Warning Lights and Symbols: Complete Guide

The Snorkel aerial lift dashboard uses a straightforward warning light system to alert operators to machine conditions requiring attention. Indicators are color-coded for severity, with red signifying immediate stop, amber indicating caution, and green/blue confirming normal operation.

How to read the colors: Red lights demand immediate shutdown, amber lights advise prompt service, and green/blue lights show active functions like work lights or high beam.

Snorkel aerial lift Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Check EngineAMBERThe engine control system has detected a fault such as a sensor error or emission issue on this Snorkel lift.Stop the machine, check for loose connections, and contact service if the light stays on.
Engine Oil PressureREDEngine oil pressure has dropped below safe operating level, risking engine damage on your Snorkel aerial lift.Shut off engine immediately and check oil level before restarting.
Battery / ChargingREDThe charging system is not maintaining battery voltage, possibly due to a failed alternator or belt on this Snorkel lift.Stop the engine and inspect the alternator belt and connections.
Coolant TemperatureREDEngine coolant temperature has exceeded normal range, indicating overheating in your Snorkel aerial lift.Stop the engine, allow it to cool, and check coolant level and radiator for debris.
Hydraulic SystemAMBERThe hydraulic system has a fault such as low fluid or a filter restriction on this Snorkel lift.Check hydraulic oil level and inspect for leaks; if persistent, contact service.
Glow Plug / PreheatAMBERThe glow plugs are active for cold starting; when the light goes out, the engine is ready to start on this Snorkel diesel lift.Wait for the light to turn off before cranking the engine.
Water in FuelAMBERWater has been detected in the fuel system, which can cause injector damage on your Snorkel lift.Drain the fuel/water separator immediately.
Low FuelAMBERFuel level is low, requiring refueling soon to avoid engine starvation on this Snorkel aerial lift.Refill the fuel tank with clean diesel.
High BeamBLUEThe high beam headlights are switched on for improved visibility on your Snorkel lift.No action needed; dim when approaching other operators.
Work LightsGREENThe auxiliary work lights are illuminated for better visibility in low-light conditions on this Snorkel lift.No action needed; turn off when not required to save battery.
Beacon / Rotating LightGREENThe warning beacon is active, indicating the lift is in operation on your Snorkel aerial lift.No action; ensure beacon is working for safety.
Overload / CapacityREDThe platform load exceeds rated capacity, triggering a safety shutdown on this Snorkel lift.Remove excess weight immediately; the machine may have disabled lift functions.
Seat BeltREDThe operator's seat belt is not fastened, which is required for machine operation on Snorkel lifts.Fasten your seat belt before moving the lift.
PParking BrakeREDThe parking brake is engaged or a fault exists in the brake system on this Snorkel aerial lift.Release the parking brake before driving; if light stays on, check brake system.
MINLow Oil LevelAMBEREngine oil level is low and needs topping up to prevent damage on your Snorkel lift.Check and add oil to the correct level.
Brake Fluid LevelREDBrake fluid is low, indicating a possible leak or worn pads on this Snorkel aerial lift.Check brake fluid level and inspect for leaks; refill if needed.
Service / Hour MeterAMBERScheduled maintenance is due based on engine hours on this Snorkel lift.Perform the required service as per the operator's manual.

Most Important Warning Lights

Overload Condition

Common causes

  • Exceeding platform rated load
  • Uneven load distribution
  • Faulty load sensor

What to do

Remove excess weight and redistribute load evenly. If the overload light remains, inspect the load sensor and wiring on your Snorkel lift.

Low Hydraulic Oil

Common causes

  • Hydraulic fluid leak
  • Insufficient oil level
  • Failed pump or cylinder

What to do

Check hydraulic oil reservoir and top up with recommended fluid. Inspect hoses and connections for leaks; repair as needed.

Engine Overheating

Common causes

  • Low coolant level
  • Clogged radiator
  • Failed cooling fan or thermostat

What to do

Stop the engine, let it cool, then add coolant. Clean radiator fins and check fan operation. If persistent, consult a Snorkel technician.

Check Engine Light On

Common causes

  • Faulty sensor
  • Emission system issue
  • Fuel quality problem

What to do

Check engine codes using the diagnostic tool. Common fixes include replacing the DEF sensor or cleaning the DPF. Contact service if code persists.

Battery Charging Failure

Common causes

  • Loose or corroded battery terminals
  • Failed alternator
  • Broken drive belt

What to do

Clean and tighten battery connections. Inspect alternator belt tension and replace if worn. Test alternator output; replace if faulty.

Frequently Asked Questions

What should I do if the overload light stays on with no load?

First ensure the platform is empty and level. If the light remains, the load sensor may be faulty or misaligned. Reset the system by cycling the key, and if it persists, contact Snorkel service for sensor calibration.

Can I temporarily bypass the seat belt interlock?

No. The seat belt interlock is a safety feature that prevents machine operation without the belt fastened. Do not attempt to bypass it; always wear your seat belt as required by Snorkel safety guidelines.

How do I reset the service hour meter after maintenance?

The service reminder is typically reset using the diagnostic menu on the display. Refer to your Snorkel operator’s manual for the specific button sequence, or use the service tool to clear the interval.

Why is the hydraulic oil light on even though the tank is full?

A full tank but illuminated light may indicate a blocked filter, faulty pressure switch, or air in the system. Check the hydraulic filter and replace if clogged. Bleed any trapped air from the system.

What does the glow plug light mean if it flashes?

A flashing glow plug light on Snorkel lifts usually indicates a fault in the preheat system, such as a failed glow plug or relay. The engine may be hard to start; have the system diagnosed by a technician.

Is it safe to operate with the amber 'check engine' light on?

You may continue operation with caution, but the light indicates an underlying issue that could worsen. Have the fault code read and addressed promptly to avoid unexpected shutdown or damage.
