SkyTrak Warning Lights and Symbols: Complete Guide

The SkyTrak aerial lift instrument cluster is designed for durability and clarity, providing operators with real-time feedback on the machine's aggressive powertrain and hydraulic systems. Understanding these indicators is crucial for safe telehandler operation and preventing costly downtime.

How to read the colors: Red indicators demand immediate action and machine shutdown; amber warns of potential issues requiring attention; green/blue indicate active systems or safe operation.

SkyTrak aerial lift Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDA critical fault has been detected in the SkyTrak's engine or hydraulic system, requiring immediate stoppage.Stop the telehandler safely, shut off engine, and consult the manual or call service.
Master CautionAMBERA non-critical system has triggered a cautionary alert, such as a sensor reading outside normal range.Reduce load, check gauges, and schedule maintenance soon.
Check EngineAMBERThe SkyTrak's diesel engine control module has logged a fault code related to emissions, fuel, or ignition.Have the fault code read by a SkyTrak dealer and address as needed.
Engine Oil PressureREDEngine oil pressure is critically low, risking severe damage to the SkyTrak's turbocharged engine.Shut down immediately, check oil level, and inspect for leaks.
Battery ChargingREDThe alternator is not charging the battery, possibly due to a failed belt or electrical fault.Stop the engine and have the charging system inspected before restarting.
Coolant TemperatureREDEngine coolant temperature has exceeded safe limits, often from heavy use or low coolant.Park the telehandler, let engine idle to cool, and check coolant level when safe.
ATTransmission TempAMBERThe SkyTrak's hydrostatic transmission fluid is running hot, reducing efficiency.Reduce load and travel speed; allow transmission to cool.
PParking BrakeREDThe parking brake is engaged or a fault in the brake system is detected.Release parking brake before moving; if light stays on, check brake system.
Seat BeltREDOperator seat belt is not fastened, which is required for telehandler operation with the load chart.Fasten seat belt immediately to continue operation.
Hydraulic OilAMBERHydraulic oil level is low or the filter is clogged, affecting boom and fork functions.Check hydraulic oil reservoir and replace filter if needed.
Low FuelAMBERThe diesel fuel level is low; the SkyTrak may have limited range for the shift.Refuel with clean diesel to avoid air in fuel lines.
Overload / CapacityREDThe SkyTrak is overloaded beyond its rated capacity, risking tip-over or structural damage.Immediately lower the load and reposition to reduce moment.
Water in FuelAMBERWater has accumulated in the fuel/water separator, which can cause injection issues.Drain the separator and replace the fuel filter as per SkyTrak maintenance schedule.
Glow Plug / PreheatAMBERThe glow plugs are active for cold starting; wait for the light to go out before cranking.Wait until light turns off, then start the engine.
Hydraulic SystemREDA serious hydraulic fault, such as pump failure or line burst, has been detected.Stop all hydraulic functions, lower boom manually if possible, and call service.

Most Important Warning Lights

Overload

Common causes

  • Exceeding rated load capacity on SkyTrak load chart
  • Improper load placement causing high moment
  • Operating on slopes exceeding limits

What to do

Immediately lower the load, reposition the SkyTrak on level ground, and redistribute the weight per the load chart.

Engine Overheat

Common causes

  • Coolant level low due to leaks or maintenance neglect
  • Radiator or cooler fins clogged with debris
  • Thermostat stuck closed or fan failure

What to do

Stop the telehandler, let the engine idle to cool, check coolant level, and clean the radiator or replace faulty components.

Low Hydraulic Pressure

Common causes

  • Hydraulic oil level too low
  • Pump worn or cavitating
  • Pressure relief valve setting incorrect or stuck

What to do

Check hydraulic oil level and condition, inspect pump for noise or vibration, and have pressure settings verified by a SkyTrak technician.

Transmission Overheat

Common causes

  • Continuous high-speed operation with heavy loads
  • Low transmission fluid level
  • Cooler or filter blockage

What to do

Shift to a lower gear range, reduce load, allow fluid to cool, and check transmission fluid and cooler for obstructions.

Electrical System Failure

Common causes

  • Alternator belt broken or slipping
  • Battery terminal corrosion or loose connections
  • Parasitic draw from aftermarket accessories

What to do

Inspect and tighten battery connections, replace alternator belt if worn, and test for draw; if unresolved, consult SkyTrak electrical diagram.

Frequently Asked Questions

What does the Master Warning light mean on my SkyTrak 6036?

It signals a critical fault requiring immediate shutdown—common causes include low engine oil pressure, overheating, or hydraulic system failure. Do not continue operating.

Can I reset the Check Engine light myself?

Only after fixing the underlying issue; the light may turn off after a few startups if the fault is resolved, but a dealer diagnostic is recommended to clear the code properly.

Why is the Hydraulic Oil light on even though the level looks full?

The filter may be clogged, or the sender could be faulty. Verify with a dipstick, and if OK, replace the hydraulic filter and check for restrictions.

How long can I run with the Transmission Temp light on?

Minimize time; reduce load and travel immediately. Prolonged operation can damage the hydrostatic transmission. Allow it to cool and investigate low fluid or blocked cooler.

Is it safe to operate with the Water in Fuel light on?

Not for long; water can damage fuel injectors. Drain the separator and replace the fuel filter as soon as possible, especially in cold weather to prevent freezing.

What should I do if the Overload light comes on while lifting?

Lower the load immediately and reposition the SkyTrak to reduce the moment arm. Recheck the load against the capacity chart for your specific model and attachments.
