Gehl Warning Lights and Symbols: Complete Guide

The Gehl skid steer instrument cluster is designed for rugged operation, providing clear alerts for engine, hydraulic, and safety systems specific to your loader. Understanding these lights helps prevent costly downtime and ensures operator safety in tight jobsites.

How to read the colors: Red lights indicate immediate stop conditions that require urgent attention, amber warns of service needs or system faults, while green/blue signals active systems or normal operation.

Gehl skid steer Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDOn Gehl skid steers, this red stop light illuminates when a critical fault is detected, such as engine shutdown or hydraulic failure.Stop the machine immediately, shut off engine, and consult manual.
Master CautionAMBERThis amber caution lamp appears on Gehl models for non-critical system warnings like low fluid or service reminders.Check the secondary display for specific fault codes and schedule service soon.
Check Engine (MIL)AMBERLit when the Gehl's engine computer detects emissions or performance issues, common in Yanmar or Kubota powered units.Reduce load, check for unusual noises, and have dealer diagnose codes.
Engine Oil PressureREDIf this red light stays on in your Gehl, engine oil pressure is dangerously low, risking bearing damage on the turbo or crank.Stop engine immediately, check oil level and for leaks; do not restart.
Battery / ChargingREDIndicates the Gehl's alternator is not charging the battery, often due to a loose belt or failed alternator on 40-series models.Check alternator belt tension and wiring; if light persists, replace alternator.
Coolant TemperatureREDOverheating can occur in Gehl skid steers when the radiator is clogged with debris or coolant level is low.Stop machine, let cool, check coolant level and clean radiator fins.
Hydraulic Oil TemperatureAMBERThis amber light warns that the hydraulic oil in your Gehl is above normal operating temperature, reducing lift performance.Reduce heavy load cycles, check oil level and cooler for blockages.
Glow Plug / PreheatAMBEROn cold-start Gehl diesels, this symbol indicates the glow plugs are heating the intake air; wait until it turns off.Turn key to 'on' position and wait for light to go out before cranking.
Low FuelAMBERWhen the Gehl's fuel level drops below 10%, this amber light reminds you to refuel to avoid air in the injection system.Refuel with clean diesel as soon as possible.
PParking BrakeREDOn Gehl skid steers, this red light stays on if the parking brake is engaged while the engine is running, preventing drive engagement.Release parking brake before moving; if light persists, check brake switch.
Fasten Seat BeltREDThis red warning appears on Gehl models when the operator is not buckled, and the machine may lock out lift/tilt functions.Fasten seat belt immediately to restore full machine operation.
High BeamBLUEBlue indicator shows the high-beam headlights are on, useful for night work but may blind other operators.Switch to low beam when other equipment is nearby.
Work LightsGREENGreen light confirms the auxiliary work lights are activated, common for Gehl machines equipped with LED lighting packages.Toggle switch as needed; no action required if using lights.
Reduced Power (Limp Mode)AMBERIf this amber light glows steady on your Gehl, the engine control has limited power to protect against overheating or sensor faults.Reduce load and drive slowly to a safe area; check diagnostic codes.
Service / Hour MeterAMBERThis amber symbol reminds Gehl operators that scheduled service is due, such as oil change or filter replacement at 500-hour intervals.Perform per Gehl maintenance schedule; reset after service.

Most Important Warning Lights

Engine Oil Pressure Failure

Common causes

  • Low oil level
  • Damaged oil pump
  • Clogged oil filter

What to do

On a Gehl skid steer, shut down immediately, add oil if low; if light stays on, inspect oil pressure sensor and replace pump if needed.

Hydraulic System Overheat

Common causes

  • Blocked hydraulic oil cooler
  • Low oil level
  • Excessive continuous load

What to do

Pause heavy operations on your Gehl, clean cooler fins with compressed air, and top off hydraulic fluid with Gehl-approved oil.

Coolant Overheating

Common causes

  • Radiator clogged with debris
  • Low coolant level
  • Faulty thermostat

What to do

Stop the Gehl, allow to cool, then clean radiator core and check for leaks; replace thermostat if temperature remains high.

Charging System Failure

Common causes

  • Loose alternator belt
  • Failed alternator
  • Battery terminal corrosion

What to do

Inspect belt tension on your Gehl, tighten or replace; test alternator output at battery; clean terminals with baking soda solution.

Frequently Asked Questions

Why does my Gehl skid steer's master warning light come on when operating on a slope?

The master warning may activate due to low oil level or a tilt sensor fault; check engine oil and ensure the machine is on level ground for accurate readings.

Can I keep running the Gehl with the hydraulic oil temperature light on?

No, continued operation may damage hydraulic components; stop and let the system cool, then clean the cooler and check fluid level.

What does the amber check engine light mean on a Gehl with a Yanmar engine?

It indicates an emissions or sensor fault; common on Tier 4 models. Check for loose connections or clogged DPF filter; if persistent, have dealer scan codes.

How do I reset the service hour light on a Gehl skid steer?

Turn the key to ON, press and hold the hour meter reset button (usually near the display) until the light flashes, then release. Refer to your model's manual.

My Gehl's battery light flickers at idle—is that normal?

Slight flicker can be normal if the alternator is charging at low RPM, but steady flickering indicates a worn belt or failing alternator; test output to be safe.

Why does the reduced power light come on when digging with heavy attachments?

The Gehl's engine controller detects high load and reduces power to prevent overheating; reduce digging depth or increase RPM to clear the condition.
