The Gehl R220 skid steer loader's instrument cluster displays critical alerts for engine, hydraulic, and electrical systems. Recognizing these indicators promptly can prevent costly damage and downtime.
Gehl R220 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | Indicates a critical fault—such as engine overheat or hydraulic failure—that requires immediate engine stop on the Gehl R220. | Stop the engine immediately and consult the operator's manual for troubleshooting. | |
| Master Caution | AMBER | Lights when a non-critical issue (e.g., low fluid or minor sensor error) needs attention in your Gehl R220. | Check the other warning lights to identify the issue and service as needed. | |
| Check Engine (MIL) | AMBER | Signals an engine management problem like a sensor fault or emission control issue specific to the Gehl R220's diesel engine. | Have the engine diagnostics scanned by a dealer to pinpoint the fault. | |
| Engine Oil Pressure | RED | Indicates low oil pressure, which can cause severe engine damage if ignored on the Gehl R220. | Shut off the engine and check oil level; add oil if needed and look for leaks. | |
| Battery / Charging | RED | Shows that the battery is not charging or voltage is low, often due to alternator failure on the Gehl R220. | Check battery connections and alternator belt; if light stays on, replace alternator. | |
| Coolant Temperature | RED | Lights when the engine coolant exceeds normal operating range, risking overheating in the Gehl R220. | Stop the engine, let it cool, then inspect coolant level and radiator for debris. | |
| Hydraulic System | AMBER | Warns of high oil temperature or a pressure drop in the hydraulic system of the Gehl R220. | Check hydraulic oil level and condition; reduce load until light goes out. | |
| Hydraulic Oil | AMBER | Indicates low hydraulic oil level or a filter restriction in the Gehl R220's hydrostatic drive. | Top off hydraulic fluid with recommended oil and inspect for leaks. | |
| Air Filter | AMBER | Alerts when the engine air filter is clogged, reducing performance and fuel economy on the Gehl R220. | Clean or replace the air filter and reset the service indicator. | |
| Fuel Filter / Water Separator | AMBER | Lights when the fuel filter needs replacement or water has accumulated in the separator on the Gehl R220. | Drain water from the separator and replace the fuel filter if necessary. | |
| Glow Plug / Preheat | GREEN | Illuminates during engine preheat in cold starts; on the Gehl R220, wait for it to turn off before cranking. | Allow the light to turn off (usually a few seconds) then start the engine. | |
| Seat Belt | RED | Indicates the operator's seat belt is not fastened, a safety requirement on the Gehl R220. | Fasten your seat belt securely before operating. | |
| Parking Brake | RED | Shows that the parking brake is engaged or not fully released on the Gehl R220. | Release the parking brake fully before moving the machine. | |
| High Beam | BLUE | Indicates the high-beam headlights are on, increasing visibility in dark conditions on the Gehl R220. | No action required; switch to low beam when near other operators. | |
| Work Lights | GREEN | Lights when the auxiliary work lights are activated for nighttime operation on the Gehl R220. | Turn off work lights when not needed to save battery. | |
| Beacon / Rotating Light | GREEN | Indicates the rotating beacon is on, improving visibility of the Gehl R220 on job sites. | Ensure beacon is operational for safety; no further action needed. | |
| Service / Hour Meter | AMBER | Reminds that scheduled maintenance is due based on engine hours on the Gehl R220. | Perform the required service as per the maintenance schedule. | |
| Low Fuel | AMBER | Warns that the fuel level is low and refueling is needed soon for the Gehl R220. | Refill the fuel tank with diesel to avoid running out during operation. | |
| Water in Fuel | AMBER | Indicates water has been detected in the fuel system, which can cause injector damage on the Gehl R220. | Drain the water separator immediately and check for fuel contamination. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Cooling fan failure
What to do
Stop the engine and let it cool. Check coolant level and add if low. Inspect radiator for debris and clean as needed. If recurring, have the cooling system serviced.
Hydraulic System Failure
Common causes
- Low hydraulic oil
- Clogged filter
- Pump cavitation
What to do
Check hydraulic oil level and add recommended fluid. Replace the hydraulic filter if clogged. Reduce load to avoid pump damage and inspect for leaks.
Electrical Charging Problem
Common causes
- Failed alternator
- Loose battery cables
- Bad battery
What to do
Inspect battery connections and clean corrosion. Test battery voltage; if below 12.4V, recharge or replace. If alternator not charging, replace it.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn bearings
What to do
Shut down engine immediately. Check oil level and add if low. If light persists, do not run engine; have it inspected for internal damage.
Frequently Asked Questions
What should I do if the Master Warning (red) light comes on while operating?
Stop the engine immediately and assess the other warning indicators. Common causes include engine overheating or hydraulic failure. Do not restart until the issue is resolved.
Why is the amber hydraulic light on but the machine runs fine?
It may indicate high oil temperature from heavy use or a low fluid level. Check the hydraulic oil level and allow the system to cool if it's hot. Reduce load if needed.
How often should I replace the air filter on my Gehl R220?
Replace the air filter when the amber air filter indicator comes on, or every 250 operating hours in normal conditions. Clean or replace sooner in dusty environments.
Can I operate the machine with the seat belt light on?
No, the seat belt must be fastened for safe operation. The light is a safety reminder; the machine may not function properly without the belt fastened.
What does the green glow plug light mean in cold weather?
It indicates the engine preheat cycle is active. Wait for the light to turn off before starting the engine to ensure reliable ignition in cold temperatures.
How do I reset the hour meter after servicing?
The hour meter reset procedure varies. Typically, turn the ignition on and press a button on the cluster or follow the service reset sequence in the manual. Refer to your Gehl R220 operator's manual for exact steps.
