The Case SR220 compact track loader features a robust warning system tailored for demanding worksites. This guide explains common dashboard indicators to help you respond quickly and safely.
Case SR220 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system failure detected in your SR220, typically accompanied by a buzzer and other warning lights. | Stop the machine immediately, engage parking brake, and consult the instrument cluster for the specific fault. | |
| Master Caution | AMBER | A non-critical alert that requires attention but does not require immediate shutdown on the SR220. | Check the information display for the underlying warning and schedule service soon. | |
| Check Engine (MIL) | AMBER | The engine control module has detected a fault in the emissions or engine management system specific to your SR220's diesel engine. | Reduce load and have the fault code read by a Case dealer; avoid prolonged operation. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe operating range, risking serious internal damage to the SR220's engine. | Shut off the engine immediately and check the oil level; do not restart until the issue is resolved. | |
| Battery / Charging | RED | The alternator is not charging the battery or the charging voltage is out of range on your SR220. | Check alternator belt tension and battery connections; replace the alternator if the light persists. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded the safe limit, which can cause rapid engine damage on the SR220. | Stop the engine, let it cool, and inspect coolant level and radiator for blockages. | |
| Transmission Temperature | AMBER | The hydrostatic transmission oil is running hot, often due to heavy load or low fluid in your SR220. | Reduce load or shift to a lower gear; check transmission oil level and cooler cleanliness. | |
| Parking Brake | AMBER | Indicates the parking brake is engaged or not fully released on the SR220. | Release the parking brake before moving; if the light stays on, inspect the brake switch. | |
| Seat Belt | AMBER | The operator's seat belt is not fastened, which disables certain machine functions on the SR220. | Fasten the seat belt to allow normal operation and ensure safety. | |
| Glow Plug / Preheat | AMBER | The glow plugs are active for cold-start assistance; if the light stays on after start, a fault exists in the SR220's preheat system. | Wait for the light to go out before cranking; if it remains on, have the glow plug circuit inspected. | |
| DPF / Regeneration | AMBER | The diesel particulate filter is regenerating or requires regeneration to clear soot buildup in your SR220's exhaust. | If flashing, operate under load to assist regeneration; if solid, park and initiate parked regen per manual. | |
| Water in Fuel | AMBER | Water has been detected in the fuel/water separator, which can cause injector damage on the SR220's diesel engine. | Drain the water separator immediately; if light remains, replace the fuel filter. | |
| Low Fuel | AMBER | The fuel level in the SR220's tank is low; refuel soon to avoid running out during operation. | Refill with clean diesel fuel as soon as possible. | |
| High Beam | BLUE | The high-beam headlights are activated on your SR220 for improved visibility in dark conditions. | Dim the lights when approaching other vehicles or operators. | |
| Hydraulic System | RED | A critical hydraulic fault such as low pressure or high temperature is detected in the SR220's work circuits. | Stop the machine and check hydraulic oil level and filter; contact service if the light remains. | |
| Fasten Seat Belt | AMBER | Same as seat belt warning; operator must buckle up to enable boom and drive functions on the SR220. | Fasten the seat belt immediately. | |
| Hydraulic Oil | AMBER | The hydraulic oil temperature is elevated or oil level is low, affecting performance on your SR220. | Allow the system to cool and check hydraulic oil level; inspect for leaks. | |
| Air Filter | AMBER | The engine air filter is restricted, reducing airflow and power on the SR220. | Clean or replace the air filter element as soon as possible. | |
| Service / Hour Meter | AMBER | Indicates that scheduled maintenance is due based on engine hours on your SR220. | Perform the required service as specified in the operator's manual. | |
| Work Lights | GREEN | The work lights are turned on, providing illumination for nighttime or low-light operations on the SR220. | Turn off when not needed to save battery. | |
| Beacon / Rotating Light | GREEN | The rotating beacon is active, alerting others to the machine's presence on the job site. | Use only when required by site safety rules. | |
| Swing / Slew Lock | AMBER | The upper structure swing lock is engaged, preventing rotation of the cab or boom on the SR220. | Release the swing lock before operating the machine. | |
| Mast / Lift Limit | AMBER | The boom or lift arm is approaching its maximum height or load limit on your SR220. | Reduce lift speed or load to avoid mechanical overstress. | |
| Overload / Capacity | RED | The machine is exceeding its rated lift capacity, risking instability and tipping on the SR220. | Immediately lower the load and reduce weight; retry within capacity limits. |

Most Important Warning Lights
Engine Coolant Overheating
Common causes
- Low coolant level
- Radiator fan failure
- Clogged radiator fins
What to do
Stop the SR220 immediately, let the engine cool, then check coolant level and radiator for debris; clean or repair as needed before restarting.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump malfunction
- Excessive engine wear
What to do
Shut down the engine instantly; inspect oil level and add oil if low. If light persists, have the oil pump and engine inspected by a Case dealer.
Hydraulic System Overheating
Common causes
- Prolonged heavy load operation
- Low hydraulic oil level
- Clogged hydraulic oil cooler
What to do
Reduce load and allow the SR220 to idle; check hydraulic oil level and clean the cooler fins. If the light stays on, service the hydraulic system.
Charging System Failure
Common causes
- Broken alternator belt
- Loose or corroded battery cables
- Faulty alternator
What to do
Check the alternator belt tension and battery connections on your SR220. If the warning persists, replace the alternator.
Fuel Filter / Water Separator Clogged
Common causes
- Water contamination in fuel
- Dirty fuel filter
- Buildup of sediment in fuel tank
What to do
Drain the water separator immediately and replace the fuel filter. Use clean diesel fuel to prevent recontamination.
Frequently Asked Questions
Why does the glow plug light stay on after starting my SR220?
The glow plug light should turn off shortly after engine start. If it remains on, there may be a fault in the preheat system, such as a bad glow plug or relay; have it checked.
What should I do if the hydraulic warning light comes on while operating?
Reduce load and check the hydraulic oil level and temperature. If the light persists, shut down and inspect for leaks or a clogged filter. Oversight could lead to pump damage.
How do I interpret the master caution light on the SR220?
The master caution light alerts you to a non-critical issue. Look at the display for a specific warning symbol; address the root cause promptly to avoid escalation.
Is it safe to run the SR220 with the water in fuel light on?
No, water in the fuel can damage injectors and the fuel pump. Drain the water separator immediately and replace the fuel filter before resuming work.
Why does the check engine light flash intermittently?
A flashing check engine light indicates a severe misfire or emission fault. Reduce load immediately and have the SR220 serviced to prevent catalytic converter damage.
How do I know if my SR220 needs a DPF regeneration?
The DPF regeneration light will illuminate amber. You may notice reduced engine power. Follow the manual to perform either active or parked regeneration to clear the filter.
