Case CE CX145D SR Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault detected in the CX145D SR, such as engine shutdown or hydraulic failure, demands immediate stopping. | Stop the excavator safely and consult the fault code on the display. | |
| Master Caution | AMBER | A non-critical fault in the CX145D SR requires attention but does not mandate immediate stop. | Check the message center and address the indicated system soon. | |
| Check Engine (MIL) | AMBER | The CX145D SR's engine control unit detected an emission or performance issue, possibly related to the DPF or fuel system. | Schedule service to diagnose with the Case service tool. | |
| Engine Oil Pressure | RED | Low oil pressure in the CX145D SR's engine can cause severe damage if not addressed immediately. | Stop the excavator and check oil level and filter. | |
| Battery / Charging | RED | The alternator or battery in the CX145D SR is not charging properly, risking electrical system failure. | Turn off non-essential loads and have the charging system tested. | |
| Coolant Temperature | RED | Engine coolant temperature in the CX145D SR is too high, possibly due to low coolant or a clogged radiator. | Stop the excavator and let it cool; inspect coolant level and fan belt. | |
| Hydraulic System | RED | A major hydraulic fault in the CX145D SR, such as low oil level or pump failure, requires immediate attention. | Stop the excavator and check hydraulic oil level and for leaks. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature in the CX145D SR is high or the filter is bypassing, reducing efficiency. | Reduce load and allow system to cool; check oil condition and filter. | |
| Engine Oil Temperature | AMBER | Engine oil temperature in the CX145D SR is elevated, which may degrade lubrication. | Reduce engine load and allow to cool; check oil level and cooler. | |
| Air Filter | AMBER | The CX145D SR's air intake filter is restricted, causing reduced engine power and fuel economy. | Clean or replace the air filter element. | |
| Fuel Filter / Water Separator | AMBER | Water in the fuel system or a clogged filter on the CX145D SR can cause injector damage. | Drain the water separator and replace the fuel filter. | |
| Service / Hour Meter | AMBER | The CX145D SR is due for scheduled maintenance based on engine hours. | Perform the required service per the operator's manual. | |
| Work Lights | GREEN | Indicates the work lights on the CX145D SR are turned on, improving visibility at night. | No action needed unless lights are unwanted. | |
| Beacon / Rotating Light | GREEN | The overhead beacon on the CX145D SR is active, signaling the machine is in operation. | Ensure beacon is used as required for safety. | |
| Swing / Slew Lock | AMBER | The swing lock on the CX145D SR is engaged, preventing slewing of the upper structure. | Release the swing lock before moving the excavator. | |
| Overload / Capacity | RED | The CX145D SR has exceeded its lifting capacity, risking stability or structural damage. | Immediately reduce load to safe levels. | |
| Seat Belt | RED | The operator seat belt in the CX145D SR is not fastened, posing a safety risk. | Fasten your seat belt before operating. | |
| High Beam | BLUE | The high beam headlights on the CX145D SR are illuminated for long-distance visibility. | Dim when approaching other vehicles. | |
| Glow Plug / Preheat | AMBER | The CX145D SR's engine preheat system is active when cold starting. | Wait for the indicator to turn off before cranking. | |
| Reduced Power (Limp Mode) | AMBER | The CX145D SR's engine has reduced power to prevent damage due to a fault. | Operate at reduced speed and have the system diagnosed. | |
| Fasten Seat Belt | AMBER | A reminder that the seat belt in the CX145D SR is not engaged. | Fasten seat belt immediately for safety. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Clogged radiator fins
- Faulty thermostat
What to do
Stop the CX145D SR and let the engine cool. Check coolant reservoir; if low, add approved coolant. Clean radiator fins with compressed air.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic pump cavitation
- Contaminated oil
What to do
Stop the excavator and check hydraulic oil level. Look for external leaks. If oil is milky or contains debris, replace filters and oil.
Electrical Charging Issue
Common causes
- Alternator belt slippage
- Battery corrosion
- Faulty alternator
What to do
Check alternator belt tension on the CX145D SR. Clean battery terminals and test charging voltage; replace alternator if needed.
Engine Oil Pressure Loss
Common causes
- Low oil level
- Restricted oil filter
- Worn engine bearings
What to do
Immediately stop the CX145D SR. Check dipstick and add oil if low. Replace oil filter; if pressure remains low, consult a technician.
Frequently Asked Questions
What does the red 'Master Warning' light mean on my CX145D SR?
It indicates a critical system fault—stop the excavator immediately and check the display for a fault code. Common issues include engine shutdown or hydraulic failure.
Why is the amber 'Reduced Power' light on during heavy digging?
The CX145D SR enters limp mode to protect the engine or hydraulic system from damage. Reduce digging force and have the system inspected by a Case dealer.
How often should I service the fuel filter on the CX145D SR?
Every 250 hours or as indicated by the service light. Drain the water separator regularly to prevent injector damage.
Can I operate the excavator with the amber 'Hydraulic Oil' light on?
You can continue under reduced load, but high oil temperature degrades components. Allow the system to cool and check oil level and heat exchanger cleanliness.
What does the green 'Beacon' light mean?
It confirms the rotating beacon is on, alerting nearby workers that the CX145D SR is in operation. Always use it in high-traffic areas.
How do I reset the service hour meter on the CX145D SR?
The reset is performed by a dealer after completing scheduled maintenance. Attempting to reset it yourself may not clear the light.
