Troubleshooting steps:
- Check battery connections for tightness and corrosion.
- Inspect the drive belt for wear or proper tension.
- If the light remains on, have the alternator and charging system tested.
Hydraulic Oil Temperature Warning Light
A red hydraulic oil temperature light suggests that the hydraulic system is overheating. This can lead to reduced performance and potential damage to hydraulic components.
Potential issues:
- Low hydraulic oil level
- Clogged hydraulic oil cooler
- Faulty hydraulic pump
- Restricted hydraulic lines
Troubleshooting steps:
- Check the hydraulic oil level and top up if necessary.
- Inspect the hydraulic oil cooler for debris or blockages.
- Reduce the workload on the machine to allow the system to cool.
- If the problem persists, consult a technician to check the hydraulic pump and system.
Air Filter Restriction Warning Light
This yellow light indicates that the air filter is becoming clogged and needs attention.
Potential issues:
- Dirty air filter
- Damaged air filter housing
Troubleshooting steps:
- Locate the air filter and inspect it for dirt and debris.
- Clean or replace the air filter as necessary.
- Check the air filter housing for damage or loose connections.
Fuel Level Warning Light
A yellow fuel level warning light simply indicates that the fuel level is low and the tank needs to be refilled soon.
Troubleshooting steps:
- Refuel the machine at the next convenient opportunity.
- If the light remains on after refueling, check for a faulty fuel gauge or sender unit.
DEF (Diesel Exhaust Fluid) Level Warning Light
For Case skid steers equipped with Tier 4 engines, this yellow light indicates that the DEF level is low and needs to be replenished.
Troubleshooting steps:
- Refill the DEF tank with the correct type of DEF.
- If the light persists, check for blockages in the DEF system or consult a technician.
Check Engine Warning Light
A yellow check engine light can indicate a variety of engine-related issues. It’s often accompanied by other warning lights or error codes.
Potential issues:
- Sensor malfunctions
- Emissions system problems

- Consult a qualified technician for a thorough diagnosis and repair.
Transmission Warning Light
This yellow light suggests an issue with the transmission system.
Potential issues:
- Low transmission fluid
- Overheating transmission
- Internal transmission damage
Troubleshooting steps:
- Check the transmission fluid level and condition.
- Allow the machine to cool if overheating is suspected.
- If the light persists, have a technician inspect the transmission.
Parking Brake Warning Light
A red parking brake light indicates that the parking brake is engaged. It should illuminate when the parking brake is set and extinguish when released.
Troubleshooting steps:
- Ensure the parking brake is fully released before operation.
- If the light remains on, check for a stuck parking brake mechanism or faulty switch.
Operator Safety and Equipment Maintenance
Understanding warning lights is just one aspect of safe and efficient skid steer operation. Here are some additional tips to ensure operator safety and proper equipment maintenance:
- Always perform a pre-operation inspection: Before starting your workday, conduct a thorough visual inspection of your Case skid steer. Check for fluid leaks, tire condition, and any visible damage.
- Follow the maintenance schedule: Adhere to the manufacturer’s recommended maintenance schedule. Regular oil changes, filter replacements, and system checks can prevent many issues before they trigger warning lights.
- Keep the machine clean: Regularly clean your skid steer, paying special attention to the radiator and oil cooler. Debris buildup can lead to overheating issues.
- Train operators properly: Ensure all operators are thoroughly trained on the specific Case skid steer model they’ll be using, including the meaning of all warning lights and proper response procedures.
- Use genuine parts: When replacements are necessary, use genuine Case parts to ensure proper fit and function.
- Monitor fluid levels: Regularly check and top up engine oil, hydraulic fluid, coolant, and DEF (if applicable). Low fluid levels can trigger warning lights and cause damage if left unchecked.
- Pay attention to unusual noises or vibrations: Often, mechanical issues will present themselves through unusual sounds or vibrations before triggering a warning light. Address these promptly to prevent more serious problems.
- Keep a maintenance log: Maintain a detailed record of all maintenance activities, repairs, and warning light occurrences. This can help identify patterns and predict potential issues.
- Use the right attachments: Only use attachments that are compatible with your specific Case skid steer model. Improper attachments can strain the hydraulic system and trigger warnings.
- Understand your machine’s limits: Don’t push your skid steer beyond its rated capacities. Overloading can lead to premature wear, damage, and safety hazards.
By following these guidelines and promptly addressing any warning lights that appear, you can ensure the safe and efficient operation of your Case skid steer loader. Remember, when in doubt about a warning light or persistent issue, it’s always best to consult with a qualified technician or your local Case dealer. They have the expertise and specialized tools to diagnose and resolve complex problems, helping to keep your equipment running smoothly and productively.
