The Bobcat 773 is a reliable and powerful skid steer loader that’s commonly used in construction, landscaping, and various other industries. However, like any piece of heavy machinery, it can sometimes encounter problems that require immediate attention. One of the most common issues owners and operators face is the appearance of a red warning light on the dashboard, which can signal several potential problems.
Understanding the cause of this warning light and how to address it is essential for keeping your Bobcat 773 in optimal working condition. In this article, we’ll explore common reasons for a red warning light, how to troubleshoot the issue, and what steps to take to fix it.
Why Is the Red Warning Light On?
The red warning light on the Bobcat 773 indicates a serious issue that could lead to further damage if not addressed quickly. This light is designed to alert the operator that something is wrong with the machine's vital systems. Several possible causes for the red warning light to illuminate include:
1. Hydraulic System Problems
One of the most common reasons for the red warning light to turn on is a malfunction in the hydraulic system. The Bobcat 773 uses hydraulics for functions like lifting the loader arms, moving attachments, and controlling other essential functions. If the hydraulic fluid level is low, if there is air in the system, or if there’s a hydraulic component failure, the red warning light may appear.
Common hydraulic issues include:
Engine overheating is another common cause of a red warning light. Overheating can occur due to several factors:
Electrical issues in the Bobcat 773 can also cause the red warning light to illuminate. Common electrical problems include:
Low oil pressure is another potential cause of a red warning light. The oil pressure is critical for the lubrication and functioning of the engine’s internal components. If the oil pressure is too low, it can cause significant damage to the engine. Possible causes of low oil pressure include:
1. Check Fluid Levels
Start by checking the machine’s fluid levels, including hydraulic fluid, coolant, and engine oil. Low fluid levels are often the root cause of the red warning light. Make sure each fluid reservoir is topped off according to the manufacturer's specifications.
2. Inspect the Hydraulic System
If you suspect hydraulic issues, check for leaks in the hydraulic hoses, valves, and cylinders. Low hydraulic fluid or air in the lines can reduce system efficiency. If there are no visible leaks, try bleeding the hydraulic system to remove any trapped air. Ensure the hydraulic filter is clean and in good condition.
3. Test the Engine Coolant
Overheating is another common cause of the red warning light. Check the coolant level and inspect the radiator for blockages. If the radiator is clogged with dirt or debris, clean it thoroughly. If the coolant level is low, top it off with the correct type of coolant. Also, inspect the thermostat to ensure it’s functioning properly.
4. Inspect the Battery and Electrical System
Electrical issues such as a dead battery or loose terminals can trigger the red warning light. Inspect the battery and ensure the terminals are clean and tight. Test the alternator to confirm it’s charging the battery correctly. If the alternator is faulty, replace it.
5. Check the Oil Pressure
Check the oil level and ensure the engine is adequately lubricated. If the oil level is low, top it off with the correct type of oil. If the oil pressure remains low despite a proper oil level, the oil pump or pressure sensor may be faulty, requiring further diagnosis and repair.
When to Call a Professional
If you’ve gone through these troubleshooting steps and the red warning light remains on, it may be time to call a professional technician. Some issues, like a faulty hydraulic pump or electrical system problem, may require specialized tools and expertise to fix.
A trained mechanic will have the knowledge and experience to diagnose and repair the issue quickly, preventing further damage to your Bobcat 773 and ensuring it remains operational.
Conclusion: Stay Ahead of the Issues
The red warning light on the Bobcat 773 is a serious indication that something is wrong with the machine. Whether it’s a hydraulic issue, engine overheating, electrical failure, or low oil pressure, it’s crucial to address the problem promptly. Regular maintenance, including checking fluid levels and inspecting key components, can help prevent these issues from occurring.
By following the steps outlined in this guide, you can troubleshoot common causes of the red warning light and keep your Bobcat 773 running smoothly. However, if you’re unable to resolve the issue on your own, don’t hesitate to reach out to a professional for help. Proper care and attention to your equipment will extend its lifespan and improve performance in the long run.

The Bobcat 773 uses hydraulics for functions like lifting the loader arms, moving attachments, and controlling other essential functions. If the hydraulic fluid level is low, if there is air in the system, or if there’s a hydraulic component failure, the red warning light may appear.
Common hydraulic issues include:
- Low hydraulic fluid levels: Check the fluid reservoir and top it up if necessary.
- Hydraulic pump failure: The hydraulic pump is crucial for operating various components of the machine. If it fails, the red warning light may be triggered.
- Air in the hydraulic lines: Air trapped in the hydraulic system can reduce efficiency and trigger a warning.
Engine overheating is another common cause of a red warning light. Overheating can occur due to several factors:
- Low coolant levels: If the engine’s coolant levels are low, it may cause the engine to overheat. Regularly check and top off the coolant as needed.
- Faulty thermostat: A malfunctioning thermostat can prevent the engine from cooling properly. If the thermostat is stuck in the closed position, it may cause the engine to overheat.
- Clogged radiator: A dirty or clogged radiator prevents airflow, leading to overheating. Cleaning or replacing the radiator may be necessary to fix the issue.
Electrical issues in the Bobcat 773 can also cause the red warning light to illuminate. Common electrical problems include:
- Loose or corroded battery terminals: Poor connections can prevent the machine from starting or running properly, triggering the warning light.
- Faulty alternator: The alternator is responsible for keeping the battery charged. If it’s malfunctioning, the machine may lose electrical power, leading to a warning.
- Wiring issues: Damaged or disconnected wires can cause the machine’s electrical system to fail and trigger the warning light.
Low oil pressure is another potential cause of a red warning light. The oil pressure is critical for the lubrication and functioning of the engine’s internal components. If the oil pressure is too low, it can cause significant damage to the engine. Possible causes of low oil pressure include:
- Low oil levels: Check the engine oil level and top it up if necessary.
- Faulty oil pressure sensor: A faulty sensor could falsely trigger the red warning light even if the oil pressure is normal.
- Oil pump failure: If the oil pump fails, it may not circulate oil effectively, leading to low oil pressure and potential engine damage.
