Introduction: The Bobcat S175 and its Performance
The Bobcat S175 is a popular skid-steer loader, known for its reliability and versatility on various job sites. Whether you're using it for digging, lifting, or material handling, the S175 delivers strong performance. However, like any heavy machinery, it can experience technical issues that may impact its functionality. One such issue is the appearance of error codes, with the 32-39 error code being a common one reported by operators.
This article will explore what the Bobcat S175 32-39 error code means, how to troubleshoot the issue, and how to resolve it effectively. We'll also include tips from operators and technicians on maintaining your Bobcat loader and preventing future errors.
What Does the Bobcat S175 32-39 Error Code Mean?
The 32-39 error code on the Bobcat S175 refers to a hydraulic system issue. Specifically, it indicates a problem with the hydraulic pressure sensor, often linked to the hydraulic fluid flow or pressure in the system. This error could be triggered by several potential causes, including low hydraulic fluid, a malfunctioning sensor, or blockages in the hydraulic lines.
Key Causes of the 32-39 Error Code

1. Low Hydraulic Fluid Level
   One of the most common reasons for the 32-39 error code is insufficient hydraulic fluid in the system. Low fluid levels can lead to decreased pressure, causing the system to malfunction.
   
2. Faulty Pressure Sensor
   The hydraulic pressure sensor is a critical component in the Bobcat S175’s hydraulic system. If the sensor is damaged or malfunctioning, it may send incorrect readings to the control module, triggering the error code.
   
3. Hydraulic Line Blockage
   A clogged hydraulic line can prevent the fluid from flowing properly, which can result in low pressure and the 32-39 error code.
   
4. Hydraulic Pump Failure
   In some cases, a failure of the hydraulic pump itself can cause pressure issues. If the pump isn’t functioning properly, it won't be able to maintain the necessary fluid flow to operate the machine’s hydraulic systems effectively.
   

How to Troubleshoot the Bobcat S175 32-39 Error Code
When you encounter the 32-39 error code, it’s essential to systematically check the hydraulic system. Here’s a step-by-step guide to troubleshooting the issue:

1. Check Hydraulic Fluid Level
   First, ensure that the hydraulic fluid level is adequate. Low fluid can be the root cause of many hydraulic issues. If the fluid level is low, top it up with the appropriate fluid as specified in the operator’s manual.
   
2. Inspect the Hydraulic Pressure Sensor
   The next step is to inspect the hydraulic pressure sensor. Look for any signs of damage or wear. If the sensor appears faulty, it may need to be replaced. Make sure to clean any debris from around the sensor to ensure accurate readings.
   
3. Check for Blockages in the Hydraulic Lines
   Inspect the hydraulic lines for blockages or leaks. Blockages can severely impact hydraulic pressure and cause the 32-39 error code. Clear any obstructions and repair any damaged hoses or lines.
   
4. Test the Hydraulic Pump
   If the sensor and fluid levels are fine, the next step is to test the hydraulic pump. A malfunctioning pump will not generate the correct fluid pressure, which could be triggering the error code. If the pump isn’t working properly, it may need to be replaced.
   
5. Reset the Error Code
   Once you’ve resolved the issue, reset the error code. You can do this by turning the ignition off and on again or using a diagnostic tool to clear the error code from the system. If the code persists, further investigation is required.
   

Preventing Future Hydraulic System Issues
To avoid encountering the 32-39 error code in the future, regular maintenance is essential. Here are some maintenance tips to keep your Bobcat S175 running smoothly:

• Regular Fluid Checks: Make it a habit to check the hydraulic fluid levels regularly and top them off as needed. Low fluid levels can cause a wide range of hydraulic issues, including errors like the 32-39.
  
• Replace Filters and Fluids on Schedule: Follow the manufacturer’s recommended maintenance schedule for changing hydraulic filters and fluids. Fresh, clean fluids help maintain proper pressure and prevent clogs or breakdowns in the system.
  
• Inspect Hydraulic Components: Periodically inspect the hydraulic hoses, fittings, and pressure sensors for wear and tear. Early detection of faulty parts can prevent more costly repairs later on.
  
• Use the Right Hydraulic Fluid: Always use the recommended hydraulic fluid type for your Bobcat S175. The wrong type of fluid can negatively impact system performance and lead to errors like the 32-39.
  

User Experiences: Insights from Bobcat Operators
Many Bobcat S175 operators have shared their experiences with the 32-39 error code, providing valuable insights into how they addressed the issue:

• Fluid Maintenance: Operators consistently emphasize the importance of maintaining proper fluid levels and using the right type of hydraulic fluid. Regular checks are key to preventing the issue from arising in the first place.
  
• Sensor Failures: Several users have noted that the hydraulic pressure sensor is a common culprit for the 32-39 error code. Many found that replacing a faulty sensor resolved the issue, saving them from having to replace expensive components like the hydraulic pump.
  
• DIY Troubleshooting: Many operators report success in fixing the 32-39 error code themselves, with basic tools and a little mechanical knowledge. This has saved them money on service calls, especially when the problem was related to low fluid or a clogged hydraulic line.
  

Conclusion: Keeping Your Bobcat S175 in Top Condition
The 32-39 error code on the Bobcat S175 can be a frustrating issue, but with the right troubleshooting steps, it is typically easy to resolve. By checking the hydraulic fluid, inspecting the pressure sensor, and ensuring that the hydraulic system is free from blockages, most owners can quickly get their machine back up and running.
Regular maintenance is the key to preventing future errors and ensuring the long life of your Bobcat S175. With proper care and attention, your skid-steer loader will continue to perform at its best, handling tough tasks and keeping you productive on the job site.
By understanding common error codes and staying on top of maintenance, Bobcat operators can avoid downtime and ensure smooth operations for years to come.
