Float Function in the 2002 CAT 252 Skid Steer Loader

[MikePhua]

1. Issue Overview
On the Panswork forum, a user discussed the float function in the 2002 CAT 252 skid steer loader. The float function is an important feature in skid steers, allowing the bucket to float freely over the surface without hydraulic pressure. This feature is particularly useful for certain tasks, such as grading soil or clearing surfaces, by ensuring smoother operation and reducing damage to the ground.
2. How the Float Function Works
The float function works by releasing hydraulic pressure, allowing the bucket or other attachments to follow the contour of the ground naturally, without being controlled by the hydraulic system. This prevents unnecessary pressure on the surface and ensures smoother operation.

1. Hydraulic Release: When the float function is engaged, the hydraulic system releases some of its pressure, allowing the bucket to naturally follow the ground's surface. This eliminates any interference from the hydraulic system, providing more precise control during operation.
   
2. Ideal Applications: The float function is especially beneficial for tasks that require grading or surface clearing, such as land leveling, snow removal, or clearing dirt piles. It helps avoid excessive pressure on the ground, improving both efficiency and the quality of the work.
   
3. Auto Float: Some machines may feature an automatic float function, meaning the machine automatically releases hydraulic pressure without requiring the operator to take additional steps. This is especially useful when switching between tasks frequently, as it streamlines operation.
   

3. Common Issues and Troubleshooting
While the float function is highly useful, there may be times when it fails to engage or operate properly. Here are some potential causes and troubleshooting tips:

1. Hydraulic System Issues: The float function depends on the hydraulic system's ability to function properly. If the hydraulic fluid is low, or there is a failure in the hydraulic system, the float function may not work. Check the hydraulic fluid level and condition, as well as the hydraulic pump and valves, to ensure they are functioning properly.
   
2. Control Valve Problems: In some cases, the valve responsible for controlling the float function may malfunction, preventing proper operation. Inspect the control valve for dirt, damage, or malfunction, and ensure it operates as intended.
   
3. Float Mode Setting Error: Some skid steers allow the operator to adjust the float function through a control panel or settings. If the setting is incorrect or the function has been accidentally turned off, it can prevent the float function from engaging. Ensure all settings are correct and refer to the operator’s manual to verify the settings.
   

4. Conclusion and Recommendations
The float function is an essential feature in skid steer loaders, enabling the bucket or attachment to float freely by releasing hydraulic pressure, resulting in more precise and efficient operation. Operators should ensure that the hydraulic system and control valves are in good working condition to properly engage the float function.
If the float function fails to engage, troubleshooting should begin by checking the hydraulic system, control valve, and settings. Regular maintenance of the hydraulic system and following the operator’s manual can significantly improve the performance of the float function.
