How to Lift the Arms on a Disabled Case TR310 Skid Steer

[MikePhua]

The user discussed how to lift the arms on a disabled Case TR310 skid steer loader when the engine won't start. Since the hydraulic system relies on engine power to operate, if the engine fails to start, the hydraulic system won't function, and the arms cannot be lifted. Therefore, a special method is required to manually lift the arms to ensure the equipment can be operated or serviced.
Preparation for Manual Arm Lifting

1. Ensure the Machine is in a Safe Position
   Before beginning any operation, ensure that the machine is on level ground, and the parking brake is engaged. This will prevent the machine from moving or tilting during the operation, ensuring safety throughout the process.
   
2. Disconnect the Power Supply
   To avoid interference with the electrical system, disconnect the machine's battery first. This prevents any accidental startup or electrical failure during the operation.
   
3. Gather Necessary Tools
   Refer to the operator’s manual and gather the appropriate tools (such as a manual hydraulic pump, manual tools, etc.). In some cases, an external hydraulic device may be required to lift the arms manually.
   

Steps for Manual Arm Lifting

1. Locate and Connect the Manual Pump Port
   In the machine’s operator manual, locate the manual pump connection point. For the Case TR310, there is typically a dedicated port for connecting an external manual pump. Follow the instructions in the manual to properly connect the manual pump.
   
2. Inject Hydraulic Fluid
   Using the manual pump, gradually inject hydraulic fluid into the hydraulic system. This process should be done evenly and steadily to avoid fluctuations in oil pressure that could damage the hydraulic system. Ensure that the hydraulic fluid used meets the manufacturer's specified standards for system compatibility.
   
3. Manually Operate the Arms
   After the hydraulic system is connected, use the manual pump to operate the hydraulic system, slowly lifting the arms of the machine. During this process, monitor the system to ensure stable oil pressure and that there are no leaks in the hydraulic lines. Gradually raise the arms until the desired position is reached.
   
4. Check and Confirm Hydraulic System Status
   After lifting the arms, check the hydraulic system and all connected components to ensure there are no leaks. Pay special attention to the connections, ensuring everything is securely fastened to avoid any safety risks during future use.
   

Conclusion
When the Case TR310 skid steer loader won't start, it is possible to manually lift the arms using a hydraulic pump and the hydraulic system. This process requires ensuring the machine is stable and safe while using the correct tools and procedures. Regularly inspecting the hydraulic system and external hydraulic equipment is essential to ensure proper functioning of the machine.
