Hi Kathy, installation may differ by manufacturer but in general installing swing-back arms on a wheelchair typically involves the following steps:

1. Gather the necessary tools: You'll need a wrench or Allen key (depending on the type of fasteners used), a screwdriver, and potentially a pair of pliers.

2. Remove the existing armrests (if applicable): If your wheelchair already has armrests installed, you'll need to remove them before installing the swing-back arms. The process for removal may vary depending on the specific design of your wheelchair. Check for any bolts or screws attaching the armrests to the frame, and use the appropriate tool to remove them.

3. Prepare the swing-back arms: If your swing-back arms are not pre-assembled, follow the manufacturer's instructions to assemble them. This may involve attaching the arm pads to the armrest brackets using screws or other fasteners.

4. Position the swing-back arms: Place the swing-back arms on the wheelchair frame, aligning the mounting holes of the armrest brackets with the corresponding holes on the wheelchair frame.

5. Secure the swing-back arms: Insert the provided screws or bolts through the mounting holes of the armrest brackets and into the corresponding holes on the wheelchair frame. Use the wrench or Allen key to tighten them securely. Ensure that the swing-back arms are firmly attached and don't have any excessive movement.

6. Test the swing-back arms: Verify that the swing-back arms operate smoothly and securely. Swing them forward and backward to ensure they move freely and lock into place when needed.

7. Adjust the armrest height (if applicable): Some swing-back arms may have adjustable height settings. If this is the case, adjust the armrests to a comfortable height for the user. Follow the manufacturer's instructions for making the necessary adjustments.

8. Double-check the installation: Confirm that all screws or bolts are tightened properly, and there are no loose components that could pose a safety risk.

It's important to note that the installation process may vary slightly depending on the specific wheelchair model and the design of the swing-back arms you are installing. Always refer to the manufacturer's instructions for your particular wheelchair and armrests to ensure proper installation and safety. If you are unsure about any step or encounter difficulties during the process, consider seeking assistance from a qualified professional or contacting the manufacturer for guidance.
