Using this mounting bracket is simple. First, take your standard - sized servo motor. Wrap the bracket around the servo so that it grabs the mounting tabs. This will hold the servo securely. Then, use M3 or #4 - 40 screws (you'll need to get these separately) to attach the bracket to your desired surface. When choosing a servo, remember to check its mounting tab thickness. If the tabs are too thick, you may need to make some adjustments to get a proper fit. As for maintenance, keep the bracket clean from dust and debris. You can use a dry cloth to wipe it down. Store it in a dry place when not in use to prevent any damage.
