Using the DJI Ronin-M gimbal is a breeze. First, attach your camera to the mounting plate securely. Then, use the handle bar to hold and control the gimbal as you move. You can use the remote control to make precise adjustments. When it comes to the tuning stand, even though the locking bolt is missing, it still works fine for balancing. Just be careful not to put too much pressure on it. As for maintenance, keep it clean and dry. After each use, store it in a safe place. And remember to charge the batteries (not included) using the provided charger when you get them.
