Using this E-Image EI-7103H heavy - duty fluid video head is quite straightforward. First, securely mount your camera on the head. Then, adjust the pan and tilt settings according to your shooting angle. You can use the pan drag dial to control the smoothness of the horizontal movement. Note that since one arm is missing, be extra careful when handling the head to avoid any imbalance. Also, because the pan drag dial is a bit sticky, don't force it too hard to prevent any damage. For maintenance, keep the head clean by using a soft, dry cloth to wipe off any dust or debris. If you notice any further issues with the pan drag dial, you can try applying a small amount of suitable lubricant. But make sure to follow the proper safety procedures when doing so.
