To use this Ampeg SVT - 810E bass cabinet, first connect your bass guitar to the cabinet's input. Make sure the connections are secure. When you're done using it, unplug it properly. As for maintenance, keep it in a dry place away from direct sunlight and moisture. Since the tolex is ripped, be careful not to let anything further damage it. You can also periodically check the internal components for any loose parts, but if you're not sure, it's best to consult a professional.
