The video shows a person using a wrench to tighten a bolt on a piece of machinery. The person is wearing a black glove on their left hand and is using a silver wrench to turn the bolt clockwise. The machinery appears to be red and black, and there is a black hose attached to it. The person's right hand is holding the wrench steady while their left hand turns the bolt. The background is blurry, but it seems to be an outdoor setting.
