A man in a blue vest, jeans, and brown shoes operates a blue hand-operated machine on a paved surface. He pumps the lever while standing and holding onto it. Another man in a green shirt stands nearby, observing. In the background, there are two white pickup trucks parked in front of a light-colored building with windows. There is a striped bag beside the machine, and some hoses and round objects on the ground. The man in the blue vest steps away from the machine, and the man in green touches his arm.
