ABSTRACT:
A manual hydraulic riveter includes a body, a lever pivoted to the body for moving a first piston in a fluid cylinder to force hydraulic fluid through a first fluid pipe to a hydraulic cylinder to further move a second piston and an actuating rod carrying a riveting unit. When released the lever, the second piston is returned by a spring to force hydraulic fluid out of the hydraulic cylinder through a third fluid pipe and a second fluid pipe to the fluid cylinder.
