Abstract: A shear cutting tool includes a housing, a hydraulic drive assembly at least partially supported in the housing, and a head assembly coupled to the housing. The housing has a first end, second end, base portion, and a handle extends from the housing. The handle supports a trigger. The hydraulic drive assembly is activated by the trigger and is configured to move a movable die relative to a stationary die. The head assembly is coupled to the second end of the housing and includes a clevis that supports the movable and stationary dies, a plurality of extensions, and a stop plate with a lower face. The extensions are coupled to the clevis and the stop plate is coupled to the extensions. The clevis has a support portion that, together with the lower face and the base portion, define a support plane.

Abstract: The present disclosure provides a power tool including a housing and a hydraulic drive assembly at least partially supported in the housing. The housing includes a handle that supports a switch that activates the tool. The hydraulic drive assembly includes a pump assembly operably coupled to the motor assembly, a reservoir configured to contain hydraulic fluid in fluid communication with the pump assembly and in which a baffle is supported, a cylinder in fluid communication with the pump assembly which supports an auto-return valve therein, and a piston disposed in the cylinder and biased to a first position by a piston spring. The pump assembly includes a manifold housing that at least partially defines an inlet passageway that fluidly communicates the pump assembly and the cylinder and supports an inlet check valve.
