In addition to incorporating many of the features of the 2581, both the model 2582 and 2583 feature an eccentric piston that allows for an improved center-to-edge measurement for tight clearance applications. The model 2583 has a longer stroke, providing for one-cycle installation of a wide range of fasteners, including BobTails.
Lightweight and compact tools are particularly adapted to installing fasteners in limited clearance areas.
An unloading valve, designed to relieve hydraulic pressure at end of the PULL stroke, is positioned by the piston.
