Principle of Operation
A trigger controls the PULL and RETURN strokes. When the trigger is pressed, hydraulic pressure is directed to PULL side of
the piston, and fastener installation begins. At the end of PULL stroke, before the trigger is released, piston uncovers fiats
of unloading valve, thus unloading pressure by allowing fiuid to fiow back to Powerig® Hydraulic Unit. When the trigger is
released at end of PULL stroke when fastener is installed, the pressure is directed to RETURN side of the piston and moves
piston forward. Nose assembly, with tool, is then pushed off fastener.
