2480 & 2481 series Hydraulic Installation Tools (HK970)

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 flats of unloading valve, thus unloading pressure
by allowing fluid to flow 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.
