PRINCIPLE OF OPERATION

When the tool is connected to the power supply, depressing the electric actuator will simultaneously

start the pump and shift the directional valve. Hydraulic oil is then forced up and into the front side

of the head cylinder assy, causing the piston to move to the rear position. The internal components

of the tool are also moving with the piston to start the fastener installation. As the piston nears the

end of its stroke, it exposes flats on the unloading valve. These flats relieve the oil pressure and al-

lows the oil to return to the reservoir tank. When the fastener installation is completed, the electric

actuator is released causing the directional valve to shift back to its original position. Hydraulic oil is

then directed to the rear of the piston moving it and the internal components of the tool forward to

their original position.
