5 Operation
5.1

System operation

In a battery tool the hydraulic pump is integrated. An electric motor operates the hydraulic pump. The
electric motor is energized by a battery pack or from an external electric power source. This pump
displaces hydraulic oil and can build up pressure. The hydraulic pump is connected directly to the
hydraulic cylinder.
The hydraulic cylinder contains a plunger that can move axially. If the cylinder is filled with oil from the
bottom, the piston moves out. If the cylinder is filled from the top, the piston moves in. The direction in
which the piston moves is controlled by the so-called deadman's handle. The deadman's handle can be
rotated by the user to control the movement. If the deadman's handle is released, it returns
automatically to the neutral position and stops the movement of the tool.
In tools like cutters, spreaders and combi tools the movement of the piston drives a mechanism to make
a cutting or spreading movement.
