5 Operation
5.1

System operation

In a battery tool the hydraulic pump is integrated. The hydraulic pump is driven 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.
5.2 Carrying position
Refer to Fig. 2
Preferred carrying position of the tool is at battery compartment of carrying handle.
5.3 Charging the battery pack
• Study the instructions of the charger before charging the battery pack.
