6.2 Functional description
Principle
The machine is a demolition hammer with a pneumatic percussion system.
It is driven by a gasoline engine.
The rotary movement of the drive engine is converted into a stroke movement
via a transmission and a crank gear.
The piston is moved forwards and backwards by the crank gear, this compresses
the air (forward movement) or generates a partial vacuum (backward move-
ment). Due to change in pressure the percussion piston is moved forward and
backwards (air cushion percussion system) and hits the tool.
The hood and operator's controls are decoupled from the percussion system by
a spring system. This spring system keeps vibrations away from the operator's
body if he for example presses his body against the hood while working.
Integrated shut-off device – RS (optional)
The machine has an integrated shut-off device for connecting to an external re-
mote cut-off.
Via the remote cut-off, you can switch off several machines from a central loca-
tion. This is for the safety of the operators, e.g. in track construction work.
If you wish to use your machine with a remote cut-off, please contact your
Wacker Neuson representative.
Low Vib (optional)
The machine has very low hand-arm vibration and allows fatigue-free working.
